Scriptrunner behavior regex

Hi folks

I Am trying to validate a single-line text box to include $ values like $1020.00 and this is the behavior on the custom field. I see no error and still can't have this behavior working

 

def field = getFieldById(getFieldChanged())
def val = field.getValue() as String

if (!val.matches("\$[0-9].[0-9]{2})")) {
field.setError("Amount must be in dollar format.")
} else {
field.clearError()
}

Your regex is both incomplete and with bad syntax

\$[0-9].[0-9]{2})
^ ^
| |
This means any |
character |
|
Where tis the corresponding open parens?

Also, it's best to use slashy strings for regular expressions in groovy to avoid the need for certain double escaping

Try like this:

if (!val.matches(/\$[0-9]*\.[0-9]{2}/)) {
...
}

I added * to mean any number of digits between "$" and "."

I also added \ in front of "." to mean a literal dot and not the regular expression that means "anything"

And I removed the extra parens

Thank you for sharing your knowledge and insights. Overlooked () and regex is always tricky for me. Anyways Thanks again.

I recommend  https://regex101.com/ to test and validate your regex.

Then double-test in the scriptrunner console with something like this with different "val" input until you are satisfied the logic works.

def val = '100.00'
if (!val.matches(/\$[0-9]*\.[0-9]{2}/)) {
"Amount must be in dollar format."
} else {
"good"
}
