import React, { Component } from 'react';
import bindWithArguments from 'bind-with-arguments';

class Comp extends Component {

   async loadDdetail(id) {
     //	fetch
  }

  //	异步函数并且有参数
  @bindWithArguments
  async asyncParams(id) {
    const detail = await this.loadDdetail(id);
    //	...
  }
  
  //	异步函数并且无参数
  @bindWithArguments  
  async asyncNoParams() {
    //	fetch
    this.setState({
      xxx: 'xxx'
    });
  }
  
  //	同步函数并且有参数
  @bindWithArguments
  syncParams(id, name) {
    if (id && name) {
      this.setState({
        xxx: 'xxxx'
      });
    }
  }
  
  //	同步函数并且有参数
  @bindWithArguments
  syncNoParams() {
    const { yyy } = this.state;
    if (yyy === 'zzz') {
      this.setState({

      });
    }
  }
  
  
  render() {
    const { list } = this.state;

    return (

          list.map((row) => {
            return (
            	<div className='row' key={row.id}>
              	<button onClick={this.asyncParams(row.id)}>异步函数并且有参数</button>
              	<button onClick={this.syncParams(row.id, row.name)}>同步函数并且有参数</button>
