表单构建器事务代码

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。

React相关技术
antd

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

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;
Vue相关技术
ElementUI

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

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>
