RegEx test and change to uppercase

[deckarduk]

Hi there,

Please can some one help me.

I've been playing around with custom keystroke scripts and all has gone ok so far apart from this variation.

I have a text field that has a RegEx test to allow only character 0-9, a-z & A-Z.

Here's the code:

var r = new RegExp("^[0-9a-zA-Z]*$");

var result = r.test(event.change);

if (result == true) {console.println("Here - stage 1 true")} else {console.println("Here - stage 1 false")};

if ( result != true )

{

    event.change = "";

    console.println("Here - stage 2 false");

} else {

    event.change.toUpperCase();

    console.println("Here - stage 2 true");

}

What I'm trying to do with this one is allow the user to enter characters 0-9, a-z & A-Z.

However, if the user enters any lowercase letter I'm trying to change it toUpperCase().

So far I've not succeeded with this

Think I've solved it.

The appears to work:

var r = new RegExp("^[0-9a-zA-Z]*$");

var result = r.test(event.change);

if ( result != true )

{

    event.change = "";

} else {

    event.change = event.change.toUpperCase();

}

P.S.     Here's another question... how do I format my code correctly for this forum?

          Thanks.

To reject the entered value you should use this code:

event.rc = false;

Thanks for the help.

After a little playing around I managed to condense everything to 2 lines.

var r = new RegExp("^[0-9a-zA-Z]*$");
if (r.test(event.change)) {event.change = event.change.toUpperCase()} else {event.rc = false};

This seems to do the trick.

Great job!

Thanks!

Just another quick question that's come to mind.

I've implemented this as a 'Custom Keystroke Script'.

Should the code above have a if(!event.willCommit) at the start?

If the keystrokes are being formatted with this method is the if(!event.willCommit) necessary?

Thanks.

I don't think you need it.

Thanks for the reply and help.

The question popped up because I've seen a few examples with it in.

Thanks again.
