博客园目录生成和页面优化

博客园目录生成和页面优化

一直以为博客园和CSDN不一样，无法生成目录，前两天看到一个人的博客发现有目录，就去网上搜了一下，发现通过脚本可以实现，下面就介绍详细的步骤

一、目录生成

1.1 操作步骤

1、在博客园后台【设置】找到【博客侧边栏公告】，点击右边申请支持JS代码（博主已经申请，所以显示的是支持JS代码）

2、将下面代码复制到【页脚HTML代码】

<script language="javascript" type="text/javascript">
//生成目录索引列表
function GenerateContentList()
{
    var jquery_h1_list = $('#cnblogs_post_body h1');
    if (jquery_h1_list.length == 0) { return; }
    if ($('#cnblogs_post_body').length == 0) { return; }

    var content = '<a name="_labelTop"></a>';
    content    += '<div id="navCategory">';
    content    += '<p style="font-size:18px"><b>阅读目录(Content)</b></p>';
    // 一级目录 start
    content += '<ul class="first_class_ul">';

    for (var i = 0; i < jquery_h1_list.length; i++)
    {
        var go_to_top = '<div style="text-align: right"><a href="#_labelTop">回到顶部(go to top)</a><a name="_label' + i + '"></a></div>';
        $(jquery_h1_list[i]).before(go_to_top);

        // 一级目录的一条
        var li_content = '<li><a href="#_label' + i + '">' + $(jquery_h1_list[i]).text() + '</a></li>';

        var nextH1Index = i + 1;
        if (nextH1Index == jquery_h1_list.length) { nextH1Index = 0; }
        var jquery_h2_list = $(jquery_h1_list[i]).nextUntil(jquery_h1_list[nextH1Index], "h2");
        // 二级目录 start
        if (jquery_h2_list.length > 0)
        {
            //li_content +='<ul style="list-style-type:none; text-align: left; margin:2px 2px;">';
            li_content += '<ul class="second_class_ul">';
        }
        for (var j = 0; j < jquery_h2_list.length; j++)
        {
            var go_to_top2 = '<div style="text-align: right"><a name="_lab2_'+ i + '_' + j + '"></a></div>';
            $(jquery_h2_list[j]).before(go_to_top2);
            // 二级目录的一条
            li_content +='<li><a href="#_lab2_'+ i +'_' + j + '">' + $(jquery_h2_list[j]).text() + '</a></li>';

            var nextH2Index = j + 1;
            var next;
            if (nextH2Index == jquery_h2_list.length) 
            {
                if (i + 1 == jquery_h1_list.length)
                {
                    next = jquery_h1_list[0];
                }
                else
                {
                    next = jquery_h1_list[i + 1];
                }
            }
            else
            {
                next = jquery_h2_list[nextH2Index];
            }
            var jquery_h3_list = $(jquery_h2_list[j]).nextUntil(next, "h3");
            // 三级目录 start
            if (jquery_h3_list.length > 0)
            {
                li_content += '<ul class="third_class_ul">';
            }
            
            for (var k = 0; k < jquery_h3_list.length; k++)
            {
                var go_to_third_Content = '<div style="text-align: right"><a name="_label3_' + i + '_' + j + '_' + k + '"></a></div>';
                $(jquery_h3_list[k]).before(go_to_third_Content);
                // 三级目录的一条
                li_content += '<li><a href="#_label3_' + i + '_' + j + '_' + k + '">' + $(jquery_h3_list[k]).text() + '</a></li>';
            }
            
            if (jquery_h3_list.length > 0)
            {
                li_content += '</ul>';
            }
            li_content += '</li>';
            // 三级目录 end
        }
        if (jquery_h2_list.length > 0)
        {
            li_content +='</ul>';
        }
        li_content +='</li>';
        // 二级目录 end

        content += li_content;
    }
    // 一级目录 end
    content += '</ul>';
    content += '</div>';

    $($('#cnblogs_post_body')[0]).prepend(content);
}

GenerateContentList();
</script>
levels of contents

3、保存，此处只显示三级标题，如有需求，自行修改

1.2 效果

效果如本博客所示。

二、页面优化

2.1 页面定制

将下面代码插入到【页面定制CSS代码】

#cnblogs_post_body
{
    color: black;      
    font: 0.875em/1.5em "微软雅黑" , "PTSans" , "Arial" ,sans-serif;
    font-size: 15px;
}
#cnblogs_post_body h1    {
    text-align:center;
    background: #333366;
    border-radius: 6px 6px 6px 6px;
    box-shadow: 0 0 0 1px #5F5A4B, 1px 1px 6px 1px rgba(10, 10, 0, 0.5);
    color: #FFFFFF;
    font-family: "微软雅黑" , "宋体" , "黑体" ,Arial;
    font-size: 23px;
    font-weight: bold;
    height: 25px;
    line-height: 25px;
    margin: 18px 0 !important;
    padding: 8px 0 5px 5px;

}
#cnblogs_post_body h2    {
    text-align:center;
    background: #006699;
    border-radius: 6px 6px 6px 6px;
    box-shadow: 0 0 0 1px #5F5A4B, 1px 1px 6px 1px rgba(10, 10, 0, 0.5);

    font-weight: bold;
    height: 25px;
    line-height: 25px;
    margin: 18px 0 !important;
    padding: 8px 0 5px 5px;
    text-shadow: 2px 2px 3px #222222;
}
#cnblogs_post_body h3    {
    background: #0099CC;
    border-radius: 6px 6px 6px 6px;
    box-shadow: 0 0 0 1px #5F5A4B, 1px 1px 6px 1px rgba(10, 10, 0, 0.5);

    margin: 18px 0 !important;
    padding: 8px 0 5px 5px;
    text-shadow: 2px 2px 3px #222222;
}

2.2 博客侧边栏公告

将下面代码插入到【博客侧边栏公告】

2.3 页首定制

将下面代码插入到【页首HTML】

<link  type="text/css" rel="stylesheet" href="https://files.cnblogs.com/files/miangao/maodian.css">
<script src="https://files.cnblogs.com/files/miangao/maodian.js"></script>
