p:keyFilter在Firefox中无法按预期工作 [英] p:keyFilter not working as expected in Firefox

问题描述

我可以为p输入文本输入数字和特殊字符.

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

如何限制只能接受数字的字段?在所有浏览器中?

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>

浏览器Chrome版本81.0.4044.113(64位)-只能在该字段中输入数字
浏览器IE版本11.0.9600-只有数字可以在字段中输入

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

问题 但是通过Fire Fox

推荐答案

此KeyFilter Firefox问题已在PrimeFaces 8.0中修复: https://github.com/primefaces/primefaces/issues/5110

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

如果您确实需要将输入限制为数字，则可以使用p:inputNumber这样.

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" />

如果要允许负数，请删除minValue.

Remove minValue if you want to allow negative numbers.
