jquery - 删除元素时出现问题

Question

我不知道为什么会这样:

 $('.deleteQuestion').live('click', function(){
        $.ajax({
            type: 'GET',
            url: '/delete_question/' + $(this).attr('name') + '/',
            success: $('[what="question"][name="' + $(this).attr('name') + '"]').remove()                            
        });      
    });

但这不起作用:

 $('.deleteQuestion').live('click', function(){
        $.ajax({
            type: 'GET',
            url: '/delete_question/' + $(this).attr('name') + '/',
            success: function(){$('[what="question"][name="' + $(this).attr('name') + '"]').remove();}                            }
        });      
    });

有人知道吗？

成功回调不会像点击处理程序一样对 this 进行操作。将其保存在变量中:

$('.deleteQuestion').live('click', function(){
    var element = $(this);
    $.ajax({
         type: 'GET',
         url: '/delete_question/' + $(this).attr('name') + '/',
         success: function(){ //this has to be a function, not a jQuery chain.
              $('[what="question"][name="' + element.attr('name') + '"]').remove();}
         }
    });      
});
