inputtext, pattern, number, float

[ebrentnelson]

I am using the pattern attribute in the inputtext tag to limit my users to only be able to enter numbers and a decimal(ie [0-9.]* ), but the problem I am running into is that the user is able to enter the following:

15.15..15

Is there a way to only allow them to enter ONE decimal?

thank you.

The following is for floating point numbers, however I believe laszlo doesn't fully support regular expressions.

[0-9]*\.?[0-9]*

To get full functionality of regexp read the following:

Not sure if they have added full regexp support yet, these posts are abit dated.

Darn, well I guess I will need to just validate it separately...

Thanks a lot.

I tackled exactly this problem yesterday. Here's a simple class extending edittext that allows only valid numbers with a single decimal point. It works by removing any decimal point typed after the first one. It's kludgy but it does work while the user types without using any distracting messages. I'm sure there are more clever ways to do it, but perhaps this will help.

Cheers,
