Java Menu help...

[linksanime2003]

I don't know anything about JavaScript, but I need to know this.

I have a menu script, but it draws the menu according to pixels. So, if I set the menu to start at 600x10, a user with a resolution lower than that can't use the menu correctly. (I used HTML to take off the scrollbar on the page, so no scrolling.)

Can I add like IF statements and stuff to make it look for screen resolution, then set the start pixels accordingly?

There is a better way then setting your menu at certain point in the screen. What I did for one of my project is lets say a link is what initilizes the drop down. I want the menu to appear right below the link. What you can do is find out the position of the link and display the menu a couple of pixels below it. To to this you need to do some looping to find out exactly where in the page the link is
. Where item is the link. offsetLeft is a property of all objects which tells its offset from the top of its container.

function getWindowOffsetLeft(item)
{
var offset = item.offsetLeft;
var parent = item.offsetParent;

while(parent.tagName!="BODY")
{
offset += parent.offsetLeft;
parent = parent.offsetParent;

}
return offset;
}

function getWindowOffsetTop(item)
{
var offset = item.offsetTop;
var parent = item.offsetParent;

while(parent.tagName!="BODY")
{
offset += parent.offsetTop;
parent = parent.offsetParent;
}

return offset;
}

After you get the offsets, just set your menu.style.left and top equal to the offsets that are returned. Plus a couple more pixels to make it just below it or to the right of it.

Thanks whirlybird540! I've already been given a couple solutions to my problem through other threads, but I am going to try every one to see what works best.
