inputCheckbox et commandLink/commandButton ne peuvent pas fonctionner ensemble !!Comportement étrange (bug) de inputCheckbox dans le visualforce
Cas 1:
Essayez les codes.
L'action Visualforce dans celle-ci ne peut pas fonctionner.
<apex:commandLink action="{!SelectTicket}" reRender="outputPanel">
<apex:inputCheckbox value="{!ordsOptions[o]}"/>
<apex:param name="selected" value="{!o.id}" assignTo="{!selected}"/>
</apex:commandLink>
Sans
value="{!ordsOptions[o]}" dans le inputCheckbox. Le code presque identique fonctionne bien.
<apex:commandLink action="{!SelectTicket}" reRender="outputPanel">
<apex:inputCheckbox/>
<apex:param name="selected" value="{!o.id}" assignTo="{!selected}"/>
</apex:commandLink>
Cas n ° 2:
Il ne se déclenche pas l'action du tout quand ajoutez le inputCheckbox dans une autre colonne.
<apex:dataTable border="4" value="{!ords}" var="o">
<apex:column >
<apex:commandLink action="{!SelectTicket}" reRender="outputPanel">
<apex:inputCheckbox />
<apex:param name="selected" value="{!o.id}" assignTo="{!selected}"/>
</apex:commandLink>
</apex:column>
<apex:column ><apex:inputCheckbox value="{!ordsOptions[o]}"/></apex:column>
<apex:column ><apex:outputText value="{!ordsOptions[o]}"/></apex:column>
<apex:column value="{!o.Id}"/>
<apex:column value="{!o.Name}"/>
</apex:dataTable>
Il fonctionne très bien sans inputCheckbox avec commandLink:
<apex:dataTable border="4" value="{!ords}" var="o">
<apex:column >
<apex:commandLink action="{!SelectTicket}" reRender="outputPanel">
<apex:inputCheckbox />
<apex:param name="selected" value="{!o.id}" assignTo="{!selected}"/>
</apex:commandLink>
</apex:column>
<-- <apex:column ><apex:inputCheckbox value="{!ordsOptions[o]}"/></apex:column> -->
<apex:column ><apex:outputText value="{!ordsOptions[o]}"/></apex:column>
<apex:column value="{!o.Id}"/>
<apex:column value="{!o.Name}"/>
</apex:dataTable>
Les codes entiers
vf:
<apex:page controller="SelectRadio" sidebar="false">
<apex:outputPanel id="outputPanel">
<apex:form >
<apex:dataTable border="4" value="{!ords}" var="o">
<apex:column >
<apex:commandLink action="{!SelectTicket}" reRender="outputPanel">
<apex:inputCheckbox />
<apex:param name="selected" value="{!o.id}" assignTo="{!selected}"/>
</apex:commandLink>
</apex:column>
<apex:column ><apex:inputCheckbox value="{!ordsOptions[o]}"/></apex:column>
<apex:column ><apex:outputText value="{!ordsOptions[o]}"/></apex:column>

<apex:commandButton action="{!rSfdc}" value="按鍵"/>
