Twitter Typeahead.js庫是否限制為6個數據集？

Question

我正在使用Twitter的Typeahed.js庫從單個輸入框中搜索數據庫中的多個數據集。

我目前正在使用6個數據集（請參閱下面的代碼），我想再添加1個。 我發現它不適用於第7個數據集（來自下面代碼的products dataset ）。 在輸入框中鍵入搜索查詢時，它只會發送前六個數據集的GET AJAX請求，而忽略第七個數據集？

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%

庫文檔正在傾倒，我還沒有看到它提到你可以使用的數據集數量的任何限制...

Answer 1

好吧我明白了。 它不受限制，但默認的最大並行請求是6.來自typeahead.js文檔：

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

所以我增加了它，它的工作原理。 這是最終更正的代碼：

$('#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>',
        engine: Hogan,
        limit: 6
    },
    {
        name: 'services',
        remote: {

Answer 2

我沒有聽說過這樣的限制，我想知道前6個可能滿足的最大返回結果數量是多少？

快速測試將基本上強制幾個遠程查詢始終不返回任何內容。

如果您的第七次搜索開始受到打擊，那么可以解釋它。

Answer 3

如果有人遇到這個老問題，並希望將maxPendingRequests設置增加到6以上（或使其更小），請參閱我最近提交給維護的typeahead分支的PR 。

Answer 4

打開Twitter typeahead.js文件。

搜索：“maxPendingRequests = 6”

而不是6只要把你想要的任何價值。

現在我可以看到超過6個請求並行運行。

這對我來說可以。

不要去'maxParallelRequests'屬性它根本不起作用......

我相信它是最終解決方案.....
