TypeError: jQuery(…).on is not a function

Question

Guys I have this function from a wordpress plugin:

jQuery( '#widget-twitter-__i__-username' ).on( 'change', function() {
  jQuery('#widget-twitter-__i__-list' ).val(0);
});

jQuery( '#widget-twitter-__i__-list' ).on( 'change', function() {
  jQuery('#widget-twitter-__i__-username' ).val(0);
});

The error I am getting is:

TypeError: jQuery(...).on is not a function

When I click that error on the error console, I get to the above code.

And I was wondering what would be the way to address this issue.

Answer 1

If your jQuery version is under 1.7 i'd suggest using .delegate() or .live() or update your jQuery to the latest version

jQuery( '#widget-twitter-__i__-list' ).delegate(

or

jQuery( '#widget-twitter-__i__-list' ).live(
