Programmatic Onclick

[johkar]

I need the alternative for the click() method that will work in the
latest FireFox and Netscape browsers. I have found postings like the
one below, but I can't seem to make it work.

http://groups-beta.google.com/group/comp.lang.javascript/browse_thread/thread/27e7c70e51ff8a99?tvc=2&q=onclick+programmatically

I have a tree menu that I store the levels in a cookie, when the user
returns, I read the level values out of the cookie so the tree is in
its' former state. I need to know how to programmaticall y click
document.getEle mentsByTagName( 'LI')[lev1]

Any help or pointers appreciated. - John

//Returns tree to previous state. Cookie only held for browser
session.
function setTreeVals(){
//checks for TreeVals existence
if(document.coo kie.indexOf('Tr eeVals') > -1){
var levels=getSecti on('TreeVals');
var lev1=levels.spl it('|')[0]
var lev2=levels.spl it('|')[1]
var lev3=levels.spl it('|')[2]
var lev4=levels.spl it('|')[3]
//opens tree
if(lev1)
document.getEle mentsByTagName( 'LI')[lev1].click();
if(lev2)
document.getEle mentsByTagName( 'LI')[lev2].click();
if(lev3)
document.getEle mentsByTagName( 'LI')[lev3].click();
if(lev4)
document.getEle mentsByTagName( 'LI')[lev4].click();
}
}

click() or onclick()?

Presumably you have set an onclick event on each <li> that
displays the lower levels. So all you want to do is fire the
appropriate event(s).

As Grant suggested in your referenced post, try:

document.getEle mentsByTagName( 'LI')[lev1].onclick();

Let me clarify, the click() method in IE is the same as if you had
clicked on the object with your mouse. I need to do the same thing
with the latest non IE browsers. The other post in my message referred
to using eventListeners and dispatchEvent, but I couldn't seem to make
that work either. I am still confused on how to appraoch.
