View Full Version : How to 'check' all checkboxes in the list to 'check' the single checkbox?

8 May 2012, 11:32 PM
Hello friends, I am stuck at a situation in which i have to 'check' all the checkboxes present in the list by 'checking' a checkbox situated in toolbar.

Here's code to create checkbox list:-

itemTpl: '<input type="checkbox" name="box" enabled="enabled" value="open" name="comment_status" id="status" <tpl if="active">checked="checked"</tpl> /> {groupName}{#}',

Here's my checkbox code:-

var checkBox = {
xtype: 'checkboxfield',
name : 'all',
// label: 'All',
itemId: 'all',
value: 'all',
lableWidth: "0",
width: 1,
padding: '0 0 15 30',
checked: false,
listeners: {
check:function() {
// alert("check");

item = Ext.get("status");

chkBox = item.down('input').dom;

var checkboxes = Ext.getStore('group');

for(var i=0;i<checkboxes.getCount();i++){
chkBox.checked = true;

// alert("uncheck");

On the above checkbox check , I want that all the checkboxes defined in "itemTpl" will be checked and vice versa .I know my code inside the check : function(){} is no that good that solve my problem(Both the codes in different views).

So, please advise me some solution of this problem.

Thanx in advance.

I think there's 2 ways to handle this.

1. What you really want to do I'm assuming is to change the stored data so that all of your statuses are active, right?
To do this, change check:function to be

record.set('active', true);
This should cause the dataview to be regenerated and all of the checkboxes will be checked.

2. The other way is somewhat like what you are doing, however, it would appear that you are retrieving the first chkBox and repeatedly checking it instead of iterating through the set of checkboxes.

var items= Ext.DomQuery.query("input[name='comment_status']");//gets an array of all status checkboxes. You can't really use the id attribute because you can't have multiple elements with the same id so your id='status' in the itemTpl is probably causing some problems. You also have 2 name attributes on the checkbox (box and comment_status) so this may not work until you get rid of the box name attribute.

Ext.each(items, function(item){

That should do it. (or be pretty close anyway).
