js实现配置菜品规格时，向后台传一个json格式字符串

由于本公司做的是订餐平台，那么在上传菜品时，需要配置菜品规格，比如份量（大中小），味道(猛辣，中辣，微辣) 由于这些数据，在表的设计时 没有保存到菜品表，那么在点击保存菜品数据时，配置规格这块数据，我就封装好一个json 格式字符串传给后台再把json转换成对象，这样后台就好处理多了。

三，页面效果

四，》》》》json 格式数据

规格

[{"id":"","name":"大份","price":"15","dishesId":"4629"},{"id":"","name":"中份","price":"12","dishesId":"4629"},{"id":"","name":"小份","price":"10","dishesId":"4629"}]

属性

[{"id":"3","name":"味道","dishesId":"4629","dishesParamItemList":[{"id":"7","name":"加糖","additionPrice":"1.0","dishesParamId":"3","dishesId":"4629"},{"id":"8","name":"加酸","additionPrice":"2.0","dishesParamId":"3","dishesId":"4629"}]},{"id":"4","name":"温度","dishesId":"4629","dishesParamItemList":[{"id":"9","name":"加热","additionPrice":"0.5","dishesParamId":"4","dishesId":"4629"},{"id":"10","name":"加冰","additionPrice":"0.2","dishesParamId":"4","dishesId":"4629"}]}]

其中dishesId 菜品ID 表的设计和 和对象代码我就不贴出来了。可以看json 格式数据去设计表。
