html代码:
<body> <div id="div1"></div> </body>
css代码:
<style type="text/css"> #div1{width:100px;height: 100px;} </style>
js代码:
<script type="text/javascript"> window.onload=function(){ function getStyle(obj,name){ if(obj.currentStyle){ return obj.currentStyle[name]; }else{ return getComputedStyle(obj,false)[name]; } } var oDiv=document.getElementById("div1"); alert(getStyle(oDiv,"width")); } </script>
取行间样式的js代码:
window.onload=function(){ function css(obj,name,value){ if(arguments.length==2){ //两个参数的时候是获取样式 return obj.style[name]; }else{ //三个参数 obj.style[name]=value; } } var oDiv=document.getElementById("div1"); alert(css(oDiv,"width")); }
