On Text Change - DO STUFF

[tqeonline]

Hello All,

I have two text boxes:
1. txtEmployeeID
2. txtDeviceID

The application will use a barcode scanner and depending on which item is scanned I want it to populate correctly.

Example: say that the txtDeviceID is highlight and an employee scans their badge, the first letter is an "E" so I want the textbox to be smart and detect that first letter and populate the correct box. So it would take the input from the DeviceID and populate the EmployeeID with it, then clear out the DeviceID and set the focus to the Device ID.

I figured the best way to do this is javascript... but i know nothing about Javascript

Any pointerS?

Hi

As you can never trust the client side, you must validate it with server-side code too.

Unless there are more client-side actions to be performed before submitting the [tt]form[/tt], I would choose a user-friendlier[sup](*)[/sup] way : a single [tt]input[/tt] where any[sup](**)[/sup] of those two barcode types can be entered.

[small](*) At least for me. YMMV.[/small]
[small](**) Or maybe even both, separated with space, comma, whatever.[/small]

Well the way I want it to work, where i need guidance, is this is going to be a barcode scanner scanning in an ID.

If the text scanned starts with an E and its not the employee text box I want it to populate the employee text box then set focus to the Device text box.

Ex. focus is in the Device ID textbox and I scan my badge "E1234" I want their to be logic in that box that says

if left(txtDeviceID,1) = "E" then
txtEmployeeID.text = txtDeviceID.text
txtDeviceID.text = ""
txtDeviceID.setfocus
End if

But I can't get this to function right in ASP.net and I don't know Javascript that well.

correction:

if ucase(left(txtDeviceID.text,1)) = "E" then

Hi

The exact translation of your code :

if (txtDeviceID.value[0].toUpperCase() == 'E') {
  txtEmployeeID.value = txtDeviceID.value
  txtDeviceID.value = ''
  txtDeviceID.focus()
}

Note that I have no idea how ASP would know what txtDeviceID and txtEmployeeID are.
