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 configured selectors will be used to find hungry elements in the current page. For each matching element a target will be derived from that specific element. E.g. when you configure up.radio.config.hungrySelectors.push('input'), a given input will be targeted with its derived selector (like input[name=email]).

For this to work hungry elements must have a derivable target selector.

The default polling interval in milliseconds.

Adjusts the given polling interval before it is used.

On a good network connection this returns the given interval unchanged. On a poor connection it returns the doubled interval, causing Unpoly to poll at half as frequently.

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.

When set to true, Unpoly will always allow polling.

When set to false, Unpoly will never allow polling.

To enable polling on a case-by-case basis, you may also pass a function that accepts the polling fragment and returns true, false or 'auto'. As an alternative you may also skip a polling update by preventing the up:fragment:poll event.

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