Title: Combogrid (combo) doesn't recognize barcode scanner input
Post by: phreeman on June 18, 2015, 03:07:54 PM

I have a form with an editable datagrid (edatagrid) that uses a combogrid as an editor. I can type from my keyboard into the combogrid but when I enter data through a barcode scanner, there is no response.

I can successfully read the barcode input through a datagrid editor of type text on the same row but not for the combogrid. I also tried a combogrid outside the editable datagrid with no luck. Regular, non-easyui, fields in the form also work properly. I'm thinking the combo is looking for a keypress event that it may not be receiving from the barcode scanner. What I'm trying to do is automatically fill the datagrid row resulting from a scan of a product barcode.

Any ideas?

When enter something on the combogrid's textbox and then press ENTER key, the combogrid will check the entered value to see if it is exists in the drop-down list. If the entered value does not match the list items, it will be cleared.

The barcode scanner may add a ENTER key to the end of inputed value, to solve this issue, please try to override the 'enter' key handler for your combogrid component.

Code:

$('#cc').combogrid({
	keyHandler: $.extend({}, $.fn.combogrid.defaults.keyHandler, {
		enter: function(e){
			//...
		}
	})
})

You are exactly correct. I bought a cheap barcode scanner and the default was to send the CR character at the end of the barcode. Once I disabled the termination character, everything worked as expected. Funny as I had a Symbol barcode scanner and they don not send the CR character, everything work as expected out of the box.

Thanks for your help.
