I'm using <apex:actionFunction> and my page is reloaded. I don't use reRender attribute and I'm wondering if there is a way to prevent page reloading.

Maybe there is a special value to set to reRender ?


Here is my code :

  <apex:page controller="myController">
      <apex:commandButton value="save" onclick="save()"/>

      <script type="text/javascript">

          function save(){
              // Some code
              // Some code

      <apex:form >
          <apex:messages />
          <apex:actionFunction name="myMethod" action="{!controllerMethod}">       
              <apex:param name="param" value="" />

And my controller :

 public String controllerMethod() {
     String values = Apexpages.currentPage().getParameters().get('param');
     system.debug('Values : ' + values);

     return values;

If you call the action function just put return false; to the end of the call:

<apex:actionFunction name="myFunction" action="{!someMethod}" /> 

<a href="#" onclick="myFunction(); return false;">Click me</a>

Or based on your code:

<apex:commandButton value="save" onclick="save(); return false;"/>
  • I tried your tip but it doesn't work. I post some code.

What should work in most cases is to just add reRender="", or as Neo suggests rerender="none". It doesn't really matter what is put between the "" as long as it doesn't match the name of any elements on the page.

The way the <actionFunction> tag works is that if there is no reRender attribute defined it refreshes the entire page, but if there is a reRender attribute it only refreshes the elements defined in the tag. So adding reRender="" will lead to nothing being re-rendered, whereas reRender="none" or reRender="false" will re-render the element whose id is none or false, respectively.

Visualforce doesn't strictly enforce that the ids specified in your reRender exist on the page. As a result if that id doesn't exist, it will simply be ignored.


In this tag:

<apex:actionFunction name="myMethod" action="{!controllerMethod}">

Add reRender="false" so it ends up being:

<apex:actionFunction name="myMethod" action="{!controllerMethod} reRender="false">

This worked for me!

  • It also works to use reRender="none"

  • Nope. It doesn't work for me and according to the docs this is not what the reRender attribute is for.

  • This didn't work for me as well. I guess there are no false/true values for rerender. It just picks up for checking the component id and then proceeds with the rerendering. Jan 15, 2023 at 7:28
