I am trying to write a web widget which will allow users to display customized information (from my website) in their own web page. The mechanism I want to use (for creating the web widget) is javascript.
So basically, I want to be able to write some javascript code like this (this is what the end user copies into their HTML page, to get my widget displayed in their page)
<script type="text/javascript">
/* javascript here to fetch page from remote url and insert into DOM */
</script>
I have two questions:
how do I write a javascript code to fetch the page from the remote url? Ideally this will be PLAIN javascript (i.e. not using jQuery etc - since I dont want to force the user to get third party scripts jQuery which may conflict with other scripts on their page etc)
The page I am fetching contains inline javascript, which gets executed in an body.onLoad event, as well as other functions which are used in response to user actions - my questions are:
i). will the body.onLoad event be triggered for the retrieved document?.
ii). If the retrieved page is dumped directly into the DOM, then the document will contain two <body> sections, which is no longer valid (X)HTML - however, I need the body.onLoad event to be triggered for the page to be setup correctly, and I also need the other functions in the retrieved page, for the retrieved page to be able to respond to the user interaction.
Any suggestions/tips on how I can solve these problems?
