html中最常使用的控件就是div了,那么如何获取div的坐标呢?
如何方法可以实现.
/***
* 获取div的坐标
* @param divobj
* @returns {{width: number, height: number, left: *, top: window}}
*/
com.whuang.hsj.divcoordinate=function(divobj){
if(typeof divobj == 'string'){
divobj=com.whuang.hsj.$$id('divobj');
}
return {'width':divobj.offsetwidth,'height':divobj.offsetheight,
'x':divobj.offsetleft,'y':divobj.offsettop,
'scrollleft':com.whuang.hsj.getscroll().left,'scrolltop':com.whuang.hsj.getscroll().top};
}
// cross browser gets the position of scroll
com.whuang.hsj.getscroll=function(){
return {
top:document.documentelement.scrolltop || document.body.scrolltop,
left:document.documentelement.scrollleft || document.body.scrollleft
