So what I have is , I have 20 questions and 5 answers of these questions , What I want to achieve is to get the answers uniquely , there will be
" a , b , c, d, e "
to choose for every question.
Everytime user enters the quiz , all the questions and answers will be loaded uniqely.
My main problem is I cant get unique answers ,
For example , for question 1
What is the day
I end up with same answers
a ) monday b) tuesday c) monday d)thursday e) saturday.....
I cant load different uniqe answers..
how is that possible , I tried splice array but it only makes things messed up.
You can do something like this..
var anwers:Array = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];
var selectedAnswers:Array = new Array(5); // array for selected answers
var tmp:Number = Math.floor(Math.random*5);
var correct:String = answers[0]; // let "Monday" be the correct answer
selectedAnswers[tmp] = correct; // correct answer set to a random position
for(var i:Number=0; i<5; i++){
tmp=Math.floor(Math.random*5);
if(selectedAnswers[i].equals(correct)) continue; //skip for the correct answer
if(selectedAnswers.indexOf(answers[tmp])<0){ // set answer if not present already
selectedAnswers[i] = answers[tmp];
} else {
i--; // loop again if answer is set earlier
}
}
Above will be completely random, but may take some time to select the last elements..
The following method will be quite fast, but not fully random
var anwers:Array = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];
var selectedAnswers:Array = new Array(5); // array for selected answers
var tmp:Number = Math.floor(Math.random*5);
var correctIndex:Number = 0; // let "Monday" be the correct answer
var correct:String = answers[correctIndex];
selectedAnswers[tmp] = correct; // correct answer set to a random position
var j:Number = correctIndex; // temporary index
var offset:Number = 2; // unique for this answer set
// so that the answers won't overlap for 5 choices
for(var i:Number=0; i<4; i++){ // not completely random (yet give random answers for specific cases)
tmp++;
if(tmp==5) tmp = 0;
j += offset;
if(j>answers.length) j -= answers.length;
selectedAnswers[tmp] = answers[j];
}
This assigns values from answers to selectedAnswers starting from a random index;

I receive the same duration & distance whether or not I am expecting to avoid highways or tolls
I suspect the issue is either in my order of operations, or the way I am calculating distance & duration
I have tried setting up setAvoid in two different ways (see code), as well as changed my if statements to accommodate what the HTML form (check box) might return.
I have also tried switching the if statement to "return formObject.avoid1"
this showed me that the if statement is functioning properly - so either the .setAvoid is not working the way I have written it, or the distance & duration calculations are not considering the setAvoid
function processForm(formObject) {
var allDestinations = [formObject.destination1, formObject.destination2, formObject.destination3, formObject.destination4];
var allDest = [formObject.dest1, formObject.dest2, formObject.dest3, formObject.dest4];
var numWaypoints = 0;
var waypoints = [];
for (var i=0; i<=allDestinations.length; ++i){
if (allDestinations[i] == "TRUE"){
numWaypoints ++;
waypoints.push(allDest[i]);
}
}
var mapObj = Maps.newDirectionFinder();
mapObj.setOrigin(formObject.origin)
.setDestination('my address, never changes');
//the purpose of legOne is to get the distance & duration from me to the input origin. I will always be the first and last stop. I do it this way because the input origin always needs to be the first stop. This prevents 'optimize waypoints' from altering the input origin.
var legOne = mapObj.getDirections();
var totalDistance = legOne["routes"][0]["legs"][0]["distance"]["value"];
var totalDuration = legOne["routes"][0]["legs"][0]["duration"]["value"];
for (var cc=0; cc<numWaypoints; ++cc){
mapObj.addWaypoint(waypoints[cc]);
}
if (formObject.optimize == "true"){
mapObj.setOptimizeWaypoints(true);
}
if (formObject.avoid1 == "yes"){
mapObj.setAvoid(Maps.DirectionFinder.Avoid.HIGHWAYS);
}
if (formObject.avoid2 == "yes"){
mapObj.setAvoid("tolls");
}
var directions = mapObj.getDirections();
var bestRoute = directions["routes"][0];
var numLegs = bestRoute["legs"].length;
for (var c=0; c<numLegs; ++c){
var legNum = directions["routes"][0]["legs"][c];
var legDistance = legNum["distance"]["value"];
var legDuration = legNum["duration"]["value"];
totalDistance += legDistance;
totalDuration += legDuration;
}
var miles = totalDistance * 0.000621371;
var driveTime = totalDuration / 60 / 60;
var numPallets = formObject.numPallets;
var parkTime = numWaypoints * (1/6);
var onOffLoadTime = numPallets * .5;
var totalTime = driveTime + parkTime + onOffLoadTime;
var dataArray = [miles, totalTime, driveTime, numPallets, onOffLoadTime, numWaypoints, parkTime];
return dataArray;
}
If we are in fact avoiding highways, I expect the duration to increase, but I get the same duration whether or not we avoid highways
Only one mode of setAvoid() can be set at a time, i.e., it is possible to avoid highways OR tolls, but not both. Workarounds for this exist within the API, but from what I've tested don't seem to be available in Apps Script.
Some testing:
var directions = Maps.newDirectionFinder()
.setOrigin('Times Square, New York, NY')
.setDestination('Space Needle, Seattle, WA')
Logger.log(directions.getDirections().routes[0].legs[0].duration.text) //1 day 18 hours
directions.setAvoid("highways")
Logger.log(directions.getDirections().routes[0].legs[0].duration.text) //2 days 8 hours
directions.setAvoid("tolls")
Logger.log(directions.getDirections().routes[0].legs[0].duration.text) //1 day 20 hours
This implies that either your if statements should be:
if (formObject.avoid1 == "yes"){
mapObj.setAvoid(Maps.DirectionFinder.Avoid.HIGHWAYS);
} else if (formObject.avoid2 == "yes"){
mapObj.setAvoid(Maps.DirectionFinder.Avoid.TOLLS);
}
(Prioritizes avoiding highways), or alternatively, your form should only include a single option for avoid (e.g., mapObj.setAvoid(formObj.avoid);). With your code as given, it's likely that avoid2 being "yes" causes setAvoid() to be set to avoid tolls, which may not be a factor along your route.
Update #2: Okay, I'm pretty sure my error in update #1 was because of indexing out of bounds over the array (I'm still not used to JS indexing at 0). But here is the new problem... if I write out the different combinations of the loop manually, setting the page index to 1 in moveItem() like so:
newForm.moveItem(itemsArray[0][0], 1);
newForm.moveItem(itemsArray[0][1], 1);
newForm.moveItem(itemsArray[0][2], 1);
newForm.moveItem(itemsArray[1][0], 1);
newForm.moveItem(itemsArray[1][1], 1);
newForm.moveItem(itemsArray[1][2], 1);
newForm.moveItem(itemsArray[2][0], 1);
...
...I don't get any errors but the items end up on different pages! What is going on?
Update #1:: Using Sandy Good's answer as well as a script I found at this WordPress blog, I have managed to get closer to what I needed. I believe Sandy Good misinterpreted what I wanted to do because I wasn't specific enough in my question.
I would like to:
Get all items from a page (section header, images, question etc)
Put them into an array
Do this for all pages, adding these arrays to an array (i.e: [[all items from page 1][all items from page 2][all items from page 3]...])
Shuffle the elements of this array
Repopulate a new form with each element of this array. In this way, page order will be randomized.
My JavaScript skills are poor (this is the first time I've used it). There is a step that produces null entries and I don't know why... I had to remove them manually. I am not able to complete step 5 as I get the following error:
Cannot convert Item,Item,Item to (class).
"Item,Item,Item" is the array element containing all the items from a particular page. So it seems that I can't add three items to a page at a time? Or is something else going on here?
Here is my code:
function shuffleForms() {
var itemsArray,shuffleQuestionsInNewForm,fncGetQuestionID,
newFormFile,newForm,newID,shuffle, sections;
// Copy template form by ID, set a new name
newFormFile = DriveApp.getFileById('1prfcl-RhaD4gn0b2oP4sbcKaRcZT5XoCAQCbLm1PR7I')
.makeCopy();
newFormFile.setName('AAAAA_Shuffled_Form');
// Get ID of new form and open it
newID = newFormFile.getId();
newForm = FormApp.openById(newID);
// Initialize array to put IDs in
itemsArray = [];
function getPageItems(thisPageNum) {
Logger.log("Getting items for page number: " + thisPageNum );
var thisPageItems = []; // Used for result
var thisPageBreakIndex = getPageItem(thisPageNum).getIndex();
Logger.log( "This is index num : " + thisPageBreakIndex );
// Get all items from page
var allItems = newForm.getItems();
thisPageItems.push(allItems[thisPageBreakIndex]);
Logger.log( "Added pagebreak item: " + allItems[thisPageBreakIndex].getIndex() );
for( var i = thisPageBreakIndex+1; ( i < allItems.length ) && ( allItems[i].getType() != FormApp.ItemType.PAGE_BREAK ); ++i ) {
thisPageItems.push(allItems[i]);
Logger.log( "Added non-pagebreak item: " + allItems[i].getIndex() );
}
return thisPageItems;
}
function shuffle(array) {
var currentIndex = array.length, temporaryValue, randomIndex;
Logger.log('shuffle ran')
// While there remain elements to shuffle...
while (0 !== currentIndex) {
// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex -= 1;
// And swap it with the current element.
temporaryValue = array[currentIndex];
array[currentIndex] = array[randomIndex];
array[randomIndex] = temporaryValue;
}
return array;
}
function shuffleAndMove() {
// Get page items for all pages into an array
for(i = 2; i <= 5; i++) {
itemsArray[i] = getPageItems(i);
}
// Removes null values from array
itemsArray = itemsArray.filter(function(x){return x});
// Shuffle page items
itemsArray = shuffle(itemsArray);
// Move page items to the new form
for(i = 2; i <= 5; ++i) {
newForm.moveItem(itemsArray[i], i);
}
}
shuffleAndMove();
}
Original post: I have used Google forms to create a questionnaire. For my purposes, each question needs to be on a separate page but I need the pages to be randomized. A quick Google search shows this feature has not been added yet.
I see that the Form class in the Google apps script has a number of methods that alter/give access to various properties of Google Forms. Since I do not know Javascript and am not too familiar with Google apps/API I would like to know if what I am trying to do is even possible before diving in and figuring it all out.
If it is possible, I would appreciate any insight on what methods would be relevant for this task just to give me some direction to get started.
Based on comments from Sandy Good and two SE questions found here and here, this is the code I have so far:
// Script to shuffle question in a Google Form when the questions are in separate sections
function shuffleFormSections() {
getQuestionID();
createNewShuffledForm();
}
// Get question IDs
function getQuestionID() {
var form = FormApp.getActiveForm();
var items = form.getItems();
arrayID = [];
for (var i in items) {
arrayID[i] = items[i].getId();
}
// Logger.log(arrayID);
return(arrayID);
}
// Shuffle function
function shuffle(a) {
var j, x, i;
for (i = a.length; i; i--) {
j = Math.floor(Math.random() * i);
x = a[i - 1];
a[i - 1] = a[j];
a[j] = x;
}
}
// Shuffle IDs and create new form with new question order
function createNewShuffledForm() {
shuffle(arrayID);
// Logger.log(arrayID);
var newForm = FormApp.create('Shuffled Form');
for (var i in arrayID) {
arrayID[i].getItemsbyId();
}
}
Try this. There's a few "constants" to be set at the top of the function, check the comments. Form file copying and opening borrowed from Sandy Good's answer, thanks!
// This is the function to run, all the others here are helper functions
// You'll need to set your source file id and your destination file name in the
// constants at the top of this function here.
// It appears that the "Title" page does not count as a page, so you don't need
// to include it in the PAGES_AT_BEGINNING_TO_NOT_SHUFFLE count.
function shuffleFormPages() {
// UPDATE THESE CONSTANTS AS NEEDED
var PAGES_AT_BEGINNING_TO_NOT_SHUFFLE = 2; // preserve X intro pages; shuffle everything after page X
var SOURCE_FILE_ID = 'YOUR_SOURCE_FILE_ID_HERE';
var DESTINATION_FILE_NAME = 'YOUR_DESTINATION_FILE_NAME_HERE';
// Copy template form by ID, set a new name
var newFormFile = DriveApp.getFileById(SOURCE_FILE_ID).makeCopy();
newFormFile.setName(DESTINATION_FILE_NAME);
// Open the duplicated form file as a form
var newForm = FormApp.openById(newFormFile.getId());
var pages = extractPages(newForm);
shuffleEndOfPages(pages, PAGES_AT_BEGINNING_TO_NOT_SHUFFLE);
var shuffledFormItems = flatten(pages);
setFormItems(newForm, shuffledFormItems);
}
// Builds an array of "page" arrays. Each page array starts with a page break
// and continues until the next page break.
function extractPages(form) {
var formItems = form.getItems();
var currentPage = [];
var allPages = [];
formItems.forEach(function(item) {
if (item.getType() == FormApp.ItemType.PAGE_BREAK && currentPage.length > 0) {
// found a page break (and it isn't the first one)
allPages.push(currentPage); // push what we've built for this page onto the output array
currentPage = [item]; // reset the current page to just this most recent item
} else {
currentPage.push(item);
}
});
// We've got the last page dangling, so add it
allPages.push(currentPage);
return allPages;
};
// startIndex is the array index to start shuffling from. E.g. to start
// shuffling on page 5, startIndex should be 4. startIndex could also be thought
// of as the number of pages to keep unshuffled.
// This function has no return value, it just mutates pages
function shuffleEndOfPages(pages, startIndex) {
var currentIndex = pages.length;
// While there remain elements to shuffle...
while (currentIndex > startIndex) {
// Pick an element between startIndex and currentIndex (inclusive)
var randomIndex = Math.floor(Math.random() * (currentIndex - startIndex)) + startIndex;
currentIndex -= 1;
// And swap it with the current element.
var temporaryValue = pages[currentIndex];
pages[currentIndex] = pages[randomIndex];
pages[randomIndex] = temporaryValue;
}
};
// Sourced from elsewhere on SO:
// https://stackoverflow.com/a/15030117/4280232
function flatten(array) {
return array.reduce(
function (flattenedArray, toFlatten) {
return flattenedArray.concat(Array.isArray(toFlatten) ? flatten(toFlatten) : toFlatten);
},
[]
);
};
// No safety checks around items being the same as the form length or whatever.
// This mutates form.
function setFormItems(form, items) {
items.forEach(function(item, index) {
form.moveItem(item, index);
});

I tested this code. It created a new Form, and then shuffled the questions in the new Form. It excludes page breaks, images and section headers. You need to provide a source file ID for the original template Form. This function has 3 inner sub-functions. The inner functions are at the top, and they are called at the bottom of the outer function. The arrayOfIDs variable does not need to be returned or passed to another function because it is available in the outer scope.
function shuffleFormSections() {
var arrayOfIDs,shuffleQuestionsInNewForm,fncGetQuestionID,
newFormFile,newForm,newID,items,shuffle;
newFormFile = DriveApp.getFileById('Put the source file ID here')
.makeCopy();
newFormFile.setName('AAAAA_Shuffled_Form');
newID = newFormFile.getId();
newForm = FormApp.openById(newID);
arrayOfIDs = [];
fncGetQuestionID = function() {
var i,L,thisID,thisItem,thisType;
items = newForm.getItems();
L = items.length;
for (i=0;i<L;i++) {
thisItem = items[i];
thisType = thisItem.getType();
if (thisType === FormApp.ItemType.PAGE_BREAK ||
thisType === FormApp.ItemType.SECTION_HEADER ||
thisType === FormApp.ItemType.IMAGE) {
continue;
}
thisID = thisItem.getId();
arrayOfIDs.push(thisID);
}
Logger.log('arrayOfIDs: ' + arrayOfIDs);
//the array arrayOfIDs does not need to be returned since it is available
//in the outermost scope
}// End of fncGetQuestionID function
shuffle = function() {// Shuffle function
var j, x, i;
Logger.log('shuffle ran')
for (i = arrayOfIDs.length; i; i--) {
j = Math.floor(Math.random() * i);
Logger.log('j: ' + j)
x = arrayOfIDs[i - 1];
Logger.log('x: ' + x)
arrayOfIDs[i - 1] = arrayOfIDs[j];
arrayOfIDs[j] = x;
}
Logger.log('arrayOfIDs: ' + arrayOfIDs)
}
shuffleQuestionsInNewForm = function() {
var i,L,thisID,thisItem,thisQuestion,questionType;
L = arrayOfIDs.length;
for (i=0;i<L;i++) {
thisID = arrayOfIDs[i];
Logger.log('thisID: ' + thisID)
thisItem = newForm.getItemById(thisID);
newForm.moveItem(thisItem, i)
}
}
fncGetQuestionID();//Get all the question ID's and put them into an array
shuffle();
shuffleQuestionsInNewForm();
}
A complex question :
I've got this code (not the complete code, but the essentials for the question, I think) :
var $pmm:String;
var $pms:String;
var $bmm:String;
var $bms:String;
function get haute1():String { return $pmm; };
function get haute2():String { return $pms; }
function get basse1():String { return $bmm; };
function get basse2():String { return $bms; };
accueil.todayHaute_txt.htmlText = haute1;
accueil.todayBasse_txt.htmlText = basse1;
accueil.todayHauteSecond_txt.htmlText = haute2;
accueil.todayBasseSecond_txt.htmlText = basse2;
"haute1" is an hour (in 24h format). Something like "13h25".
It changes everyday.
Question : How can put them in ascending order in AS3 ?
Example : If haute1 = 15h20, haute2= 6h00, basse1= 11h and basse2 = 17h, the function would put them in this order :
"haute2", then "basse1", then "haute1" and finally "basse2".
Thx
EDIT
I add this code that I have. is it helping you ?
/ Assigns hours and tidal heights
$pmm = convdateheure($tpbs[1 + $deltapm]);
$pms = convdateheure($tpbs[3 + $deltapm]);
$bmm = convdateheure($tpbs[2 - $deltapm]);
$bms = convdateheure($tpbs[4 - $deltapm]);
function convdateheure($valeur:Number):String
{
var $heure:Number = Math.floor($valeur);
var $minute:Number = Math.floor(Math.floor(($valeur - Math.floor($valeur)) * 100) * 0.6);
var hoursLabel:String = "", minsLabel:String = "";
if ($heure == 24) $heure = 0; // Check if at the 24 hour mark, change to 0
if ($heure < 10) hoursLabel += "0" + $heure.toString(); else hoursLabel = $heure.toString();
if ($minute < 10) minsLabel += "0" + $minute.toString(); else minsLabel = $minute.toString();
return hoursLabel + ":" + minsLabel;
}
If you want to order some dates written in some String format:
One way would be, depending on you date string format, just to push them into array and sort them as strings, then read them all.
Another way would be to first parse those strings into Date instances, and push their Date.time property to array, sort it, then do reverse: parse all time values from sorted array into new Date instances then use Date.toString or similar.
Assuming that $valuer is a numerical value:
var timesArray:Array = new Array();
var convertedTimesArray:Array = new Array();
function sortTimes():void{
timesArray.push($valuer);
timesArray.sort(Array.NUMERIC);
}
function convertTimes():void{
convertedTimesArray = []; // clear the array
for (var i:int = 0; i < timesArray.length; i++){
var s:String = convdateheure(timesArray[i]);
convertedTimesArray.push(s);
}
}
That should give you one array of actual times, sorted in numerical order, and one array sorted in the same numerical order, but converted to String values using your function.
I have a date like:
19/août/2016 (août = august)
And I have the following function which changes the month into a number:
function swapMonthForNumber(str:String):String {
//do the same line of code for every item in the array
for(var i:int=0;i<months.length;i++){
//i is the item, which is 0 based, so we have to add 1 to make the right month number
str = str.replace(months[i],String(+i+1));
}
//return the updated string
return str;
}
str = swapMonthForNumber(mySharedObject.data.theDate);
trace("Php will use this date :"+str);
So str will be 19/8/2016, but I want str to be 19/08/2016 (adding a 0 before the 8).
How can I do this?
Check out the reference of the Date class!
If forgot to mention this link : flash.globalization.DateTimeFormatter
DateTimeFormatter(requestedLocaleIDName:String, dateStyle:String = "long", timeStyle:String = "long")
Here is an example.
import flash.globalization.DateTimeFormatter;
var df:DateTimeFormatter = new DateTimeFormatter(LocaleID.DEFAULT, DateTimeStyle.SHORT, DateTimeStyle.NONE);
var currentDate:Date = new Date(2016,7,19);
var shortDate:String = df.format(currentDate);
trace (shortDate);
// output : 19/08/2016
DateTimeStyle
LocaleID
Adding leading zeros to a number is commonly called zero padding.
Below is a function to do this, from the answer here.
public function zeroPad(number:int, width:int):String {
var ret:String = ""+number;
while( ret.length < width )
ret="0" + ret;
return ret;
}
In your swapMonthForNumber function, in the for loop, swap the code for this:
var month = zeroPad(i + 1, 2);
str = str.replace(months[i], month);
I understand that cellTable in GWT performs this (Sort FlexTable Inquiry) and I was wondering if anyone knew a way to emulate some of the column sorting behaviour using a flexTable in UiApp.
In my case it is only necessary for the app to sort the column once at creation, not have it sortable by the user on click. I have included my flexTable creation code below:
var flexTable = app.createFlexTable()
.setStyleAttribute('marginTop', '10px')
.setCellPadding(5)
.setCellSpacing(2);
for(var i = 0;i<(size-1);i++){
var class = "class" + (i+1);
var classCode = classObjectsIndex[loggedInUser][class];
var text10 = statusObjectsIndex[classCode].classname;
var text11 = statusObjectsIndex[classCode].homeworkstatus;
var text12 = statusObjectsIndex[classCode].classcalendarlink;
var anchor = app.createAnchor('Calendar', text12)
.setTarget('_blank');
var calPanel = app.createAbsolutePanel()
.add(anchor);
flexTable.setText(i, 0, text10);
flexTable.setText(i, 1, text11);
flexTable.setWidget(i, 2, calPanel);
if(text11 == "No homework set for this class"){
flexTable.setRowStyleAttribute(i, "backgroundColor", "#96bcfd")
flexTable.setRowStyleAttribute(i, "color", "#000000");
}else{
flexTable.setRowStyleAttribute(i, "backgroundColor", "#eca8a3");
flexTable.setRowStyleAttribute(i, "color", "#FFFFFF");
};
}
app.add(flexTable);
Due to the way in which the table is populated sorting the array the values are pulled from will not help.
This the first question I have posted here, please be gentle. If I could ask it in a better way, I have overlooked an obvious resource to get my answer or if there is more information I need to provide please let me know!
EDIT//////////////////////////////////
I was having trouble sorting using the code provided, very helpfully, by Serge and so I approached it slightly differently and created individual objects for each row of data. The advice given by both Serge and Zig helped me end up with this working solution, many thanks!
//create flexTable
var flexTable = app.createFlexTable();
flexTable.setStyleAttribute('marginTop', '10px')
flexTable.setCellPadding(5);
flexTable.setCellSpacing(2);
//create empty table array to store rowObjects
var tableArray =[];
//create rowObjects
for(var i = 0; i<(size-1); i++){
var rowObject = {};
var class = 'class' + (i+1);
var classCode = classObjectsIndex[loggedInUser][class];
rowObject.className = statusObjectsIndex[classCode].classname;
rowObject.homeworkStatus = statusObjectsIndex[classCode].homeworkstatus;
rowObject.link = app.createAbsolutePanel().add(app.createAnchor('Calendar',statusObjectsIndex[classCode].classcalendarlink));
if(statusObjectsIndex[classCode].homeworkstatus == "No homework set for this class"){
rowObject.BGColor = "#96bcfd";
rowObject.color = "#000000";
}else{
rowObject.BGColor = "#eca8a3";
rowObject.color = "#FFFFFF";
}
tableArray.push(rowObject);
}
//sort objects in array by homework status
tableArray.sort(function (a, b) {
if (a.homeworkStatus > b.homeworkStatus)
return 1;
if (a.homeworkStatus < b.homeworkStatus)
return -1;
return 0;
});
//populate flextable
for(var i = 0;i<(size-1);i++){
flexTable.setText(i,0, tableArray[i].className);
flexTable.setText(i,1, tableArray[i].homeworkStatus);
flexTable.setWidget(i,2, tableArray[i].link);
flexTable.setRowStyleAttribute(i, 'color', tableArray[i].color);
flexTable.setRowStyleAttribute(i, 'backgroundColor', tableArray[i].BGColor);
};
app.add(flexTable);
Theres nothing that prevents you from sorting the source array first. Just store each 5 columns (3 data columns plus background/foreground colors) as rows in another array and sort that other array. After sort populate the table.
I fully agre with Zig on this, here is an example of such an implementation to help you figure out how to approach it. (code not tested but should be right)
var flexTable = app.createFlexTable()
.setStyleAttribute('marginTop', '10px')
.setCellPadding(5)
.setCellSpacing(2);
var array = [];
var t0 = [];
var t1 = [];
var t2 = [];
var color = [];
var BGcolor = [];
for(var i = 0;i<(size-1);i++){
var class = "class" + (i+1);
var classCode = classObjectsIndex[loggedInUser][class];
t0.push(statusObjectsIndex[classCode].classname);
t1.push(statusObjectsIndex[classCode].homeworkstatus);
t2.push(app.createAbsolutePanel().add(app.createAnchor('Calendar',statusObjectsIndex[classCode].classcalendarlink)));
if(statusObjectsIndex[classCode].homeworkstatus == "No homework set for this class"){
color.push("#000000")
BGcolor.push("#96bcfd")
}else{
color.push("#FFFFFF")
BGcolor.push("#eca8a3")
};
array.push(t0,t1,t2,color,BGcolor);
}
// sort the array here
array.sort();// use other sort parameter if you want, search SO for examples
for(var n in array){
flexTable.setText(i, 0, array[n][0]);
