用户搜索时,记录用户搜索的历史记录,倒序排列,点击对应的搜索记录文字,也能进行搜索。效果如下图:
- <script>
- export default {
- data() {
- return {
- historyLIst:[],
- productNames:["测试1","测试2","测试3","测试4","测试5","测试6"]
- }
- },
- onLoad() {
- //进入搜索页面时将存储在本地的历史记录取出并展示
- let history = uni.getStorageSync("history");
- if(history){
- this. historyList = JSON.parse(history);
- console.log(this.historyList)
- }
- },
- methods: {
- doSearch(searchStr){//用户搜索时将搜索文字存储
- this.historyList = this.historyList.concat(searchStr);//将搜索内容存储在Array中
- this.historyList = Array.from(new Set(this.historyList.reverse()));//反转数组及去除数组中的重复搜索的相同文字
- if(this.historyList.length>6){
- this.historyList = this.historyList.slice(0,6);//设置展示的历史搜索记录的个数
- }
- uni.setStorageSync("history",JSON.stringify(this.historyList));//将历史记录存储在本地localStorage中
- }
- }
- }
- </script>
