CUD表单验证+增删改查
目录
主要内容
1.后台数据接口准备
增删改接口
2.Dialog弹出框
2.1 基本结构
<el-dialog :title="title" :visible.sync="dialogFormVisible" @close="dialogClose">
<!-- form表单 -->
<el-form :label-position="labelPosition" :model="bookForm" :rules="rules" ref="bookForm">
...
</el-form>
</el-dialog>
注1:隐藏显示设置,通过Vue实例对象中的dialogFormVisible="true|false"来控制dialog显示隐藏
:visible.sync=“dialogFormVisible”
注2:通过close或closed事件,在关闭dialog弹出框时清空form表单数据和验证信息;
@close=“dialogClose”
3.表单
3.1 基本结构
...注1::label-position设置表单对齐方式
注2:设置表单元素属性双向绑定的对象属性名称
data: function() {
return {
bookForm: {
id: null,
bookname: null,
price: '',
booktype: null
}
};
}
3.2 表单验证
<el-form :model="bookForm" :rules="rules" ref="bookForm">
...
</el-form>
注1::rules="rules"表单验证定义,只需要通过 rules 属性传入约定的验证规则
//将el-form-item的prop属性设置为需校验的字段名即可,如下:
<el-form-item label="书本名称" prop="bookname" :label-width="formLabelWidth">
<el-input v-model="bookForm.bookname" autocomplete="off"></el-input>
</el-form-item>
//在Vue实例的data属性中定义表单验证规则,如下:
rules: {
bookname: [
{required: true,message: '请输入书本名称!',trigger: 'blur'},
{min: 3,max: 6,message: '长度必须在3-6个字符之间',trigger: 'blur'}
],
...
}
注2:有多个表单,怎么在提交进行区分?
我们在rules这里写了对表单的验证规则,但是我们如何在methods里进行指定的表单进行认证,
所以我们一开始就在el-form里写了 ref="ruleForm",我们在methods里就可以用
注3:清空表单验证信息
this.$refs[formName].resetFields();
补充说明:formName是指<el-form ref="bookForm">中定义的ref属性名
注4:表单重置时必须先清空表单验证信息,再清空表单数据信息
//通过form表单的ref属性来清空表单验证信息
this.$refs['bookForm'].resetFields();
//清空上一次表单的数据信息
this.bookForm.id = null;
this.bookForm.bookname = null;
this.bookForm.price = null;
this.bookForm.booktype = null;
- CUD
2.1 新增
在事件中设置dialogFormVisible="true"即可打开dialog弹出框
2.2 添加修改/删除按钮
2.3 在上使用特殊的slot-scope 特性,可以接收传递给插槽的prop
slot-scope:类似将每一行的row对象封装到槽中,之后直接从scope中获取row对象信息和行索引index信息即可

<!-- 编辑窗体 -->
<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">

加rules的验证
rules: {
title: [{
required: true,
message: '请输入文章标题',
trigger: 'blur'
},
{
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: 'blur'
}]
}
