p:keyFilter not working as expected in Firefox

问题

I'm able to enter both the digits and special characters for the p input text.

How to restrict the field that can accept only digits? in all the browsers?

<p:message for="longitude" display="text"><p:autoUpdate/></p:message>
<p:inputText id="longitude" maxlength="18" style="width: 50%;" value="#{areaMB.longitude}">
<p:keyFilter regEx="/[0-9]/i" />
</p:inputText>

Browser Chrome Version 81.0.4044.113 (64-bit) - Only Digits are being able to enter in the field
Browser IE Version 11.0.9600 - Only Digits are being able to enter in the field

Problem But through Fire Fox

Browser Fire Fox 75.0 (64-bit) - Digits and Special characters are being able to enter in the field /

How to restrict the field that can accept only digits? in all the browsers?

This KeyFilter Firefox issue was fixed in PrimeFaces 8.0: https://github.com/primefaces/primefaces/issues/5110

If you really need to restrict input to digits you can use p:inputNumber like this.

<p:inputNumber id="longitude" 
               maxlength="18" 
               style="width: 50%;" 
               value="#{areaMB.longitude}" 
               decimalPlaces="0"
               minValue="0" />

Remove minValue if you want to allow negative numbers.
