用CSS3繪制紅包
.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); }
<div class='redpack'> <!-- 紅包的頂部蓋子 --> <div class="topcontent"></div> <!-- 拆紅包的按鈕 --> <div id="redpack-open"></div> </div>
效果如圖:
用React來(lái)區(qū)分不同的狀態(tài)的轉(zhuǎn)換
用React.js來(lái)實(shí)現(xiàn)的話,主要通過(guò)判斷state來(lái)控制紅包現(xiàn)在是等待拆開(kāi)還是已經(jīng)拆開(kāi)過(guò),具體的代碼如下
import React from 'react'; class ReadPacket extends React.Component { constructor(props) { super(props); this.state = { animation: false, status: 0 // 0: 等待拆開(kāi) 1: 拆開(kāi)后 }; } render() { var bonus = this.props.thanks ? 0 : parseFloat(this.props.surveyInfo.bonus); if(this.state.status == 0) { return ( <div className='redpack-container' id='redpack-container'> <div className='redpack'> <div className='topcontent'> <div id='redpack-opened'> <div className='redpack-avatar'> <img src='http://placehold.it/80x80' alt='頭像' width='80' height='80'/> </div> </div> <h3 style={{marginTop: 80, color: 'white'}}>獎(jiǎng)勵(lì)</h3> <span className='redpack-text'>點(diǎn)擊下方按鈕領(lǐng)取紅包</span> <div className='redpack-description white-text'>恭喜發(fā)財(cái) 大吉大利</div> </div> <div id='redpack-open' className={this.state.animation ? 'rotate' : ''} onClick={this.openRedPacket.bind(this)} > <span>拆紅包</span> </div> </div> </div> ); } else if (bonus == 0) { // 謝謝參與 return ( <div className='redpack-container' id='redpack-container'> <div className='redpack'> <div className='topcontent-open'> <div className='redpack-avatar'> <span id='close'></span> </div> <h2 style={{marginTop: 180, color: 'white'}}> 謝謝參與 </h2> <span className='redpack-text'>多多參與的獎(jiǎng)勵(lì)的機(jī)會(huì)更多哦</span> <br/> <a onClick={this._toWallet.bind(this)} style={{cursor:'pointer',textDecoration: 'underline', color: 'white'}}> 去我的賬戶(hù)查看 </a> </div> <div id='redpack-opened'> <div className='redpack-avatar'> <img src='http://placehold.it/80x80' alt='頭像' width='80' height='80'/> </div> </div> </div> </div> ); } else { // 顯示獎(jiǎng)勵(lì)金額 return ( <div className='redpack-container' id='redpack-container'> <div className='redpack'> <div className='topcontent-open'> <div className='redpack-avatar'> <span id='close'></span> </div> <h2 className='white-text' style={{marginTop: 180}}> {bonus.toFixed(2)} </h2> <span className='redpack-text'>獎(jiǎng)勵(lì)積分已經(jīng)存入您的賬戶(hù)</span> <a className='btn-flat white-text' onClick={this._toWallet.bind(this)} style={{textDecoration: 'underline'}}> 去我的賬戶(hù)查看積分 </a> </div> <div id='redpack-opened'> <div className='redpack-avatar'> <img src='http://placehold.it/80x80' alt='頭像' width='80' height='80'/> </div> </div> </div> </div> ); } } 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() { // 跳轉(zhuǎn)到錢(qián)包 window.location.hash = '/wallet'; } } export default ReadPacket;
