表单构建器事务代码是一种通过编写代码方式动态生成表单的工具,它可以大大提高表单的可重用性和维护性。下面介绍一些常见的表单构建器事务代码技术。
antd是一个基于React的UI库,它提供了很多可重用的组件,包括表单控件。通过antd,我们可以很容易地构建出样式美观、交互良好的表单。
以下是一个示例代码,用于构建一个antd的Form组件:
import React from 'react';
import { Form, Input, Button } from 'antd';
const layout = {
labelCol: { span: 8 },
wrapperCol: { span: 16 },
};
const tailLayout = {
wrapperCol: { offset: 8, span: 16 },
};
const Demo = () => {
const onFinish = (values) => {
console.log('Success:', values);
};
const onFinishFailed = (errorInfo) => {
console.log('Failed:', errorInfo);
};
return (
<Form
{...layout}
name="basic"
initialValues={{ remember: true }}
onFinish={onFinish}
onFinishFailed={onFinishFailed}
>
<Form.Item
label="Username"
name="username"
rules={[{ required: true, message: 'Please input your username!' }]}
>
<Input />
</Form.Item>
<Form.Item
label="Password"
name="password"
rules={[{ required: true, message: 'Please input your password!' }]}
>
<Input.Password />
</Form.Item>
<Form.Item {...tailLayout}>
<Button type="primary" htmlType="submit">
Submit
</Button>
</Form.Item>
</Form>
);
};
export default Demo;
Formik是一个专门用于处理表单逻辑的库,它提供了表单状态管理、表单验证、表单提交等功能,并且可以与React、React Native等框架配合使用。
以下是一个示例代码,用于构建一个Formik的表单:
import React from 'react';
import { Formik, Form, Field, ErrorMessage } from 'formik';
import * as Yup from 'yup';
const initialValues = {
username: '',
password: '',
};
const validationSchema = Yup.object({
username: Yup.string().required('Required'),
password: Yup.string().required('Required'),
});
const onSubmit = (values, { setSubmitting }) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
setSubmitting(false);
}, 400);
};
const Demo = () => (
<Formik
initialValues={initialValues}
validationSchema={validationSchema}
onSubmit={onSubmit}
>
{({ isSubmitting }) => (
<Form>
<Field type="text" name="username" placeholder="Username" />
<ErrorMessage name="username" />
<Field type="password" name="password" placeholder="Password" />
<ErrorMessage name="password" />
<button type="submit" disabled={isSubmitting}>
Submit
</button>
</Form>
)}
</Formik>
);
export default Demo;
ElementUI是一个基于Vue的UI库,它提供了很多可重用的组件,包括表单控件。通过ElementUI,我们可以很容易地构建出样式美观、交互良好的表单。
以下是一个示例代码,用于构建一个ElementUI的表单:
<template>
<el-form :model="form" :rules="rules" ref="form">
<el-form-item label="Username" prop="username">
<el-input v-model="form.username"></el-input>
</el-form-item>
<el-form-item label="Password" prop="password">
<el-input type="password" v-model="form.password"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="submitForm('form')">Submit</el-button>
</el-form-item>
</el-form>
</template>
<script>
export default {
data() {
return {
form: {
username: '',
password: '',
},
rules: {
username: [{ required: true, message: 'Please input your username', trigger: 'blur' }],
password: [{ required: true, message: 'Please input your password', trigger: 'blur' }],
},
};
},
methods: {
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
alert('submit success');
} else {
return false;
}
});
},
},
};
</script>
VeeValidate是一个专门用于处理表单验证的库,它提供了表单验证、表单提交等功能,并且可以与Vue、Nuxt、Quasar等框架配合使用。
以下是一个示例代码,用于构建一个VeeValidate的表单:
<template>
<form @submit.prevent="submitForm">
<div>
<label for="username">Username:</label>
<input type="text" id="username" v-model="form.username" v-validate="'required'" />
<span>{{ errors.first('username') }}</span>
</div>
<div>
<label for="password">Password:</label>
<input type="password" id="password" v-model="form.password" v-validate="'required'" />
<span>{{ errors.first('password') }}</span>
</div>
<div>
<button type="submit" :disabled="errors.any()">Submit</button>
</div>
</form>
</template>
<script>
import { useField, useForm } from 'vee-validate';
export default {
setup() {
const { handleSubmit, errors } = useForm();
const { value: username, errorMessage: usernameError } = useField(
'username',
'required'
);
const { value: password, errorMessage: passwordError } = useField(
'password',
'required'
);
const form = { username, password };
const submitForm = handleSubmit((values) => {
alert(JSON.stringify(values, null, 2));
});
return {
form,
submitForm,
errors,
usernameError,
passwordError,
};
},
};
</script>
以上就是介绍表单构建器事务代码的一些常见技术,它们都可以大大提高表单的可重用性和维护性,帮助开发者更加高效地创建表单。
