支付密码功能界面如下图：
主要代码如下：
<template> <div> <div> <span @click="backHandle"></span><strong>请输入交易密码</strong> </div> <div> <div> <div v-for="i in items"><span v-if="password[i]"></span></div> </div> <div><router-link to="/getP">忘记密码？</router-link></div> </div> <div> <ul> <li @click="keyUpHandle($event)" v-for="val in keys"> {{ val }} </li> <li @click="delHandle"><span><</span></li> </ul> </div> </div> </template> <script> const keys = () => [1, 2, 3, 4, 5, 6, 7, 8, 9, '', 0] // let sendFlag = true // 防止重复发送密码 export default { data () { return { items: [0, 1, 2, 3, 4, 5], keys: keys(), password: [] } }, methods: { backHandle () { this.clearPasswordHandle() // 返回时清除password this.$emit('backFnc') // 返回上级 }, keyUpHandle (e) { let text = e.currentTarget.innerText let len = this.password.length if (!text || len >= 6) return this.password.push(text) this.ajaxData() }, delHandle () { if (this.password.length <= 0) return false this.password.shift() }, ajaxData () { if (this.password.length >= 6) { console.log(parseInt(this.password.join(' ').replace(/\s/g, ''))) } return false }, clearPasswordHandle: function () { this.password = [] } } } </script> <style lang="less" scoped> .pay-tool { position: relative; height: 18.93333333rem; background-color: #fff; overflow: hidden; &-title { width: 100%; height: 2.08888888rem; padding: 0 0.8rem; line-height: 2.08888888rem; text-align: center; overflow: hidden; .icon { float: left; margin-top: 0.72222222rem; } strong { font-size: 0.8rem; } } &-content { .pay-tool-inputs { width: 14.46666666rem; height: 2.31111111rem; margin: 1.28888888rem auto 0; border: 1px solid #b9b9b9; border-radius: 0.26666666rem; box-shadow: 0 0 1px #e6e6e6; display: flex; .item { width: 16.66666666%; height: 2.31111111rem; border-right: 1px solid #b9b9b9; line-height: 2.31111111rem; text-align: center; &:last-child { border-right: none; } .icon_dot { display: inline-block; width: 0.51111111rem; height: 0.51111111rem; background: url("../../assets/images/icon_dot.png") no-repeat; background-size: cover; } } } .pay-tool-link { padding: 0.53333333rem 0.8rem 0; text-align: right; .link { font-size: 0.66666666rem; color: #3c8cfb; } } } .pay-tool-keyboard { position: absolute; left: 0; bottom: 0; width: 100%; ul { width: 100%; display: flex; flex-wrap: wrap; li { width: 33.3333%; height: 2.25442834rem; line-height: 2.25442834rem; text-align: center; border-right: 1px solid #aeaeae; border-bottom: 1px solid #aeaeae; font-size: 0.8rem; font-weight: bold; &:nth-child(1), &:nth-child(2), &:nth-child(3) { border-top: 1px solid #eee; } &:nth-child(3), &:nth-child(6), &:nth-child(9), &:nth-child(12) { border-right: none; } &:nth-child(10), &:nth-child(11), &:nth-child(12) { border-bottom: none; } &:nth-child(10), &:nth-child(12), &:active { background-color: #d1d4dd; } &:nth-child(12):active { background-color: #fff; } } } } } </style>
注意：页面使用rem布局，根html的font-size为45px。
