如何基于widgetVar在Primefaces组件中查找和/或覆盖JavaScript？ [英] How do I find and/or override JavaScript in Primefaces component based on widgetVar?

问题描述

根据这个问题：使用额外的inputText上传多个文件我可以通过以这种方式使用widgetVar覆盖PrimeFaces元素的JavaScript函数：

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) {
           ...
         }
    });

现在，我尝试覆盖DataTable中的函数，无法理解如何引用它？而且，PF（'）从chrome调试器控制台返回undefined，所以我无法调试它。我怀疑这是范围的问题，但不知道如何解决它。

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.

推荐答案

你可以使用原型，
例如覆盖 bindEditEvents 看起来像这样

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

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