UI.setPollInterval介绍

[英]Sets the interval with which the UI should poll the server to see if there are any changes. Polling is disabled by default.

Note that it is possible to enable push and polling at the same time but it should not be done to avoid excessive server traffic.

Add-on developers should note that this method is only meant for the application developer. An add-on should not set the poll interval directly, rather instruct the user to set it.
[中]设置UI轮询服务器以查看是否有任何更改的间隔。默认情况下，轮询处于禁用状态。
请注意，可以同时启用推送和轮询，但不应这样做以避免过多的服务器流量。
附加组件开发人员应该注意，此方法仅适用于应用程序开发人员。附加组件不应直接设置轮询间隔，而应指示用户进行设置。
