------------------------ AND ------------------------ -----Original Message----- From: Tony Schreiber [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 22, 2001 11:31 AM To: CF-Talk Subject: Re: Bar Code Scan I've been doing nothing but barcode apps for the last few weeks (warehouse management and shipping system, all in CF) and here's an extremely helpful tip: Keyboard wedge scanners have the ability to be programmed and most will come by default with a setting of adding a CR to each barcode scan. In IE, pressing return will submit a form, so this works great. But what happens when you want to scan more than one barcode? Javascript to the rescue: <SCRIPT LANGUAGE="JavaScript"> <!-- function checkForm(form) { valid = false; if (form.orderno.value.length > 0 && form.tracking.value.length > 0) { valid = true; } else { form.tracking.focus(); } return valid; } //--> </SCRIPT> This is from a page that waits for a order scan and a delivery confirmation label scan. This is in the form tag: onSubmit="return checkForm(this);" So, the javscript prevents the form from submitting until both fields are filled AND moves the focus from the first field to the second after the frist scan! Tada! Hope that helps. That's been my little up my sleeve trick lately. -----Original Message----- From: Rich Tretola [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 04, 2001 5:16 PM To: CF-Talk Subject: Cue Cat I picked up one of those cue cats from radio shack today, has anyone ever written a tag that will use this as a barcode scanner?
