validation-regex multiline

LeeCharlebois

I have a textarea:

[html]
Description/Description :

[/html]

The regex is validating the length of the string contained in the textarea. For a few reasons, the maxlength="400" option wasn't a fit here.

What I'm trying to do now is make the regex a multiline test (because with the above regex if the user puts in a line break the regex test is false). So validation-regex="/^.{0,400}$/m" is what I want to use. But when I use that, any text at all in the textarea returns a false validation.

Anyone know what I might be doing wrong or what I need to do different?

Thanks.

You'd probably be better off handling the validation in FormAPI / Javascript - however, if you want the regex to work - I think you'd need something like:

validation-regex="^[.\n]{0,400}$"

Depending on what actually processes the directive you might be able to augment it with something like:

validation-regex="(?sm)^[.\n]{0,400}$"

But again, I think it might be cleaner to handle it with FormAPI code:

var val = IWDatacapture.getItem('field-address').getValue();
if (val.length() > 400) {
    // mark field as invalid, etc.
}
else {
  // mark field as valid, etc.
}
