Checkbox all selected-cancel-all selected again no display problem, checkbox all selected

Checkbox all selected-cancel-all selected again no display problem, checkbox all selected

Source code:

<Input type = "checkbox" id = "cleckAll"/> select all

<Div class = "list">

<Input type = "checkbox"/> check box

<Input type = "checkbox"/> check box 2

<Input type = "checkbox"/> check three.

</Div>

 

Script:

$ ('# CleckAll'). click (function (){

If ($ (this). is (': checked ')){

$ ('. List input'). prop ('checked', true );

} Else {

$ ('. List input'). prop ('checked', false );

}

})

 

Note: If you use prop (), do not use attr (). Otherwise, you will be confused...

Solution: the problem is caused by the jQuery version, so I will not explain it again...
