javascript thread: barcode scan jumping to action page before want.

Very often barcode devices are set to "enter" after the barcode is read.
You can check this by scanning a barcode into notepad and seeing if it
gives you a carriage return.

Subject: [javascript] barcode scan jumping to action page before want.

I use ColdFusion on Windows 2000.  When I scan a barcode the form page 
jumps to the action page, before I have a chance to scan in a second 
barcode.  

This is what I placed in my header on the form page:

<script LANGUAGE="JavaScript">
<!--
function checkit(theField)
{
         if (theField.length==10)
         {
                 alert("Length is 10");
         }
}
//-->
</script>


This is in the body:
<cfloop index="X" From=1 To=#form.NumOfPlate#>
		 <tr>
		     <td><cfoutput><input type="text" 
name="Plate#X#Barcode" Size="25" maxlength="50" onKeyPress="checkit
(this)"></cfoutput></td>
		
		 </tr>
</cfloop>

thanks, 

Anna
