非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

non-standard , Firefox-specific RTCIceCandidatePairStats property selected indicates whether or not the candidate pair described by the object is the one currently being used to communicate with the remote peer.

句法

isSelected = icpStats.selected;

值

A Firefox-specific Boolean value which is true if the candidate pair described by this object is the one currently in use.

In any other browser, you can determine the selected candidate pair by looking for a stats object of type transport , which is an RTCTransportStats object. That object's selectedCandidatePairId property indicates whether or not the specified transport is the one being used.

范例

The function shown in this example identifies the currently-selected candidate pair from a statistics report by first iterating over each report, looking for a transport report; when one is found, that transport's selectedCandidatePairId is used to get the RTCIceCandidatePair describing the connection.

If that fails, then the second section iterates over the reports, looking for a candidate-pair record whose Firefox-specific selected 特性为 true . This candidate pair is then returned as the currently-selected one.

function getCurrentCandidatePair(statsResults) {
  statsResults.forEach(report => {
    if (report.type === "transport") {
      currentPair = statsResults.get(report.selectedCandidatePairId);
    }
  });
  if (!currentPair) {
    statsResults.forEach(report => {
      if (report.type === "candidate-pair" && report.selected) {
        currentPair = report;
      }
    });
  }
  return currentPair;
}
