I am writing a plugin to an old IE-only WYSIWYG-editor which resides in an old CMS. I've created a plugin that opens an popup where the user kan enter the url of an youtube clip.

The popup then creates the corrent <object..><param..> markup for the embed and uses Internet Explorers pasteHTML function;

var range = plugin.editorDocument.selection.createRange();
var embedHtml = OpenDialog(dialogUrl, null, 400, 200);

if (!embedHtml) {
    return;
}
range.pasteHTML(embedHtml);

I know it's missing a bit of information about some of the variables but you get the picture. The problem is that the <param>-tags gets removed when i run the pasteHTML. I wonder if anyone have an idea of fixing this, and letting me keep my param-tags
