Answer 1

你讓自己變得復雜

條形碼掃描儀插件是

https://github.com/phonegap/phonegap-plugin-barcodescanner

上面提到的條形碼掃描儀已經可以訪問相機，您不必使用另一個插件，例如您提到的cordova相機預覽插件

例子：

//plugin options
var options= {
      preferFrontCamera : true, // iOS and Android
      showFlipCameraButton : true, // iOS and Android
      showTorchButton : true, // iOS and Android
      torchOn: true, // Android, launch with the torch switched on (if available)
      saveHistory: true, // Android, save scan history (default false)
      prompt : "Place a barcode inside the scan area", // Android
      resultDisplayDuration: 500, // Android, display scanned text for X ms. 0 suppresses it entirely, default 1500
      formats : "QR_CODE,PDF_417", // default: all but PDF_417 and RSS_EXPANDED
      orientation : "landscape", // Android only (portrait|landscape), default unset so it rotates with the device
      disableAnimations : true, // iOS
      disableSuccessBeep: false // iOS and Android
  }

 //success callback
function onSuccess(result) {
      alert("We got a barcode\n" +
            "Result: " + result.text + "\n" +
            "Format: " + result.format + "\n" +
            "Cancelled: " + result.cancelled);
 }

//error callback
function onError(error) {
      alert("Scanning failed: " + error);
}

cordova.plugins.barcodeScanner.scan(onSuccess, onError, options);
