[Vue warn]: The data property "orderId" is already declared as a prop.Use prop default value instead
在使用Vue開發中,使用元件時報了這麼一個錯誤:
[Vue warn]: The data property "list" is already declared as a prop. Use prop default value instead.
翻譯的白話就是:“list”已經在prop聲明瞭.
錯誤程式碼:
export default { props:{ list:{ type:Array, }, }, data(){ return { list:'', } } }
原來props的優先順序 > data中的優先順序 > menthods中的優先順序,所以去掉data裡面的list定義即可
修改後程式碼:
export default {
props:{
list:{
type:Array,
},
},
data(){
return {
}
}
}
