Adding a variable to a Vertical Panel in GAS - user-interface

I am working on a master sheet which should have a UiApp embedded into the active sheet. I have tried coding the first part with the labels in the first row, but I am stuck with getting the names[i] to appear on the left hand side of the table under the Tasks label.
I intend to make check boxes appear for every name under each task label.
Here is the code below:
function showTable()
{
var ss = SpreadsheetApp.getActive();
var TL = ss.getRange('B3').getValue();
//SetFontWeight("bold") for TL < *This does not work either* >
var startDate = ss.getRange('B2').getValue();
var strStartDate = startDate.getDate() + "/" + (startDate.getMonth() + 1) + "/" + StartDate.getFullYear();
var counta = ss.getRange('B4').getValue();
var app = UiApp.createApplication().setHeight(375).setWidth(620)
.setTitle('This is ' + TL + "'s Team Tasks for " + strStartDate);
var panel = app.createAbsolutePanel().setId('panel').setHeight(355).setWidth(605)
.setStyleAttribute('background', 'lightCyan');
var names = ss.getRange('B11:B').getValues();
for (var i = 0; 0 < names.length; i++) **//This is the part that does not work**
{
var agents = app.createLabel(names[i]);
}
var handler1 = app.createServerHandler('btnCloseWindow');
var btnCloseWindow = app.createButton('Close Window').addClickHandler(handler1).setStyleAttribute('background', 'lightYellow');
handler1.addCallbackElement(panel);
var myLabel0 = app.createLabel('Tasks');
var myLabel1 = app.createLabel('HW');
var myLabel2 = app.createLabel('MU');
var myLabel3 = app.createLabel('MOV');
panel.add(myLabel0, 40, 12)
panel.add(myLabel1, 100, 12)
panel.add(myLabel2, 140, 12)
panel.add(myLabel3, 175, 12)
panel.add(agents, 40, 30)
panel.add(btnCloseWindow, 490, 320)
app.add(panel);
ss.show(app);
return app;
};
function btnCloseWindow(e)
{
var ss = SpreadsheetApp.getActive();
var app = UiApp.getActiveApplication();
app.close();
return app;
};
How do you make a vertical panel with the names?
The names are defined in col B11:B and the tasks are defined in the labels.
This is my first time making a UiApp so any help is very much appreciated!

Try it like this, I don't know how the whole think should look like but the part with the list of names is now right...
function showTable()
{
var ss = SpreadsheetApp.getActive();
var TL = ss.getRange('B3').getValue()
ss.getRange('B3').setFontWeight('bold')
var startDate = ss.getRange('B2').getValue();
var strStartDate = Utilities.formatDate(startDate, ss.getSpreadsheetTimeZone(), 'dd/mm/yyyy');
var counta = ss.getRange('B4').getValue();
var app = UiApp.createApplication().setHeight(375).setWidth(620)
.setTitle('This is ' + TL + "'s Team Tasks for " + strStartDate);
var panel = app.createAbsolutePanel().setId('panel').setHeight(355).setWidth(605)
.setStyleAttribute('background', 'lightCyan');
var handler1 = app.createServerHandler('btnCloseWindow');
var btnCloseWindow = app.createButton('Close Window').addClickHandler(handler1).setStyleAttribute('background', 'lightYellow');
handler1.addCallbackElement(panel);
var myLabel0 = app.createLabel('Tasks');
var myLabel1 = app.createLabel('HW');
var myLabel2 = app.createLabel('MU');
var myLabel3 = app.createLabel('MOV');
panel.add(myLabel0, 40, 12)
panel.add(myLabel1, 100, 12)
panel.add(myLabel2, 140, 12)
panel.add(myLabel3, 175, 12)
var names = ss.getRange('B11:B').getValues();
Logger.log(names)
for(i=0;i<names.length;++i){
Logger.log(names[i][0]);// names is a 2D array, you only want the first and only column
if(names[i][0]!=''){ // don't show if empty
panel.add(app.createLabel(names[i][0])); //add label to the panel
}
}
panel.add(btnCloseWindow, 490, 320)
app.add(panel);
ss.show(app);
};

var names = ss.getRange('B11:B').getValues();
Should be,
var names = ss.getRange('B11:B1').getValues();
How I researched,
var data = ss.getRange("b11:b1").getValues();
data.forEach(function(element,index,array){Logger.log(index + " " + element )});
Logs, "0 dog
1 cat
2 frog
3 fish
4 hamster
5 dog
6 cat
7 frog
8 fish
9 hamster
10 dog"

Assistance with loop inside a loop for a loan deduction schedule google apps

Our company offers soft loans to employees. I am trying to write some code that will set up a loan deduction schedule once a loan is approved. This is all done on google sheets. The schedule then can be linked to payroll etc.
The approved loans will appear in a format like this:-
Loans Approved - [Serial, Employee ID,Amount, Monthly Deductions,Requested Date,Deduction Start Date]
I am looking to build an array that will have the first 4 elements that repeat and the deduction month to increase by 1
So far this is my code
function myFunction() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Loans");
var range = sheet.getDataRange();
var data = range.getValues()
var lastRow = range.getLastRow()
var scheduleSheet = ss.getSheetByName("Schedule")
var scheuduleLastRow = scheduleSheet.getDataRange().getLastRow;
for(let i=1;i<lastRow;i++){
var serial = data [i][0]
var id = data [i][1]
var amount = data[i][2]
var monthlyRepayment = data [i][3]
var startDate = new Date (data [i][5])
var markScheduleDone = sheet.getRange(i+1,7)
var fullMonths = Math.floor(amount/monthlyRepayment)
var remainderMonth = (amount/monthlyRepayment)-fullMonths
var remainderAmount = Math.round(remainderMonth*monthlyRepayment)
for (let j=1;j<=fullMonths+1;j++){
var incrementalMonths = new Date(startDate.setMonth(startDate.getMonth()+1)) ;
}
var newArray = [serial,id,monthlyRepayment];
var remainderArray = [serial,id,remainderAmount];
var reptArray = Array(fullMonths).fill(newArray);
var finalArray = [...reptArray,remainderArray]
Logger.log(finalArray)
var toPasteto = scheduleSheet.getRange(scheuduleLastRow+1,1,finalArray.length,3)
toPasteto.setValues(finalArray)
markScheduleDone.setValue ("Done")
}
}
I am close but I cant figure out how to join the incrementalMonths to the finalarray.
This is the first time im using a loop within a loop
Also any guidance if I could have done this better?
Kinldy requesting some guidance
I'm not sure if this is exactly what you are looking for but try this.
Notice I fill the array finalArray with all the newArrays so I only have to setValues() once. Same with markDone.
I increment the month but if the day happens to fall outside the number of days in a month it will increment to another day. So for any 28 or 30 day months there should be another check but I didn't do that.
My particular style of coding is to always use a try {} catch() {} block, always terminate a line with semicolon ;, and to use let instead of var whenever possible.
function myFunction() {
try {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Loans");
var range = sheet.getDataRange();
var data = range.getValues()
var lastRow = range.getLastRow()
var scheduleSheet = ss.getSheetByName("Schedule")
var scheuduleLastRow = scheduleSheet.getDataRange().getLastRow();
let finalArray = [];
let markDone = [];
for(let i=1;i<lastRow;i++){
var serial = data [i][0];
var id = data [i][1];
var amount = data[i][2];
var monthlyRepayment = data [i][3];
var startDate = new Date (data [i][5]);
var fullMonths = Math.floor(amount/monthlyRepayment);
var remainderMonth = (amount/monthlyRepayment)-fullMonths;
var remainderAmount = Math.round(remainderMonth*monthlyRepayment);
let day = startDate.getDate();
if( day > 28 ) throw "This function has not adjusted for short months"
let month = startDate.getMonth();
let year = startDate.getFullYear();
let newArray = [];
for (let j=1;j<=fullMonths+1;j++){
month++;
if( month > 11 ) {
month = 0;
year++;
}
var date = new Date(year,month,day);
newArray.push([serial,id,monthlyRepayment,date])
}
newArray.push([serial,id,remainderAmount,date]);
finalArray = finalArray.concat(newArray);
Logger.log(newArray);
markDone.push(["Done"]);
}
sheet.getRange(2,7,markDone.length,1).setValues(markDone);
scheduleSheet.getRange(scheuduleLastRow+1,1,finalArray.length,4).setValues(finalArray);
}
catch(err) {
Logger.log(err)
}
}

Google Script - Macro to get data from a TABLE A and paste required values to Table B in sequence using LOOP

I seek help in finalizing a MACRO script for following task.
Basic requirements is to get data from 'Ref' tab (around 200 symbols) in a sequence to 'Mcontrol'!E3 (this tab imports a table from the Website)
From this table, sorted highest 2 values of Symbol/s is extracted and exported to 'OI EOD' tab,
i.e. required value is shown in 'OI EOD'! G5:K5.
Then, copy paste range 'OI EOD'! G5:K5 , to the matched row (symbol match to 'Mcontrol'!E3) in the table below ('OI EOD'!C6:C210).
I seek help in putting forEach condition in the macro. SO that next cycle of copy paste function is completed, for each new value in Cell_1 reference.
Hope ppl take notice of the help request from a novice and give good solution and guidance.

Not sure if understand the task as a whole, so here is a guess.
This way you can get values from some start to some end 'symbols' (or numbers) and put these values in correct rows on the 'OI EOD' sheet:
function main() {
var start = 1;
var end = 5;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var mcontrol_sheet = ss.getSheetByName('Mcontrol');
var oi_eod_sheet = ss.getSheetByName('OI EOD');
// get a list of all Symbols from column 'C' of the sheet 'OI EOD'
var symbols = oi_eod_sheet.getRange('c6:c').getValues().flat();
for (let i = start; i <= end; i++) {
// set the number i on the sheet 'Mcontrol' into the cell 'C3'
mcontrol_sheet.getRange('c3').setValue(i);
// wait to complete all the changes on the spreadsheet
SpreadsheetApp.flush();
// get the Symbol and Values from the range 'C5:K5' of the sheet 'OI EOD'
var [symbl, _, _, _, ...values] = oi_eod_sheet.getRange('c5:k5').getValues()[0];
// get the row index for this Symbol on the sheet 'Mcontrol'
var row = symbols.indexOf(symbl) + 6;
console.log({row}, {symbl}, {values});
// set the values on the sheet 'OI EOD' on the row with given index
oi_eod_sheet.getRange('g' + row + ':k' + row).setValues([values]);
}
}
It's up to you to decide how the start and end values could be defined. It can be values from two cells. Or it can be selected range. Or something else.

Add a status to each proccesed row in for loop that has an if statement with Google App Script

I've got a for loop in App script that is looking only at rows that have data in two columns. I'd like to set a status on each row that is actually processed, but the statuses get added to the wrong rows. When I add to i it adds to the whole length of the array, so I guess I shouldn't be trying to process each row, what am I doing wrong?
function auditReport() {
var sheetname = "Sheet1"; // name of data sheet ex. Form Responses 1
var colstoworkon = 10; // how many cols are filled with data f.e. by a form
var ss = SpreadsheetApp.getActiveSpreadsheet();
ss.setActiveSheet(ss.getSheetByName(sheetname));
var sheet = ss.getSheetByName(sheetname);
var data = sheet.getRange(3,1,sheet.getLastRow()-1,colstoworkon).getValues(); // starting with row 2 and column 1 as our upper-left most column,
//This makes it loops continuously and checks all not done rows
for (var i in data) {
if(data[i][1] && data[i][2]){//if email or copy are undefined just skip
var setStatus = sheet.getRange(i,4).setValue("done")
} // end of if
} // End of Loop
} //End of email function
Modification points:
In your script, from getRange(3,1,sheet.getLastRow()-1,colstoworkon), in this case, it is required to be getRange(3,1,sheet.getLastRow()-2,colstoworkon).
In the case of for (var i in data) {, i is the string type.
When you want to use sheet.getRange(i,4).setValue("done"), it is required to be sheet.getRange(Number(i) + 3, 4).setValue("done").
I thought that this might be the reason of your issue of but the statuses get added to the wrong rows..
In the case of if (data[i][1] && data[i][2]) {, if the value is 0, data[i][1] && data[i][2] is false.
When these points are reflected to your script, it becomes as follows.
Modified script:
function auditReport() {
var sheetname = "Sheet1";
var colstoworkon = 10;
var ss = SpreadsheetApp.getActiveSpreadsheet();
ss.setActiveSheet(ss.getSheetByName(sheetname));
var sheet = ss.getSheetByName(sheetname);
var data = sheet.getRange(3, 1, sheet.getLastRow() - 2, colstoworkon).getDisplayValues();
for (var i in data) {
if (data[i][1] && data[i][2]) {
var setStatus = sheet.getRange(Number(i) + 3, 4).setValue("done");
}
}
}
Or, your script can be also modified as follows. In this modification, done is put using the range list. By this, the process cost can be reduced a little.
function auditReport() {
var sheetname = "Sheet1";
var colstoworkon = 10;
var ss = SpreadsheetApp.getActiveSpreadsheet();
ss.setActiveSheet(ss.getSheetByName(sheetname));
var sheet = ss.getSheetByName(sheetname);
var data = sheet.getRange(3, 1, sheet.getLastRow() - 2, colstoworkon).getDisplayValues();
var ranges = data.map(([,b,c], i) => b && c ? `D${i + 3}` : "").filter(String);
if (ranges.length == 0) return;
sheet.getRangeList(ranges).setValue("done");
}

Google appscipt - Exporting multiple PDF with a for loop, using a sheet as a template, unexpected result

I'm trying to automate the pdf export of a sheet ('BL') which is filled depending on a cell value grabbed on a variable list on sheet 'EiBLdata' by 'i' on each loop.
It seems to work... more or less.
Instead of having 1st pdf with 1st value,
2nd pdf with 2nd value,
3rd pdf with 3rd value etc.
I get 1st pdf with 1st value,
2nd pdf with 1st value,
3rd pdf with 2nd value etc.
In the end only the 1st pdf has the right name, there is a shift in all the others and the last value isn't exported.
I'm quite a newbie with JavaScript and I admit there is a lot of copy/paste in my code, adapted to my purpose. I can't find what I'm doing wrong.
function printSelectedRange() {
var nomfeuille = "EiBLData"
var nomBL = "BL"
var cc = SpreadsheetApp.getActiveSpreadsheet();
var feuille = cc.getSheetByName(nomfeuille);
var BL = cc.getSheetByName(nomBL);
var tr = BL.getRange('B2').getValue();
var plage = feuille.getRange('A1:A15').getValues();
var cell0 = feuille.getRange(1,1).getValue();
BL.getRange('B2').setValue(cell0);
for (var i = 1; i <= 16; i++) {
var cell = feuille.getRange(i,1).getValue();
if (cell > 0) {
BL.getRange('B2').setValue(cell)

It looks like the loop runs faster than the spreadsheet calculation.

How do you do dynamic / dependent drop downs in Google Sheets?

How do you get a sub-category column to populate a drop down based on the value selected in the main category drop down in google sheets?
I googled around and couldn't find any good solutions, therefore I wanted to share my own. Please see my answer below.
You can start with a google sheet set up with a main page and drop down source page like shown below.
You can set up the first column drop down through the normal Data > Validations menu prompts.
Main Page
Drop Down Source Page
After that, you need to set up a script with the name onEdit. (If you don't use that name, the getActiveRange() will do nothing but return cell A1)
And use the code provided here:
function onEdit() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.getActiveSheet();
var myRange = SpreadsheetApp.getActiveRange();
var dvSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Categories");
var option = new Array();
var startCol = 0;
if(sheet.getName() == "Front Page" && myRange.getColumn() == 1 && myRange.getRow() > 1){
if(myRange.getValue() == "Category 1"){
startCol = 1;
} else if(myRange.getValue() == "Category 2"){
startCol = 2;
} else if(myRange.getValue() == "Category 3"){
startCol = 3;
} else if(myRange.getValue() == "Category 4"){
startCol = 4;
} else {
startCol = 10
}
if(startCol > 0 && startCol < 10){
option = dvSheet.getSheetValues(3,startCol,10,1);
var dv = SpreadsheetApp.newDataValidation();
dv.setAllowInvalid(false);
//dv.setHelpText("Some help text here");
dv.requireValueInList(option, true);
sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).setDataValidation(dv.build());
}
if(startCol == 10){
sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).clearDataValidations();
}
}
}
After that, set up a trigger in the script editor screen by going to Edit > Current Project Triggers. This will bring up a window to have you select various drop downs to eventually end up at this:
You should be good to go after that!
Caution! The scripts have a limit: it handles up to 500 values in a single drop-down list.

Last version of the script on GitHub
This solution is not perfect, but it gives some benefits:
Let you make multiple dropdown lists
Gives more control
Source Data is placed on the only sheet, so it's simple to edit
First of all, here's working example, so you can test it before going further.
Installation:
Prepare Data
Make the first list as usual: Data > Validation
Add Script, set some variables
Done!
Prepare Data
Data looks like a single table with all possible variants inside it. It must be located on a separate sheet, so it can be used by the script. Look at this example:
Here we have four levels, each value repeats. Note that 2 columns on the right of data are reserved, so don't type/paste there any data.
First simple Data Validation (DV)
Prepare a list of unique values. In our example, it is a list of Planets. Find free space on sheet with data, and paste formula: =unique(A:A)
On your mainsheet select first column, where DV will start. Go to Data > Validation and select range with a unique list.
Script
Paste this code into script editor:
function onEdit(event)
{
// Change Settings:
//--------------------------------------------------------------------------------------
var TargetSheet = 'Main'; // name of sheet with data validation
var LogSheet = 'Data1'; // name of sheet with data

var lrow = 2; // number of row where validation starts
var offsets = [1,1,1,2]; // offsets for levels

Here's set of variables that are to be changed, you'll find them in script:
var TargetSheet = 'Main'; // name of sheet with data validation
var LogSheet = 'Data2'; // name of sheet with data
var NumOfLevels = 7; // number of levels of data validation
var lcol = 9; // number of column where validation starts; A = 1, B = 2, etc.
var lrow = 2; // number of row where validation starts
var offsets = [1,1,1,1,1,1,1]; // offsets for levels
I suggest everyone, who knows scripts well, send your edits to this code. I guess, there's simpler way to find validation list and make script run faster.
Here you have another solution based on the one provided by #tarheel
function onEdit() {
var sheetWithNestedSelectsName = "Sitemap";
var columnWithNestedSelectsRoot = 1;
var sheetWithOptionPossibleValuesSuffix = "TabSections";
var activeSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var activeSheet = SpreadsheetApp.getActiveSheet();
// If we're not in the sheet with nested selects, exit!
if ( activeSheet.getName() != sheetWithNestedSelectsName ) {
return;
}
var activeCell = SpreadsheetApp.getActiveRange();
// If we're not in the root column or a content row, exit!
if ( activeCell.getColumn() != columnWithNestedSelectsRoot || activeCell.getRow() < 2 ) {
return;
}
var sheetWithActiveOptionPossibleValues = activeSpreadsheet.getSheetByName( activeCell.getValue() + sheetWithOptionPossibleValuesSuffix );
// Get all possible values
var activeOptionPossibleValues = sheetWithActiveOptionPossibleValues.getSheetValues( 1, 1, -1, 1 );
var possibleValuesValidation = SpreadsheetApp.newDataValidation();
possibleValuesValidation.setAllowInvalid( false );
possibleValuesValidation.requireValueInList( activeOptionPossibleValues, true );
activeSheet.getRange( activeCell.getRow(), activeCell.getColumn() + 1 ).setDataValidation( possibleValuesValidation.build() );
}
It has some benefits over the other approach:
You don't need to edit the script every time you add a "root option". You only have to create a new sheet with the nested options of this root option.
I've refactored the script providing more semantic names for the variables and so on. Furthermore, I've extracted some parameters to variables in order to make it easier to adapt to your specific case. You only have to set the first 3 values.
There's no limit of nested option values (I've used the getSheetValues method with the -1 value).
So, how to use it:
Create the sheet where you'll have the nested selectors
Go to the "Tools" > "Script Editor…" and select the "Blank project" option
Paste the code attached to this answer
Modify the first 3 variables of the script setting up your values and save it
Create one sheet within this same document for each possible value of the "root selector". They must be named as the value + the specified suffix.
Enjoy!
Edit: The answer below may be satisfactory, but it has some drawbacks:
There is a noticeable pause for the running of the script. I'm on a 160 ms latency, and it's enough to be annoying.
It works by building a new range each time you edit a given row. This gives an 'invalid contents' to previous entries some of the time
I hope others can clean this up somewhat.
Here's another way to do it, that saves you a ton of range naming:
Three sheets in the worksheet: call them Main, List, and DRange (for dynamic range.)
On the Main sheet, column 1 contains a timestamp. This time stamp is modified onEdit.
On List your categories and subcategories are arranged as a simple list. I'm using this for plant inventory at my tree farm, so my list looks like this:
Group | Genus | Bot_Name
Conifer | Abies | Abies balsamea
Conifer | Abies | Abies concolor
Conifer | Abies | Abies lasiocarpa var bifolia
Conifer | Pinus | Pinus ponderosa
Conifer | Pinus | Pinus sylvestris
Conifer | Pinus | Pinus banksiana
Conifer | Pinus | Pinus cembra
Conifer | Picea | Picea pungens
Conifer | Picea | Picea glauca
Deciduous | Acer | Acer ginnala
Deciduous | Acer | Acer negundo
Deciduous | Salix | Salix discolor
Deciduous | Salix | Salix fragilis
...
Where | indicates separation into columns.
For convenience I also used the headers as names for named ranges.
DRrange A1 has the formula
=Max(Main!A2:A1000)
This returns the most recent timestamp.
A2 to A4 have variations on:
=vlookup($A$1,Inventory!$A$1:$E$1000,2,False)
with the 2 being incremented for each cell to the right.
On running A2 to A4 will have the currently selected Group, Genus and Species.
Below each of these, is a filter command something like this:
=unique(filter(Bot_Name,REGEXMATCH(Bot_Name,C1)))
These filters will populate a block below with matching entries to the contents of the top cell.
The filters can be modified to suit your needs, and to the format of your list.
Back to Main: Data validation in Main is done using ranges from DRange.
The script I use:
function onEdit(event) {
//SETTINGS
var dynamicSheet='DRange'; //sheet where the dynamic range lives
var tsheet = 'Main'; //the sheet you are monitoring for edits
var lcol = 2; //left-most column number you are monitoring; A=1, B=2 etc
var rcol = 5; //right-most column number you are monitoring
var tcol = 1; //column number in which you wish to populate the timestamp
//
var s = event.source.getActiveSheet();
var sname = s.getName();
if (sname == tsheet) {
var r = event.source.getActiveRange();
var scol = r.getColumn(); //scol is the column number of the edited cell
if (scol >= lcol && scol <= rcol) {
s.getRange(r.getRow(), tcol).setValue(new Date());
for(var looper=scol+1; looper<=rcol; looper++) {
s.getRange(r.getRow(),looper).setValue(""); //After edit clear the entries to the right
}
}
}
}
Original Youtube presentation that gave me most of the onEdit timestamp component:
https://www.youtube.com/watch?v=RDK8rjdE85Y
Continuing the evolution of this solution I've upped the ante by adding support for multiple root selections and deeper nested selections. This is a further development of JavierCane's solution (which in turn built on tarheel's).

As Javier says:
Create the sheet where you'll have the nested selectors
Go to the "Tools" > "Script Editor…" and select the "Blank project"
option
Paste the code attached to this answer
Modify the constants at the top of the script setting up your values
and save it
Create one sheet within this same document for each possible value of
the "root selector". They must be named as the value + the specified
suffix.
And if you wanted to see it in action I've created a demo sheet and you can see the code if you take a copy.
