解决方案
解决方案二：
script里打alert确定有没运行
解决方案三：
引用1楼xdashewan的回复:
script里打alert确定有没运行
是//页面第一次加载完成后调用的函数F.ready(function(){registerNumberChangeEvents();registerSelectionChangeEvents();updateTotal();});没有运行
解决方案四：
引用1楼xdashewan的回复:
script里打alert确定有没运行
恩没有运行还有就是F.ready（）这个东西没有运行
解决方案五：
把script放到head标签内，或者放到最下面的html下面。

放在head内出错，放在html下面还是更原来一样的效果示例原网站：http://fineui.com/demo/#/demo/grid/grid_edit_cart.aspx
