jquery - disabling click function on parent elemen

2020-08-23 06:51发布

问题:

i have structure like this

<table><tr><td></td><td><input type="button" name="button"></td></tr></table>
<script> 
$('tr').click(function(){window.alert('tr');})
$(':input').click(function(){window.alert('input');})
</script>

when i click on the button, tr click event also called. is there any way to disable click event on parent element? the only solution i found is to add class to parent element and inside its click function check for it. for example:

 <script> 
$('tr').click(function(){ if(!$(this).hasClass('disable')) { window.alert('tr');  }  $(this).removeClass('disable');  })
$(':input').click(function(){window.alert('input'); $(this).closest('tr').addClass('disable');})
</script>

回答1:

use .stopPropagation()

$('tr').click(function(){
   window.alert('tr');
});
$(':input').click(function(e){
   e.stopPropagation();
   window.alert('input');
});

demo



回答2:

.stopPropagation() would work but if you don't want to stop the entire event then you can just fire it if the targets match.

See this thread.



回答3:

Stop Propagation?

http://api.jquery.com/event.stopPropagation/

This will prevent the click event from bubbling through its parents.



回答4:

You also can check the propagation status using event.stopimmediatepropagation() and event.isImmediatePropagationStopped()

$(':input').click(function(e){
    e.stopImmediatePropagation();
    var status = e.isImmediatePropagationStopped();

    //CHECK
    console.log(status); //true-false
});
