注意(適合小項目,不用vuex的情況下使用)
1.創建store.js 最好和main.js平級創建文件
import Vue from 'vue' export const store = Vue.observable({ name: '李四' }) export const mutations = { setName (data) { store.name = data } }
2.在兩個組件中調用改寫 (如果全局都有使用,也可在mian.js通過Vue.pototype來全局掛載,不用每個組件都引入)
<template>
<el-row>
<span @click="findClick">{{data}}</span>
</el-row>
</template>
<script>
import {store, mutations} from '@/store.js'
export default {
name: 'mainView',
data() {
return {
data: ''
}
},
mounted() {
this.data = store.name // 引入store.js 通過定義的store直接獲取
},
methods: {
findClick() {
this.$router.push({path: '/login'})
mutations.setName('我改了') // 引入store.js 通過定義的mutations下邊的方法修改
}
}
}
</script>
<style scoped lang="less">
span {
cursor: pointer;
}
.add {
pointer-events: none;
}
</style>
