什麼是滾動條負載的client.javascript.plugins？

Question

我正在查看實際的Rollber來自瀏覽器的有效載荷數據。 我之前查過了官方文檔。但是，它有一些未知的數據，如下所示。

• API Reference - Items (POST)

有效載荷數據（client財產摘錄如下）：

    }, 
    "runtime_ms": 225 
}, 

... 

我要明確的client.javascript.plugins數據哪裏是他們來了，翻車防護杆怎麼弄這些數據。

數據來自插件陣列是導航對象的屬性在大多數瀏覽器中，參見https://developer.mozilla.org/en-US/docs/Web/API/NavigatorPlugins/plugins
