使用方法

// 不同的业务功能历史记录设置不同存储key
const kStorageKey = "storageKey"

// 执行搜索事件
doSearch() {
if (this.keyword == '') {
uni.showToast({
title: '请输入要搜索的内容',
icon: 'none'
});
return;
}
//
if (this.keyword && this.keyword !== '') {
this.saveKeyword(this.keyword); //保存为历史
}

uni.showLoading({
title: '搜索中...'
});
this.setData({
keywordList: []
});

uni.hideLoading()
uni.showModal({
title: "温馨提示",
content: '搜索的内容 = ' + this.keyword
})

},

//点击历史记录搜索
doHisSearch(item) {
console.log(item)
uni.showModal({
title: '点击的历史搜索条目',
content: '点击的历史搜索条目 = ' + item
})
},
