react in a form using AntD

react in a form using AntD

1. The two-way data binding

render() {
    const { getFieldDecorator } = this.props.form;//双向数据绑定
    return (
      <div>
        <Form >
          <FormItem label="姓名">
            {getFieldDecorator('userName')(
              <Input></Input>
            )}
          </FormItem>
        </Form>
      </div>
    );
 }

important point

• We will complain directly, use Form.create (options) to accept the data
  and finally add the following code to the js file

form = Form.create({})(form);
export default form

• Set the initial value of the time

Can not be used directly in the form in value=, this will error:

Warning: getFieldDecorator will override value, so please don’t set value directly and use setFieldsValue to set it.

InitalValue need to set the required values ​​of getFieldDecorator

 <Form.Item key={i} >
            {getFieldDecorator(field,{
              initialValue:item.initLabel,//设置的默认值
            })(
              <Select
                style={{ width: '120' }}
                onChange={this.handleCurrencyChange}
              >
                {BaseUI.getOptionList(item.Options)}
              </Select>
            )}
</Form.Item>

2. Get form data

Here is detached to form separate components userForm an example
we introduce userForm components in other pages

 <UserForm wrappedComponentRef={(form) => this.userForm = form}>
 </UserForm>

wrappedComponentRefVue equivalent to the ref, so this.userformthat the dom node

• retrieve data
  this.userForm.props.form.getFieldsValue()
• Data Reset
  this.userForm.props.resetFields()

Please refer to the document antd

3. Form Validation

Basic usage

<Form.Item key="author">
{getFieldDecorator("author", { rules: [{ required: true, message: '请输入作者!' }] })
(<Input placeholder="作者" allowClear />)}
</Form.Item>

Custom validation

checkPhone = (rule, value, callback) => {
    let reg = /^1(3|4|5|7|8)\d{9}$/;
    if (!value) {
      callback("请输入手机号")
    }
    else if (!reg.test(value)) { callback("请输入正确的手机号格式") }
    else {
      callback()
    }
}
...
<Form.Item key="phone">
{getFieldDecorator("phone", { rules: [{ validator: this.checkPhone }], })
(<Input placeholder="手机号" allowClear />)}
</Form.Item>
