本文实例讲述了JS判断iframe是否加载完成的方法。分享给大家供大家参考，具体如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title></title>
</head>
<body>
<script type="text/javascript">
var isIE = /msie/i.test(navigator.userAgent) && !window.opera;
var iframe = document.createElement("iframe");
iframe.src = "http://www.jb51.net/";
if (isIE) {
iframe.onreadystatechange = function(){
if(iframe.readyState == "loaded" || iframe.readyState == "complete"){
alert("loaded");
}
};
} else {
iframe.onload = function(){
alert("loaded");
};
}
document.body.appendChild(iframe);
</script>
</body>
</html>
或者
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title></title>
</head>
<body>
<script type="text/javascript">
var iframe = document.createElement("iframe");
iframe.src = "http://www.jb51.net/";
if (iframe.attachEvent){
iframe.attachEvent("onload", function(){
alert("loaded");
});
} else {
iframe.onload = function(){
alert("loaded");
};
}
document.body.appendChild(iframe);
</script>
</body>
</html>
