我正在使用Twitter 中的Typeahed.js库从单个输入框中搜索我的数据库中的多个数据集。

我目前正在使用 6 个数据集（参见下面的代码），我想再添加 1 个。我发现它不适用于第 7 个数据集（products dataset来自下面的代码）。在输入框中输入搜索查询时，它只会发送前六个数据集的 GET AJAX 请求，而忽略第 7 个？

GET http://127.0.0.1/app/typeahead_orders.json?q=MSI-20mA
GET http://127.0.0.1/app/typeahead_invoices.json?q=MSI-20mA
GET http://127.0.0.1/app/typeahead_services.json?q=MSI-20mA%
GET http://127.0.0.1/app/typeahead_serials.json?q=MSI-20mA%
GET http://127.0.0.1/app/typeahead_users.json?q=MSI-20mA%
GET http://127.0.0.1/app/typeahead_licenses.json?q=MSI-20mA%

图书馆文档是倾倒的，我没有看到它提到你可以使用的数据集数量的任何限制......

好的，我想通了。不受限制，但默认最大并行请求为 6。来自 typeahead.js 文档：

maxParallelRequests – The max number of parallel requests typeahead.js can have pending. Defaults to 6.

所以我增加了这个并且它有效。这是最终更正的代码：

$('#search-query').typeahead([
    {
        name: 'orders',
        remote: {
            url: base_url+"utilities/ajaxprocess/typeahead_orders.json?q=%QUERY",
            maxParallelRequests: 8,
        },
        template: '<a href="'+base_url+'orders/view/{{order_id}}">{{value}} - Reference no.: {{reference_number}}</a>',
        header: '<h5 class="search-result-header"><i class="icon-shopping-cart"></i> Orders</h5>',
        engine: Hogan,
        limit: 6
    },
    {
        name: 'invoices',
        remote: {
            url: base_url+"utilities/ajaxprocess/typeahead_invoices.json?q=%QUERY",
            maxParallelRequests: 8,
        },

我没有听说过这样的限制，我想知道前6个可能满足的返回结果的最大数量是多少？

一个快速测试将基本上强制您的几个远程查询始终不返回任何内容。

如果您的第七次搜索开始受到打击，那可以解释它。

打开 Twitter typeahead.js 文件。

搜索：“maxPendingRequests = 6”

而不是 6 只需输入您想要的任何值。

现在我可以看到超过 6 个请求并行运行。

这对我来说可以。

不要去寻找'maxParallelRequests'属性，它根本不起作用......

我相信这是最终的解决方案......

如果有人遇到这个老问题，并且想将 maxPendingRequests 设置增加到 6 以上（或使其更小），请参阅我最近提交给 typeahead 的维护分支的这个 PR 。
