如何在 HTML 中顯示來自 JS Object 的信息？

Question

我怎樣才能創建這樣的東西：

我已經有這樣存儲的 JS 對象：

var hoodieArray = [{
    type: 'Hoodie',
    color: 'Purple',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (1).jpg'
},
{
    type: 'Hoodie',
    color: 'Light Blue',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (2).jpg'
},
{
    type: 'Hoodie',
    color: 'Green',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (3).jpg'
}]

但我不完全確定如何在產品卡片中顯示它們。 這是我到目前為止所做的：

<style>
    .card {
        box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2);
        max-width: 300px;
        margin: auto;
        text-align: center;
    }

    .price {
        color: grey;
        font-size: 22px;
    }

    .card button {
        outline: 0;
        color: #000000;
        text-align: center;
        font-size: 18px;
    }
</style>

<div class="card">
    <img src="https://img.sonofatailor.com/images/customizer/product/White_O_Crew_Regular_NoPocket.jpg" alt="Denim Jeans" style="width:100%">
    <h1>Tailored Jeans</h1>
    <p>Some text about the jeans..</p>
    <p class="price">$19.99</p>
    <p><button>Add to Cart</button></p>
</div>

顯示：

你會如何處理這個問題？ 因為我希望它們正確地彼此相鄰顯示，並在 JavaScript Object 中提供各自的信息

Answer 1

為此，您需要 javascript。

首先，您需要創建一個容器來包含所有卡片

<div id="hoodiesContainer" style="display: flex; justify-content: space-between; margin: 30px;">

</div>

然后您必須評估hoodieArray以使所有元素顯示在卡片中：

var hoodieArray = [{
    type: 'Hoodie',
    color: 'Purple',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (1).jpg'
},
{
    type: 'Hoodie',
    color: 'Light Blue',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (2).jpg'
},
{
    type: 'Hoodie',
    color: 'Green',
    material: 'cotton authentic',
    price: '£39.99',
    image: 'images/items/hoodies/hoodie (3).jpg'
}]

//Evaluate each hoodie and display its details
    hoodieArray.forEach(function (hoodie) {
        let card = `
        <div class="card">
            <img src="${hoodie.image}" style="width:100%">
            <h1>${hoodie.material}</h1>
            <p>Color: ${hoodie.color}</p>
            <p class="price">${hoodie.price}</p>
            <p><button>Add to Cart</button></p>
        </div>
    `;
        // Add the card to the page
        document.getElementById('hoodiesContainer').innerHTML += card;
    });

放在一起作為一個可運行的片段......

 var hoodieArray = [{ type: 'Hoodie', color: 'Purple', material: 'cotton authentic', price: '£39.99', image: 'images/items/hoodies/hoodie (1).jpg' }, { type: 'Hoodie', color: 'Light Blue', material: 'cotton authentic', price: '£39.99', image: 'images/items/hoodies/hoodie (2).jpg' }, { type: 'Hoodie', color: 'Green', material: 'cotton authentic', price: '£39.99', image: 'images/items/hoodies/hoodie (3).jpg' }, { type: 'Hoodie', color: 'Dark Gary', material: 'cotton authentic', price: '£39.99', image: 'images/items/hoodies/hoodie (4).jpg' }, { type: 'Hoodie', color: 'Light Gary', material: 'cotton authentic', price: '£39.99', image: 'images/items/hoodies/hoodie (4).jpg' }, ] // Evaluate each hoodie and display its details hoodieArray.forEach(function (hoodie) { let card = ` <div class="card"> <img src="${hoodie.image}" style="width:100%"> <h1>${hoodie.material}</h1> <p>Color: ${hoodie.color}</p> <p class="price">${hoodie.price}</p> <p><button>Add to Cart</button></p> </div> `; // Add the card to the page document.getElementById('hoodiesContainer').innerHTML += card; });

 #hoodiesContainer { display: flex; flex-wrap: wrap; justify-content: space-between; margin: 30px; }.card { border: 1px solid gray; margin: 4px; }

 <div id="hoodiesContainer"> </div>

Answer 2

我在我的網站上做了類似的事情。 在我的帳戶顯示中（基本上只是用戶信息，實際上不是“帳戶”帳戶），用戶數據位於單個 JS object 中。

中鍵單擊/鼠標滾輪單擊/三指單擊鏈接https://majorflux.codehs.me/accounts.html並按CTRL + U並隨意復制我的代碼片段。 你不必給予信任，但如果你願意，你可以。

@Stephen_P 說的是讓我放置代碼本身而不是鏈接，所以這里是：

    <script>
        var d = {
            e: function(id){
                return(document.getElementById(id));
            },
            v: function(id){
                return(document.getElementById(id).value);
            },
            err: "data:image/svg+xml,%3Csvg%20id%3D'svgO'%20xmlns%3D'http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg'%20width%3D'100px'%20height%3D'100px'%20viewbox%3D'0%200%20100%20100'%3E%0A%3Cpath%20d%3D%22M0%2C10%20L10%2C0%20L50%2C40%20L90%2C0%20L100%2C10%20L60%2C50%20L100%2C90%20L90%2C100%20L50%2C60%20L10%2C100%20L0%2C90%20L40%2C50%20Z%20M10%2C10%20L90%2C90%20M10%2C90%20L90%2C10%20M10%2C0%20L10%2C10%20L0%2C10%20M100%2C10%20L90%2C10%20L90%2C0%20M90%2C100%20L90%2C90%20L100%2C90%20M0%2C90%20L10%2C90%20L10%2C100%20M50%2C40%20L50%2C60%20M40%2C50%20L60%2C50%22%20fill-rule%3D%22nonzero%22%20fill%3D%22%23ff0000%22%20stroke%3D%22%23ffaa00%22%2F%3E%0A%3C%2Fsvg%3E"
