Mobile device camera driven barcode scanner:

How to implement zxing barcode scanning app

The zxing application can be called by use of a response request (eg. hyperlink) in the following manner:

<a href ="zxing://scan/?ret={returnpage}?bd={CODE}&SCAN_FORMATS={UPC_A,EAN_13,Code39}"> text or image </a>

URI scheme: zxing://
Specify task: Scan/
Return page: ret={returnpage}
Querystring parameter: bd={{CODE}} to catch the retrieved data from the zxing barcode scanning app
Querystring parameter: SCAN_FORMATS={UPC_A,EAN_13,Code39} to specify the barcode formats.

Example to retrieve the scanned barcode on the {returnpage}:

Code

Create Script in the <head> :

Now call the javascript function from eg. the body onload:

Check if your app is installed

To check if your app is installed you can do like the following example:

Code <script type="text/javascript">
  var appurl = 'unitech://scan/?ret={returnpage}';
  var applocation = '{link to the app/eg. scanutil.apk}';
  var timeout;
  function preventPopUp();
    clearTimeout(timeout);
    timeout = null;
    window.removeEventListener('pagehide', preventPopup);;
  }
  function checkApp() {
    timeout = setTimeout(function) {
      document.location = appurl;
      if (confirm('You do not have the app installed, do you want to install it now?')) {
        document.location = applocation;
      }
    }
    window.addEventListener('pagehide', preventPopup);
  }, 5);
</script>

URI scheme: unitech://
Specify task: Scan/
Return page: ret={returnpage}
Querystring parameter: bd={{CODE}} to catch the retrieved data from the Unitech barcode scanner app

Example to retrieve the scanned barcode on the {returnpage}:

Code

Create Script in the <head> :

First function is to get the parameters from the querystring

  function qs(key) {
     var vars = [], hash;
     var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
     for (var i = 0; i < hashes.length; i++) {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
     }
     return vars[key];
  }

Second function is to retrieve the result from the given parameter:

  function getBarcodeValue(key) {
     var result = qs(key);
     if (result != null) {
        var text = result;
        document.getElementById('BarcodeData').innerHTML = text;
     };
  }
</script>
