MediaTrackSupportedConstraints: volume property

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The MediaTrackSupportedConstraints dictionary's volume property is a read-only Boolean value which is present (and set to true) in the object returned by MediaDevices.getSupportedConstraints() if and only if the user agent supports the volume constraint. If the constraint isn't supported, it's not included in the list, so this value will never be false.

You can access the supported constraints dictionary by calling navigator.mediaDevices.getSupportedConstraints().

Value

This property is present in the dictionary (and its value is always true) if the user agent supports the volume constraint. If the property isn't present, this property is missing from the supported constraints dictionary, and you'll get undefined if you try to look at its value.

Examples

<div id="result"></div>

#result {
  font:
    14px "Arial",
    sans-serif;
}

const result = document.getElementById("result");
const supported = navigator.mediaDevices.getSupportedConstraints().volume;
result.textContent = supported ? "Supported!" : "Not supported!";
