The properties that get the location of the HTML element are provided in javascript:

Tag: deb title function class off coordinate null get func

Htmlelement.offsetleft
Htmlelement.offsetheight
It should be noted, however, that the values stored by these two properties are not the absolute position of the element relative to the entire browser canvas, but rather the relative position of the position of the parent element, which means that the values are computed in the upper-left corner of the parent element as the (0,0) point. So how do you get an absolute position of an HTML element, using the following function:

The code is as follows:
Get the ordinate of an element
function GetTop (e) {
var offset=e.offsettop;
if (e.offsetparent!=null) offset+=gettop (e.offsetparent);
return offset;
}
Gets the horizontal axis of the element
function GetLeft (e) {
var offset=e.offsetleft;
if (e.offsetparent!=null) offset+=getleft (e.offsetparent);
return offset;
}
