MediaTrackSupportedConstraints: height property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2017.
The MediaTrackSupportedConstraints dictionary's
height 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 height 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 height 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;
}
js
const result = document.getElementById("result");
const supported = navigator.mediaDevices.getSupportedConstraints().height;
result.textContent = supported ? "Supported!" : "Not supported!";
