how to scan barcode using phonegap

I need to scan a 开发者_开发技巧barcode using phonegap in Android and iPhone. Is there a way to do this?

Kris Erickson is correct, the Zxing & Phonegap projects has already taken care of the heavy lifting for you. (My current SO reputation disallows me from commenting, but I would have.)

I've just made an Phonegap/Android app that scans a QR barcode using the plugin here. Follow the instructions and you should be successful. It's possible that the plugin has been written since Kris's answer.

The Javascript is simple, taken straight from https://github.com/phonegap/phonegap-plugins/

    var scanBarcode = function() {
    window.plugins.barcodeScanner.scan( BarcodeScanner.Type.QR_CODE,function(result) {
        alert("We got a barcode: " + result);
    }, function(error) {
        alert("Scanning failed: " + error);
    }, {yesString: "Install"}
    );
 }

Your going to have a build a Phonegap plug-in, but the hard work has already be done for you by zxing.

I recently used the ZBar plugin + the PhoneGap plugin to access ZBar. More details here - http://blog.infoentropy.com/Use_ZBar_barcode_reader_with_PhoneGap.
