I have a 2D array which I want to send to a php page with $.ajax.
This is the code which creates the array:
for (var i = 0; i<rowlen; i++) {
if (breakcheck) {
break;
}
for (var j = 0; j<=columnlen; j++) {
thtext = columnheads.eq(j).text();
current_td = $(newrows[i]).find("td").eq(j);
if (current_td.find("input").length >0) {
rowdata[i,thtext] = current_td.find("input").val().trim();
if (rowdata[i,thtext] =='') {
alert("You must complete all fields");
breakcheck = true;
break;
}
} else {
rowdata[i,thtext] ='nada';
}
}//inner loop
}//outer loop
The array is filled properly with the nested loops and the I use JSON.stringify to format it. However when the ajax call is made all that is sent is an empty object ([]). What's wrong?
I might be wrong, but arr[i,j] is not the way to use multidimensional arrays in C-style languages. That would be arr[i][j].
IMHO what arr[i,j] will do is function as comma operator and use only j as an index.
OK I solved this by declaring r as an object (var r = {}) instead of declaring it as an array (var r = []). Thanks for the help.

I made a small search box to retrieve values from a datasheet. For some reason it only loops once. Also this is the first time I'm trying something in google sheets, so if I want to search a string in column B, then the SEARCH_COL_IDX should be 1 right?
I put in a few loggers to check the process. I do see Logger.log(str), Logger.log("Check") and Logger.log("Check2). The latter two only once, where it should be multiple times imo. The Logger.log(row[#]) I don't get to see at all, which means it doesn't find anything.
I also tried doing if(row[SEARCH_COL_IDX] = str) { to see where it is looking. Than the Logger.log(row[#]) do come back, but from different rows AND columns. I am doing something wrong, but I can't find it.. any suggestions?
var SPREADSHEET_NAME = "Database";
var SEARCH_COL_IDX = 1;
var RETURN_COL_IDX= 1;
function searchStr(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var formSS = ss.getSheetByName("Userform");
var str = formSS.getRange("d17").getValue();
Logger.log(str);
var values = ss.getSheetByName("Database").getDataRange().getValues();
for (var i = 0; i < values.length; i++) {
Logger.log("check");
var row = values[i];
Logger.log("check2");
if(row[SEARCH_COL_IDX] == str) {
formSS.getRange("d3").setValue(row[0]);
Logger.log(row[0]);
formSS.getRange("d5").setValue(row[1]);
Logger.log(row[1]);
formSS.getRange("d7").setValue(row[2]);
Logger.log(row[2]);
formSS.getRange("d9").setValue(row[3]);
Logger.log(row[3]);
formSS.getRange("d11").setValue(row[4]);
Logger.log(row[4]);
formSS.getRange("d13").setValue(row[5]);
Logger.log(row[5]);
}
Logger.log("nothing found");
return row[RETURN_COL_IDX];
}
Your function has a return command in the last line of your loop block.
I'm currently writing a statistic spreadsheet script for my guild, which reads out the class of one person and counts it on the statistic sheet.
For some reason the for loops aren't working. When I execute the script, it does nothing. Everything before the for loop seems to work. I have used the debugger, and set a debug point from the point of the for loop and the window is opening and closing after like 1 second.
This is my code as of now:
function addToStatistik() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var source_sheet = spreadsheet.getSheetByName("Raid Montag");
var source_range_names = source_sheet.getRange("C4:C13");
var source_range_setup_boss1 = source_sheet.getRange("M4:M13");
var target_sheet = spreadsheet.getSheetByName("Statistik");
var target_range_names = target_sheet.getRange("A4:A31");
var target_range_boss1 = target_sheet.getRange("K4:S31");
target_sheet.getRange(2,1).setValue("Debug1"); //testing stuff
for (var i=0; i < source_range_names.length; i++) {
for (var j=0; j < target_range_names.length; j++) {
if (source_range_names[i][0] == target_range_names[j][0]) {
if (source_range_setup_boss1[i][0].indexOf("War") > -1) {
target_sheet.getRange(9,5).setValue("TEST");
}
}
}
}
}
Someone can find any errors in there? I can't find anything and google also isnt helping me.
You are getting the range, but not the values. This line:
var source_range_names = source_sheet.getRange("C4:C13");
gets a range, but not any values.
Should be:
var source_range_names = source_sheet.getRange("C4:C13").getValues();
The outer loop never loops. There is no length of a range.
for (var i=0; i < source_range_names.length; i++) {
You don't need to change the above line, but currently the variable source_range_names is a range, and not a 2D array of values.
Before you iterate you need to get the values of the range, to achieve this you need to use the method getValues() or getDisplayValues():
function leFunction() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var source_sheet = spreadsheet.getSheetByName("Raid Montag");
var source_range_names = source_sheet.getRange("A1:C13");
var values_range_names = source_range_names.getDisplayValues();
Logger.log(values_range_names);
for (var i=0; i < values_range_names.length; i++) {
// Do Something
}
}
.proto file structure
message repetedMSG
{
required string data = 1;
}
message mainMSG
{
required repetedMSG_id = 1;
repeated repetedMSG rptMSG = 2;
}
I have one mainMSG and in it too many (suppose 10) repetedMSG are present.
Now i want to delete any particular repetedMSG (suppose 5th repetedMSG )from mainMSG. For this i tried 3 ways but none of them worked.
for (int j = 0; j<mainMSG->repetedMSG_size(); j++){
repetedMSG reptMsg = mainMsg->mutable_repetedMSG(j);
if (QString::fromStdString(reptMsg->data).compare("deleteMe") == 0){
*First tried way:-* reptMsg->Clear();
*Second tried Way:-* delete reptMsg;
*Third tried way:-* reptMsg->clear_formula_name();
break;
}
}
I get run-time error when i serialize the mainMSG for writing to a file i.e. when execute this line
mainMSG.SerializeToOstream (std::fstream output("C:/A/test1", std::ios::out | std::ios::trunc | std::ios::binary)) here i get run-time error
You can use RepeatedPtrField::DeleteSubrange() for this. However, be careful about using this in a loop -- people commonly write code like this which is O(n^2):
// BAD CODE! O(n^2)!
for (int i = 0; i < message.foo_size(); i++) {
if (should_filter(message.foo(i))) {
message.mutable_foo()->DeleteSubrange(i, 1);
--i;
}
}
Instead, if you plan to remove multiple elements, do something like this:
// Move all filtered elements to the end of the list.
int keep = 0; // number to keep
for (int i = 0; i < message.foo_size(); i++) {
if (should_filter(message.foo(i))) {
// Skip.
} else {
if (keep < i) {
message.mutable_foo()->SwapElements(i, keep)
}
++keep;
}
}
// Remove the filtered elements.
message.mutable_foo()->DeleteSubrange(keep, message.foo_size() - keep);
I get data from a $.ajax call but cant work correctly with the data of it. Here is my code.
function OnSuccessResultSet(data, status) {
var output;
for (var i in data.recordset) {
output += "<li><a href='#'>";
for (var j = 0; j < metaName.length; j++) {
var testVar = metaName[j];
output += " <h2>" + data.recordset[i].testVar+ "</h2>";
alert(data.recordset[i].testVar);
alert(testVar);
alert(data.recordset[i].LABEL);
};
output += "</a></li>";
}
$(output).appendTo("#content1");
$('#content1').listview('refresh');
}
The first alert gives me an undefined back. Second alert gives me LABEL back and third one gives me the value of LABEL. My metaName has all attribute values for my element from recordset. I fill also my metaName array with a $.ajax call.
I dont find my mistake. :/
I think you need to use bracket notation instead of dot notation as the member operator here as the key you are looking for is stored in the variable testVar
alert(data.recordset[i][testVar]);
Ex
function OnSuccessResultSet(data, status) {
var output, testVar;
for (var i in data.recordset) {
output += "<li><a href='#'>";
for (var j = 0; j < metaName.length; j++) {
testVar = metaName[j];
output += " <h2>" + data.recordset[i][testVar]+ "</h2>";
};
output += "</a></li>";
}
$(output).appendTo("#content1");
$('#content1').listview('refresh');
}
I have an object with large number of similar fields (like more than 10 of them) and I have to assign them values from an array of variable length. The solution would be either a huge nested bunch of ifs based on checking length of array each time and assigning each field
OR
a chain of ifs checking on whether the length is out of bounds and assigning each time after that check.
Both seem to be repetitive. Is there a better solution ?
If you language has switch/case with fallthrough, you could do it like this:
switch(array.length){
case 15: field14 = array[14];
case 14: field13 = array[13];
case 13: field12 = array[12];
// etc.
case 1: field0 = array[0];
case 0: break;
default: throw Exception("array too long!");
}
for (int i = 0; i < fieldCount; i++)
fields[i].value = array[i];
That is to say, maintain an array of fields that corresponds to your array of values.
If your language supports delegates, anonymous functions, that sort of thing, you can use those to clean it up. For example, in C# you could write this:
string[] values = GetValues();
SomeObject result = new SomeObject();
Apply(values, 0, v => result.ID = v);
Apply(values, 1, v => result.FirstName = v);
Apply(values, 2, v => result.LastName = v);
// etc.
The apply method would look like:
void Apply(string[] values, int index, Action<string> action)
{
if (index < values.Length)
action(values[index]);
}
This is obviously language-dependent, but something to think about regardless.
Another very simple option that we might be overlooking is, if you are actually trying to initialize an object from this value array (as opposed to update an existing object), to just accept the default values if the array isn't large enough.
C# example:
void CreateMyObject(object[] values)
{
MyObject o = new MyObject();
o.ID = GetValueOrDefault<int>(values, 0);
o.FirstName = GetValueOrDefault<string>(values, 0);
o.LastName = GetValueOrDefault<string>(values, 0);
// etc.
}
void GetValueOrDefault<T>(object[] values, int index)
{
if (index < values.Length)
return (T)values[index];
return default(T);
}
Sometimes the dumb solution is the smartest choice.
If your fields are declared in the same order of the array's elements, you could use reflection (if available in your language) to set these values. Here is an example of how you could do it in Java:
// obj is your object, values is the array of values
Field[] fields = obj.getClass().getFields();
for (int i = 0; i < fields.length && i < values.length; ++i) {
fields[i].set(obj, values[i]);
}
