这里默认读者清楚 ES6 的语法
export default new vuex.Store({
state : {
user : {
list: [],
total: 0,
pageIndex: 1,
pageSize: 10,
}
},
mutations: {
updateUser(state, data) {
state.user = {
...state.user,
...data,
}
},
},
actions: {
async getUser({commit,state,getters}) {
// $axios 只是我自己封装的一个函数 这里并不重要
const res = await $axios.get('/user',getters.requestData(state.user))
commit('updateUser',res);
},
},
getters:{
requestData(state) {
return (origin) => {
const {
pageIndex,
pageSize,
} = origin;
const data = {
pageIndex,
pageSize,
};
return data;
}
},
}
})数据持久化
现在如何获取数据已经搞定了，数据持久化我使用 vuex-localstorage，安装后，只需要在上面代码的基础上添加：
import createPersist from 'vuex-localstorage'
export default new vuex.Store({
// 接着上面的
plugins: [createPersist({
namespace: 'studio-user',
initialState: {},
// ONE_WEEK
expires: 7 * 24 * 60 * 60 * 1e3
})]})
公用分页组件
<template>
<el-Pagination
background
layout="total, sizes, prev, pager, next, jumper"
:total="module.total"
:current-page.sync="module.pageIndex"
:page-sizes="module.pageSizes"
:page-size.sync="module.pageSize"
@current-change="handleCurrentChange"
@size-change="handleSizeChange"
>
</el-Pagination>
</template>
<script>
export default {
props: {
module: Object
},
methods: {
getData() {
this.$emit("get-data");
},
handleCurrentChange() {
this.getData();
},
handleSizeChange(val) {
this.getData();
}
}
};
</script>
使用分页组件
<template>
<div class="container">
<el-table
:data="user.list"
style="width: 100%;"
>
<el-table-column
v-for="(item,index) in columns"
:key="index"
:prop="item.prop"
:label="item.label"
align="center"
/>
</el-table>
<pagination
:module="user"
@get-data="getData"
/>
</div>
</template>
<script>
import Pagination from "@/common/components/Pagination";
import { mapActions, mapState } from "vuex";
export default {
components: {
Pagination,
},
