Xataface Forums

This might be an idiotic question (apologies ), but is there a simple way to prevent dataface from saving record changes when in edit mode after the ENTER key is pressed in any given field? I'm using a barcode scanner to enter some of the data: it sends the Enter keystroke after each scan which as a result saves the current dataface record.

Thanks in advance!

Ah.. yes.. sounds like a pain. You can try this solution:
http://support.microsoft.com/kb/298498

In order to implement the example given in that kb article, note that you can add javascript event handlers to any fields in the fields.ini file using:

widget:atts:%attname% = ...

so in the kb article example, you would have

widget:attsnkeydown="testForEnter();"

Let me know if this works for you.

Here's the code I'm using to disable the Enter key on _all_ fields:

*****fields.ini

widget:attsnkeypress="stopEnterKey(event.keyCode);"


*****and javascript:

function stopEnterKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 13) && (node.type=="text")) {return false;}

document.onkeypress = stopEnterKey;
}

Thanks for posting this. If you get a chance, this would make a nice little how-to article. You can post a new how-to document at:
