那些年，哥私藏的源代码

1.英文截断

 p{height: 24px;overflow: hidden;width: 100%;word-wrap:break-word;word-break:break-all;}

2.css reset

/*reset*/html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, pre, a, code, del, em, img, strong, sub, sup, b, u, i, dl, dt, dd, ol, ul, li, fieldset, form, label, table, tbody, tfoot, thead, tr, th, td{ margin:0; padding:0; border:0; outline:0; font-size: 100%; vertical-align: baseline; }table { border-collapse:collapse; border-spacing:0px; }ol, ul {list-style:none;}th,td{vertical-align:middle;}

3.clearfix 清除浮动

.clearfix:after{content:'.';display:block;height:0;clear:both;overflow:hidden;}.clearfix{*zoom:1;}

4.body default

body {margin:0px auto; font-family:"宋体",Arial,Helvetica,sans-serif; font-size:12px;background:#f0f1f1;}html,html body{_background-image:url(about:blank);_background-attachment:fixed;}

5.a样式

a{ text-decoration:none; color:#333333; }a:hover{color:#E53434 !important; text-decoration:underline;}a:hover img{text-decoration:none;}

6.来个css整套的（www.meilele.com 版权所有）

/*reset*/html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, pre, a, code, del, em, img, strong, sub, sup, b, u, i, dl, dt, dd, ol, ul, li, fieldset, form, label, table, tbody, tfoot, thead, tr, th, td{ margin:0; padding:0; border:0; outline:0; font-size: 100%; vertical-align: baseline; }table { border-collapse:collapse; border-spacing:0px; }ol, ul {list-style:none;}th,td{vertical-align:middle;}/*common*/.Left { float:left; }.Right { float:right; }.r{text-align:right!important;}.c{text-align:center!important;}.l{text-align:left!important;}a{ text-decoration:none; color:#333333; }.red, a.red { color:#e53434; }.gray, a.gray { color:#787878; }.orange, a.orange { color:#F60; }.black, a.black { color:#333; }.white,a.white{ color:#FFF;}.scarlet,a.scarlet{ color:#E53434;}a:hover{color:#E53434 !important; text-decoration:underline;}a:hover img{text-decoration:none;}.none{ display:none;}.clearfix:after{content:'.';display:block;height:0;clear:both;overflow:hidden;}.clearfix{*zoom:1;}.clear{clear:both }.center{text-align:center;}.w{width:980px; margin-left:auto;margin-right:auto;}.height5 { height:5px; line-height:1px; }.height10 { height:10px; line-height:1px; }.height15 { height:15px; }.height20 { height:20px; }.height25 { height:25px; }.height30 { height:30px; }.height40 { height:40px; }.mt10{margin-top:10px;}.mt15{margin-top:15px;}.mb10{margin-bottom:10px;}.mt20{margin-top:20px;}.inline_block { display:inline-block; }.bold { font-weight:bold; }.f14 { font-size:14px; }.f16 { font-size:16px; }.fline { text-decoration:line-through }.uline{ text-decoration:underline;}.yen{font-family:Arial;}.pointer { cursor:pointer; }.MLL_lazy{ border:none; color:#FFF; background:url(../zxwimg20121022/ajax-loader.gif) center center no-repeat; overflow:hidden; border:1px solid #999; padding:0px; line-height:1px; font-size:1px;}.indent{ text-indent:-9999px; overflow:hidden;}.w970{width:970px; margin-left:auto;margin-right:auto;}img{background:#eee;overflow:hidden;vertical-align:top;}.yahei{font-family: 'Microsoft YaHei',微软雅黑}body {margin:0px auto; font-family:"宋体",Arial,Helvetica,sans-serif; font-size:12px;background:#f0f1f1;}html,html body{_background-image:url(about:blank);_background-attachment:fixed;}

7.操作cookie

/*** 设置cookie* @param {string} name key* @param {string} value value* @param {string/number} Days 有效期，或者'session'* @param {string} domain 作用域。默认meilele.com*/setCookie : function (name, value, Days, domain ,path) {Days = Days || 360;path = path || '/';domain = domain?";domain="+domain:";domain=meilele.com";var expDay = new Date();expDay.setTime(expDay.getTime() + parseInt(Days) * 24 * 60 * 60 * 1000);document.cookie = name + "=" + encodeURIComponent(value) + (Days == "session" ? "" : ";expires=" + expDay.toGMTString()) + domain + ";path="+path;},/* * 获取cookie * @param {string} name key * @return {string} cookie值*/getCookie : function (name) {var cookieValue;if (document.cookie && document.cookie != '') {var cookies = document.cookie.split(';');var cookieLength = cookies.length;for (var i = 0; i < cookieLength; i++) {var cookie = cookies[i].replace(/(^\s*)|(\s*$)/g, "");if (cookie.substring(0, name.length + 1) == (name + '=')) {cookieValue = decodeURIComponent(cookie.substring(name.length + 1));break;}}}return cookieValue;},

8，设置为首页，加入收藏

/* * @设为首页*/setHome : function(){var url = window.location.href;try {obj.style.behavior = 'url(#default#homepage)';obj.setHomePage(url);}catch(e) {if (window.netscape) {try {netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");}catch(e) {alert("此操作被浏览器拒绝！\n请在浏览器地址栏输入“about:config”并回车\n然后将 [signed.applets.codebase_principal_support]的值设置为'true',双击即可。");}var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);prefs.setCharPref('browser.startup.homepage', url);}}},/* * @加入收藏*/addFavorites : function(){var sURL=window.location.href;var sTitle=document.title;try{window.external.addFavorite(sURL,sTitle);}catch(e){try{window.sidebar.addPanel(sTitle,sURL,"");}catch(e){alert("加入收藏失败，请使用Ctrl+D进行添加");}}},

9.将json格式数据转为字符串

//将json格式数据转化为字符串jsonToString: function( json ) {var strTemp = [];if ( typeof json != "object" ) {return;}for ( var k in json ) {strTemp.push( '\"' + k + '\":' + '\"' + json[k] + '\"' );}return "{" + strTemp.join(",") + "}";},

10.设置透明度

/* * @设置透明度 * @param: target {objext} 目标对象 * @param: value {number} 透明度值*/setOpacity : function( target, value ){if( document.documentElement.filters ){target.style.filter = "alpha(opacity="+value+")";}else{target.style.opacity = value/100;}},

11.元素距离顶部偏移量

offsetTop:function (obj) {var offsetParent = obj;if(!obj)return 0;var top = 0;while (offsetParent != null && offsetParent != document.body) {top += offsetParent.offsetTop;offsetParent = offsetParent.offsetParent;}return top;},

12.取消事件默认行为

if ( e && e.preventDefault ){ e.preventDefault();} else { window.event.returnValue = false;} 

13.阻止事件冒泡

          function stopPP(e)      {           var evt = e|| window.event;           //IE用cancelBubble=true来阻止而FF下需要用stopPropagation方法           evt.stopPropagation ?evt.stopPropagation() : (evt.cancelBubble=true);      }

14.clearfix

/*clearfix*/.clearfix:before, .clearfix:after {display: table;line-height: 0;content: "";}.clearfix:after {clear: both;}.clearfix:after {content: ".";display: block;height: 0;clear: both;visibility: hidden;}.clearfix {*zoom:1;}

15.img hover

/*img hover*/img:hover {opacity: 0.85;}img {-ms-interpolation-mode: bicubic;/*ie7 专用，消除图片锯齿*/-webkit-transition: all 200ms ease-in;-moz-transition: all 200ms ease-in;-o-transition: all 200ms ease-in;transition: all 200ms ease-in;}

16,jquery 同步控制

$.ajaxSetup({     async : false });    $.ajaxSetup({    async : true  });
