Two bar code scanners

Dziugas_S_ — Mon, 04 Jan 2016 04:28:08 GMT

Hello. I'm trying to implement two barcode scanners to two buttons. The problem is that when I click one button or the other, both scripts for the scanners are activated. How to fix that one button uses one script and the other uses the other script?

Button1:

<a class="uib-graphic-button default-graphic-sizing default-image-sizing hover-graphic-button active-graphic-button default-graphic-button default-graphic-text widget uib_w_52 d-margins skenavimo_tekstas media-button-text-bottom" data-uib="media/graphic_button"
                    data-ver="0" id="scan1" style="position: relative; display:block; float:center; width: 10%; padding-bottom: 10%;
    width: 50%; margin: 0 auto; " onclick="scanNow();">
                        <img src="images/barcode.png">

                        <span class="uib-caption">Check</span>
                    </a>

Button2:

<a class="button widget uib_w_54 d-margins testas icon camera yellow" data-uib="app_framework/button" data-ver="1" id="scan2" onclick="scanNow2();">Scan</a>

Here is the first script:

<script>
        function scanNow()
            {
                //this function launches the QR Code scanner.
                intel.xdk.device.scanBarcode();
            }
            document.addEventListener("intel.xdk.device.barcode.scan",function(evt){
                if (evt.success == true) {
                    //successful scan
                   alert("I'm number 1");
                }
                else 
                {
                    //failed scan
                    alert("ERROR");
                }
            },false);
    </script>

And here is the second script:

<script>
function scanNow2()
                {
                    //this function launches the QR Code scanner.
                    intel.xdk.device.scanBarcode();
                }
                document.addEventListener("intel.xdk.device.barcode.scan",function(ted){
                    if (ted.success == true) {
                        //successful scan
                    alert("I'm number 2");
                    }else{
                        alert("ERROR");
                    }
                 },false);
        </script>

That is cause u have 2 event

That is cause u have 2 event handlers already fired and the code is rightly executing both event handlers.

You can do something like this:

<script>

var scan = 0; 
        
function scanNow(){
    scan = 1;
    intel.xdk.device.scanBarcode();
}
        
function scanNow2(){
    scan = 2;
    intel.xdk.device.scanBarcode();
}

document.addEventListener("intel.xdk.device.barcode.scan",function(ted){
    if (ted.success == true) {
        if(scan == 1){
            scan = 0;
            alert("I'm number 1");
        } else if(scan == 2){
            scan = 0;
            alert("I'm number 2");
        }
    }else{
        alert("ERROR");
    }
},false); 

</script>
