Question

我正在使用此链接第一个示例中的WinJS.UI.AutoSuggestBox：http://try.buildwinjs.com/#searchbox:simplelist1

我复制完全相同的代码，以确保我没有犯任何错误，但它仍然没有正确呈现。我不知道问题可能是什么。

PS：Data.animeList是default.js上定义的命名空间，它工作正常，我一直在其他页面上使用它。它是一个字符串数组，就像上面提到的例子中的字符串一样。使用示例中提供的数组导致了同样的事情。

以下是显示问题所在的图片（好吧，它没有渲染，因此您无法看到任何内容）：http://i.imgur.com/e0VYWB5.png

以下是代码：

        // populates the page elements with the app's data.
        ready: function (element, options) {
            // TODO: Initialize the page here.
            WinJS.UI.processAll().then(function () {

                // Renders the anime list view.

            // TODO: Respond to changes in layout.
        },
    });

    var suggestionList = Data.animeList;

    function suggestionsRequestedHandler(eventObject) {
        var queryText = eventObject.detail.queryText,
        query = queryText.toLowerCase(),

        if (queryText.length > 0) {
            for (var i = 0, len = suggestionList.length; i < len; i++) {
                if (suggestionList[i].substr(0, query.length).toLowerCase() === query) {
                    suggestionCollection.appendQuerySuggestion(suggestionList[i]);
                }
            }
        }
    };

    function querySubmittedHandler(eventObject) {

        WinJS.log && WinJS.log(queryText, "sample", "status");

我发现了问题。我的WinJS已经过时了 - 我使用的是WinJS 3，这个功能适用于WinJS 4。
