本文主要介紹了用React加CSS3實現微信拆紅包動畫效果，微信紅包曾經引爆過一系列的營銷熱潮，相信大家對於這种红包形式並不陌生，這裡本著娛樂至上的精神用React簡單地實現了拆紅包的動畫效果，希望能幫助大家。

用CSS3繪製紅包

.redpack {
  height: 450px;
  background: #A5423A;
  width: 300px;
  left: 0;
  top: 0;
  border-radius: 10px;
  margin: 0 auto;
}
.topcontent {
    height: 300px;
    border: 1px solid #BD503A;
    background-color: #BD503A;
    border-radius: 10px 10px 50% 50% / 10px 10px 15% 15%;
    box-shadow: 0px 4px 0px -1px rgba(0,0,0,0.2);
}
#redpack-open {
    width: 100px;
    height: 100px;
    border: 1px solid #FFA73A;
    background-color: #FFA73A;
    border-radius: 50%;
    color: #fff;
    font-size: 20px;
    display: inline-block;
    margin-top: -50px;
    box-shadow: 0px 4px 0px 0px rgba(0, 0, 0, 0.2);
}

<p>
  <!--  红包的顶部盖子 -->
  </p><p></p>
  <!-- 拆红包的按钮 -->
  <p></p>

效果如圖：

用React來區分不同的狀態的轉換

############# #用React.js來實現的話，主要透過判斷state來控制紅包現在是等待拆開還是已經拆開過，具體的程式碼如下###

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 (
                <p>
                    </p><p>
                        </p><p>
                            </p><p>
                              </p><p>
                                <img  alt="實例詳解用React加CSS3實現微信拆紅包動畫效果" >
                              </p>
                            
                            <h2 id="奖励">奖励</h2>
                            <span>点击下方按钮领取红包</span>
                            <p>恭喜发财 大吉大利</p>
                        

                        <p>
                            <span>拆红包</span>
                        </p>
                    
                
            );
        } else if (bonus == 0) {
            // 谢谢参与
            return (
                <p>
                    </p><p>
                        </p><p>
                            </p><p>
                                <span></span>
                            </p>
                            <h1 id="谢谢参与"> 谢谢参与 </h1>
                            <span>多多参与的奖励的机会更多哦</span>
                            <br>
                            <a>
                                去我的账户查看
                            </a>
                        

                        <p>
                          </p><p>
                            <img  alt="實例詳解用React加CSS3實現微信拆紅包動畫效果" >
                          </p>
                        
                    
                
            );
        } else {
            // 显示奖励金额
            return (
                <p>
                    </p><p>
                        </p><p>
                            </p><p>
                                <span></span>
                            </p>
                            <h1 id="bonus-toFixed"> {bonus.toFixed(2)} </h1>
                            <span>奖励积分已经存入您的账户</span>
                            <a>
                                去我的账户查看积分
                            </a>
                        

                        <p>
                          </p><p>
                            <img  alt="實例詳解用React加CSS3實現微信拆紅包動畫效果" >
                          </p>
                        
                    
                
            );
        }
    }

    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;
