这篇文章主要介绍了微信小程序 密码输入（源码下载）的相关资料,需要的朋友可以参考下

设计支付密码的输入框

效果如下：

实例代码：

 view >
index.js

Page({
 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input
 console.log( #39;isFocus #39;, 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( #39;微信支付 #39;)
 } else if (payment_mode == 0) {
 // 转账支付 后续跳转至传转账单照片
 console.log( #39;转账支付 #39;)
 } else if (payment_mode == 2) {
 // 钱包支付 输入密码
 console.log( #39;钱包支付 #39;)
 _this.setData({
 wallets_password_flag: true,
 isFocus: true
// 钱包支付
function wallet_pay(_this) {
 console.log( #39;钱包支付请求函数 #39;)
 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
