obj.style:这个方法只能JS只能获取写在html标签中的写在style属性中的值(style=”…”),而无法获取定义在<style type="text/css">里面的属性。
IE中使用的是obj.currentStyle方法,而FF是用的是getComputedStyle 方法
<style type=”text/css”>
<!–
.ss{color:#cdcdcd;}
–>
</style>
</head>
<body>
<div id=”css88″ class=”ss” style=”width:200px; height:200px; background:#333333″>JS获取CSS属性值</div>
<script type=”text/javascript”>
alert(document.getElementById(“css88″).style.width);//200px
alert(document.getElementById(“css88″).style.color);//空白
</script>
</body>
#myDiv {
background-color:blue;
width:100px;
height:200px;
}
</style>
<body>
<div id ="myDiv" style=" border:1px solid black"></div>
<script>
var myDiv = document.getElementById("myDiv");
var computedStyle = document.defaultView.getComputedStyle(myDiv, null);
alert(computedStyle.backgroundColor); //"red"
alert(computedStyle.width); //"100px"
alert(computedStyle.height); //"200px"
alert(computedStyle.border); //在某些浏览器中是“1px solid black”
</script
<span style="font-family:Arial;font-size:14px;">var myDiv = document.getElementById("myDiv");
var computedStyle = myDiv.currentStyle;
alert(computedStyle.backgroundColor); //"red"
alert(computedStyle.width); //"100px"
alert(computedStyle.height); //"200px"
alert(computedStyle.border); //undefined</span>
style和getComputedStyle(ff)和currentStyle
