watch items 那里有問題，handler拼的對不對

const STORAGE_KEY='todos-vuejs'
export default{
?fetch(){
? ?return JSON.parse(window.localStorage.getItem(STORAGE_KEY)||'[]')
?},
?save(items){
? ?window.localStorage.setItem(STORAGE_KEY,JSON.stringify(items))
?}
}
我的問題解決了，items參數傳錯了

我也是同樣的問題，請問老師，怎么解決，謝謝

請問是什么原因，怎么解決的？謝謝?

handler:(val,oldVal)=>{} 這樣會報錯，箭頭函數導致this指向出錯，改成handler:function(val,oldVal){}這樣就好了。

App.vue是作為main.js中的組件使用的, 所以在App.vue中初始化對象時需要用函數返回聲明,
export default {
????data () {
????????return {
????????????items : Store.getStorage(),
????????????newItem: ''
????????}
????}
}
我覺得是這樣的

[Vue warn]: Error in callback for watcher "items": "ReferenceError: items is not defined"
我的是這樣

store.js文件中的save方法的需要傳遞參數items
