這次帶給大家React與CSS3實作微信拆紅包動畫，React與CSS3實作微信拆紅包動畫的注意事項有哪些，以下就是實戰案例，一起來看一下。

微信紅包曾經引爆過一系列的行銷熱潮，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，供大家一起交流學習

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 class=&#39;redpack&#39;>
  <!--  红包的顶部盖子 -->
  <p class="topcontent"></p>
  <!-- 拆红包的按钮 -->
  <p id="redpack-open"></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 className=&#39;redpack-container&#39; id=&#39;redpack-container&#39;>
                    <p className=&#39;redpack&#39;>
                        <p className=&#39;topcontent&#39;>
                            <p id=&#39;redpack-opened&#39;>
                              <p className=&#39;redpack-avatar&#39;>
                                <img src=&#39;http://placehold.it/80x80&#39; alt=&#39;头像&#39; width=&#39;80&#39; height=&#39;80&#39;/>
                              </p>
                            </p>
                            <h2 style={{marginTop: 80, color: &#39;white&#39;}}>奖励</h2>
                            <span className=&#39;redpack-text&#39;>点击下方按钮领取红包</span>
                            <p className=&#39;redpack-description white-text&#39;>恭喜发财 大吉大利</p>
                        </p>
                        <p id=&#39;redpack-open&#39; className={this.state.animation ? &#39;rotate&#39; : &#39;&#39;}
                             onClick={this.openRedPacket.bind(this)}
                        >
                            <span>拆红包</span>
                        </p>
                    </p>
                </p>
            );

                            <h1 style={{marginTop: 180, color: &#39;white&#39;}}> 谢谢参与 </h1>
