Hello,

 

Please use the following code. In the rerender property of actionFunction please specify the id of section which you want to rerender. 

 

VF Page - Action function
<apex:actionFunction name="sendTimeStamp" action="{!sendTimeStamp}" rerender="pb">
    <apex:param name="x" value="" assignTo="{!timeStampValue}" />
</apex:actionFunction>

javascript code:

timeStamp = Number(new Date());
          sendTimeStamp(timeStamp);

controller code:

public class TestController{
public string timestampValue{get;set;}

public TestController(){
timeStampValue = '';
}
public void sendTimestamp(){
system.debug('timestampValue' + timeStampValue);
}
}

If you check the forum you will find many readymade code for this purpose:-

 

I found this 1 just check  and compare what are u doing different:-

 VF Coded:-

<apex:page controller="OurTest">

<apex:form>

<apex:actionFunction name="ShuffleByID" action="{!ShuffleByRecordID}" rerender="out"/>  

                    <apex:outputPanel id="out">

                                         <apex:pageBlock >                                                                                                                                                                                                                  

                <apex:pageBlockTable value="{!studentListLongArr}" var="enrollment" rendered="{!EnrollmentListSize > 0}">          

                     <apex:column >

                       <apex:pageBlockTable value="{!enrollment.Registered_Student__r}" var="stulist">

                      

                          <apex:column >

                                         <apex:facet name="header">

                                                             <apex:commandLink onclick="ShuffleByID();return false;" action="{!doSort}" rerender="out">Record ID

                                                                                 <apex:param name="sortField" value="{!stulist.Name}" assignTo="{!YourName}"/>

                                                             </apex:commandLink>

                                         </apex:facet>

                                         <apex:outputLink value="{!stulist.id}" target="_top">{!stulist.Name}</apex:outputLink>

                          </apex:column>

</apex:form>                                                                                                                   

</apex:page>                                                                                             

 

Controller Code:-

 

public class OurTest()

{

                    public string YourName {get;set;}

                                         public OurTest()

                    {

                    system.debug('++++++' +YourName);

                    //now you will get the value foYourName which you are passing from VF param tag.

                    }

                    // Rest of the code can be put here

 

}

 Hi,

           You can pass the variable to controller by using the below code snippet.

            Below is the sample code to work around on this.

 

           <apex:inputhidden value="{!Propval}" id="hdnobj"/>

                <script>

                                var crtUrl = "{!$CurrentPage.URL}";

                                document.getElementById('pageid:formid:hdnobj').value = crtUrl;

           </script>

 

Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.
