## 新建列表页面
1. 我们先做一个最简单的列表页面
2. 列表页面完整代码如下：
~~~
<template>
<basic-container>
<el-row>
<el-col :span="24">
<div class="tool-box">
<el-button type="primary" icon="el-icon-circle-plus-outline" size="small" @click="handleAdd">新增</el-button>
<el-button type="danger" icon="el-icon-delete" size="small" @click="handleMultiDelete">批量删除</el-button>
</div>
</el-col>
</el-row>
<el-row>
<el-table
:data="data"
@selection-change="selectChange"
style="width: 100%">
<el-table-column
prop="id"
type="selection"
width="55">
</el-table-column>
<el-table-column
prop="title"
label="标题"
width="180">
</el-table-column>
<el-table-column
prop="content"
label="内容">
</el-table-column>
<el-table-column
prop="time"
label="日期"
width="180">
</el-table-column>
<el-table-column label="操作" fixed="right" width="250">
<template slot-scope="scope">
<el-button
size="mini"
type=""
plain
@click="handleView(scope.$index, scope.row)">查看
</el-button>
<el-button
size="mini"
type="primary"
plain
@click="handleEdit(scope.$index, scope.row)">编辑
</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">删除
</el-button>
</template>
</el-table-column>
</el-table>
</el-row>
<el-row>
<el-pagination
background
:page-sizes="[10, 20, 30, 50]"
:page-size="10"
layout="total, sizes, prev, pager, next, jumper"
@size-change="sizeChange"
@current-change="currentChange"
:total="page.total">
</el-pagination>
</el-row>
</basic-container>
</template>
<script>
import {getList} from '@/api/demo/blog'
export default {
data() {
return {
data: [],
multiSelection: [],
page: {
pageSize: 10,
currentPage: 1,
total: 0
},
}
},
created() {
this.onLoad();
},
methods: {
onLoad() {
getList().then(res => {
this.data = res.data.data.records;
this.page.total = res.data.data.total;
})
},
selectChange(val) {
this.multiSelection = val
},
currentChange(currentPage){
this.page.currentPage = currentPage;
},
sizeChange(pageSize){
this.page.pageSize = pageSize;
},
handleAdd() {
console.log("add")
},
handleView(index, row) {
console.log("view");
console.log(index);
console.log(row);
},
handleEdit(index, row) {
console.log("edit");
console.log(index);
console.log(row);
},
handleDelete(index, row) {
console.log("delete");
console.log(index);
console.log(row);
},
handleMultiDelete() {
console.log("multi-delete")
},
}
}
</script>
~~~
3. 我们来详细分析每一个代码块的作用及目的
* `<basic-container>` 标签将整个页面包裹在定义好样式的容器内，另布局界面更美观
* 我们改造下demo.vue文件便能看到比之前更好的效果
* 如下代码代表在页面新建一行，定义两个按钮，并用`@click`指定了对应的点击事件
~~~
<el-row>
<el-col :span="24">
<div class="tool-box">
<el-button type="primary" icon="el-icon-circle-plus-outline" size="small" @click="handleAdd">新增</el-button>
<el-button type="danger" icon="el-icon-delete" size="small" @click="handleMultiDelete">批量删除</el-button>
</div>
</el-col>
</el-row>
~~~
* 如下代码代表在页面定义表格控件，用`:data`绑定指定的数据，以及用`@selection-change`绑定选中后的事件
~~~
<el-table
:data="data"
@selection-change="selectChange"
style="width: 100%">
~~~
* 如下代码代表在`el-table`组件内定义了`选项框`、`标题`、`内容`、`日期`的字段
~~~
<el-table-column
prop="id"
type="selection"
width="55">
</el-table-column>
<el-table-column
prop="title"
label="标题"
width="180">
</el-table-column>
<el-table-column
prop="content"
label="内容">
</el-table-column>
<el-table-column
prop="time"
label="日期"
width="180">
</el-table-column>
~~~
* 如下代码代表定加入操作栏，并且定义了`查看`、`编辑`、`删除`三个按钮以及他们对应的点击事件
~~~
<el-table-column label="操作" fixed="right" width="250">
<template slot-scope="scope">
<el-button
size="mini"
type=""
plain
@click="handleView(scope.$index, scope.row)">查看
</el-button>
<el-button
size="mini"
type="primary"
plain
@click="handleEdit(scope.$index, scope.row)">编辑
</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">删除
</el-button>
</template>
</el-table-column>
~~~
* 如下代码定义了分页组件，并绑定了`size-change`与`current-change`两个事件
~~~
<el-pagination
background
:page-sizes="[10, 20, 30, 50]"
:page-size="10"
layout="total, sizes, prev, pager, next, jumper"
@size-change="sizeChange"
@current-change="currentChange"
:total="page.total">
</el-pagination>
~~~
* 如下代码则是定义了vue的各种事件，与table组件相互绑定
~~~
<script>
import {getList} from '@/api/demo/blog'
export default {
data() {
return {
data: [],
multiSelection: [],
page: {
pageSize: 10,
currentPage: 1,
total: 0
},
}
},
created() {
this.onLoad();
},
methods: {
onLoad() {
getList().then(res => {
this.data = res.data.data.records;
this.page.total = res.data.data.total;
})
},
selectChange(val) {
this.multiSelection = val
},
currentChange(currentPage){
this.page.currentPage = currentPage;
},
sizeChange(pageSize){
this.page.pageSize = pageSize;
},
handleAdd() {
console.log("add")
},
handleView(index, row) {
console.log("view");
console.log(index);
console.log(row);
},
handleEdit(index, row) {
console.log("edit");
console.log(index);
console.log(row);
},
handleDelete(index, row) {
console.log("delete");
console.log(index);
console.log(row);
},
handleMultiDelete() {
console.log("multi-delete")
},
}
}
</script>

4. 下面我们刷新页面，查看下具体效果
5. 我们发现分页距离表格太靠近了，这样不美观，需要做一下样式处理，在最下方加入如下样式
~~~
<style lang="scss" scoped>
.el-pagination {
margin-top: 20px;
}
</style>
~~~
6. 再次刷新页面，发现样式调整恰到好处
7. 最简单的列表页已经完成，下面几章我们来分别处理增改查三个对应的操作
