IE下操作IFrame内容的代码:
document.frames["MyIFrame"].document.getElementById("s").style.color="blue";
但是这在Firefox下无效。
所以，想到在Firefox下用FireBug来调试。经过调试发现在Firefox下可用以下代码来实现:
document.getElementById("MyIFrame").contentDocument.getElementById("s").style.color="blue";
详细代码如下:
TestIFrame.htm:
<html>
<head>
<script type="text/javascript">
function f(){
var doc;
if (document.all){//IE
doc = document.frames["MyIFrame"].document;
}else{//Firefox
doc = document.getElementById("MyIFrame").contentDocument;
}
doc.getElementById("s").style.color="blue";
}
</script>
</head>
<body onload="f()">
<iframe id = "MyIFrame" name = "MyIFrame" src = "MyIFrame.htm" width = "100" height="100">
</body>
</html>
