javascript - Avoid triggering multiple click events -

-

i'm trying make input field disabled/enabled when click on sibling link.

here code.

$('a').on('click',function(){     var inp=$(this).siblings('input');     inp.prop('disabled', false);     $(this).click(function(){         inp.prop('disabled', true);     }); });

when click first time works fine, next time won't work. because both click functions, triggers. i'm unable overcome issue. please me.

see fiddle.

just negate disabled prop on every click. elem.disabled = ! elem.disabled.

demo fiddle: http://jsfiddle.net/abhitalks/2a2ajbnb/1/

snippet:

$('a').on('click',function(){      var $inp = $(this).siblings('input');      $inp.prop('disabled', !$inp.prop('disabled'));  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="text" name="x" value="22" disabled/><a href="#">change</a>
