/**

export const newViewEnum = 99; // 游戏栏目"最近浏览"的ID，是为了选中效果
export function setHistoryList(item) {
    const newViewNum = 8; // 显示历史记录条数
    let HistoryList = [];
    if(window.localStorage.getItem('HistoryList') && window.localStorage.getItem('HistoryList') !== '[""]') {
        let newHistoryList = JSON.parse(window.localStorage.getItem('HistoryList'));
        let newArr = HistoryList.concat(newHistoryList)
        if (newArr.length > 0) {
            newArr.map((vo,key) => {
                if(vo.id === item.id) {
                    newArr.splice(key, 1)
                }
            })
        }
        newArr.unshift(item)
        if (newArr.length > newViewNum) {
            newArr.pop();
        }
        window.localStorage.setItem('HistoryList', JSON.stringify(newArr))
    } else {
        HistoryList.push(item);
        window.localStorage.setItem('HistoryList', JSON.stringify(HistoryList))
    }
}

使用方法：

gotoPage(item) {
    setHistoryList(item);
    this.$router.push({path: '/goodsList'});
},
