Twitter Typeahead.js库是否限制为6个数据集？

标签： javascript autocomplete typeahead.js

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

我目前正在使用6个数据集（请参阅下面的代码），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）。在输入框中键入搜索查询时，它只会为前六个数据集发送GET AJAX请求，而忽略第7个数据集？

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%

库文档正在倾倒，我还没有看到它提到你可以使用的数据集数量的任何限制......

好的我明白了。它没有限制，但默认的最大并行请求是6.来自typeahead.js docs：

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,
        },
        template: '<a href="'+base_url+'invoices/view/{{invoice_id}}">{{invoice_number}} - {{company}}</a>',
        header: '<h5 class="search-result-header"><i class="icon-file"></i> Invoices</h5>',

答案 1 :(得分：0)

我没有听说过这样的限制，我想知道前6个可能满足的最大返回结果数量是多少？

快速测试将基本上强制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，那么可以解释它。

答案 2 :(得分：0)

如果有人遇到这个旧问题，并希望将maxPendingRequests设置增加到6以上（或使其更小），请参阅this PR我最近提交给维护的typeahead分支。

答案 3 :(得分：0)

打开Twitter typeahead.js文件。

搜索：“maxPendingRequests = 6”

而不是6只要放置你想要的任何值。

现在我可以看到超过6个请求并行运行。

它适用于我。

不要选择“maxParallelRequests”属性，它根本不起作用......

我确信它是最终解决方案.....
