From Documentation

ZK framework's Client Engine uses jQuery. It contains a custom jQuery. So you can use jq or $ as a jQuery object like:

$( "div" ).click(function() {

jq(mySelector).css( "background-color" );

You should consider implementing your client code with the bundled jQuery first. For API details, please refer to jQuery Documentation for details.


To obtain the jQuery version bundled with your ZK version enter jq.fn.jquery into Console tab in a developer tool.

Load a Different jQuery

You can load a different version of jQuery by <script/> or <?script?>. Because ZK always load that script later than ZK scripts, the different version of jQuery will override $. Therefore, you can access 2 versions of jquery with different variables:

  • jq to access ZK's bundled jQuery
  • $ to access the different version of jQuery

Please check examples: jquery.zul, jquery2
