uniapp简单实现搜索--历史记录功能

点击搜索时候，将搜索的值存入本地记录并展示，并且有清空历史记录功能。

代码直接贴上：

<template>
	<view>
		<!-- 搜索框 -->
		<view class="search">
			<view style="display: flex;align-items: center;">
				<text class="iconfont icon-sousuo position-absolute text-muted"></text>
				<input class="searchInput" v-model="inputValue" @confirm="search" placeholder="搜索" type="text" />
			</view>
			<view>取消</view>
		</view>
		<!-- 搜索框 -->

		<!-- 搜索历史 -->
		<view class="searchHistory">
			<view style="display: flex;align-items: center;justify-content: space-between;box-sizing: border-box;padding: 0px 5px;">
				<view>搜索历史:</view>

				<view style="color: red;font-size: 28px;" @click="empty">×</view>
			</view>
			<view class="searchHistoryItem">
				<view v-for="(item, index) in searchHistoryList" :key="index">
					<text>{{ item }}</text>
				</view>
			</view>
		</view>
		<!-- 搜索历史 -->
	</view>
</template>

<script>
export default {
	data() {
		return {
			inputValue: '',
			searchHistoryList: [] //搜索出来的内容
		};
	},
	methods: {
		search() {
			if (this.inputValue == '') {
				uni.showModal({
					title: '搜索内容不能为空'
				});
			} else {
				if (!this.searchHistoryList.includes(this.inputValue)) {
					this.searchHistoryList.unshift(this.inputValue);
					uni.setStorage({
						key: 'searchList',
						data: JSON.stringify(this.searchHistoryList)
					});
				} else {
					//有搜索记录，删除之前的旧记录，将新搜索值重新push到数组首位
					let i = this.searchHistoryList.indexOf(this.inputValue);
					this.searchHistoryList.splice(i, 1);
					this.searchHistoryList.unshift(this.inputValue);
					uni.showToast({
						title: '不能重复添加'
					});
					uni.setStorage({
						key: 'searchList',
						data: JSON.stringify(this.searchHistoryList)
					});
				}
			}
		},
		//清空历史记录
		empty() {
			uni.showToast({
				title: '已清空'
			});
			uni.removeStorage({
				key: 'searchList'
			});

			this.searchHistoryList = [];
		}
	},
	async onLoad() {
		let list = await uni.getStorage({
			key: 'searchList'
		});
		// console.log(list,'历史记录----');
		if(list[1]&&list[1].data.length>0){			
	    	this.searchHistoryList = JSON.parse(list[1].data);
		}

		
	}
};
</script>
