Summary

- -

WebFM API предоставляет доступ к модулю FM радио устройства. Этот интерфейс поможет Вам включить или выключить FM радио и настроить его на нужную станцию. Это достижимо с помощью параметра {{domxref("window.navigator.mozFMRadio","navigator.mozFMRadio")}}.

Event handlers

- -
-
{{domxref("FMRadio.onenabled")}}
-
A handler for the {{event("enabled")}} event; It is triggered when the radio has been turned on
-
{{domxref("FMRadio.ondisabled")}}
-
A handler for the {{event("disabled")}} event; It is triggered when the radio has been turned off
-
{{domxref("FMRadio.onantennaavailablechange")}}
-
A handler for the {{event("antennaavailablechange")}} event; It is triggered when an antenna is plugged or unplugged
-
{{domxref("FMRadio.onfrequencychange")}}
-
A handler for the {{event("frequencychange")}} event; It is triggered whenever the radio frequency is changed
-
- -

Методы

- -
-
{{domxref("FMRadio.enable()")}}
-
Turns on the radio on the given frequency. This function throws if called with no argument. Returns a {{domxref("DOMRequest")}} for the success or error of the operation.
-
{{domxref("FMRadio.disable()")}}
-
Turns the radio off. Returns a {{domxref("DOMRequest")}} which success indicates that the radio has properly been disabled
-
{{domxref("FMRadio.setFrequency()")}}
-
Asynchronously changes the radio frequency. The value has to be between frequencyLowerBound and frequencyUpperBound. Trying to set outside the bounds results in an error.
-
Returns a {{domxref("DOMRequest")}} which success indicates the frequency has properly been changed.
-
{{domxref("FMRadio.seekUp()")}}
-
Asks the radio to find a new frequency (usually greater than the current one). If one is successfully found, a frequencychange event is fired. Returns a {{domxref("DOMRequest")}} which success indicates that the search has started. The search circles back to lower frequencies when the highest frequency has been reached.
-
{{domxref("FMRadio.seekDown()")}}
-
Same as above, but searching in frequencies lower than the current one. The search cirlces back to higher frequencies when the lowest frequency has been reached.
-
{{domxref("FMRadio.cancelSeek()")}}
-
Cancels the radio seek if one was happening. Returns a {{domxref("DOMRequest")}} which success indicates that the frequency search has been cancelled.
