IT技术 - 如何在react中打印对象数组 - 吾爱随笔录

我有以下代码

import React, { Component } from 'react'; 从'../ethereum/factory' 导入工厂；

import ads_list from './ads_list'

class showAds extends Component {
  static async getInitialProps(){
    let i;
    let a = [];
    const ad=await factory.methods.getAdress().call();
    const unique_address = Array.from(new Set(ad));
    for ( i = 0 ;i < unique_address.length;i++){
       a[i] = await factory.methods.getClientData(unique_address[i]).call();
    }
   console.log(a);
   return {a};
 }

 render(){
    return <div>
             <p>{}</p>
          </div>;
    }
 }

 export default showAds;

对于上面的代码，我在控制台中得到了低于值。

   [ 
      {
        '0': 'www.google.com', 
        '1': 'Click here and enjoy searching', 
        '2': '17' 
      },
      { 
        '0': 'www.gmail.com', 
        '1': 'PLease login here', 
        '2': '2' 
      } 
      { 
       '0': 'www.google.com',
       '1': 'Click here and enjoy searching',
       '2': '17' 
      },
      { 
       '0': 'www.gmail.com',
       '1': 'PLease login here', 
       '2': '2' 
      } 
    ]

我面临的问题是在前端打印这些值。

class App extends React.Component { render() { const data = [ { "0": "www.google.com", "1": "Click here and enjoy searching", "2": "17" }, ]; return ( <ul> {data.map(item => { return <li>{item[0]}</li>; })} </ul> ); } }
