设计支付密码的输入框

效果如下：

实例代码：<view>index.jsPage({ data: {payment_mode: 1,//默认支付方式 微信支付isFocus: false,//控制input 聚焦balance:100,//余额actual_fee:20,//待支付wallets_password_flag:false//密码输入遮罩 }, //事件处理函数onLoad: function () {}, wx_pay() {//转换为微信支付this.setData({payment_mode: 1}) }, offline_pay() {//转换为转账支付this.setData({payment_mode: 0}) }, wallet_pay() {this.setData({//转换为钱包支付payment_mode: 2}) }, set_wallets_password(e) {//获取钱包密码this.setData({wallets_password: e.detail.value});if (this.data.wallets_password.length == 6) {//密码长度6位时，自动验证钱包支付结果wallet_pay(this)} }, set_Focus() {//聚焦inputconsole.log('isFocus', this.data.isFocus)this.setData({isFocus: true}) }, set_notFocus() {//失去焦点this.setData({isFocus: false}) }, close_wallets_password () {//关闭钱包输入密码遮罩this.setData({isFocus: false,//失去焦点wallets_password_flag: false,}) }, pay() {//去支付pay(this) }})/*-----------------------------------------------*//*支付*/function pay(_this) { let apikey = _this.data.apikey; let id = _this.data.id; let payment_mode = _this.data.payment_mode if (payment_mode == 1) { // 微信支付 // 微信自带密码输入框console.log('微信支付') } else if (payment_mode == 0) { // 转账支付 后续跳转至传转账单照片console.log('转账支付') } else if (payment_mode == 2) {// 钱包支付 输入密码console.log('钱包支付')_this.setData({wallets_password_flag: true,isFocus: true}) }}// 钱包支付function wallet_pay(_this) { console.log('钱包支付请求函数') /* 1.支付成功 2.支付失败：提示；清空密码；自动聚焦isFocus:true，拉起键盘再次输入 */}index.wxsspage { height: 100%; width: 100%; background: #e8e8e8;}page .pay { display: flex; flex-direction: column; background: #fff;}page .pay .title { height: 90rpx; line-height: 90rpx; font-size: 28rpx; color: #353535; padding: 0 23rpx; border-bottom: 1rpx solid #ddd; box-sizing: border-box;}page .pay .wx_pay, page .pay .offline_pay, page .pay .wallet_pay { margin: 0 26rpx; height: 90rpx; line-height: 90rpx; border-bottom: 2rpx solid #ddd; box-sizing: border-box; display: flex; align-items: center; justify-content: flex-start;}page .pay .wx_pay .icon, page .pay .offline_pay .icon,page .pay .wallet_pay .icon { width: 34rpx; height: 34rpx; border: 2rpx solid #ddd; box-sizing: border-box; border-radius: 50%;}page .pay .wx_pay .icon.active, page .pay .offline_pay .icon.active,page .pay .wallet_pay .icon.active { border: 10rpx solid #00a2ff;}page .pay .wx_pay text, page .pay .offline_pay text, page .pay .wallet_pay text { margin-left: 20rpx; color: #353535; font-size: 26rpx;}page .pay .wallet_pay { border: 0; border-top: 2rpx solid #ddd;}page .pay .offline_pay { border: 0 none;}page .save { margin: 80rpx 23rpx; color: #fff; background: #00a2ff; height: 88rpx; line-height: 88rpx; text-align: center; font-size: 30rpx; border-radius: 10rpx;}page .wallets-password { position: absolute; left: 0; top: 0; width: 100%; height: 100%; background: rgba(0, 0, 0, 0.6);}page .wallets-password .input-content-wrap { position: absolute; top: 200rpx; left: 50%; display: flex; flex-direction: column; width: 600rpx; margin-left: -300rpx; background: #fff; border-radius: 20rpx;}page .wallets-password .input-content-wrap .top { display: flex; align-items: center; height: 90rpx; border-bottom: 2rpx solid #ddd; justify-content: space-around;}page .wallets-password .input-content-wrap .top .close { font-size: 44rpx; color: #999; font-weight: 100;}page .wallets-password .input-content-wrap .top .forget { color: #00a2ff; font-size: 22rpx;}page .wallets-password .input-content-wrap .actual_fee { display: flex; align-items: center; justify-content: center; color: #000; height: 100rpx; margin: 0 23rpx; border-bottom: 2rpx solid #ddd;}page .wallets-password .input-content-wrap .actual_fee span { font-size: 24rpx;}page .wallets-password .input-content-wrap .actual_fee text { font-size: 36rpx;}page .wallets-password .input-content-wrap .input-password-wrap { display: flex; align-items: center; justify-content: center; height: 150rpx;}page .wallets-password .input-content-wrap .input-password-wrap .password_dot { display: flex; align-items: center; justify-content: center; text-align: center; color: #000; box-sizing: border-box; width: 90rpx; height: 90rpx; border: 2rpx solid #ddd; border-left: none 0;}page .wallets-password .input-content-wrap .input-password-wrap .password_dot:nth-child(1) { border-left: 2rpx solid #ddd;}page .wallets-password .input-content-wrap .input-password-wrap .password_dot i { background: #000; border-radius: 50%; width: 20rpx; height: 20rpx;}page .wallets-password .input-content { position: absolute; opacity: 0; left: -100%; top: 600rpx; background: #f56; z-index: -999;}page .wallets-password .input-content.active { z-index: -99;}以上就是微信小程序实现密码输入的实例的详细内容，更多请关注小潘博客其它相关文章！
