How to populate the table dynamically and correctly with Ajax? - ajax

I have a form where the user submits a query and then have a Servlet that processes this query and returns the results in XML. With this result trying to populate a table dynamically via Ajax, for such, I use the following code below.
var thead = $("<thead>");
var rowsTHead = $("<tr>");
var tbody = $("<tbody>");
var numberOfColumns;
$(xml).find("head").each(function(){
var variable = $(this).find("variable");
numberOfColumns = variable.length;
for (var i = 0; i < variable.length; i++){
var name = $(variable[i]).attr("name");
rowsTHead.append($("<th>").html(name));
}
});
thead.append(rowsTHead);
$(xml).find("result").each(function(){
var literal = $(this).find("literal");
var rowsTBody = $("<tr class=\"even\">");
literal.length = numberOfColumns;
for (var j = 0; j < literal.length; j++){
var tdBody = $("<td>");
tdBody.html($(literal[j]).text());
rowsTBody.append(tdBody);
}
tbody.append(rowsTBody);
});
$(".tablesorter").empty()
.append(thead)
.append(tbody);
This code works perfectly until it was used in a UNION query. When using a UNION the returned xml comes in the following way http://pastebin.com/y7hXK1Zy
As can be observed, this query has 4 variables that are: gn1, indication1, gn2, indication2.
What is going wrong is that the values of all the variables being written in columns corresponding to gn1 and indication1.
What I wish I was to write the value of each variable in its corresponding column. I wonder what should I change in my code to make this possible.

You need to respect the name values of the binding elements, and relate them back to the columns that you correctly built from parsing the element. When you are doing the find "literal", you are skipping the parsing of the binding elements. You should find "binding", respect the name and look up which column to use based on that, and then for each of those, find the "literal" elements for the actual values.

Oracle APEX - Interactive Grid - get the return value of the select list from each record

My Interactive Grid has column caled "EMPL_STAT1".
I use the code below to get the return value of the select list from selected record.
Works fine but I was wondering how to change that code to get the return value of the select list from each record (not selected only) in "EMPL_STAT1" column?
Could you give me any advice?
var reg = apex.region('ig_emp').widget();
var grid = reg.interactiveGrid("getViews","grid");
var model = reg.interactiveGrid("getViews","grid").model;
var selectedRecords = grid.getSelectedRecords();
for (i = 0; i < selectedRecords.length; i++)
{
record = model.getRecord(selectedRecords[i][0]);
itemcodeField = model.getFieldKey("EMPL_STAT1");
alert(record[itemcodeField].v);
}
The Javascript you shared, gets the selected row records only.
Let's say my IG's static ID is igTest
var model = apex.region("igTest").widget().interactiveGrid("getViews", "grid").model;
model.forEach(function(igrow) {
console.log(igrow[model.getFieldKey("FIRST_NAME")]);
});
This will loop through all the records in the IG.

For loop to check values from two spreadsheets

I have two spreadsheets:
Column A on sheet 6th&7thRoster lists all IDs in a sample, contains 853 items.
Column C on sheet alreadySubmitted contains the IDs of users who've completed a task. Contains 632 items.
I'm trying to parse through both columns. If a user from Column A of sheet 6th&7thRoster matches a user from Column C of sheet sandboxAlreadySubmitted, I want to write the word "Yes" on Column I of the current row of sheet 6th&7thRoster. When using the code below, I'm not seeing not seeing any instances of the word "Yes" on Column I of 6th&7thRoster, even though I know there's multiple places where that should be the case.
function checkRoster() {
var mainSheet = SpreadsheetApp.openById('XXXXXXX');
var roster = mainSheet.getSheetByName('6th&7thRoster');
var submissions = mainSheet.getSheetByName('alreadySubmitted');
var rosterLastRow = roster.getLastRow();
var submissionsLastRow = submissions.getLastRow();
var rosterArray = roster.getRange('A2:A853').getValues();
var submissionsArray = submissions.getRange('C2:C632').getValues;
var i;
var x;
for (i = 1; i < 853; i++) {
for (x = 1; x < 632; x++){
if (rosterArray[i] == submissionsArray[x]){
roster.getRange(i, 9).setValue("Yes");
}
}
}
}
Feedback on how to solve and achieve this task will be much appreciated. For confidentiality, I cannot share the original sheets.
You want to compate the values of A2:A853 of 6th&7thRoster and C2:C632 of alreadySubmitted.
When the values of C2:C632 of alreadySubmitted are the same with the values of A2:A853 of 6th&7thRoster, you want to put Yes to the column "I".
If my understanding is correct, how about this modification? Please think of this as just one of several possible answers.
Modified script:
function checkRoster() {
var mainSheet = SpreadsheetApp.openById('XXXXXXX');
var roster = mainSheet.getSheetByName('6th&7thRoster');
var submissions = mainSheet.getSheetByName('alreadySubmitted');
var rosterLastRow = roster.getLastRow();
var submissionsLastRow = submissions.getLastRow();
var rosterArray = roster.getRange('A2:A853').getValues();
var submissionsArray = submissions.getRange('C2:C632').getValues(); // Modified
// I modified below script.
var obj = submissionsArray.reduce(function(o, [v]) {
if (v) o[v] = true;
return o;
}, {});
var values = rosterArray.map(function([v]) {return [obj[v] ? "Yes" : ""]});
roster.getRange(2, 9, values.length, values[0].length).setValues(values);
}
Flow:
Retrieve values from A2:A853 of 6th&7thRoster and C2:C632 of alreadySubmitted.
Create an object for searching the values from the values of alreadySubmitted.
Create the row values for putting to 6th&7thRoster.

LinqToExcel - Need to start at a specific row

I'm using the LinqToExcel library. Working great so far, except that I need to start the query at a specific row. This is because the excel spreadsheet from the client uses some images and "header" information at the top of the excel file before the data actually starts.
The data itself will be simple to read and is fairly generic, I just need to know how to tell the ExcelQueryFactory to start at a specific row.
I am aware of the WorksheetRange<Company>("B3", "G10") option, but I don't want to specify an ending row, just where to start reading the file.
Using the latest v. of LinqToExcel with C#
I just tried this code and it seemed to work just fine:
var book = new LinqToExcel.ExcelQueryFactory(#"E:\Temporary\Book1.xlsx");
var query =
from row in book.WorksheetRange("A4", "B16384")
select new
{
Name = row["Name"].Cast<string>(),
Age = row["Age"].Cast<int>(),
};
I only got back the rows with data.
I suppose that you already solved this, but maybe for others - looks like you can use
var excel = new ExcelQueryFactory(path);
var allRows = excel.WorksheetNoHeader();
//start from 3rd row (zero-based indexing), length = allRows.Count() or computed range of rows you want
for (int i = 2; i < length; i++)
{
RowNoHeader row = allRows.ElementAtOrDefault(i);
//process the row - access columns as you want - also zero-based indexing
}
Not as simple as specifying some Range("B3", ...), but also the way.
Hope this helps at least somebody ;)
I had tried this, works fine for my scenario.
//get the sheets info
var faceWrksheet = excel.Worksheet(facemechSheetName);
// get the total rows count.
int _faceMechRows = faceWrksheet.Count();
// append with End Range.
var faceMechResult = excel.WorksheetRange<ExcelFaceMech>("A5", "AS" + _faceMechRows.ToString(), SheetName).
Where(i => i.WorkOrder != null).Select(x => x).ToList();
Have you tried WorksheetRange<Company>("B3", "G")
Unforunatly, at this moment and iteration in the LinqToExcel framework, there does not appear to be any way to do this.
To get around this we are requiring the client to have the data to be uploaded in it's own "sheet" within the excel document. The header row at the first row and the data under it. If they want any "meta data" they will need to include this in another sheet. Below is an example from the LinqToExcel documentation on how to query off a specific sheet.
var excel = new ExcelQueryFactory("excelFileName");
var oldCompanies = from c in repo.Worksheet<Company>("US Companies") //worksheet name = 'US Companies'
where c.LaunchDate < new DateTime(1900, 0, 0)
select c;

Can I refer to items within a LINQ result set by index?

I'm trying to work with a LINQ result set of 4 tables retrieved with html agility pack. I'd like to process each one slightly differently by setting a variable for each (switch statement below), and then processing the rows within the table. The variable would ideally be the index for each of the tables in the set, 0 to 3, and would be used in the switch statement and to select the rows. I haven't been able to locate the index property, but I see it used in situations such as SelectChildNode.
My question is can I refer to items within a LINQ result set by index? My "ideal scenario" is the last commented out line. Thanks in advance.
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
String rtgChgType;
for (int ratingsChgTbl = 0; ratingsChgTbl < 4; ratingsChgTbl++)
{
switch (ratingsChgTbl)
{
case 0:
rtgChgType = "Upgrades";
break;
case 1:
rtgChgType = "Downgrades";
break;
case 2:
rtgChgType = "Coverage Initiated";
break;
case 3:
rtgChgType = "Coverage Reit/ Price Tgt Changed";
break;
//This is what I'd like to do.
var tblRowsByChgType = from row in ratingsChgs[ratingsChgTbl]
.SelectNodes("tr")
select row;
//Processing of returned rows.
}
}
ElementAt does what you're asking for. I don't recommend using it in your example, though, because each time you call it, your initial LINQ query will be executed. The easy fix is to have ratingsChgs be a List or Array.
You can also refactor out the switch statement. It is overkill when you only need to iterate through a list of items. Here is a possible solution:
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
var rtgChgTypeNames = new List
{
"Upgrades",
"Downgrades",
"Coverage Initiated",
"Coverage Reit/ Price Tgt Changed"
};
var changeTypes = ratingsChgs.Zip(rtgChgTypeNames, (changeType, name) => new
{
Name = name,
Rows = changeType.SelectNodes("tr")
});
foreach( var changeType in changeTypes)
{
var name = changeType.Name;
var rows = changeType.Rows;
//Processing of returned rows.
}
Also, why not store your rating change types in the HTML doc? It seems odd to have table information defined in the business logic.

HTMLAgilityPack ChildNodes index works, named node does not

I am parsing an XML API response with HTMLAgilityPack. I am able to select the result items from the API call.
Then I loop through the items and want to write the ChildNodes to a table. When I select
ChildNodes by saying something like:
sItemId = dnItem.ChildNodes(0).innertext
I get the proper itemId result. But when I try:
sItemId = dnItem.ChildNodes("itemId").innertext
I get "Referenced object has a value of 'Nothing'."
I have tried "itemID[1]", "/itemId[1]" and a veriety of strings. I have tried SelectSingleNode and ChildNodes.Item("itemId").innertext. The only one that has worked is using the index.
The problem with using the index is that sometimes child elements are omitted in the results and that throw off the index.
Anybody know what I am doing wrong?
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(#webHTMLeditor.TextXhtml);
HtmlNodeCollection tableRows = htmlDoc.DocumentNode.SelectNodes("//tr");
for (int i = 0; i < tableRows.Count; i++)
{
HtmlNode tr = tableRows[i];
HtmlNode[] td = new HtmlNode[2];
string xpath = tr.XPath + "//td";
HtmlNodeCollection cellRows = tr.SelectNodes(#xpath);
//td[0] = tr.ChildNodes[1];
//td[1] = tr.ChildNodes[3];
try
{
td[0] = cellRows[0];
td[1] = cellRows[1];
}
catch (Exception)
{ }
//etc
}
The code is used to extract data from a table, row by row, by cell per row.
I used the existing xpath and I altered it acording to my needs.
Good luck!
