var iframe = document.createElement("iframe"); 
iframe.src = "//www.VeVB.COm"; 

if (!/*@cc_on!@*/0) { //if not IE 
iframe.onload = function(){ 
alert("Local iframe is now loaded."); 
}; 
} else { 
iframe.onreadystatechange = function(){ 
if (iframe.readyState == "complete"){ 
alert("Local iframe is now loaded."); 
} 
}; 
} 
document.body.appendChild(iframe);

最近， Nicholas C. Zakas 文章《Iframes, onload, and document.domain》的评论中 Christopher 提供了一个新的判断方法（很完美）：

复制代码代码如下:

var iframe = document.createElement("iframe"); 
iframe.src = "//www.VeVB.COm"; 

if (iframe.attachEvent){ 
iframe.attachEvent("onload", function(){ 
alert("Local iframe is now loaded."); 
}); 
} else { 
iframe.onload = function(){ 
alert("Local iframe is now loaded."); 
}; 
} 

document.body.appendChild(iframe);
