我如何获取jQuery Ajax成功回调中的“ clicked”元素

Question

This is one easy (I hope) question which is bugging me for years. How do you get element that fired event which triggered the ajax request? Here is an example:

<button id="clickme">Click me</button>
$("#clickme").click(function(e){
    var i_need_this=e.target;
    alert(i_need_this); //nice!
    $.ajax({
            url:'http://echo.jsontest.com/',

            type: 'GET',
            success: function( data, status, jqXHR  ) {
                alert('success');
              //console.log( ??? ); Get i_need_this from somewhere?       
            }
        });

})

You can use context param here:

$.ajax({
        url:'http://echo.jsontest.com/',
        context:this, // <------this is the cliked button
        type: 'GET',
