用React来区分不同的状态的转换

用React.js来实现的话,主要通过判断state来控制红包现在是等待拆开还是已经拆开过,具体的代码如下

import React from 'react';

class ReadPacket extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            animation: false,
            status: 0  // 0: 等待拆开 1: 拆开后
        };
    }

    render() {
        var bonus = this.props.thanks ? 0 : parseFloat(this.props.surveyInfo.bonus);

        if(this.state.status == 0) {
            return (
                
                    
                        
                            
                              
                                
                              
                                                         奖励                             点击下方按钮领取红包                             恭喜发财 大吉大利                                                                               拆红包                                                                            );         } else if (bonus == 0) {             // 谢谢参与             return (                                                                                                                                                                                        谢谢参与                              多多参与的奖励的机会更多哦                             
                                                             去我的账户查看                                                                                                                                                                                                                                              );         } else {             // 显示奖励金额             return (                                                                                                                                                                                        {bonus.toFixed(2)}                              奖励积分已经存入您的账户                                                              去我的账户查看积分                                                                                                                                                                                                                                              );         }     }     stopAnimation() {         this.setState({animation: false});     }     showResult() {         this.setState({status: 1});     }     openRedPacket() {         this.setState({animation: true});         setTimeout(this.stopAnimation.bind(this), 3000);         setTimeout(this.showResult.bind(this), 4000);     }     _toWallet() {       // 跳转到钱包       window.location.hash = '/wallet';     } } export default ReadPacket;
