Javascript 调用OnSuggestionRequested（win8）时出现0x800000E错误

我想在我的windows 8应用程序中编写搜索合同。基本上，除了建议列表之外，所有的事情都按它应该的那样工作。 总是在我进入函数时，如果我应该在其中添加建议，我会得到运行时错误0x800000E

我只是复制粘贴了示例中的代码，唯一的区别是从数据库加载数据

appModel.Search.SearchPane.getForCurrentView().onsuggestionsrequested = function (eventObject) {
    var queryText = eventObject.queryText, suggestionRequest = eventObject.request;
    var query = queryText.toLowerCase();
    var maxNumberOfSuggestions = 5;
    mkData.getWords(eventObject.queryText, maxNumberOfSuggestions, function (suggestionList) {
        for (var i = 0, len = suggestionList.length; i < len; i++) {
            if (suggestionList[i].substr(0, query.length).toLowerCase() === query) {
                suggestionRequest.searchSuggestionCollection.appendQuerySuggestion(suggestionList[i]);
                if (suggestionRequest.searchSuggestionCollection.size === maxNumberOfSuggestions) {
                    break;
                }
            }
        }
    });
    if (suggestionRequest.searchSuggestionCollection.size > 0) {
        WinJS.log && WinJS.log("Suggestions provided for query: " + queryText, "sample", "status");
    } else {
        WinJS.log && WinJS.log("No suggestions provided for query: " + queryText, "sample", "status");
    }
};

appModel.Search.SearchPane.getForCurrentView（）.onsuggestionsrequested=函数（eventObject）{
var queryText=eventObject.queryText，suggestionRequest=eventObject.request；
var query=queryText.toLowerCase（）；
var maxNumberOfSuggestions=5；
mkData.getWords（eventObject.queryText，maxNumberOfSuggestions，函数（suggestionList）{
for（var i=0，len=suggestionList.length；i0）{
WinJS.log&&WinJS.log（“为查询提供的建议：”+queryText，“示例”，“状态”）；
}否则{
WinJS.log&&WinJS.log（“未提供查询建议：”+queryText、“示例”、“状态”）；
}
};

如果我用一个静态的建议数组交换Ajax调用，它会起作用：( 建议列表中有好的词语

我已经找到了解决方案，但只在C#中找到了。开发人员必须添加wait关键字，但在javascript中我没有这个

提前感谢！

我现在自己解决了。这里是解决方案。您必须使用延迟。几乎没有记录：(

appModel.Search.SearchPane.getForCurrentView().onsuggestionsrequested = function (eventObject) {
    var queryText = eventObject.queryText, suggestionRequest = eventObject.request;
    var maxNumberOfSuggestions = 5;
    var deferral = eventObject.request.getDeferral();
    mkData.getWords(queryText, maxNumberOfSuggestions, function (suggestionList) {
        suggestionRequest.searchSuggestionCollection.appendQuerySuggestions(suggestionList);
        deferral.complete();
    });
    if (suggestionRequest.searchSuggestionCollection.size > 0) {
        WinJS.log && WinJS.log("Suggestions provided for query: " + queryText, "sample", "status");
    } else {
        WinJS.log && WinJS.log("No suggestions provided for query: " + queryText, "sample", "status");
    }
};
