Javascript Tricks and Hacks

Question

Hi,

I would like to gather some ideas how you can implement Javascript in a site that don't allow you to put javascript. Site's I'm talking about are community sites like MySpace, That only allows you to put HTMLs.

some of their implementation I've seen is something like this.

<img src="imagesource" onerror="javascript: find head and write external javascript" />

Now I the code being filtered. any ideas on other implementation?

thanks!

Answer 1

If they don't allow JavaScript, they probably don't want you to use JavaScript. I don't think trying to work it around is a good idea.

Answer 2

If you only want this for drop down menus, it will be easier to implement a javascript free approach, such as this one: http://www.tjkdesign.com/articles/Pure%5FCSS%5FDropdown%5FMenus.asp

Basically, you should lean on the :hover css pseudo-class to do the hard work.
