Regular Expression to make Text Field only hold 0-9 is allowing non numeric

Hello,

I need a field in which a user is limited to a 3 digit entry which allows the numbers 0-9.

Currently I am using a text field as my object on my form, so I can limit the length to three characters.

I have looked into regular expressions in order to do what I want, but the problem is that I still can enter ".", "-", and "-".  That's the numpad Decimal, numpad Minus, and the dash keys.  I am unsure why these are allowed, but I need them to not be, as it allows a user to enter a negative or a decimal number into the field.  I imagine something isn't quite right with my regex or how I'm applying it.

If there's a better way of going about this, I'm all ears.

    Hi,

    1). Using Number Field

    For your requirement use XTYPE as numberfield. Add property to that node/field as maxValue.(Best Approach )

    Example:

    <limit jcr:primaryType="cq:Widget"
      fieldLabel="Limit"
      name="./limit"
      maxValue="9"
      xtype="numberfield"/>

    2). Using Regex.

    <limitjcr:primaryType="cq:Widget"
      fieldLabel="Limit"
      name="./limit"
      regex="/[0-9]{1}$/"
      regexText="Enter 0-9 values only."
      xtype="textfield"/>

    Why are you not using a numeric field and setting the Maximum Number of Digits to 3?

      ^(0|[1-9][0-9]*)$ this for two digit between 0 to 9 and also allow 0

      ref: Regex pattern for numeric values - Stack Overflow

      it think  you can try ^(0|[1-9][0-9][0-9]*)$

        HI,

        1). Using Regex

        below example will allows 0-99 values only.

        it will match your requirement.

        <limit jcr:primaryType="cq:Widget"

          fieldLabel="Limit"

          name="./limit"

          regex="/^([0-9]{2}|[0-9]{1})$/"

          regexText="Enter 0-99 only.Number's only"

          xtype="textfield"/>

        2). Using numberfield

        you can free to use Number field as XTYPE. it works better for you.

        If you give maxValue as 99. that field allow 0-99 values only.

        Example:

        <limit jcr:primaryType="cq:Widget"

          fieldLabel="Limit"

          name="./limit"

          maxValue="99"

          xtype="numberfield"/>

        Thanks.

          As mentioned above best approach is to use the numeric field. If server is 6.3 onwards then there is a property (Maximum Number of Digits) to set the maximum no. of allowed digits in numeric field that can control the limit of entered digits.
