目录
本次目标：
- 表单验证
- 增删改
一、表单校验
1.出现表单组件 el-form
Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
并将Form-Item的prop属性设置为需校验的字段名即可
在Articles的div里面增加编辑界面
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
<el-form-item label="文章标题" prop="title">
<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
</el-form-item>
<el-form-item label="文章内容" prop="body">
<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入内容"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button size="small" @click="closeDialog">取消</el-button>
<el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
</div>
</el-dialog>
2. 通过点击 新增/编辑将表单对应窗口弹出
默认false
点击添加改为true
效果：
代码：
<template>
<div>
<!-- 搜索筛选 -->
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索：">
<el-input size="small" v-model="formInline.title" placeholder="请输入文章标题"></el-input>
</el-form-item>
<el-form-item>
<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
<el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button>
</el-form-item>
</el-form>
<el-table size="small" :data="listData" highlight-current-row style="width: 100%;">
<el-table-column align="center" type="selection" width="60">

<el-table-column sortable prop="id" label="文章id" width="300">
</el-table-column>
<el-table-column sortable prop="title" label="文章标题" width="300">
</el-table-column>
<el-table-column sortable prop="body" label="文章内容" width="300">
</el-table-column>
<el-table-column align="center" label="操作" min-width="300">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
:current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
:total="formInline.total">
</el-pagination>
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
<el-form-item label="文章标题" prop="title">

<div slot="footer" class="dialog-footer">
<el-button size="small" @click="closeDialog">取消</el-button>
<el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
</div>
</el-dialog>
</div>
</template>
<script>
export default {
name: 'Articles',
data() {
return {
title:'',
editFormVisible:false,
editForm:{
title:'',
body:''
},
listData: [],
formInline: {
page: 1,
total: 10,
title:''
}
};
},
methods: {
handleEdit() {
},
deleteUser() {
},
handleSizeChange(rows) {
console.log("页面大小发送改变");
this.formInline.page = 1;
this.formInline.rows = rows;
this.search();
},
handleCurrentChange(page) {
console.log("当前页发送改变");
this.formInline.page = page;
this.search();
},
//代码复用
doSearch(param) {
let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
this.axios.post(url, param)
.then(resp => { //箭头函数 jdk8的语法
//成功的回调函数
console.log(resp);
this.listData = resp.data.result;
this.formInline = resp.data.pageBean;
})
.catch(function() { // 代表失败
});
},
search(){
//按照条件进行查询
this.doSearch(this.formInline);
},
closedialog(){
//关闭窗体
},
handleEdit(){
//展示新增文章的表单窗体
this.editFormVisible = true;
}
},
//钩子函数
created() {
this.doSearch({});
}
}
</script>
<style>
</style>
3. 给表单设置规则 rules
Articles.vue
<template>
<div>
<!-- 搜索筛选-->
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索：">
<el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
</el-form-item>
<el-form-item>
<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
<el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button>
</el-form-item>
</el-form>
<!--列表-->
<el-table size="small" :data="listData" highlight-current-row style="width: 100%;">
<el-table-column align="center" type="selection" min-width="60">
</el-table-column>
<el-table-column sortable prop="id" label="文章ID" min-width="300">
</el-table-column>
<el-table-column sortable prop="title" label="文章标题" min-width="300">
</el-table-column>
<el-table-column sortable prop="body" label="文章内容" min-width="300">
</el-table-column>
<el-table-column align="center" label="操作" min-width="300">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
:current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100"
layout="total, sizes, prev, pager, next, jumper" :total="formInline.total">
</el-pagination>
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
<el-form-item label="文章标题" prop="title">
<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
</el-form-item>
<el-form-item label="文章内容" prop="body">
<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button size="small" @click="closeDialog">取消</el-button>
<el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
</div>
</el-dialog>
</div>
</template>
<script>
export default {
name: 'Articles',
data() {
return {
title: '',
editFormVisible: false,
editForm: {
title: '',
body: '',
id : 0
},
rules: {
title: [{
required: true,
message: '请输入文章标题',
trigger: 'blur'
},
{
min: 5,
max: 10,
message: '长度须在 5 到 10 个字符之间',
trigger: 'blur'
}
],
body: [{
required: true,
message: '请输入文章内容',
trigger: 'blur'
}],
},
listData: [],
formInline: {
page: 1,
total: 10,
title: ''
}
}
},
methods: {
handleSizeChange(rows) {
// console.log("页面发生改变")
this.formInline.page = 1;
this.formInline.rows = rows;
this.search();
},
handleCurrentChange(page) {
// console.log("当前页码发生改变")
this.formInline.page = page;
this.search();
},
//是为了代码复用
doSearch(param) {
// 获取树形节点的数据
let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
//this指的是vue实例
this.axios.post(url, param)
.then(resp => { //代表成功 箭头函数 jdk8的语法
console.log(resp);
this.listData = resp.data.result;
this.formInline = resp.data.pageBean;
}).catch(function() { //代表失败
});
},
search() {
// 按照条件进行查询
this.doSearch(this.formInline);
},
closeDialog() {
// 关闭窗体
},
clearData(){
// 清除编辑窗体的缓存数据
this.editForm.title= '';
this.editForm.id = 0;
this.editForm.body = '';
},
handleEdit() {
// 展示新增文章的表单
this.editFormVisible = true;
this.title = '新增窗体';
},
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
// let url =this.axios.urls.SYSTEM_ARTICLE_ADD;
alert('submit!');
} else {
console.log('error submit!!');
return false;
}
});
}
},
created() {
this.doSearch({});
}
}
</script>
<style scoped>
</style>
校验结果：
4.当表单提交时要校验规则
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
alert('submit!');
} else {
console.log('error submit!!');
return false;
}
});
}
存在问题：有缓存，而且后期我们编辑和增加弹出的是同一个窗口，要进行判断（后面CRUD优化）
二、增删改
1. 保障编辑窗体能够正常弹出
因为我们编辑和新增用的是同一个方法，所有我们要再其进行判断弹框，因为我们有缓存问题，所有我们还要新增一个清除缓存的方法，在关闭窗体调用
修改点击添加或修改的方法
handleEdit(index, row) {
this.clearData();
// 展示新增文章的表单
this.editFormVisible = true;
if (row) {
// 编辑
this.title = '编辑窗体';
this.editForm.id = row.id;
this.editForm.title = row.title;
this.editForm.body = row.body
} else {
//新增
this.title = '新增窗体';
}
}清除编辑窗体的缓存数据
clearData() {
//清除编辑窗体的缓存数据
this.editForm.title = '';
this.editForm.id = 0;
this.editForm.body = '';
this.title = '';
this.editFormVisible = false;
}关闭窗体调用
closeDialog() {
// 关闭窗体
this.clearData();
}
效果：
2. 新增与修改
修改保存按钮的方法
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
let url;
if (this.editForm.id == 0) {
//新增
url = this.axios.urls.SYSTEM_ARTICLE_ADD;
} else {
//修改
url = this.axios.urls.SYSTEM_ARTICLE_EDIT;
}
this.axios.post(url, this.editForm).then(r => {
// 新增成功之后，1、关闭窗体 ，清空数据 2、重新查询
this.$message({
message: r.data.msg,
type: 'success'
});
this.closeDialog();
this.search();
}).catch(e => {
})
} else {
console.log('error submit!!');
return false;
}
});

});
});
},删除一下：
