0.修改前准备

（1）在后台申请JS权限

（2）选择darkgreentrip主题

1.自动生成目录

（1）页脚JS代码

<script type="text/javascript">

                    var pos = BlogDirectory.getElementPosition(document.getElementById("blogTitle" + this.getAttribute("name")));
                    if(!BlogDirectory.moveScrollBar(pos.top, interval)) return false;
                };

        /*鼠标进入时的事件处理*/
        divSideBarTab.onmouseenter = function(){
            divSideBarContents.style.display = \'block\';
        }
        /*鼠标离开时的事件处理*/
        divSideBar.onmouseleave = function() {
            divSideBarContents.style.display = \'none\';
        }

        document.body.appendChild(divSideBar);
    }
    
};

window.onload=function(){
    /*页面加载完成之后生成博客目录*/
    BlogDirectory.createBlogDirectory("cnblogs_post_body","h2","h3",20);
}
</script>

（2）页面定制CSS代码

/*生成博客目录的CSS*/
#uprightsideBar{
    font-size:14px;
    font-family:Arial, Helvetica, sans-serif;
    text-align:left;
    position:fixed;/*将div的位置固定到距离top:50px，right:0px的位置，这样div就会处在最右边的位置，距离顶部50px*/
    top:400px;
    right:53px;
    width: auto;
    height: auto; 
    
    
}
#sideBarTab{
    float:left;
    width:30px; 
    border:1px solid #e5e5e5;
    border-right:none;
    text-align:center;
    background:rgb(238, 130, 238);
}

#sideBarContents{
    float:left;
    overflow:auto; 
    overflow-x:hidden;!important;
    width:200px;
    min-height:108px;
    max-height:460px;
    border:1px solid #e5e5e5;
    border-right:none; 
    background:#ffffff;
}
#sideBarContents dl{
    margin:0;
    padding:0;
}

#sideBarContents dt{
    margin-top:5px;
    margin-left:5px;
}

#sideBarContents dd, dt {
    cursor: pointer;
}

#sideBarContents dd:hover, dt:hover {
    color:#A7995A;
}
#sideBarContents dd{
    margin-left:20px;
}

2.增加返回顶部按钮

（1）定制CSS代码

/* 返回顶部按钮 */
#back-to-top {
    background-color: #00CD00;
    bottom: 0;
    box-shadow: 0 0 6px #00CD00;
    color: #444444;
    padding: 10px 10px;
    position: fixed;
    right: 20px;
    cursor: pointer;
}

（2）页首HTML代码

<span id="back-to-top"><a href="#top">返回顶部</a></span>

3.爱心特效

将以下代码复制到公告栏：

<!-- 爱心特效 -->
<script type="text/javascript">
(function(window,document,undefined){
        var hearts = [];
        window.requestAnimationFrame = (function(){
                return window.requestAnimationFrame || 
                           window.webkitRequestAnimationFrame ||
                           window.mozRequestAnimationFrame ||
                           window.oRequestAnimationFrame ||
                           window.msRequestAnimationFrame ||
                           function (callback){
                                   setTimeout(callback,1000/60);
                           }
        })();
        init();
        function init(){
                css(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: \'\';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: absolute;}.heart:after{top: -5px;}.heart:before{left: -5px;}");
                attachEvent();
                gameloop();
        }
        function gameloop(){
                for(var i=0;i<hearts.length;i++){
                    if(hearts[i].alpha <=0){
                            document.body.removeChild(hearts[i].el);
                            hearts.splice(i,1);
                            continue;
                    }
                    hearts[i].y--;
                    hearts[i].scale += 0.004;
                    hearts[i].alpha -= 0.013;
                    hearts[i].el.style.cssText = "left:"+hearts[i].x+"px;top:"+hearts[i].y+"px;opacity:"+hearts[i].alpha+";transform:scale("+hearts[i].scale+","+hearts[i].scale+") rotate(45deg);background:"+hearts[i].color;
            }
            requestAnimationFrame(gameloop);
        }
        function attachEvent(){
                var old = typeof window.onclick==="function" && window.onclick;
                window.onclick = function(event){
                        old && old();
                        createHeart(event);
                }
        }
        function createHeart(event){
            var d = document.createElement("div");
            d.className = "heart";
            hearts.push({
                    el : d,
                    x : event.clientX - 5,
                    y : event.clientY - 5,
                    scale : 1,
                    alpha : 1,
                    color : randomColor()
            });
            document.body.appendChild(d);
    }
    function css(css){
            var style = document.createElement("style");
                style.type="text/css";
                try{
                    style.appendChild(document.createTextNode(css));
                }catch(ex){
                    style.styleSheet.cssText = css;
                }
                document.getElementsByTagName(\'head\')[0].appendChild(style);
    }
        function randomColor(){
                return "rgb("+(~~(Math.random()*255))+","+(~~(Math.random()*255))+","+(~~(Math.random()*255))+")";
        }
})(window,document);
</script>

4.设置签名格式

页面定制CSS代码

/* 设置签名格式 */
#MySignature {
    display: none;
    background-color: #B2E866;
    border-radius: 10px;
    box-shadow: 1px 1px 1px #6B6B6B;
    padding: 10px;
    line-height: 1.5;
    text-shadow: 1px 1px 1px #FFF;
    font-size: 16px;
    font-family: \'Microsoft Yahei\';
}

5.添加GitHub图标

页首HTML代码，注意将a标签中的地址替换为自己的GitHub地址

<a href="https://github.com/tester-wu/" title="我的github地址" target="_Blank" class="github-corner" aria-label="View source on Github"><svg width="80" height="80" viewBox="0 0 250 250" style="fill:#FD6C6C; color:#fff; position: absolute; top: 0; border: 0; right: 0;" aria-hidden="true"><path d="M0,0 L115,115 L130,115 L142,142 L250,250 L250,0 Z"></path><path d="M128.3,109.0 C113.8,99.7 119.0,89.6 119.0,89.6 C122.0,82.7 120.5,78.6 120.5,78.6 C119.2,72.0 123.4,76.3 123.4,76.3 C127.3,80.9 125.5,87.3 125.5,87.3 C122.9,97.6 130.6,101.9 134.4,103.2" fill="currentColor" style="transform-origin: 130px 106px;" class="octo-arm"></path><path d="M115.0,115.0 C114.9,115.1 118.7,116.5 119.8,115.4 L133.7,101.6 C136.9,99.2 139.9,98.4 142.2,98.6 C133.8,88.0 127.5,74.4 143.8,58.0 C148.5,53.4 154.0,51.2 159.7,51.0 C160.3,49.4 163.2,43.6 171.4,40.1 C171.4,40.1 176.1,42.5 178.8,56.2 C183.1,58.6 187.2,61.8 190.9,65.4 C194.5,69.0 197.7,73.2 200.1,77.6 C213.8,80.2 216.3,84.9 216.3,84.9 C212.7,93.1 206.9,96.0 205.4,96.6 C205.1,102.4 203.0,107.8 198.3,112.5 C181.9,128.9 168.3,122.5 157.7,114.1 C157.9,116.9 156.7,120.9 152.7,124.9 L141.0,136.5 C139.8,137.7 141.6,141.9 141.8,141.8 Z" fill="currentColor" class="octo-body"></path></svg></a><style>.github-corner:hover .octo-arm{animation:octocat-wave 560ms ease-in-out}@keyframes octocat-wave{0%,100%{transform:rotate(0)}20%,60%{transform:rotate(-25deg)}40%,80%{transform:rotate(10deg)}}@media (max-width:500px){.github-corner:hover .octo-arm{animation:none}.github-corner .octo-arm{animation:octocat-wave 560ms ease-in-out}}</style>

6.评论头像

页脚JS代码

$(".blog_comment_body").before("<div class=\'author-avator\' style=\'float: left;\'><a target=\'_blank\'><img  /></a></div>");
var feedbackCon = $(".feedbackCon");
for (var i = 0; i < feedbackCon.length; i++) {
    var span = $(feedbackCon[i]).find("span:last").eq(0).html()||"http://pic.cnitblog.com/face/sample_face.gif";
    $(feedbackCon[i]).find(".author-avator img").attr("src", span);
    var href = $(feedbackCon[i]).parent().find(".comment_date").next().attr("href");
    $(feedbackCon[i]).find(".author-avator a").attr("href", href);
}
