The interface XRInputSourceArray
represents a live list of WebXR input sources, and is used as the return value of the XRSession
property inputSources
. Each entry is an XRInputSource
representing one input device connected to the WebXR system.
In addition to being able to access the input sources in the list using standard array notation (that is, with index numbers insize square brackets), methods are available to allow the use of iterators and the forEach()
method is also available.

you can use to walk the list of key/value pairs in the list. Each item returned is an array whose first value is the index and whose second value is theXRInputSource
at that index. forEach()
- Iterates over each item in the list, in order from first to last.
keys()

, passing into it the first item in the input source list, if the list isn't empty.
let sources = xrSession.inputSources; if (sources.length > 0) { handleInput(sources[0]); }
