js拖动

var Obj;
var oMove;
function MouseDown(obj){
Obj=obj;
oMove=Obj;
Obj.setCapture();
Obj.l=event.x-oMove.style.pixelLeft;
Obj.t=event.y-oMove.style.pixelTop;
}
function MouseMove(){
if(Obj!=null){
    oMove.style.left = event.x-Obj.l;
    oMove.style.top = event.y-Obj.t;
    }
}
function MouseUp(){

if(Obj!=null){

    Obj.releaseCapture();
   
Obj.style.display=""  //先隐藏

if(document.elementFromPoint(event.x,event.y).id=="c"){  //后获取鼠标坐标对应的对象
     var typeId = document.elementFromPoint(event.x,event.y).lang;
     var cuId = Obj.lang;
     if(window.confirm('你确定要修改群组吗？'))
     window.location.href = '${pageContext.request.contextPath}/customer/customers.do?method=updateType&typeId='+typeId+'&cuId='+cuId+'&c_id=<%=c_id%>&type=cus';
<%--alert(document.elementFromPoint(event.x,event.y).lang);--%>
<%--alert(Obj.lang);--%>
}
Obj.style.display=""  //后显示
    Obj=null;
}
}

调用
<span style="cursor:move" onmousedown="MouseDown(this)" onmousemove="MouseMove()" onmouseup="MouseUp()"  lang="${c[1].cuId}" id="c_name">${c[1].cuName }</span>
