Append (key value) data to existing data in localstorage using jquery

Question

I am trying to compare two id's and append a property into existing local storage data. in for loop.

Here is the codepen that shows the sample data & logic.

Simply I am trying to check the id of var allcategorydatawithlevel with categorydata of var category_id & if these two match I want to append level property of the allcategorydatawithlevel to categorydata. Please take a look at the Codepen it contains data sample & logic which I have tried.

Your objects (or array with objects) seem to copied and pasted from the console and therefore they are syntactically incorrect. Please fix your code and make it run without errors. — Emiel Zuurbier, Aug 04 '20 at 05:53

I hope this help you :

  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));

You can also use below code :

  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));

Let me check the above answer for the question. – Aug 04 '20 at 06:54 — , Aug 04 '20 at 06:54
