React - ES6 - Ajax获取接口数据渲染到UI组件【完整示例】
[ 2016/09/24 01:22 | by 刘新修 ]
本站PHP后端接口: http://code.liuxinxiu.com/php/Interface/Jsoncallback.php?GUID=1&&Jsoncallback=1
本实例用 ES5 + JSX 语法编写[对应实例] : http://liuxinxiu.com/React_Ajax_setState_Render_UI_ES5/
JavaScript代码
- /****** ES6输入文件[调用模块依赖] ******/
- import React, { Component, PropTypes } from 'react'
- import $ from 'n-zepto'
- /****** ES5输入文件[调用模块依赖] ******/
- //var React=require('react');
- //var $=require('n-zepto');
- //import * as from './commentList.js'
- //import list from './commentList.js';
- /****** 本地模拟Array数据******/
- var movies = [

- date: 2011
- },
- {
- id: 2,
- name: '速度与激情002',

- }
