jsf 2 - How do I find and/or override JavaScript in Primefaces component based on widgetVar?

Question

According to this question: Multiple file upload with extra inputText I can override JavaScript function of PrimeFaces element by using widgetVar in this way:

PF('fileUpload').jq.fileupload({
    add: function(e, data) {
           ...
         }
    });

Now, I try to override function in DataTable and can't understand how do I reference to it? Moreover, PF(') returns undefined from chrome debugger console, so I can't debug it. I suspect that it's matter of scopes but don't know how to solve it.

Answer 1

You could use the prototype, for example overriding bindEditEvents would look like this

PrimeFaces.widget.DataTable.prototype.bindEditEvents = function() {
  ....
}
