如何在 JSF之前执行 jQuery click() 事件？或执行操作？

尝试使用 jQuery 绑定点击确认（以清理 JSF 页面中的代码）我了解 MyFaces 编写的 onclick 内联函数 (oamSubmitForm();) 在 jQuery click() 事件之前执行。是否可以先执行 jQuery 单击操作？

jQuery(".commandButtonConfirmDelete").click(function() {
  var answer = confirm('Confirm Delete?');
  return answer;
});  

<h:commandLink styleClass="commandButtonConfirmDelete" />
<h:commandButton styleClass="commandButtonConfirmDelete" />

Trying to bind click confirmation with jQuery (to clean code in JSF page) I understand that onclick inline function (oamSubmitForm();) written by MyFaces is executed before jQuery click() event. Is possible to do jQuery click before instead?

jQuery(".commandButtonConfirmDelete").click(function() {
  var answer = confirm('Confirm Delete?');
  return answer;
});  

<h:commandLink styleClass="commandButtonConfirmDelete" />
<h:commandButton styleClass="commandButtonConfirmDelete" />

您最好的选择是检索内联点击事件，保存它，删除它，然后用您自己的函数覆盖它，该函数可以执行您想要执行的操作，并最终调用您删除的已保存函数。我会做这样的事情...

$(function() {
  var node = $('.commandButtonConfirmDelete').get(0),
      savedAction = node.onclick;

  //Remove the inline handler (we'll call it manually in our new handler)
  node.onclick = null;

  $(node).click(function() {
     //do something   

     //then call your inline action
     savedAction();
  });
});

请参阅这个小提琴 - http://jsfiddle.net/C9HTp/1/

alert('bar') 设置为内联，alert('foo') 通过 .click() 绑定。然而，使用上述方法，警报按“foo”然后“bar”的顺序排列。

希望这有帮助！

You're best bet is to retrieve the inline click event, save it, delete it and overwrite it with your own function that does what you want to do and eventually calls the saved function that you deleted. I'd do something like this...

$(function() {
  var node = $('.commandButtonConfirmDelete').get(0),
      savedAction = node.onclick;

  //Remove the inline handler (we'll call it manually in our new handler)
  node.onclick = null;

  $(node).click(function() {
     //do something   

     //then call your inline action
     savedAction();
  });
});

See this fiddle - http://jsfiddle.net/C9HTp/1/

alert('bar') is set inline and alert('foo') is bound via .click(). However using the method described above, the alerts go in order of 'foo' then 'bar'.

Hope this helps!
