How To Select A Checkbox Jquery Object

Why my jquery object didn't get checked with $('.checkall').checked = true ; Here's a Fiddle. UPDATE : working code

Solution 1:

This is a problem of mixing jQuery, and DOM, methods. jQuery doesn't have access to the .value property of the node, instead use:

$('.checkall').prop('checked',true);

Reference:

• prop().

Solution 2:

You need this:

$('.checkall').prop('checked',true);

Or:

$('.checkall')[0].checked = true ;

You would use .prop() to set the property of checked or directly covnert the jQuery element to HTMLElement and then directly set the value.

Solution 3:

Use .prop()

$('.checkall').prop('checked',true)
