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
}
}
?
