function GenerateContentList()
{
    var mainContent = $(\'#cnblogs_post_body\');
    var h2_list = $(\'#cnblogs_post_body h4\');//如果你的章节标题不是h2,只需要将这里的h2换掉即可

    if(mainContent.length < 1)
        return;
 
    if(h2_list.length>0)
    {
        var content = \'<a name="_labelTop"></a>\';
        content += \'<div id="navCategory" style="color:#152e97;">\';
        content += \'<p style="font-size:18px;"><b>目录</b></p>\';
        content += \'<ul>\';
        for(var i=0; i<h2_list.length; i++)
        {
            var go_to_top = \'<div style="text-align: right;"><a href="#_labelTop" style="color:#f68a33">回到顶部</a><a name="_label\' + i + \'"></a></div>\';
            $(h2_list[i]).before(go_to_top);
            
            var h3_list = $(h2_list[i]).nextAll("h5");
            var li3_content = \'\';
            for(var j=0; j<h3_list.length; j++)
            {
                var tmp = $(h3_list[j]).prevAll(\'h4\').first();
                if(!tmp.is(h2_list[i]))
                    break;
                var li3_anchor = \'<a name="_label\' + i + \'_\' + j + \'"></a>\';
                $(h3_list[j]).before(li3_anchor);
                li3_content += \'<li><a href="#_label\' + i + \'_\' + j + \'">\' + $(h3_list[j]).text() + \'</a></li>\';
            }
            
            var li2_content = \'\';
            if(li3_content.length > 0)
                li2_content = \'<li><a href="#_label\' + i + \'">\' + $(h2_list[i]).text() + \'</a><ul>\' + li3_content + \'</ul></li>\';
            else
                li2_content = \'<li><a href="#_label\' + i + \'">\' + $(h2_list[i]).text() + \'</a></li>\';
            content += li2_content;
        }
        content += \'</ul>\';
        content += \'</div><p> </p>\';
        content += \'<hr style="height:1px;border:none;border-top:1px dashed #0066CC;"/>\';
        if($(\'#cnblogs_post_body\').length != 0 )
