如何将ajax html响应附加到当前div的旁边

I've DOM如下，

<div id='level-1'>
  <ul>
    <li><span><a>Mike</a></span></li>
    <li><span><a>John</a></span></li>
    <li><span><a>Ket</a></span></li>  
 </ul>
</div>

and jQuery如下，

$(document).on('click','div[id^=[level] ul li span a',function(){

//Making ajax request,no problem in getting the response
// Here I need to append response next to the current div i,e div#level-1 or div#leve-2
});

ajax响应将与上面相同DOM except id of the div和内容anchor tag. id将level-2 or level-3 i,e. +1到 div 的当前值。

Try

$(document).on('click','div[id^=level] ul li span a',function(){
    var parentDiv = $(this).closest("div[id^=level]"); 

    $.ajax(...).done(function(html) {
        parentDiv.after(html);
    });

});
