Defining (embedding) Javascript

Question

I would like to collect all possible ways with which JavaScript can be defined in the web page for execution.

So far I know the basic part:

• script tag
• external script
• element attributes that start with "on"
• inside some tag: WIDTH="&{barWidth};%" ALIGN="LEFT"
• CSS IE: style="left:expression(document.body.clientWidth/2-oDiv.offsetWidth/2);"
• DHTML behavior in IE
• in links: href="javascript:alert('Hi')"

Thanks!

Answer 1

I think the only one left is in the href attribute of anchors links like:

<a href="javascript:alert('hello, world!');">Say Hello</a>

This is how bookmarklets work.

Answer 2

More fugly things:

CSS expressions in IE — allows defining CSS properties as JavaScript expressions, which are evaluated on every possible DOM-event (on every mouse move, scroll step and so on).

DHTML Behaviors in IE — can bind .htc-files with JScript to HTML elements through CSS.

XBL bindings, Mozilla's invention, can be defined via CSS as well.

Answer 3

In links, <a href="javascript:alert('Hi')">
