javascript - 输入捕获的特征检测=视频

Question

我需要使用一个字段以使 Android 和 iOS 用户能够选择用他们的相机拍摄照片，我在该输入字段后附加了 jQuery 但我如何进行特征检测所以我只向浏览器显示该字段需要那个方法而不是例如flash 还是 getUserMedia？

有点像，

if (navigator.captureFeature) {
 //append the input field
} else {
 //device does not support capture=camera
}

也许这有帮助？

This looks like what you want:

function hasGetUserMedia() {
  // Note: Opera is unprefixed.
  return !!(navigator.getUserMedia || navigator.webkitGetUserMedia ||
            navigator.mozGetUserMedia || navigator.msGetUserMedia);
}

if (hasGetUserMedia()) {
  // Good to go!
} else {
  alert('getUserMedia() is not supported in your browser');
}
