邮箱验证

表单

<el-form ref="ValidateForm"  :model="Form" :rules="rules">

	<el-form-item prop="email">
		<el-input v-model="Form.email" placeholder="邮箱" clearable class="input-ui">
		   <template #prefix>
		       <svg-icon icon-class="message" />
		   </template>
		</el-input>
	</el-form-item>
		  
		  <el-button @click="submitForm('ValidateForm')" :loading="loading">提交</el-button>
		  
</el-form>

在Vue中，我们不用获取dom节点，元素绑定ref之后，直接通过this.$refs即可调用,这样可以减少获取dom节点的消耗。

提交验证

export default{
	data(){
		return{
			Form:{
				email:''
			},
			rules: {
			    email: [
					{ required: true, message: '请输入邮箱', trigger: 'blur' },
			        { min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur' },
					{ type: 'email', message: '请输入正确的邮箱地址', trigger: ['blur', 'change'] }
			    ],
			},
			loading:false
		}
	},
	methods:{
		// 提交表单
		submitForm(ValidateForm) {
			
			this.$refs[ValidateForm].validate((valid) => {
			  if (valid) {
				
				console.log('submit!')
				this.loading = true
				setTimeout(()=>{
					this.loading = false
				},1500)
			  } else {
				console.log('error submit!!');
				return false;
			  }
			})
			
		},
	}
}

密码验证

表单

<el-form-item label="新密码" prop="password" label-width="85px">
        <el-input v-model="Form.password" placeholder="请输入新密码" type="password" clearable  />
</el-form-item>
			
<el-form-item label="确认密码" prop="passwordConfirm" label-width="85px">
         <el-input v-model="Form.passwordConfirm" placeholder="请输入确认密码" type="password" clearable  />
</el-form-item>

设置label-width宽度是为了标题长度一样达到美观效果

验证

rules: {
		password: [
			{ required: true, message: '请输入新密码', trigger: 'blur' },
			{ min: 6, max: 20, message: '长度在 6 到 20 个字符', trigger: 'blur' }
		],
		passwordConfirm: [
			{ required: true, trigger: 'blur', message: '确认密码不能为空' },
			{
				validator: (rules, value, callback) => {
					  if (value !== this.Form.password) callback(new Error('确认密码与新密码不一致'))
					  callback()
				}, trigger: 'blur'
			}
		]	
},
