up.radio up.radio.config

JavaScript property

An array of CSS selectors that is replaced whenever a matching element is found in a response. These elements are replaced even when they were not targeted directly.

By default this contains the [up-hungry] attribute.

The default [polling](/up-poll] interval in milliseconds.

Whether Unpoly will follow instructions to poll fragments, like the [up-poll] attribute.

When set to 'auto' Unpoly will skip polling updates while one of the following applies:

• The browser tab is in the foreground
• The fragment's layer is the frontmost layer.
• We should not avoid optional requests

When set to true, Unpoly will always allow polling.

When set to false, Unpoly will never allow polling.

You may also pass a function that accepts the polling fragment and returns true, false or 'auto'.

When an update is skipped due to polling being disabled, Unpoly will try to poll again after the configured interval.
