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 poll if 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'.
