如何将 DOM 对象（输入）传递给 oncomplete 事件的处理程序，以便我可以操作它的父级？

JSF 代码：

<p:datatable>
...
<p:column>

<h:inputText id="my_field" value="#{bean.my_field}">
    <p:ajax oncomplete="handle_oncomplete( $(this) )" listener="#{bean.handle_change}" />
</h:inputText>

</p:column>
...
</p:datatable>

JS代码：

//NOT WORKING
function handle_oncomplete(my_param) {
  _parent = my_param.parent();                 
  _parent.css( "background", "#123456");
}

我使用 my_param.attr('source') 来访问传递的 DOM 对象：

//WORKING
function handle_oncomplete(my_param) {
  _parent = $(my_param.attr('source')).parent();                 
  _parent.css( "background", "#123456");
}

还有其他方法吗？
