javascript - 我可以使用它来引用委托(delegate)元素的选择器吗？

Question

例如:

$('#enquiry-form').on('click','.close', function(){ 
    $(this)..code..
});

$(this) 会引用 '.close' 但有没有办法引用 $('#enquiry-form')以类似于使用 javascript 的 this 或 $(this)?

的方式

Answer 1

您可以使用 event.delegateTarget获取委托(delegate)目标。

Live Demo

$('#enquiry-form').on('click','.close', function(event){ 
     alert($(event.delegateTarget)[0].id);
});

This property is most often useful in delegated events attached by .delegate() or .on(), where the event handler is attached at an ancestor of the element being processed. It can be used, for example, to identify and remove event handlers at the delegation point, jQuery Doc.
