Describes sample barcode scanner projects.
The following sample configures the namespace, and calls the scan method to
launch the scanner, and upon detection of a barcode, pass control back to your application,
along with the barcode data. For Android only, the encode method encodes a
supported type of information (in this sample, text) as a barcode. For a complete Barcode
Scanner sample, see Getting Started with Kapsel
.
document.addEventListener("deviceready", init, false);
function scan() {
log("scanning");
cordova.plugins.barcodeScanner.scan(scanSuccessCallback, scanErrorCallback);
}
function scanSuccessCallback(result) {
log(JSON.stringify(result));
/*
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
*/
}
function scanErrorCallback(error) {
alert("Scanning failed: " + JSON.stringify(error));
}
function encode() {
log("encoding");
if (device.platform == "Android") { //Not supported on iOS
var stringToEncode = "http://www.sap.com";
cordova.plugins.barcodeScanner.encode(cordova.plugins.barcodeScanner.Encode.TEXT_TYPE, stringToEncode, encodeSuccessCallback, encodeErrorCallback);
}
else {
log("Encoding is not supported on iOS. See https://github.com/wildabeast/BarcodeScanner/issues/106");
}
}
function encodeSuccessCallback(result) {
log(JSON.stringify(result));
}
function encodeErrorCallback(error) {
alert("Encoding failed: " + JSON.stringify(error));
}
function log(line) {
var results = document.getElementById("scan_results");
results.innerHTML+= "<br>" + line;
}
