得到父母 <li> 使用jQuery的项目

Question

I am trying to get the parent <li> when I click on a specific <li> item.

http://jsfiddle.net/doonot/GjbZk/

So let's say I click on submodule 1 , I get the clicked ID with $(this).attr('id'); How can I now get the ID of the parent <li> which is in this case module 1 ?

Please note that my tree is quite big, so it has to be flexible.

Thanks a lot, much appreciate your answer.

Answer 1

You can use the closest method to get the first ancestor that matches a selector:

var li = $(this).closest("li");

From the jQuery docs:

Get the first element that matches the selector, beginning at the current element and progressing up through the DOM tree.

Answer 2

var parentModule = $('this')             //the selector of your span
    .parents('li:eq(1)')                 //get the next li parent, not the direct li
    .children('.rightclickarea:first')   //get the first element, which would be the span
    .attr('id')                          //get the span id

Answer 3

var parent = $(this).closest("li");
