var preH = parent.offsetHeight;
var preW = parent.offsetWidth;
var preL = parent.offsetLeft;
var preT = parent.offsetTop;
var mouseOffsetX =0;
var mouseOffsetY =0;
var isDraging = false ;
function resize(dragDiv,handle){
//鼠标按下事件;
//var a =parseInt(handle)
//console.log(a);
var a =handle.splice('')
console.log(a);
handle.onmousedown=function(e){
var e = e;我是设定一个div4角4边共8个点作为事柄handle，但是在后来遇到一个问题，就是这个handle 无法触发事件，用console.log查了下，得到8个数组[div.xxx] xxx是我每个点的classname，请问怎么把handle 转变成可以触发事件的事柄？？我用parseInt打印出来是NAN..求大神帮忙
