Hi,

Is there any tool that can determine the (x,Y) position of a certain pixel on my screen?

Many thanks,
Xibi

maybe of a certain object, not of a certain pixel. Pixels are measurement units, not objects... So? You need to know the absolute coordinates of an object (the left-top corner)?

Thanks for your help.

I meant a tool that can provide me with the ability to point on a certain pixel in my screen with my mouse, and it will tell me exact (X,Y) coordinate of that pixel.
Otherwise for me (as a not experienced javascripter) positioning is trial and error.

Hope it's clear,
Xibi

Aha, you want to know in fact the position of the mouse measured in pixels. Here's a variant which will show the coordinates of the mouse onclick:

posx=ev.pageX+window.pageXOffset;
posy=ev.pageY+window.pageYOffset;

else if(ev.clientX){//IE
posx=ev.clientX+document.body.scrollLeft;
posy=ev.clientY+document.body.scrollTop;
}
else{return false}//old browsers
document.onclick=function(){
document.getElementById('mydiv').firstChild.data='X='+posx+' Y='+posy;

}

<body onmousemove="getMouse(event)">

I have a question on this, could this be taken a step further an used in conjunction with creating a floating menu that follows along from its top or middle both for horizontally and vertically aligned menus? That would be pretty neato!
