如何在Windows 8模板中為項目添加新類？

Question

我正在嘗試使用模板設計這樣的東西

但是我不能在data.js中包含以下代碼：

var sampleItems = [
    { group: sampleGroups[0], importancia: "alta", title: "Item Title: 1", subtitle: "Item Subtitle: 1", description: itemDescription, content: itemContent, backgroundImage: lightGray },
    { group: sampleGroups[0], title: "Item Title: 2", subtitle: "Item Subtitle: 2", description: itemDescription, content: itemContent, backgroundImage: darkGray },
    { group: sampleGroups[0], title: "Item Title: 3", subtitle: "Item Subtitle: 3", description: itemDescription, content: itemContent, backgroundImage: mediumGray },
    { group: sampleGroups[0], title: "Item Title: 4", subtitle: "Item Subtitle: 4", description: itemDescription, content: itemContent, backgroundImage: darkGray },
    { group: sampleGroups[0], title: "Item Title: 5", subtitle: "Item Subtitle: 5", description: itemDescription, content: itemContent, backgroundImage: mediumGray }
];

當我嘗試將新選項添加​​到groupedItem.html的此部分時：

<div class="itemtemplate" data-win-control="WinJS.Binding.Template">
    <div class="item" data-win-bind="className: importancia">
        <img class="item-image" src="#" data-win-bind="src: backgroundImage; alt: title" />
        <div class="item-overlay">
            <h4 class="item-title" data-win-bind="textContent: title" style="margin-left: 0px; margin-right: 291.08px;"></h4>
            <h6 class="item-subtitle win-type-ellipsis" data-win-bind="textContent: subtitle"></h6>
        </div>
    </div>
</div>

結果是這樣的：

我該如何解決？ 我沒有在CSS中添加任何內容

首先，您需要在data.js文件中為所需組指定數據項的數量。 然后作為此MSDN教程編輯groupitem js和css文件。 您會找到您想要的
