选项卡,都不陌生,今天把之前的代码翻出来重写了下。不多说了,直接上代码
<script> function Tab(){ this.init.apply(this,arguments); } Tab.prototype = { /* 初始化方法 获取html元素(视图),并绑定事件 */ init:function(){ this.tab = document.getElementById(‘tab‘); this.tabs = tab.getElementsByTagName(‘li‘); this.contents = document.getElementById(‘content‘).getElementsByTagName(‘ul‘); for(var i=0;i<this.tabs.length;i++){ this.tabs[i].index = i; } this.addListener(this.tab,‘click‘,this.bind(this,this.showTab)); }, /* 改变函数func的执行上下文 */ bind:function(obj,func){ return function(e){ func.apply(obj,arguments); } }, /* 通用事件监听方法兼容w3c和IE */ addListener:function(ele,envtype,handler,isBubble){ if(ele.addEventListener){ ele.addEventListener(envtype,handler,isBubble); }else if(ele.attachEvent){ ele.attachEvent("on" + envtype,handler); }else{ ele["on" + enctype] = handler; } }, /* 选项卡的业务逻辑 */ showTab:function(e){ var event = e || window.event; var targetObj = event.target || event.srcElement; if(targetObj.nodeName == ‘LI‘){ for(var i=0;i<this.tabs.length;i++){ this.tabs[i].className = ""; } targetObj.className = ‘current‘; for(var i=0;i<this.contents.length;i++){ this.contents[i].style.display = ‘none‘; } this.contents[targetObj.index].style.display = ‘block‘; } } } window.onload = function(){ new Tab(); } </script>
