jquery high Version Select All and select all do not work properly

jquery performs a select-All/no-select operation

<script type= "Text/javascript" >

$ (function () {

$ (' #checkAll '). Click (function () {

$ (': CheckBox '). attr ("Checked", this.checked);

});

})

</script>

But found in 1.10.0 (other versions unknown), the first two can work correctly, but the third time is not. Find the workaround later, use the

$ (': CheckBox '). Prop ("Checked", this.checked);

Alternative

$ (': CheckBox '). attr ("Checked", this.checked);
