jquery 拖拽插件easydrag点击位置偏移问题

$.updatePosition = function(e) {var pos = $.getMousePosition(e);var spanX = (pos.x - lastMouseX);var spanY = (pos.y - lastMouseY);if(lastElemTop + spanY != 0){$(currentElement).css("top",  (lastElemTop + spanY));}if(lastElemLeft + spanX != 0){$(currentElement).css("left", (lastElemLeft + spanX));}else{$(currentElement).css("left", -$(currentElement).width());}};

只点击时lastElemLeft + spanX == 0而此情况下，插件会偏移一个当前Div的宽度，因此添加处理$(currentElement).css("left", -$(currentElement).width());
