ValidationTextBox : bug in regExp parsing

[Josh Trutwin]

I wanted to create a reg exp that validated a number had up to at most 2 decimal places, or none. (e.g. 50, 50.1, 50.98 but not 50.982)

I tested the following regular expression here ​http://www.regular-expressions.info/javascriptexample.html :

$((\d+\.\d{1,2})|(\d+))

This does what I want it to do, but when I feed this into a validation textbox using:

regExp="[(\d+\.\d{1,2})|(\d+)]"

It doesn't work as expected, also tried replacing square brackets with parans, no change. Digging into this, it seems that the regular expression test that is being run is on the following regexp in the ValidationTextBox? validate() routine:

^{((?:(?:((?:(?:(?:(?:0|[1-9]\d{0,2}(?:[,]\d{3})*)|(?:0|[1-9]\d*))(?:\.\d{0,3}|))|(?:(?:\.\d{0,3}|)))))|(?:-((?:(?:(?:(?:0|[1-9]\d{0,2}(?:[,]\d{3})*)|(?:0|[1-9]\d*))(?:\.\d{0,3}|))|(?:(?:\.\d{0,3}|)))))))?$}

I don't pretend to understand what this is doing, but it doesn't work. It'll accept a number with 3 decimals but not 4. Why did my regexp get turned into this beast?

I'm not sure if it matters but I also have a constraint of min:0 on the textbox.

Thanks,

Josh

I meant to say "validator" method above.

Also - I tried adding in the anchors using:

regExp="$((\d+\.\d{1,2})|(\d+))^"

No change as these appear to be stripped and hard coded into the validator method.

Doug, sounds like the partial matching stuff?

Josh - btw you can adjust trac settings to automatically email you w/out putting your name in the CC field.

The partial match output you listed indicates that the widget type must not have been dijit.form.ValidationTextBox?, but a subclass like NumberTextBox? which has a hardcoded regExp. Also, the regExp attribute should have been specified as "(\d+\.\d{1,2})|(\d+)". I changed the regExp in the q22 example in dijit/form/test_validate.html and it worked perfectly.

You are right - it was a NumberTextBox?, my bad, should've included that minute detail. :P

There is still problem though - if I change this to a ValidationTextBox?, I lose the ability to set a min constraint.

Is there a regExp I can pass to ValidationTextBox? that says the results must be numeric, with at most 2 decimal places and also greater than or less than some max/min?

RangeBoundTextBox? with your regExp attribute should do it

Thank you - works great!
