Vue_10_Spa_项目4次-CRUD+表单验证
本文主要是介绍Vue_10_Spa_项目4次-CRUD+表单验证，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
一、表单验证
在分页条下面放入编辑组件el-dialog：
<!-- 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>
在script的date里面写入：
rules: {
title: [{
required: true,
message: '请输入文章标题',
trigger: 'blur' /* trigger：触发器 */ /*blur失去焦点的时候触发 */
},
{
/* 非空验证 */
min: 3,
max: 5,
message: '长度在 3 到 5 个字符',
trigger: 'blur'
}
],
body: [{
required: true,
message: '请输入文章内容',
trigger: 'change'
}]
}
写入新增方法：
handleEdit(){//新增
this.editFormVisible =true;
},
校验方法：
submitForm(formName) { //校验方法
this.$refs[formName].validate((valid) => {
if (valid) {
alert('submit!');
} else {
console.log('error submit!!');
return false;
}
});
},
二、增删改功能实现
先把之前注释了的操作按钮放开：
<el-table-column align="center" label="操作" min-width="2">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
定义回显：
editForm: {/* 定义回显 */
title:'',
body:'',
id:0
},
以及编辑窗口 ：
handleEdit() { //新增
this.editFormVisible = true;
// console.log(row);
if(row){
this.title = '编辑窗口';
this.editForm.id = row.id;
this.editForm.title = row.title;
this.editForm.body = row.body;
}else{
this.title='新增窗口';
}
},
实现点击修改也能弹出文本窗口有数据回显：
handleEdit(index,row) { //新增
this.clearData();
this.editFormVisible = true;
// console.log(row);
if(row){
this.title = '编辑窗口';
this.editForm.id = row.id;
this.editForm.title = row.title;
this.editForm.body = row.body;
}else{
this.title='新增窗口';
}
},
校验新增与修改：
submitForm(formName) { //校验方法
this.$refs[formName].validate((valid) => {
if (valid) {
let url;
if(this.editForm.id == 0){
url=this.axios.urls.SYSTEM_ARTICLE_ADD;//新增
}else{
url=this.axios.urls.SYSTEM_ARTICLE_EDIT;//修改
}
this.axios.post(url, this.editForm).then((resp) =>{
console.log(resp);
this.clearData();
this.search();
}).catch(function(error) {
console.log(error);
});
} else {
console.log('error submit!!');
return false;
}
});
},
注：图片在尾部
删除方法：
deleteUser(index,row){
this.editForm.id = row.id;
let url=this.axios.urls.SYSTEM_ARTICLE_DEL;//删除
this.axios.post(url, this.editForm).then((resp) =>{
console.log(resp);
this.clearData();
this.search();
}).catch(function(error) {
console.log(error);
});
},
注：图片在尾部
Articles.vue全代码：
<template>
<div>
<!-- 这是文章列表组件 -->
<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>
<!-- 列表-->
<el-table size="small" :data="listData" highlight-current-row border element-loading-text="拼命加载中"
style="width: 100%;">
<!--
<el-table-column align="center" type="selection" min-width="1">
</el-table-column> -->
<el-table-column sortable prop="id" label="文章ID" min-width="1">
</el-table-column>
<el-table-column sortable prop="title" label="文章标题" min-width="3">
</el-table-column>
<el-table-column sortable prop="body" label="文章内容" min-width="5">
</el-table-column>
<el-table-column align="center" label="操作" min-width="2">
<template slot-scope="scope">

<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-->
