这篇文章主要为大家详细介绍了微信小程序实现接收验证码,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了微信小程序实现接收验证码的具体代码,供大家参考,具体内容如下
效果如下图:
wxml部分如下:
<!--验证码--> <view class="mod t-name" style='position:relative'> <text class="key">验证码:</text> <input type="digit" bindinput="bindKeyInput" data-inputname="phoneCode" value='{{phoneCode}}' class="input" maxlength="100" placeholder="请输入手机验证码" /> <text class='logbook'></text> <text class='getkey' bindtap="clickGainCode">{{tipsCode}}</text> </view>
css部分代码如下:
.mod{ display: flex; flex-direction: row; justify-content: space-between; align-items: center; height: 100rpx; padding: 0 20rpx; border-bottom:1rpx solid #ccc; box-sizing: border-box; } .mod .key{ font-size: 28rpx; font-weight: bold; text-align: right; width: 160rpx; } .t-name{ background-color: rgb(254,254,254); box-sizing: border-box; } .t-name .input{ width: 540rpx; font-size: 28rpx; margin-left: 30rpx; } .logbook { font-size: 24rpx; width: 150rpx; text-align: right; font-weight: bold; } .getkey { width: 200rpx; position: absolute; right: 0rpx; text-align: center; color: rgb(31, 45, 210); font-size: 24rpx; border-left: 1px solid #f0f0f0; }
js的data里定义如下内容:
data: { tipsCode: "获取验证码", timeNum: 60, clikType: false, phone: null, phoneCode: null, }
获取验证码方法如下:
bindKeyInput: function(e) { this.data[e.currentTarget.dataset.inputname] = e.detail.value; this.setData(this.data); }, //获取验证码时的显示时间 getTime() { var that = this; var timer = setInterval(function() { that.data.timeNum--; if (that.data.timeNum <= 0) { that.setData({ tipsCode: "重新获取验证码", timeNum: timeOut, clikType: false }); clearInterval(timer); } else { that.setData({ tipsCode: "重新发送" + that.data.timeNum + "秒", }) } }, 1000) }, //输入手机号获取验证码 gainCode() { var that = this; if (this.data.phone == '' || this.data.phone == null) { wx.showToast({ title: '手机号不能为空', icon: 'none', }) } else { that.setData({ clikType: true }) if (this.data.timeNum < timeOut) { } else { wx.request({ url: wxapp_api_url + '/common/getCode', header: { 'content-type': 'application/x-www-form-urlencoded' }, method: "get", data: { phone: this.data.phone }, success: function(res) { that.getTime(); } }) } } }, // 点击获取手机验证码 clickGainCode(e) { if (!this.data.clikType) { this.gainCode(); } },
