I use hierarhical Kendo Grid.
http://demos.telerik.com/kendo-ui/grid/hierarchy
Nested grids are created with such function:
function detailInit(e) {
$("<div/>").appendTo(e.detailCell).kendoGrid({
name: "nestedGrid",
dataSource: {
...
},
columns: [
...
}).addClass("nested-grid-class");
How can I access the grid in another function? For example:
$(window).load(function() {
var grid = $(".nested-grid-class").data("kendoGrid");
alert('grid = ' + grid); // grid = undefined
var grid = $("nestedGrid").data("kendoGrid");
alert('grid = ' + grid); // grid = null
var grid = $("#nestedGrid").data("kendoGrid");
alert('grid = ' + grid); // grid = null
var grid = $("[name='nestedGrid']").data("kendoGrid");
alert('grid = ' + grid); // grid = null
});
The way proposed by Sandman doesn't work too
var grid = $("#MainGrid").data("kendoGrid");
alert('MainGrid = ' + grid); // ok
var parentRows = grid.tbody.find("tr.k-master-row");
alert('parentRows = ' + parentRows); // ok
parentRows.each(function (e) {
var row = $(this).next("tr");
alert('row = ' + row); // ok
if (row.hasClass("k-detail-row")) {
var nestedGrid = row.find(".k-grid").data("kendoGrid");
alert('nestedGrid = ' + nestedGrid); // undefined
var nestedGrid1 = row.find(".nested-grid-class").data("kendoGrid");
alert('nestedGrid1 = ' + nestedGrid1); // undefined
}
});
In order to access the nested grid for each row of the grid you could use the following:
var grid = $("#grid").data("kendoGrid");
var parentRows = grid.tbody.find("tr.k-master-row");
This should get you all parent rows. Then you can iterate over these using .each in order to access the child grid within:
parentRows.each(function(e){
var row = $(this).next("tr");
if(row.hasClass("k-detail-row")){
var nestedGrid = row.find(".k-grid").data("kendoGrid");
// EDIT: In your case, you may need to get by class - UNTESTED
// var row.find(".nested-grid-class").data("kendoGrid");
//access nested grid data here
}
});
EDIT
I have prepared an example based on the initial Dojo you sent through in your question which logs each initialised nested grid in the console. (NOTE: Both '.k-grid' and '.nested-grid-class' were valid selectors).
The issue for you is that only the first row was initialised in the dataBound event therefore meaning it was the only row to have a nested grid created. I have extended the example further so that all nested grids will be initialised during the dataBound function (this.expandRow(this.tbody.find("tr.k-master-row"));).
If you examine the console now, you will see the list of 6 parent rows, and 6 lists containing each nested grid datasource.

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);
},

);

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();
}
I have 2 'time' inputs for a start and end time.
When both inputs are completed I am wanting the 'total' field to automatically show the total between start and end (e.g 8 hours)
<input type='time' value="09:00" id="MondayStart" name='MondayStart' class='form-control'>
<input type='time' value="17:00" name='MondayEnd' id="MondayEnd" class='form-control'>
<input type="text" name="total">
I have tried following this script (http://jsbin.com/emoziw/1/edit?html,js,output) but cannot seem to change it to time
You have a default value so this is good.
You need to do something like this (using jQuery) :
$(".form-control").on('change', ()=>{
var $this = $(this);
var sum;
sum = /*do the sum calculation here*/;
$('input[name="total"]').eq(0).val(sum);
//if you put an id to the total then you can just use $(id here).val(sum)
});
This will, when the change event is triggered on any element having the form-control class, update the sum automatically.
PS:
I suggest to put a default value on the sum's holder (being of course the sume of the default values)
EDIT
I'd like to help you with the time calculation, so I made functions :
function doCalc($jq){//pass in the jqSelection that gets the two input
var $beg = $jq.eq(0);//first element with this class
var $end = $jq.eq(1);//second element with this class
var beg_t = {
h: getH($beg),
m: getM($beg)
}
var end_t = {
h: getH($end),
m: getM($end)
}
var elapsed = {
h: end_t.h - beg_t.h,
m: end_t.m - beg_t.m
}
return ""+elapsed.h+":"+elapsed.m;//so it can be used with what's above
}
/
function getH($t){
var str = $t.val();
return str.replace(/(\d{2}):(\d{2})/,"$1");
}
function getM($t){
var str = $t.val();
return str.replace(/(\d{2}:(\d{2})/,"$2");
}
EDIT 2:
If you want you can pass to the onchange EH a function pointer (therefore you can also call the function without having to trigger the event) :
function updateSum(){
var $this = $(".form-control");
var sum;
sum = doCalc($this);
$('input[name="total"]').eq(0).val(sum);
//if you put an id to the total then you can just use $(id here).val(sum)
}
therefore you can have :
$(document).ready(()=>{
updateSum();
$(".form-control").on('change', updateSum);
});
EDIT 3:
()=>{/*...*/} is just the ES6 way to declare an anonymous function, you can replace them with function(){/*...*/} if you're more comfortable with it.
EDIT 4 aka RECAP :
If you're a bit lost after this answer, here's a recap of the functions you need to add to your website :
##Regex based input processing##
function getH($t){
var str = $t.val();
return str.replace(/(\d{2}):(\d{2})/,"$1");
}
function getM($t){
var str = $t.val();
return str.replace(/(\d{2}:(\d{2})/,"$2");
}
##Calculation##
function doCalc($jq){//pass in the jqSelection that gets the two input
var $beg = $jq.eq(0);//first element with this class
var $end = $jq.eq(1);//second element with this class
var beg_t = {
h: getH($beg),
m: getM($beg)
}
var end_t = {
h: getH($end),
m: getM($end)
}
var elapsed = {
h: end_t.h - beg_t.h,
m: end_t.m - beg_t.m
}
return ""+elapsed.h+":"+elapsed.m;//so it can be used with what's above
}
##Update function##
function updateSum(){
var $this = $(".form-control");
var sum;
sum = doCalc($this);
$('input[name="total"]').eq(0).val(sum);
//if you put an id to the total then you can just use $(id here).val(sum)
}
##Event Handling and Call##
$(document).ready(function(){
updateSum();
$(".form-control").on('change', updateSum);
});
Serge's solution here seemed like the way to go about this, but I'm a bit afraid that my circumstances may be too different...
I have a button where users can add a new set of rows with controls to a FlexTable, in order to allow them to insert a new member into a record set. After designing and building the app to do this (and despite assurances to the contrary), a requirement was then added for the users to be able to edit the record sets at a later date.
I've finally managed to get the data retrieved and correctly displayed on the Ui - for single member record sets. As a final stage, I am now attempting to extend this to accommodate record sets having more than one member. Obviously this requires determining how many members there are in the record set, and then adding the new rows/control group to the FlexTable, before loading the member into each control group.
So within this routine, (depending on how many members there are) I may need to trigger the same callback, which the user normally does with a button. However, the difference with Serge's fine example, is that his code triggers the checkbox callback at the end of his routine once all the Ui components are in place. My situation needs to do this on the fly - and so far I'm getting 'Unexpected error', which suggests to me that the Ui is not able to update with the added FlexTable controls before my code attempts to assign values to them.
Does anyone have any insight into this problem? Is my only recourse to completely re-build a fixed Ui and dispense with the dynamic rowset model?
Code follows -
1. event for adding controls:
var app = UiApp.getActiveApplication();
var oFlexGrid = app.getElementById('ExpenseDetail');
var oRowCount = app.getElementById('rowCount');
var oScriptDBId = app.getElementById('scriptDBId');
var iRows = parseInt(e.parameter.rowCount);
var sVId = e.parameter.scriptDBId;
var vGridDefs = loadArrayById(sVId); //retrieve upload definition array from ScriptDB
var vControlNames = [];
if (isOdd(iRows)){
var sColour = 'AliceBlue';
} else {
var sColour = 'LavenderBlush';
};
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.setRowStyleAttributes(0,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(1,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(2,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(3,{'backgroundColor':sColour});
var vExpenseDef = Get_NamedRangeValues_(CONST_SSKEY_APP,'UIAPP_GridExpense');
iRows = iRows+1;
vControlNames = CreateGrid_MixedSet_(iRows, vExpenseDef, oFlexGrid, app);
oRowCount.setText(iRows.toString()).setValue(iRows.toString());
//SOME INCONSEQUENTIAL CODE REMOVED HERE, LET ME KNOW IF YOU NEED IT
vGridDefs = vGridDefs.concat(vControlNames); // unify grid definition arrays
var sAryId = saveArray('expenseFieldDef', vGridDefs);
oScriptDBId.setText(sAryId).setValue(sAryId); //store array and save ScriptDB ID
if (e.parameter.source == 'btnExpenseAdd'){
hideDialog(); //IGNORE CHEKCBOX-DRIVEN CALLS
};
return app;
2. routine that calls the event
var app = UiApp.getActiveApplication();
var oPanelExpense = app.getElementById('mainPanelExpense');
var oPanelIncome = app.getElementById('mainPanelIncome');
var oPanelEdit = app.getElementById('mainPanelEdit');
var chkExpenseAdd= app.getElementById('chkExpenseAdd');
var bExpenseTrigger = e.parameter.chkExpenseAdd;
var sVoucherId = nnGenericFuncLib.cacheLoadObject(CACHE_EDIT_VOUCHERID);
var sVoucher = e.parameter.ListSearch1Vouchers;
var aryVoucherInfo = getVoucherEditDetail(sVoucherId);
//SAVE FOR RECORD MARKING CALLBACK
nnGenericFuncLib.cacheSaveObject(CACHE_EDIT_OLDRECORDS, JSON.stringify(aryVoucherInfo), CACHE_TIMEOUT);
sVoucher = nnGenericFuncLib.textPad(sVoucher, '0', 7);
var bExp = (sVoucher.substring(0,2) == '03')
var oRowCount = app.getElementById('rowCount');
var iRowCount = parseInt(e.parameter.rowCount);
var sControlName = '';
var vControlVal = '';
var iExpIdx = 0;
var sControlType = '';
var oControl = '';
var vSummaryTotal = 0;
for (var iVal in aryVoucherInfo){
sControlName = aryVoucherInfo[iVal][2];
vControlVal = aryVoucherInfo[iVal][3];
switch (sControlName){
case 'ESUM60':
vSummaryTotal = vControlVal;
break;
case 'EXUSRN':
continue; //DON'T OVERWRITE CURRENT USERNAME
break;
};
if (sControlName.indexOf('_')!=-1){ //TEST FOR CONTROL SET MEMBER
var aryControlSet = sControlName.split('_');
if (parseInt(aryControlSet[1])>iRowCount){//*** TRIGGER THE EVENT ***
Logger.log(bExpenseTrigger + ' - ' + !bExpenseTrigger);
chkExpenseAdd.setValue(!bExpenseTrigger, true);
iRowCount = iRowCount +1;
};
};
oControl = app.getElementById(sControlName);
var vCache = cacheSaveReturn(CACHE_UIEX_LISTS,sControlName);
if (typeof vCache == 'undefined'){
oControl.setValue(vControlVal);
oControl.setText(vControlVal);
//controlSetTextBox(oControl,vControlVal);
//controlSetDateBox(oControl,vControlVal);
} else {
if (!(nnGenericFuncLib.arrayIsReal(vCache))){
vCache = JSON.parse(vCache);
};
vCache = vCache.indexOf(vControlVal);
if (vCache != -1){
oControl.setSelectedIndex(vCache);
} else {
controlSetListBox(oControl,vControlVal);
};
};
};
//SOME CODE REMOVED HERE
hideDialog();
return app;
Mogsdad to the rescue!
The answer (see above) for those at the back of the class (with me) is to simply pass the app instance parameter (e) to the event function, calling it directly from the main routine, thus keeping the chronology in step for when it returns the app to complete the routine. No need for the checkbox in this situation.
This only took me all day, but thanks Mogsdad! :)
Snippet below taken from 1/2 way down code sample 2 in the OP:
if (sControlName.indexOf('_')!=-1){ //TEST FOR CONTROL SET MEMBER
var aryControlSet = sControlName.split('_');
if (parseInt(aryControlSet[1])>iRowCount){
eventAddExpense(e); //THAT'S ALL IT TAKES
iRowCount = iRowCount +1;
};
};
I am trying to get the row item values (name, email, age) but I'm only able to get the first item by using the code below.
How can I get other row text by changing tr:eq(1) code or is there any other way to get two items value?
$("#grid_").kendoDropTarget({
drop: function (e) {
var data = grid.dataItem("tr:eq(1)");
// I only get first row but I need to dynamically get any row items.
alert(data.name);
}
});
plz try this..
var entityGrid = $("#DataGrid").data("kendoGrid");
var data = entityGrid.dataSource.data();
var totalNumber = data.length;
for(var i = 0; i<totalNumber; i++) {
var currentDataItem = data[i];
VersionIdArray[i] = currentDataItem.VersionId;
}
Thanks Sanjay however I was looking to just select a row items and this is what I got:
//Selecting Grid
var gview = $("#grid").data("kendoGrid");
//Getting selected item
var selectedItem = gview.dataItem(gview.select());
//accessing selected rows data
alert(selectedItem.email);
So it worked out perfect.
if your grid is set to selectable: true, use the following:
var mygrid = $("#grid").kendoGrid({
selectable: true
});
mygrid.on("click", "tr", function() {
var datarowindex = mygrid.data("kendoGrid").items().index(mygrid.data("kendoGrid").select());
var datarowid = mygrid.data("kendoGrid").dataItem(mygrid.data("kendoGrid").select()).MyId;
alert("index: " + datarowindex + " | value: " + datarowid);
});
if your Kendo UI Grid is set to selectable: false, use the following:
var mygrid = $("#grid").kendoGrid({
selectable: false
});
mygrid.on("click", "tr", function() {
var datarowindex = mygrid.data("kendoGrid").items().index($(this));
var datarowid = mygrid.data("kendoGrid").dataItem($(this).closest("tr")).MyId;
alert("index: " + datarowindex + " | value: " + datarowid);
});
where MyId is the property you are looking for.
I usually use the model from the event. Sometimes, actually very rarely, the row gets deselected and so, the .select() will return a 0 length object which will throw error while trying to access undefined properties.
You might be safer using: e.model.name
I am using a forEach loop that adds movieclips to the stage for each node in my XML. How does one give these movieclips unique instance names as their being added in the loop?
Here is my parseList function which contains the forEach loop mentioned and the syntax I'm using which isn't working for me.
private function parseList():void {
//use Number variables to keep track of current x and y properties as list display is generated
var titleField:TextField = TextField(listItem);
var itemY:Number = 503;
var itemX:Number = 0;
var artistTracker:String = Playmaster_Jukebox.currArtist;
var artID = 0;
var albID = 0;
var itemID:Number=0;
for each (var listItemData:XML in mainXML.artist[artID].album[albID].track) {
var listItem:MovieClip = new ListItem(itemTitle);
listContainer.addChild(listItem);
listItem.name = "itemID" + " " + albID + " " + itemID;
itemID++;
listItem.y = itemY;
listItem.x = itemX;
TextField(listItem.listItemTitleField);
itemY += listItem.height + 10;
}
}
I am a beginner with the forEach loop and don't understand it yet so comments are appreciated!
If I understand your question correctly; then you're asking how to store the "listItem" MovieClips as you read them from the XML document.
To do this you're probably going to want to use either an Array or a Map:
Using an Array ie:
var listItemArray:Array = new Array();
for each (var listItemData:XML in mainXML.artist[artID].album[albID].track) {
var listItem:MovieClip = new ListItem(itemTitle);
listContainer.addChild(listItem);
listItemArray.push(listItem);// adds the item to the array
}
Using a Map ie:
var listItemMap:Object = {};
for each (var listItemData:XML in mainXML.artist[artID].album[albID].track) {
var listItem:MovieClip = new ListItem(itemTitle);
listContainer.addChild(listItem);
listItem.name = "itemID" + " " + albID + " " + itemID;
listItemMap[listItem.name];// adds an item by the .name you created for it.
}
The map will allow you too look up the items by the names you've given the different items. ie: listItemMap["name"] would find the element with named "name".
The array will allow you to loop through them in order. ie: listItemArray[0] would find the first element.
It's up to you to decide which would be better for your purposes.
