Disable User Selection in <h:selectOneRadio>

问题

I am trying to disable user selection in tag.

    <h:selectOneRadio id="wildcard"   value="#{NewService.isWildCard}" label="#{msg.org_IsWildCard}" readonly="true" layout="lineDirection">              
                                        <f:selectItem id="yes" itemLabel="YES" itemValue="1" />
                                        <f:selectItem id="no" itemLabel="NO" itemValue="0" />                                       
</h:selectOneRadio> 

However on my GUI I am still able to select radio button value. Please tell me what is wrong in the code..Also the BackingBean code is pretty simple..I am just passing 0 or 1 in backingBean...

Please guide me on how to disable user selection in

回答1:

This is indeed unintuitive behaviour of the JSF-generated HTML <input type="radio"> element. There are basically 2 solutions to your problem:

1. Use disabled="true" instead of readonly="true":

   <h:selectOneRadio disabled="true">
   

2. Add an onclick handler which returns false:

   <h:selectOneRadio onclick="return false;">

Use the itemDisabled attribute in your selectItems:

<f:selectItem id="yes" itemLabel="YES" itemValue="1" itemDisabled="true"/>

     <f:selectItem id="yes" itemLabel="YES" itemValue="1" itemDisabled="#{NewService.type == 1 }"/>
     <f:selectItem id="no" itemLabel="NO" itemValue="0" itemDisabled="#{NewService.type == 1 }"/>
</h:selectOneRadio>
