Js代码

- * @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
- }
- }
