Instead, use a data or computed property based on the prop's value. Prop being mutated: "xxx"

Instead, use a data or computed property based on the prop's value. Prop being mutated: "xxx"

解决方法：

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "batchColOptions"

因为prop里面定义的属性都单向绑定，父组件传过来的值，子组件不能更改数据，如果想和父组件通讯可以使用$emit 和 $on，可参考：http://www.yayihouse.com/yayishuwu/chapter/2618
