{{APIRef("HTML DOM")}}
The
HTMLMediaElement.networkState property indicates the
current state of the fetching of media over the network.
An unsigned short. Possible values are:
| Constant | Value | Description |
|---|---|---|
NETWORK_EMPTY | 0 | There is no data yet. Also, readyState is HAVE_NOTHING. |
NETWORK_IDLE | 1 | HTMLMediaElement is active and has selected a resource, but is not using the network. |
NETWORK_LOADING | 2 | The browser is downloading HTMLMediaElement data. |
NETWORK_NO_SOURCE | 3 | No HTMLMediaElement src found. |
This example will listen for the audio element to begin playing and then check if it is still loading data.
<audio id="example" preload="auto">
<source src="sound.ogg" type="audio/ogg" />
</audio>
const obj = document.getElementById("example");
obj.addEventListener("playing", () => {
if (obj.networkState === 2) {
// Still loading…
}
});
