Question

我有代码：

var c_iframe = document.createElement('iframe');
c_iframe.setAttribute('src', 'my_domain_and_url');
if (c_iframe.readyState) {
   c_iframe.onreadystatechange = function () { // for old version of IE
   if (this.readyState == 'complete' || this.readyState == 'loaded') {
        resize();
      }
   };
} else { // other browsers
    c_iframe.onload = resize;
}

此代码适用于IE边缘，但对于IE10和IE9，我正在

SCRIPT16389: Unknown error.

这一行：

if (c_iframe.readyState) {

我做错了什么，我需要什么？

好的，我修好了：

var div = document.createElement("div");
div.innerHTML = "<!--[if lt IE 11]><i></i><![endif]-->";
var isIeLessThan11 = (div.getElementsByTagName("i").length == 1);
if (isIeLessThan11) {
    quiz_iframe.onreadystatechange = function () { // for old version of IE
         if (this.readyState == 'complete' || this.readyState == 'loaded') {
              resize();
         }
    };
 } else { // other browsers
    quiz_iframe.onload = resize;
 }

c_iframe.readyState只是未定义..

IE9 / IE10中的readyState“未知错误”..
