在ios系统，原生 webview 嵌套H5页面使用时，编写完成的6位数输入密码，输入密码卡顿问题的解决方案：
如下图：
原因是因为，CSS 这块 造成的。简单来说，style left 为负数的时候出现的，android 目测不会出现此问题
input[type=tel] { opacity: 0; z-index: -1; position: absolute; left:-100%; }
解决方案：
重新设置 input样式问题
input[type=tel] { width: 0.1px; height: 0.1px; color: transparent; position: relative; top: 23px; background: #000000; left: 46px; border: none; font-size: 18px; opacity: 0; z-index: -1; }
全部代码在这，你可以拿出去使用即可
<template> <div> <header>支付密码设置</header> <input ref="pwd" type="tel" maxlength="6" v-model="msg" unselectable="on" /> <ul @click="focus"> <li :class="msg.length == 0?'psd-blink':''"><i v-if="msg.length > 0"></i></li> <li :class="msg.length == 1?'psd-blink':''"><i v-if="msg.length > 1"></i></li> <li :class="msg.length == 2?'psd-blink':''"><i v-if="msg.length > 2"></i></li> <li :class="msg.length == 3?'psd-blink':''"><i v-if="msg.length > 3"></i></li> <li :class="msg.length == 4?'psd-blink':''"><i v-if="msg.length > 4"></i></li> <li :class="msg.length == 5?'psd-blink':''"><i v-if="msg.length > 5"></i></li> </ul> <button type="button" @click="sendCode">获取验证码 lodding</button> </div> </template> <script> import api from "./api"; import "@/js/utils"; //公共方法 export default { components: {}, data() { return { msg: '', } }, created() {}, computed: {}, watch: { msg(curVal) { if(/[^\d]/g.test(curVal)) { this.msg = this.msg.replace(/[^\d]/g, ''); } }, }, methods: { focus() { this.$refs.pwd.focus(); }, sendCode() { //时间 utils.sendCode(event.target); //showLoading utils.view.showLoading(); setTimeout(function() { utils.view.dismissLoading(); }, 5000); } }, mounted() {} } </script> <style lang="less" scoped> #payPwd { height: auto; header { text-align: center; height: 80px; line-height: 90px; text-align: center; } input[type=tel] { width: 0.1px; height: 0.1px; color: transparent; position: relative; top: 23px; background: #000000; left: 46px; border: none; font-size: 18px; opacity: 0; z-index: -1; } //光标 .psd-blink { display: inline-block; background: url("./img/blink.gif") no-repeat center; } .pwd-wrap { width: 90%; height: 50px; padding-bottom: 1px; margin: 0 auto; background: #fff; border: 1px solid #ddd; display: flex; display: -webkit-box; display: -webkit-flex; cursor: pointer; position: absolute; left: 0; right: 0; top: 13%; z-index: 10; li { list-style-type: none; text-align: center; line-height: 50px; -webkit-box-flex: 1; flex: 1; -webkit-flex: 1; border-right: 1px solid #ddd; &:last-child { border-right: 0; } i { height: 10px; width: 10px; border-radius: 50%; background: #000; display: inline-block; } } } button { position: relative; display: block; height: 41px; text-align: center; margin: 0 auto; margin-top: 70%; padding: 0 20px; border-radius: 5px; font-size: 16px; border: 1px solid #dddddd; background: #dddddd; color: #000000; } } </style>
附加：如果不想使用光标，直接
//去掉 :class="msg.length == 0?'psd-blink':''" 即可 <li><i v-if="msg.length > 0"></i></li>
