uni-app 自定义支付密码键盘

1.新建组件 payKeyboard .vue

<template><view class="page-total" v-show="isShow"><view class="key-list"><view class="list" v-for="(item,index) in keyList" :class="{'special':item.keyCode==190||item.keyCode==8,'payMoney':item.keyCode==88}"@click="onKeyList(item,index)":key="item.keyCode"><text>{{item.key}}</text></view></view></view>
</template><script>export default {data() {return {isShow: false,keyList: [{key: 1,en: '',keyCode: 49,},{key: 2,en: 'ABC',keyCode: 50,},{key: 3,en: 'ABC',keyCode: 51,},{key: 4,en: 'ABC',keyCode: 52,},{key: 5,en: 'ABC',keyCode: 53,},{key: 6,en: 'ABC',keyCode: 54,},{key: 7,en: 'ABC',keyCode: 55,},{key: 8,en: 'ABC',keyCode: 56,},{key: '删除',en: 'Del',keyCode: 8,},{key: 9,en: 'ABC',keyCode: 57,},{key: 0,en: 'ABC',keyCode: 48,},{key: '确定',en: 'Pay',keyCode: 88,},],keyIndex: -1,};},props:{passwrdType: {type: String,default: 'pay'}},methods:{show(){this.isShow = true;},hide(){this.isShow = false;},/*** 密码键盘按下* @param {Object} item* @param {Number} index*/onKeyList(item,index){let KeyInfo = item;	// 删除键if(KeyInfo.keyCode === 8 && this.keyIndex > -1){this.keyIndex--;}// 不是删除键if(KeyInfo.keyCode != 8){if(this.passwrdType == 'pay' && this.keyIndex >= 5){console.log('键盘');this.keyIndex = -1;return;}else{this.keyIndex = -1;}this.keyIndex++;}KeyInfo.index = this.keyIndex;this.$emit('KeyInfo',KeyInfo);}}}
</script><style scoped lang="scss">.page-total{position: fixed;left: 0;bottom: 0;width: 100%;z-index:99999;background-color: #f6f6f6;
}.key-list{display: flex;flex-wrap: wrap;align-items: center;padding: 1% 3%;height: 90%;margin-top: 20rpx;.list{display: flex;align-items: center;justify-content: center;width: 32%;height: 92rpx;background-color: #FFFFFF;border-radius: 10rpx;box-shadow: 0 0 10rpx rgba(0,0,0,0.1);margin-right: 1.7%;margin-bottom: 16rpx;text{font-size: 38rpx;font-weight: bold;color: #222222;}}.list:nth-child(3n){margin-right: 0;}.special{background-color: #f6f6f6;box-shadow: none;text{color: #959595;}}.payMoney{background:#F4CA11;text{color: #fff;}}
}
</style>
