Hi,

Copy the below code .

You need to call doAdd() method inside the java script method with parameter

 

 

<apex:page controller="AddController" id="thePage">
<apex:form id="theForm" >
<apex:pageBlock id="theBlock" >
<apex:inputText id="test" value="{!tex1}"/>
<input type="button" value="Click" onclick="doAd()"/>
</apex:pageBlock>

<apex:outputPanel id="out">
<apex:outputText value="{!res}"/>
</apex:outputPanel>
<apex:actionFunction name="doAdd" action="{!doAdd}" reRender="out" >
<apex:param name="firstParam" assignTo="{!res}" value="" />
</apex:actionFunction>
</apex:form>
<script type="text/javascript">
function doAd(){
var a = document.getElementById('thePage:theForm:theBlock:test').value ;
doAdd(a);
}
</script>
</apex:page>

Instead of calling "doAd" call "doAdd" from your command button

HI

can you tell me why do you want to do add function by using javascript and and action function?

This is not necessary.

It can be easily done by using simply commandbutton.

for example 

<apex:commandButton value="Click"  action="{!doAdd}" rerender= "out"/>

 

If you want to invoke through javascript then , you add this line inside java script function.

<script>
function doAd()
{
var a = document.getElementById('{!$Component.tex1}').value

doAdd();
}
</script>

 

 

If this post helps you give kudos and accept it as solution
