本文主要是介绍uniapp获取键盘高度顶起底部输入框，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
核心代码：
uni.onKeyboardHeightChange((res) => {console.log(res.height);//转化为rpxthis.KeyHight = res.height;});全部代码：
<template><view class="pagesone" :class="'bg-'+themeColor.name" style="padding-top: 100rpx;"><view class="searchdemo" :style="{bottom:KeyHight?KeyHight+'px':KeyHight}" style="display: flex;flex-direction: row;"><view class="input" :class="'input-'+themeColor.name"><view class="icon"><image class="icon-child" :src="'/static/search-'+themeColor.name+'.png'" /></view><input :adjust-position="false" :always-system="true" :value="searchContent" confirm-type="search" @confirm="search" @input="onInputSearch":class="'text-'+themeColor.name" class="input-text" placeholder="输入股票名称/缩写/代码"placeholder-class="placeholder-class" :focus="true"></input><view class="icon" v-show="this.searchContent!=''" @click="clearSearch()"><image class="icon-child" :src="'/static/delete.png'" /></view></view><text :class="'text-'+themeColor.name" @click="back"style="font-size: 32rpx;margin-top: 15rpx;margin-left: 20rpx;">取消</text></view><!-- <view style="margin-top: 30rpx; display: flex;flex-direction: row;justify-content: center;"><text :class="'text-'+themeColor.name" style="font-size: 28rpx;" v-show="tab == 1"@click="ChangeTab(1)">股票</text><text style="font-size: 28rpx;color: #6F6F6F;" v-show="tab != 1" @click="ChangeTab(1)">股票</text><text :class="'text-'+themeColor.name" style="font-size: 28rpx;margin-left: 130rpx;margin-right: 130rpx;"v-show="tab == 2" @click="ChangeTab(2)">概念</text><text style="font-size: 28rpx;color: #6F6F6F;margin-left: 130rpx;margin-right: 130rpx;" v-show="tab != 2"@click="ChangeTab(2)">概念</text><text :class="'text-'+themeColor.name" style="font-size: 28rpx;" v-show="tab == 3"@click="ChangeTab(3)">资讯</text><text style="font-size: 28rpx;color: #6F6F6F;" v-show="tab != 3" @click="ChangeTab(3)">资讯</text></view> --><view class="blist" :style="{bottom:KeyHight?KeyHight+40+'px':'80rpx'}" style="padding-top: 30rpx;" v-show="tab == 1"><block v-for="(item, index) in gpList.slice().reverse()" :key="index"><u-GPList :item="item"></u-GPList></block></view><view :class="'bg-'+themeColor.name" style='position: fixed;width:100%;height: 100%;z-index: 0;'></view></view></template><script>import uGPList from './search-main-gupiao-list.vue';export default {components: {uGPList,},data() {return {tab: 1,searchContent: "",gpList: [],KeyHight: 0,}},onLoad(option) {this.$statusColor.modification();uni.onKeyboardHeightChange((res) => {console.log(res.height);//转化为rpxthis.KeyHight = res.height;});},methods: {back() {uni.navigateBack({});},clearSearch() {this.searchContent = "";},ChangeTab(tab) {this.tab = tab;},/* 键盘上完成(回车)的事件 */search() {if (this.isBlank(this.searchContent)) {this.$toast("输入股票代码/首字母");return;}if (this.tab == 1) {this.search_index(this.searchContent);} else if (this.tab == 2) {} else if (this.tab == 3) {}},onInputSearch: function(e) {if (this.tab == 1) {this.searchContent = e.detail.value;if (this.searchContent != "") {this.search_index(this.searchContent);}} else if (this.tab == 2) {} else if (this.tab == 3) {}},search_index(word) {var _this = this;this.request({urlInfo: this.$REQUEST.SEARCH_INDEX,body: {word: word,showtype: 'app',},success(res) {console.log("search_index==", res)},fail: (res) => {console.log("search_index==", res)var newList = [];res.data.data.filter((item, i) => {var obj = {};var sList = item.split(" ")obj.code = sList[0];obj.name = sList[1];obj.sx = sList[2];obj.foxxcode = sList[3];newList[i] = obj;return item >= res.data.data.length})_this.gpList = newList;}})},},}
</script><style lang="scss">
.pagesone{width: 100%;height: 100%;
}
.searchdemo{//触底width: 100vw;position: absolute;bottom: 0;z-index: 99;//被键盘顶起
}
.blist{width: 100vw;position: absolute;bottom: 80rpx;z-index: 99;
}.icon {.icon-child {width: 40rpx;height: 40rpx;margin-top: 10rpx;}}.input {margin-left: 30rpx;width: 75%;height: 76rpx;display: flex;flex-direction: row;align-items: center;border-radius: 10rpx;padding-left: 20rpx;padding-right: 20rpx;}.input-text {margin-left: 20rpx;margin-right: 20rpx;width: 100%;font-size: 32rpx;}.placeholder-class {color: #6F6F6F;font-size: 32rpx;}
</style>
此方法适配ios和安卓
