Element常用组件—表格、表单、对话框和分页工具条-阿里云开发者社区

一、Element表格

由输入框、选择器、单选框、多选框等控件组成，用以收集、校验、提交数据。

带状态表格：可将表格内容 highlight 显示，方便区分「成功、信息、警告、危险」等内bian

Element表格代码：

<div id="app">
    <!--表格-->
    <template>
        <el-table
                :data="tableData"
                style="width: 100%"
                :row-class-name="tableRowClassName">
            <el-table-column
                    prop="date"
                    label="日期"
                    width="180">
            </el-table-column>
            <el-table-column
                    prop="name"
                    label="姓名"
                    width="180">
            </el-table-column>
            <el-table-column
                    prop="address"
                    label="地址">
            </el-table-column>
        </el-table>
    </template>
</div>

css样式：

<style>
        .el-table .warning-row {
            background: oldlace;
        }
        .el-table .success-row {
            background: #f0f9eb;
        }
</style>

medhods及data对象：

<script>
    new Vue({
        el: "#app",
        methods: {
            tableRowClassName({row, rowIndex}) {
                if (rowIndex === 1) {
                    return 'warning-row';
                } else if (rowIndex === 3) {
                    return 'success-row';
                }
                return '';
            }
        },
        data() {
            return {
                tableData: [{
                    date: '2016-05-02',
                    name: '王小虎',
                    address: '上海市普陀区金沙江路 1518 弄',
                }, {
                    date: '2016-05-04',
                    name: '王小虎',
                    address: '上海市普陀区金沙江路 1518 弄'
                }, {
                    date: '2016-05-01',
                    name: '王小虎',
                    address: '上海市普陀区金沙江路 1518 弄',
                }, {
                    date: '2016-05-03',
                    name: '王小虎',
                    address: '上海市普陀区金沙江路 1518 弄'
                }]
            }
        }
    })
</script>

二、Element表单

由输入框、选择器、单选框、多选框等控件组成，用以收集、校验、提交数据

行内表单：当垂直方向空间受限且表单较简单时，可以在一行内放置表单。

Element表单代码：

<!--搜索表单-->
    <el-form :inline="true" :model="brand" class="demo-form-inline">
        <el-form-item label="当前状态">
            <el-select v-model="brand.status" placeholder="当前状态">
                <el-option label="启用" value="1"></el-option>
                <el-option label="禁用" value="0"></el-option>
            </el-select>
        </el-form-item>
        <el-form-item label="企业名称">
            <el-input v-model="brand.companyName" placeholder="企业名称"></el-input>
        </el-form-item>
        <el-form-item label="品牌名称">
            <el-input v-model="brand.brandName" placeholder="品牌名称"></el-input>
        </el-form-item>
        <el-form-item>
            <el-button type="primary" @click="onSubmit">查询</el-button>
        </el-form-item>
    </el-form>

方法：

methods: {
      onSubmit() {
        console.log('submit!');
      }
    }

data：

执行结果：

三、Element对话框

在保留当前页面状态的情况下，告知用户并承载相关操作。

基本用法：Dialog 弹出一个对话框，适合需要定制性更大的场景。

Element代码：

<el-dialog
  title="提示"
  :visible.sync="dialogVisible"
  width="30%"
  :before-close="handleClose">
  <span>这是一段信息</span>
  <span slot="footer" class="dialog-footer">
    <el-button @click="dialogVisible = false">取 消</el-button>
    <el-button type="primary" @click="dialogVisible = false">确 定</el-button>
  </span>
</el-dialog>

标记：

//添加数据对话框是否展示的标记
                dialogVisible: false,

按钮：

<el-row>
        <el-button type="danger" plain>批量删除</el-button>
        <el-button type="primary" plain @click="dialogVisible = true">新增</el-button>
    </el-row>

执行结果：

四、Element分页工具条

Pagination 分页：当数据量过多时，使用分页分解数据。

附加功能：根据场景需要，可以添加其他功能模块。

<!--分页工具条-->
    <el-pagination
            @size-change="handleSizeChange"
            @current-change="handleCurrentChange"
            :current-page="currentPage"
            :page-sizes="[5, 10, 15, 20]"
            :page-size="5"
            layout="total, sizes, prev, pager, next, jumper"
            :total="400">
    </el-pagination>

执行结果：

五、结合之后的组件代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .el-table .warning-row {
            background: oldlace;
        }
        .el-table .success-row {
            background: #f0f9eb;
        }
    </style>
</head>
<body>
<div id="app">
    <!--搜索表单-->
    <el-form :inline="true" :model="brand" class="demo-form-inline">
        <el-form-item label="当前状态">
            <el-select v-model="brand.status" placeholder="当前状态">
                <el-option label="启用" value="1"></el-option>
                <el-option label="禁用" value="0"></el-option>

                <el-input v-model="brand.ordered"></el-input>
            </el-form-item>
            <el-form-item label="备注">
                <el-input type="textarea" v-model="brand.description"></el-input>
            </el-form-item>
            <el-form-item label="状态">
                <el-switch v-model="brand.status"
                           active-value="1"
                           inactive-value="0"
