成功后访问$(this):使用$ .ajax时使用function() [英] Accessing $(this) after success:function() when using $.ajax

问题描述

使用jquery后，如何访问$(this)的值:function()?不管我尝试了什么，看来我都做不到.

How can I access the value of $(this) after success: function() when using jquery? No matter what I've tried, it appears I cant do it.

$('.add').click(function() {
//etc etc
    $.ajax({
            type:"GET",
            url:"/",
            data:data,
            dataType: 'json',
            beforeSend:function(html){
                //Nothing here right now
            },
            success: function(){
                $(this).parent("div").after("<div class='flag'>I'm the new one.</div>");
            },

<div id="container">

    <div class="h1" data-id="1">Teachers <span class="add" data-id="US01">Add New</span></span>
    </div>
    <div class="flag">Flag</div>
    <div class="edit">Edit</div>
    <div class="h2" data-id="2">Who is your favorite Math teacher? <span class="add" data-id="US02">Add New</span></div>
    <div class="flag">Flag</div>
    <div class="edit">Edit</div>
        <br>
    <div class="h1" data-id="8">Restaurants <span class="add" data-id="US10">Add New</span></div>
    <div class="flag">Flag</div>
    <div class="edit">Edit</div>
    <div class="h2" data-id="9">Which is your favourtie restaurant in town? <span class="add" data-id="US20">Add New</span></div>
    <div class="flag">Flag</div>
    <div class="edit">Edit</div>

</div>

推荐答案

在进行ajax调用之前将this保存到变量中，并使用该变量:

Save this to a variable before making the ajax call and use that instead:

$('.add').click(function() {
    var self = this; // save this as self
    //etc etc
    $.ajax({
            type:"GET",
            url:"/",
            data:data,
            dataType: 'json',
            beforeSend:function(html){
                //Nothing here right now
            },
            success: function(){
                // use self instead of this
                $(self).parent("div").after("<div class='flag'>I'm the new one.</div>");
            },
