want make a marquee that only on mouse over works

some things like this :

<marquee  onload="this.stop()" onmouseout="this.stop()" onmouseover="this.start()">string</marquee>

but it does not have onload event I dont want (can not) use body events (I can edit only one part of page that contain some dive and this marquee)

how can I make it stop on start of page without using onload of body
