In the version of jquery 1.8.x, our operations for selecting and unchecking the checkbox are as follows:

Determine whether to select

Copy code The code is as follows:

$('#checkbox').prop('checked ')

Set checked and unchecked status:

Copy code The code is as follows:

$('#checkbox').attr('checked ',true)
$('#checkbox').attr('checked',false)

But this method is handled differently in jquery1.9.1

In IE10, Chrome, FF, for the selected state, $('#checkbox').attr('checked',true) can be achieved for the first time
But when the selection is cleared through code, the next time it is cleared through code $('#checkbox').attr('checked',true) When selecting
although there is checked='checked' in the code, there is no check in the screen performance.
This problem does not exist under IE8 and IE6.

Later I investigated the relevant information and found that now attr('checked',true) has been replaced by prop('checked',true)
