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>
希望本文所述对大家javascript程序设计有所帮助。
