Question

In a HTML/Javascript webpage, the javascript file takes the body of the html, renders the contents in the tag in Flash, and displays the flash content. The page is not flash, it is still Html, but the javascript must be modifying it to display it in Flash. What i want to know is what functions/methods does Javascript use to modify the Html page it is a part of? I know of one – document.write(). Are there any others?

P.S – The javascript file contains about 600 lines of code, so its difficult to analyse each line. Also im kind of a JS newbie.

Flash can be inserted using different methods. SWFObject is one of the popular ones.

If it is not using libraries like SWFObject or jQuery, look for things like createElement, appendChild, getElementById, innerHTML etc.

var obj = document.createElement("embed");
obj.appendChild(necessary_children_to_embed_flash);
document.body.appendChild(obj);

//or
element = document.getElementById("elements_id");
element.innerHTML = "<p>A paragraph</p>followed by html to insert flash";
