const SignupForm = () => {
const formik = useFormik({
initialValues: {
email: '',
password: ''
},
validationSchema: Yup.object({
email: Yup.string()
.email('请输入有效的邮箱地址')
.required('必填'),
password: Yup.string()
.min(5, '密码长度不能小于5个字符')
.required('必填')
}),
onSubmit: values => {
console.log(values);
}
});
return (
<form onSubmit={formik.handleSubmit}>
<div className="form-group">
<label htmlFor="email">邮箱地址</label>
<input
id="email"
className="form-control"
type="email"
name="email"
onChange={formik.handleChange}
value={formik.values.email}
/>
{formik.touched.email && formik.errors.email ? (
<div className="alert alert-danger">{formik.errors.email}</div>
) : null}
</div>
<div className="form-group">
<label htmlFor="password">密码</label>
<input
id="password"
className="form-control"
type="password"
name="password"
onChange={formik.handleChange}
value={formik.values.password}
/>
{formik.touched.password && formik.errors.password ? (
<div className="alert alert-danger">{formik.errors.password}</div>
) : null}
</div>
<button type="submit" className="btn btn-primary">
提交
</button>
</form>
);
};
export default SignupForm;
4. Angular Reactive Forms

templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
myForm: FormGroup;
constructor(private fb: FormBuilder) {
this.myForm = this.fb.group({
email: ['', [Validators.required, Validators.email]],
password: ['', [Validators.required, Validators.minLength(5)]]
});
}
onSubmit() {
if (this.myForm.valid) {
console.log(this.myForm.value);
}
}
}
5. Vue.js VeeValidate
Vue.js是一个流行的前端框架,VeeValidate是一个用于Vue.js的表单验证库。以下是一个使用Vue.js VeeValidate创建表单的示例代码:
<template>

<input id="email" v-model="email" @blur="validateEmail" />
<span v-if="errors.email">{{ errors.email }}</span>
</div>
<div>
<label for="password">密码</label>
<input id="password" v-model="password" @blur="validatePassword" />
<span v-if="errors.password">{{ errors.password }}</span>
</div>
<button type="submit">提交</button>
</form>
</div>
</template>
<script>
import { required, email, minLength } from 'vee-validate/dist/rules';
import { extend } from 'vee-validate';
extend('required', required);
extend('email', email);
extend('minLength', minLength);
export default {
data() {
return {
email: '',
password: '',
errors: {}
};
},
methods: {
validateEmail() {
this.errors.email = required(this.email) && email(this.email);
},
validatePassword() {
this.errors.password = required(this.password) && minLength(this.password, 5);
},
onSubmit() {
if (this.email && this.password) {
console.log(this.email, this.password);
}
}
}
};
</script>
