一、项目需求

在项目中一个页面中需要实现多个Form表单，并在页面提交时需要对多个Form表单进行校验，多个表单都校验成功时才能提交。

二、实现效果

三、多个表单验证

注意项：多个form表单，每个表单上都设置单独的model和ref，不能同时使用，否则每个表单上的校验提示会失效。

<template><div><!-- 表单一区域 --><el-form :inline="true" :model="form1Mode" class="demo-form-inline" ref="form1Ref" :rules="form1Rules"><el-form-item label="表单一" prop="user"><el-input v-model="form1Mode.user" placeholder="form1"></el-input></el-form-item></el-form><!-- 表单二区域 --><el-form :inline="true" :model="form2Mode" class="demo-form-inline" ref="form2Ref" :rules="form2Rules"><el-form-item label="表单二" prop="user"><el-input v-model="form2Mode.user" placeholder="form2"></el-input></el-form-item></el-form><!-- 按钮提交区域 --><div><el-button type="primary" @click="onSubmit">确定</el-button><el-button>取消</el-button></div></div>
</template>

3.1、方式一：依次对两个表单进行校验

<script>
export default {data() {return {form1Mode: {user: ''},form2Mode: {user: ''},form1Rules: {user: [{ required: true, message: '请输入form1', trigger: 'blur' }]},form2Rules: {user: [{ required: true, message: '请输入form2', trigger: 'blur' }]}}},methods: {//确定按钮async onSubmit() {try {await this.$refs.form1Ref.validate()console.log('表单1校验通过')await this.$refs.form2Ref.validate()console.log('表单2校验通过')//都校验成功之后，这里可以发请求this.$message.success('表单校验成功')} catch (error) {console.error('表单校验失败', error)}}}
}
</script>

3.2、方式二：两个表单同时校验------使用Promise.all

<script>
export default {data() {return {form1Mode: {user: ''},form2Mode: {user: ''},form1Rules: {user: [{ required: true, message: '请输入form1', trigger: 'blur' }]},form2Rules: {user: [{ required: true, message: '请输入form2', trigger: 'blur' }]}}},methods: {//封装验证函数submitForm(formUser) {return new Promise((resolve, reject) => {this.$refs[formUser].validate((valid) => {if (valid) {resolve()} else {reject(new Error('错误'))}})})},//确定按钮onSubmit() {Promise.all([this.submitForm('form1Ref'), this.submitForm('form2Ref')]).then(() => {//验证成功后在此处发请求this.$message.success('验证通过')}).catch(() => {this.$message.error('验证失败')})}}
}
</script>
