1.自动生成目录
(1)页脚JS代码
<script type="text/javascript"> var BlogDirectory = { /* 获取元素位置,距浏览器左边界的距离(left)和距浏览器上边界的距离(top) */ getElementPosition:function (ele) { var topPosition = 0; var leftPosition = 0; while (ele){ topPosition += ele.offsetTop; leftPosition += ele.offsetLeft; ele = ele.offsetParent; } return {top:topPosition, left:leftPosition}; }, /* 获取滚动条当前位置 */ getScrollBarPosition:function () { var scrollBarPosition = document.body.scrollTop || document.documentElement.scrollTop; return scrollBarPosition; }, /* 移动滚动条,finalPos 为目的位置,internal 为移动速度 */ moveScrollBar:function(finalpos, interval) { //若不支持此方法,则退出 if(!window.scrollTo) { return false; } //窗体滚动时,禁用鼠标滚轮 window.onmousewheel = function(){ return false; }; //清除计时 if (document.body.movement) { clearTimeout(document.body.movement); } var currentpos =BlogDirectory.getScrollBarPosition();//获取滚动条当前位置 var dist = 0; if (currentpos == finalpos) {//到达预定位置,则解禁鼠标滚轮,并退出 window.onmousewheel = function(){ return true; } return true; } if (currentpos < finalpos) {//未到达,则计算下一步所要移动的距离 dist = Math.ceil((finalpos - currentpos)/10); currentpos += dist; } if (currentpos > finalpos) { dist = Math.ceil((currentpos - finalpos)/10); currentpos -= dist; } var scrTop = BlogDirectory.getScrollBarPosition();//获取滚动条当前位置 window.scrollTo(0, currentpos);//移动窗口 if(BlogDirectory.getScrollBarPosition() == scrTop)//若已到底部,则解禁鼠标滚轮,并退出 { window.onmousewheel = function(){ return true; } return true; } //进行下一步移动 var repeat = "BlogDirectory.moveScrollBar(" + finalpos + "," + interval + ")"; document.body.movement = setTimeout(repeat, interval); }, htmlDecode:function (text){ var temp = document.createElement("div"); temp.innerHTML = text; var output = temp.innerText || temp.textContent; temp = null; return output; }, /* 创建博客目录, id表示包含博文正文的 div 容器的 id, mt 和 st 分别表示主标题和次级标题的标签名称(如 H2、H3,大写或小写都可以!), interval 表示移动的速度 */ createBlogDirectory:function (id, mt, st, interval){ //获取博文正文div容器 var elem = document.getElementById(id); if(!elem) return false; //获取div中所有元素结点 var nodes = elem.getElementsByTagName("*"); //创建博客目录的div容器 var divSideBar = document.createElement(‘DIV‘); divSideBar.className = ‘uprightsideBar‘; divSideBar.setAttribute(‘id‘, ‘uprightsideBar‘); var divSideBarTab = document.createElement(‘DIV‘); divSideBarTab.setAttribute(‘id‘, ‘sideBarTab‘); divSideBar.appendChild(divSideBarTab); var h2 = document.createElement(‘H2‘); divSideBarTab.appendChild(h2); var txt = document.createTextNode(‘目录导航‘); h2.appendChild(txt); var divSideBarContents = document.createElement(‘DIV‘); divSideBarContents.style.display = ‘none‘; divSideBarContents.setAttribute(‘id‘, ‘sideBarContents‘); divSideBar.appendChild(divSideBarContents); //创建自定义列表 var dlist = document.createElement("dl"); divSideBarContents.appendChild(dlist); var num = 0;//统计找到的mt和st mt = mt.toUpperCase();//转化成大写 st = st.toUpperCase();//转化成大写 //遍历所有元素结点 for(var i=0; i<nodes.length; i++) { if(nodes[i].nodeName == mt|| nodes[i].nodeName == st) { //获取标题文本 var nodetext = nodes[i].innerHTML.replace(/</?[^>]+>/g,"");//innerHTML里面的内容可能有HTML标签,所以用正则表达式去除HTML的标签 nodetext = nodetext.replace(/ /ig, "");//替换掉所有的 nodetext = BlogDirectory.htmlDecode(nodetext); //插入锚 nodes[i].setAttribute("id", "blogTitle" + num); var item; switch(nodes[i].nodeName) { case mt: //若为主标题 item = document.createElement("dt"); break; case st: //若为子标题 item = document.createElement("dd"); break; } //创建锚链接 var itemtext = document.createTextNode(nodetext); item.appendChild(itemtext); item.setAttribute("name", num); item.onclick = function(){ //添加鼠标点击触发函数 var pos = BlogDirectory.getElementPosition(document.getElementById("blogTitle" + this.getAttribute("name"))); if(!BlogDirectory.moveScrollBar(pos.top, interval)) return false; }; //将自定义表项加入自定义列表中 dlist.appendChild(item); num++; } } if(num == 0) 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("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
/*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)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.推荐和反对
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‘; }
6.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/you"><img width="149" height="149" src="https://github.blog/wp-content/uploads/2008/12/forkme_right_orange_ff7600.png?resize=149%2C149" class="attachment-full size-full" alt="Fork me on GitHub" data-recalc-dims="1"></a>
更多 "Fork me on Github" 样式可以在 Github 上获取
7.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); }
