報錯 [Vue warn]: Avoid mutating a prop directly since the value will be overwritte

在vue2.0中子組件觸發改變值的時候vue組件會報出例如：[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: "selectType"

組件內直接修改props的值會報錯

解決方法： 在子組件使用該值時須要通過新變量（chooseType）從新傳遞，這樣當這個值變動時，不會造selectType的更改
