Usage

常用

import FormLite from 'formlite';
import DatePicker from './DatePicker';
import Input from './Input';
import FormRenderer from './FormRenderer';

FormLite.registerComponent([DatePicker, Input]); // 注册可用的组件
FormLite.setDefaultItemRenderer(FormRenderer); // 设置表单渲染模板默认值
FormLite.setDefaultMode(FormLite.ALL); // 设置表单值变化时验证模式， ALL: 自动验证所有值, ITEM: 只验证当前修改值， NONE: 不自动验证

@FormLite
class Example extends React.Component{
  onDateChange = (name, value)=>{
    console.log(value);
    this.props.form.setValues({c: value.format('YYYY-MM-DD hh:mm:ss')});
    return true;
  };
  render(){
    let {Input, DatePicker} = this.props.form;
    return (
      <div>
        <Input name="a" style={{color: 'blue'}}/>
        <Input name="b"/>
        <Input name="c"/>
        <Input name="c" style={{color: 'blue'}} readOnly/>
        <DatePicker name="d" onChange={this.onDateChange}/>
        <button onClick={this.onSubmit}>submit</button>
        <button onClick={this.onReset}>reset</button>
      </div>
    );
  }
