有没有人可以帮助我在这种情况下提供链接
<apex:repeat var="slot" value="{!liTimeSlots}">
<tr class="{!IF(ISNULL(slot.sAppointment), 'Free', 'Fill')}">
<td ><apex:outputText value="{!slot.tstart1}"/></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointment), 'Free', slot.sAppointment.name)}"/></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointment), '', slot.sAppointment.Appointment_Type__c)}"/></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointment), '', slot.sAppointment.Patient__c)}"/></td>
</tr>
<tr >
<td></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointmentOverlap), ' ', slot.sAppointmentOverlap.name)}"/></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointmentOverlap), '', slot.sAppointmentOverlap.Appointment_Type__c)}"/></td>
<td><apex:outputText value="{!IF(ISNULL(slot.sAppointmentOverlap), '', slot.sAppointmentOverlap.Patient__c)}"/></td>
</tr>
</apex:repeat>
我想仅在slot.sAppointment或slot.sAppointmentOverlap不为空时显示链接。
任何想法如何解决这个问题。

与几乎所有apex:
Visualforce标记一样,apex:outputLink
具有rendered
属性,可用于显示或隐藏它,并且可以使用合并字段/公式价值,所以你将寻找以下内容:
<apex:outputLink value="url" rendered="{!NOT(ISNULL(slot.sAppointment)) || NOT(ISNULL(slow.AppointmentOverlap))}">The link</a>
我用于一组标记元素的条件渲染的另一个技巧是将它们包装在apex:variable
标记中:
<apex:variable var="v" value="" rendered="{!ShouldThisRender}">
<!-- Some page elements -->
</apex:outputVariable>
