Javascript 如何在jQuery.load（html）之后在jQuery.Treeview中选择当前元素？

我在sample.HTML文件中有这样的HTML代码：

<ul id='topics' class='filetree'>
<li><span class='folder'><a href='?Lang=en&TopicID=#'>Topics</a></span>
<ul>
<li><span class='folder'><a href='?Lang=en&TopicID=1'>Topic 1</a></span>
<ul>
<li><span class='file'><a href='?Lang=en&TopicID=1.1'>Topic 1.1</a></span></li>
<li><span class='file'><a href='?Lang=en&TopicID=1.2'>Topic 1.2</a></span></li>
<li><span class='file'><a href='?Lang=en&TopicID=1.3'>Topic 1.3</a></span></li>
</ul>
</li>

完整的代码如贝娄

<div id="LtrLeftContent">
        <script language="javascript" type="text/javascript">  
            $('#LtrLeftContent').load('sample.html', function () {  
                $("#topics").treeview();  
                $("li span").click(function () {  
                    alert($(this).text());  
                });  
            });                 
        </script>  
</div>  

$（'#LtrLeftContent'）.load（'sample.html'，function（）{
$（“#主题”）.treeview（）；
$（“li span”）。单击（函数（）{
警报（$（this.text（））；
});  
});                 

$("li span").click(function () {
    alert($(this).text());
});

<div id="LtrLeftContent">
        <script language="javascript" type="text/javascript">  
            $('#LtrLeftContent').load('sample.html', function () {  
                $("#topics").treeview();  
                $("li span").click(function () {  
                    alert($(this).text());  
                });  
            });                 
        </script>  
</div>  

$('a').live('click', function (e) {
    e.preventDefault();
    console.log($(e.currentTarget).text());
    console.log($(e.currentTarget).closest('.folder').text());

    // didn't quite get your last question
    // but this is how you would manipulate 
    // the current elements parent list item
    $(e.currentTarget).parents('li').css({
        'background-color': '#000'
    });
    return false;
});
