I’ve developed several different Mobile App Builder Functions to scan barcodes. I’ve successfully developed a function to consume inventory from the alm_consumable table. Using a single input of type Barcode and that is working.
Example Code in WriteBackFunction:
(function WriteBackAction(parm_input, parm_variable, actionResult) {
// get input values
gs.info('Consume Inventory Function: parm_input = ' + JSON.stringify(parm_input, null, '\t'));
})(parm_input, parm_variable, actionResult);
This is the output of the function in the system logs:
Consume Inventory Function: parm_input = {
"stockroom": "32c1ffd51bf17110a95611f8bc4bcb72",
"quantity": "1",
"site_location": "dc8f4ef4db6f8c50f76bda75ca961970",
"barcode": "CPM0003194"
}
The first method that I tried:
Configuring my Consume Multiple Barcodes function I used this reference: Configure input form screens with grouped scan barcode inputs (servicenow.com)
My configuration:
Input form section:
Result
- that the barcode scanning works and will scan multiples barcodes:
- It appears to carry values back to main form:
- However, the submit doesn’t send all the input values.
Using this same code in my Consume Multiple Function:
(function WriteBackAction(parm_input, parm_variable, actionResult) {
// get input values
gs.info('Consume Multiple Function: parm_input = ' + JSON.stringify(parm_input, null, '\t'));
})(parm_input, parm_variable, actionResult);
I get this which is missing barcodes:
Consume Multiple Function: parm_input = {
"quantity": "1",
"stockroom": "3beabf471bbbf110a95611f8bc4bcb70"
}
Based on the documentation I’d expect it to look like this:
Consume Multiple Function: parm_input = {
"barcodes": {"inland_barcode": ["CPM0003647", "CPM0003647"]},
"quantity": "1",
"stockroom": "3beabf471bbbf110a95611f8bc4bcb70"
}
Then second I tried this method:
Configure a grouped input for multiple scans (servicenow.com)
But the barcode inputs did not show on the Input Form Screen. But the input shows up after I click submit. The functionality appears to work , and it has the same output to the log files.
I've been able to complete my code and have a function mobile app that does multiple barcode scanning and keeps track of the list of scanned items. I've made it work for a barcode scanner as well as for the using the Cabrillo framework. I'm using the native Cabrillo in the Now Mobile custom application that uses a Page/Widget on our Inventory portal. Here are a couple screenshots of the configuration:
As you can see, we have multiple icons that point to Mobile Web Screens component. Here is how our Consume Inventory configuration that points to the inventory portal using the barcode page with a type of consume. We use the same page to do consuming as well as reconciling inventory.
I only use the cabrillo to add the buttons as well as accessing the camera on the mobile device to do the barcode scanning. Here is some of my Client Script code from my widget:
c.isNative = cabrillo.isNative();
cabrillo.viewLayout.setBottomButtons([{
title: 'Scan Code',
enabled: true,
backgroundColor: '#2d86d5',
textColor: '#FFFFFF'
}, {
title: c.data.type + ' Items',
enabled: true,
backgroundColor: '#005EB8',
textColor: '#FFFFFF'
}], function(btnIndex) {
switch (btnIndex) {
case 0:
c.getBarcode();
break;
case 1:
c.submitItems();
break;
}
});
c.getBarcode = function() {
cabrillo.camera.getBarcode().then(function(value) {
c.data.entered_barcode = value;
c.addBarcode();
});
};This is only some of my code, but this should be enough to get you going. The addBarcode function sues the entered_barcode to add to the barcode to a list on the page. You might be able to do the same only capturing your error in the list.
Hope this helps.
