怎么在微信小程序中實現發送驗證碼按鈕效果?相信很多沒有經驗的人對此束手無策,為此本文總結了問題出現的原因和解決方法,通過這篇文章希望你能解決這個問題。
實現關鍵點
獲取驗證碼按鈕無邊框: 可以用 button::after{ border: none; } 來去除邊框,或者直接用view綁定點擊事件。本例子中沒有使用button
點擊發送后,60秒內按鈕處于disable狀態
點擊發送后,text分為剩余秒數和后綴兩部分
.form_group 使用 flex 布局
代碼
.wxml
<view class="form_group"> <input type="text" placeholder="手機號碼" placeholder-class="placeholder_style" data-name="data_phone" value="{{data_phone}}" bindinput='getInputKey' /> </view> <view class="form_group"> <input type="text" class="sendmsg_input" placeholder="短信驗證碼" data-name="data_code" value="{{data_code}}" placeholder-class="placeholder_style" bindinput='getInputKey' /> <view class='vertificate' bindtap="getVerificationCode">{{time}} <text>{{suffix}}</text> </view> </view>
.wxss
.form_group { display: flex; flex-direction: row; justify-content: space-between; } .form_group input, .form_group picker { width: 676rpx; border-bottom: 1px solid #ddd; height: 121rpx; padding-left: 20rpx; font-family: PingFangSC-Regular; font-size: 32rpx; letter-spacing: 0; line-height: 121rpx; } .form_group .sendmsg_input { width: 370rpx; } .form_group .vertificate { width: 326rpx; border-bottom: 1px solid #ddd; height: 121rpx; padding-left: 20rpx; font-family: PingFangSC-Regular; font-size: 32rpx; letter-spacing: 0; line-height: 121rpx; text-align: center; color: #34c9c3; } .vertificate text { color: gray; } .placeholder_style { font-family: PingFangSC-Regular; font-size: 32rpx; color: #dbdbdb; letter-spacing: 0; }
.js
import SignupService from '../service/sign-up.service.js'; import HTTP from '../../../utils/http.js'; import Util from '../../../utils/util.js'; let _signupService = new SignupService(); let _http = new HTTP(); let _util = new Util(); Page({ data: { time: "獲取驗證碼", currentTime: 61, disabled:false, suffix:'', data_phone:'', data_code:'', }, ... // 獲取輸入框的值 getInputKey(e) { let key = e.currentTarget.dataset.name; let value = e.detail.value; this.setData({ [key]: value }) }, // 獲取驗證碼 getVerificationCode() { let _this = this; if (!_this.data.disabled) { _this.getCode(); } }, getCode() { let _this = this; let phone = _this.data.data_phone; if (_util.isPhoneAvailable(phone)) { _signupService.getCode(phone).then(res=>{ // 調用后端API,獲取手機驗證碼 _util.showToast('success',"已發送"); _this.setData({ disabled: true }) },err=>{ _util.showToast('none',"發送失敗") }); // 設置發送驗證碼按鈕樣式 let interval = null; let currentTime = _this.data.currentTime; interval = setInterval(function() { currentTime--; _this.setData({ time: currentTime, suffix: '秒后可重新獲取' }) if (currentTime <= 0) { clearInterval(interval) _this.setData({ time: '重新發送', suffix: '', currentTime: 61, disabled: false }) } }, 1000) } else { _util.showToast('none','請輸入正確的手機號碼。'); } },
sign-up.service.js
//獲取手機驗證碼 getCode(phone){ return _http.request({ type: 'post', url: '/account/validate-codes', data: { phone:phone } }) }
http.js: 封裝wx.request 為Promise
class HTTP { request(param){ let _this = this; let baseUrl = '.......'; return new Promise((resolve, reject) => { let access_token = wx.getStorageSync('access_token'); wx.request({ method: param.type || 'get', url: baseUrl+ param.url || '', data: param.data || null, header: access_token ? { 'content-type': 'application/x-www-form-urlencoded', "Authorization": `Bearer ${access_token}` } : { 'content-type': 'application/x-www-form-urlencoded', }, success: (res => { if (res.statusCode === 200 || res.statusCode === 201) { //200: 服務端業務處理正常結束 resolve(res.data) } else { //其它錯誤,提示用戶錯誤信息 /*** * 需要根據接口文檔改!!! */ reject(res) } }), fail: (err => { if(err.responseJSON){ reject(err.responseJSON.message) }else{ reject(err); } }) }); }); } } export default HTTP;
util.js
// 驗證手機號碼是否有效 isPhoneAvailable(phone) { var myreg = /^[1][3,4,5,7,8][0-9]{9}$/; if (!myreg.test(phone)) { return false; } else { return true; } } //小程序彈框提示 showToast(icon,msg,duration=2000){ wx.showToast({ title: msg, duration: duration, icon: icon }) }
