Hi Maahi,

 

Use the rerender attribute in the commandButton.

(For example : <apex:commandButton value="Save" onclick="javascript&colon; xyz()" rerender="specify the id of the part you wish to display") />

This will prevent refreshing of the page.

 

 

Hope this works for you.

command button will refresh the page,

onclick you are just rendering some other section,

Then why you are not using simple HTML button , and call Javascript  function

It will not refresh your page

 

Hope will help you

 

Thanks,

Hello Maahi;

Try adding "return false;" at the end of your buttons onclick event as below.

 

 

<apex:commandButton value="Create Time Table" onclick="Function();return false;"/>

I have tested the same code in my org.

Do the changes marked in red as below and this will definitely work.

 

 

<apex:page controller="TimeTable" sidebar="false">
 <script> 
        
    function Function()
    {   
         document.getElementById('idSpan').style.display = 'block';
         return false; // add here return false
                
    }
 </script>
<apex:form >
<apex:outputPanel id="test123"> 
<apex:pageBlock title="Time Table">
<apex:pageBlockButtons location="bottom">
<apex:commandButton value="Save" action="{!save}"/>
<apex:commandButton value="Cancel" action="{!cancel}"/>
</apex:pageBlockButtons>
<apex:pageBlockSection >
<apex:inputField value="{!timetable.Date__c}"/>
<apex:inputField value="{!timetable.Class__c}" />
<center><apex:commandButton value="Create Time Table" onclick="javascript&colon; return Function();" rerender="opDummy"/></center>
</apex:pageBlockSection>
<span id="idSpan" style = "display:none">
<apex:pageBlock >
<apex:pageBlockSection title="Time Table" columns="1" id="Details">
<table>
