jsf-2 - 如何将 Primefaces inputMask 限制为仅数字？

Question

我要限制p:inputMask到号码 只有 ，我尝试了以下建议的解决方案:

How to restrict an input to numbers only with PrimeFaces inputMask element

但他们都没有工作。我尝试了这两种方法:

<p:inputMask id="userNo"  maxlength="2" mask="9?9999" />

和

<p:inputMask id="userNo"  maxlength="2" >
    <pe:keyFilter regEx="/[0-9_]/i"/>
</p:inputMask>

Answer 1

我认为这种方法是正确的，但我注意到您没有输入 value inputMask 上的属性.
你试着穿上它吗？

Edit: These solutions works:

inputMaskTest.xhtml:

<h3>Input Mask:</h3>
<h:form id="form">
    <p:outputLabel value="Input Mask only number " for="userNo1" />
    <p:inputMask id="userNo1"  maxlength="2" mask="9?9999" value="#{inputMaskView.number}"/>

    <p:outputLabel value="Input Mask only Number Primeface Ext " for="userNo2" />
    <p:inputMask id="userNo2" maxlength="2" value="#{inputMaskView.number}">
        <pe:keyFilter regEx="/[0-9_]/i" />
    </p:inputMask>
</h:form>

InputMaskView.java:

@ManagedBean(name = "inputMaskView")
@ViewScoped 
public class InputMaskView {
  private String number;

  public String getNumber() {
    return number;
  }
  public void setNumber(String number) {
    this.number = number;
  }
}
