Simple Javascript not working in IE, works in Firefox
The following is a simple piece of code to have javascript open up a soundcloud audio player in a pop-up window. It works perfectly in firefox and chrome, but doesn't work in IE7; it just shows a blank black screen. Does anyone know why?
I get the yellow drop down that says "to help protect.. IE has restricted this webpage from running scripts or ActiveX controls...." Even when I click on it and say allow, the soundcloud player still doesn't appear.

<script type='text/javascript'>
function fetchArguments() {
var arg = window.location.href.split("?")[1].split("&"); // arguments
var len = arg.length; // length of arguments
var obj = {}; // object that maps argument id to argument value
var i; // iterator
var arr; // array
for (var i = 0; i < len; i++) {
arr = arg[i].split("="); // split the argument
obj[arr[0]] = arr[1]; // e.g. obj["song"] = "3"
}
return obj;
}
function loadTitle() {
var args = fetchArguments();
document.title = "Audio: Accidential Seabirds - " + args["name"];
}
function loadMusic() {
var args = fetchArguments();
var height = "100";
object = document.createElement("object");
object.height = height;
object.width = "100%";

The code to call this window might be
function PopupMusic(song, name) {
var ptr = window.open("musicplayer.htm?song="+song+"&name='"+name+"'", song, "resizable='false', HEIGHT=90,WIDTH=600");
if(ptr) ptr.focus();
return false;
}
<a href="javascript:listen()" onclick="javascript:PopupMusic('7537509', 'the appearance of new animals')">Listen</a>
I figured it out. You need to use the setAttributeFunction:
function loadVideo() {
var args = fetchArguments();
var videoFrame = document.createElement("iframe");
videoFrame.setAttribute('id', 'videoFrame');
videoFrame.setAttribute('title', 'YouTube video player');
videoFrame.setAttribute('class', 'youtube-player');
videoFrame.setAttribute('type', 'text/html');
videoFrame.setAttribute('width', args["width"]);
videoFrame.setAttribute('height', args["height"]);
videoFrame.setAttribute('src', 'http://www.youtube.com/embed/' + args["vid"]);
videoFrame.setAttribute('frameborder', '0');
videoFrame.allowFullScreen;
document.getElementsByTagName("body")[0].appendChild(videoFrame); // we append the iframe to the document's body
self.focus();
}
Following code works fine in IE/FF/Chrome:
<script type='text/javascript'>
var musicSrc = 'http://player.soundcloud.com/player.swf?url=http%3A%2F%2Fsoundcloud.com%2Frjchevalier%2Fjust-one-day-ft-deni-hlavinka&color=3b5998&auto_play=true&show_artwork=false';
document.write('<object type="application/x-shockwave-flash" width="100%" height="100%" data="'+musicSrc+'"><param name="movie" value="'+musicSrc+'" /></object>');
</script>
加载中,请稍侯......
