vue element管理系统基本布局

基本布局： 

包括查询输入框，内容主体，页码切换。

 

 

 传入后台接口包括：

queryInfo: {
                query: '',
                pagenum: 1,
                pagesize: 10
            },

　其中，query表示查询内容，pagenum表示当前页数，pagesize表示每页显示的信息条数

(1)面包屑导航

        <!-- 面包屑导航区域 -->
        <el-breadcrumb separator="/">
            <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
            <el-breadcrumb-item>订单管理</el-breadcrumb-item>
            <el-breadcrumb-item>订单列表</el-breadcrumb-item>
        </el-breadcrumb>

（2）搜索框

            <el-row>
                <el-col :span="8">
                      <el-input placeholder="请输入内容" v-model="queryInfo.query" clearable @clear="getOrderList">
                        <el-button slot="append" icon="el-icon-search" @click="getOrderList"></el-button>
                    </el-input>
                </el-col>
            </el-row>

　　其中， v-model="queryInfo.query" 将搜索框内容双向绑定到queryInfo.query中，

@click="getOrderList" 绑定点击搜索事件
（3）内容

<el-table :data="orderlist" border stripe>
                <el-table-column type="index" label="#"></el-table-column>
                <el-table-column label="订单编号" prop="order_number"></el-table-column>
                <el-table-column label="订单价格" prop="order_price"></el-table-column>
                <el-table-column label="是否付款" prop="pay_status">
                    <template slot-scope="scope">
                        <el-tag type="success" v-if="scope.row.pay_status==='1'">已付款</el-tag>
                        <el-tag type="danger" v-else>未付款</el-tag>
                    </template>
                </el-table-column>
                <el-table-column label="是否发货" prop="is_send"></el-table-column>
                
                <el-table-column label="下单时间" prop="create_time">
                    <template slot-scope="scope">
                        {{scope.row.create_time | dateFormat}}
                    </template>
                </el-table-column>
                <el-table-column label="操作">
                    <template slot-scope="scope">
                        <el-button size="mini" type="primary" icon="el-icon-edit"></el-button>
                        <el-button size="mini" type="success" icon="el-icon-location"></el-button>
                    </template>
                </el-table-column>
            </el-table>

　　<template slot-scope是作用域插槽,可以借助作用域插槽访问或者修改element组件的数据。凡是vue导入的组件，均可以用作用域插槽进行访问修改。

　　（4）页码

<el-pagination @size-change="handleSizeChange"
                @current-change="handleCurrentChange" :current-page="queryInfo.pagenum"
                :page-sizes="[5, 10, 15, 20]" :page-size="queryInfo.pagesize"
                layout="total, sizes, prev, pager, next, jumper" :total="total"
                background>
            </el-pagination>

　　其中，当每页条数改变时，handleSizeChange函数传入新的size参数;当页码改变时，handleCurrentChange传入新的页码参数，根据参数发出响应获得数据。

:page-size，:current-page 分别表示当前大小和页码号， :total为数据量

　

    methods: {
        async getOrderList() {
            const {data: res} = await this.$http.get('orders', {params: this.queryInfo})
            if (res.meta.status !== 200){
                return this.$message.error('获取订单列表失败')
            }
            //console.log(res)
            this.$message.success('获取商品列表成功')
            this.total = res.data.total
            this.orderlist = res.data.goods
        },
        handleSizeChange(newSize) {
            this.queryInfo.pagesize = newSize
            this.getOrderList()
        },
        handleCurrentChange(newPage) {
            this.queryInfo.pagenum = newPage
            this.getOrderList()
        }
    }

　　全部代码
