复制代码 代码如下:
_MoveObj = null;//全部变量，用来表示当前div
z_index = 0;//z方向
jQuery.fn.myDrag=function(){
_IsMove = 0; //是否移动 1.移动
_MouseLeft = 0; //div left坐标
_MouseTop = 0; //div top坐标
$(document).bind("mousemove",function(e){
if(_IsMove==1){
$(_MoveObj).offset({top:e.pageY-_MouseLeft,left:e.pageX-_MouseTop});
}
}).bind("mouseup",function(){
_IsMove=0;
$(_MoveObj).removeClass("downMouse");
});
return $(this).bind("mousedown",function(e){
_IsMove=1;
_MoveObj = this;
var offset =$(this).offset();
_MouseLeft = e.pageX - offset.left;
_MouseTop = e.pageY - offset.top;
z_index++;
_MoveObj.style.zIndex=z_index;
$(_MoveObj).addClass("downMouse");
});
}
