$.fn.jqDrag=function(h){return i(this,h,'d');};

$.jqDnR={dnr:{},e:0,
drag:function(v){
if(M.k == 'd')E.css({left:M.X+v.pageX-M.pX,top:M.Y+v.pageY-M.pY});

return false;},
stop:function(){E.css('opacity',M.o);$().unbind('mousemove',J.drag).unbind('mouseup',J.stop);}
};
var J=$.jqDnR,M=J.dnr,E=J.e,
i=function(e,h,k){return e.each(function(){h=(h)？$(h,e):e;
h.bind('mousedown',{e:e,k:k},function(v){var d=v.data,p={};E=d.e;
// attempt utilization of dimensions plugin to fix IE issues
if(E.css('position') != 'relative'){try{E.position(p);}catch(e){}}
M={X:p.left||f('left')||0,Y:p.top||f('top')||0,W:f('width')||E[0].scrollWidth||0,H:f('height')||E[0].scrollHeight||0,pX:v.pageX,pY:v.pageY,k:d.k,o:E.css('opacity')};
E.css({opacity:0.8});$().mousemove($.jqDnR.drag).mouseup($.jqDnR.stop);
return false;
});
});},
f=function(k){return parseInt(E.css(k))||false;};
})(jQuery);
修改后
代码如下：

即可
