Answer 1

我希望这能帮助你：

  var categorydata = [
        { category_id: 2, name: "Default Category", position: 1 },
        { category_id: 3, name: "Clothing", position: 14597 },
        { category_id: 6, name: "Brands", position: 1 },
        { category_id: 8, name: "What's New", position: 1011 },
        { category_id: 12, name: "Dresses", position: 4456 },
        { category_id: 128, name: "Current Mood", position: 189 },
        { category_id: 138, name: "Mini", position: 13078 },
        { category_id: 630, name: "Kandi - Rave Clothing", position: 264 },
        { category_id: 1130, name: "Char Test Category", position: 99 },
        { category_id: 2443, name: "Sets", position: 163 },
        { category_id: 2657, name: "Club Exx Festival", position: 208 }
    
    ];
    var allcategorydatawithlevel = [
        { id: 1, level: 1 },
        { id: 2, level: 5 }
    ]

  var category = [];
    
    for (i = 0; i < allcategorydatawithlevel.length; i++) {
        for (x = 0; x < categorydata.length; x++) {
            if (allcategorydatawithlevel[i].id == categorydata[x].category_id) {
                category.push(allcategorydatawithlevel[i].level);
            }
        }
    }
    localStorage.setItem("category", JSON.stringify(category));
    console.log(JSON.stringify(category));

您还可以使用以下代码：

  allcategorydatawithlevel.forEach((item, index) => {
        categorydata.forEach((key, val) => {
            if (item.id === key.category_id) {
                category.push(item.level);
            }
        })
        localStorage.setItem("category", JSON.stringify(category));

    })
    console.log(JSON.stringify(category));
