Html function call on keyup - get keycode from input

Hi all,

I have an input box that is created dynamically.

Before it was created dynamically, it was always in the dom and the following code did what i wanted.

	$('#serialNumber').keyup(function(e){
		if(e.keyCode === 13){
			barCode = $(this).val()
			console.log(barCode);
			$.ajax({
				type: 'post',
				data: {'ajax' : 'one', 'barCode': barCode	},
				success: function(resp){
					$('#barCodeOutput').prepend(resp);	
				}
			})
		}
	})

now that it is not part of the dom when the page loads, i am calling it with a key up on the html element.

I dont know why i am struggling with this so much but i am really struggling to call the function and pass the keycode into it.

I have the following which does give me the keycode but having the second function in the first as it is obviously doesnt do what i want.

	function barCodeVal(){
		$(document).keyup(function(e){
			console.log(e.keyCode);
		})
	}

I would really appreciate a helping hand on this one - google just shows me react explanations.

I thought i would be back.

I now have the following:

	function barCodeVal(event){
		var e = event.keyCode;
		console.log(e)
		if(e.keyCode === 13){
			barCode = e.val()
			console.log(barCode);
			$.ajax({
				type: 'post',
				data: {'ajax' : 'one', 'barCode': barCode	},
				success: function(resp){
					$('#barCodeOutput').prepend(resp);	
				}
			})
		}
	}

The first console log works and shows 13 as the output.

The second console log does not fire suggesting that the if statement is not picking this up.

Any helpers appreciated.
