修改后
(function($){ $.fn.jqDrag=function(h){return i(this,h,'d');}; $.fn.jqResize=function(h){return i(this,h,'r');}; $.jqDnR={dnr:{},e:0, drag:function(v){ if(M.k == 'd')E.css({left:M.X+v.pageX-M.pX,top:M.Y+v.pageY-M.pY}); else E.css({width:Math.max(v.pageX-M.pX+M.W,0),height:Math.max(v.pageY-M.pY+M.H,0)}); return false;}, stop:function(){E.css('opacity',M.o);$(document).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});$(document).mousemove($.jqDnR.drag).mouseup($.jqDnR.stop); return false; }); });}, f=function(k){return parseInt(E.css(k))||false;}; })(jQuery);
即可
jquery1.4后 jqDrag 拖动 不可用
