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

}; 
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:
