html中最常使用的控件就是div了,那么如何获取div的坐标呢?
如下方法可以实现：
/*** * 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 } }
com.whuang.hsj.divCoordinate()方法介绍
功能:返回div坐标;
参数:div对象或div的id(字符串);
返回值:对象,有六个属性:
width:div自身的宽度;
height:div自身的高度;
x:div左上角的坐标x;
y:div左上角的坐标y;
scrollLeft:水平滚动条的位置
