I'm having some trouble trying to get a fairly simple popupper to work. The idea is that the parent should open a popup window and then append a div in it.
The relevant parts of the code:
parent.html:
var childWindow;
function togglePref() {
childWindow = window.open("popup.html", "prefPopup", "width=200,height=320");
}
function loadPopupElements() {
var prefElements = document.getElementById("prefBrd").cloneNode(true);
var childDoc = childWindow.document;
var childLink = document.createElement("link");
childLink.setAttribute("href", "pop.css");
childLink.setAttribute("rel", "stylesheet");
childLink.setAttribute("type", "text/css");
childDoc.head.appendChild(childLink);
childDoc.body.appendChild(prefElements);
}
popup.html:
<head>
</head>
<body onload="opener.loadPopupElements();">
</body>
This works fine with Safari and Chrome, but for some reason IE refuses to append anything.
Ok, I managed to work around the problem with a uglyish solution using innerHTML. Apparently, as Hemlock mentioned, IE doesn't support appending children from a another document. Some suggested to take a look at the importNode() method but I seemed to have no luck with it either.
So, the workaround goes as follows:
parent.html:
var childWindow;
function togglePref() {
childWindow = window.open("popup.html", "prefPopup", "width=200,height=320");
}
function loadPopupElements() {
var prefElements = document.getElementById("prefBrd");
var childDoc = childWindow.document;
childDoc.body.innerHTML = prefElements.innerHTML;
}
popup.html:
<head>
<link href="pop.css" rel="stylesheet" type="text/css">
</head>
<body onload="loadElements();">
</body>
<script type="text/javascript">
function loadElements() {
opener.loadPopupElements();
}
</script>
This seems quite a nasty way to go because in my case the #prefBrd contains some input elements with dynamically set values, so in order for the popup.html to grab them, it has to do a bit of iteration at the end of the loadElements() function, which wouldn't have been necessary using appendChild.
