Visualforce Action Function Example.
Hi,
In this post i am giving an example of simple usage of <apex:actionFunction> tag in visualforce page to call a apex method from Java script.
Controller Class:
public class ActionFunctionCLS {
public Account
actObj{get;set;}
PageReference
prf= null;
public
ActionFunctionCLS(){
actObj = new
Account();
}
public
pagereference Saverec(){
if(actobj.Name
!=''){
insert actobj;
}
else{
ApexPages.Message myMsg = new
ApexPages.Message(ApexPages.Severity.ERROR,'Error: Please Enter Name.');
ApexPages.addMessage(myMsg);
}
if(actobj.id
!=null){
// Send the
user to the detail page for the new account.
prf = new
PageReference('/'+actobj.id);
prf.setRedirect(true);
}
return prf;
}
}
Visualforce Page:
<apex:page
controller="ActionFunctionCLS" id="pg" >
<script>
function recSave(){
var accountType =
document.getElementById('pg:fm:pb:pbs:actType').value;
alert('accountType -->'+accountType);
if(accountType != 'Prospect'){
alert('You Should Select Prospect to Save
the Record');
return false;
}
else{
saveAccount(); //this is the function name
which calls our action function from java Script.
return true;
}
}
</script>
<apex:form id="fm">
<apex:actionfunction
name="saveAccount" action="{!Saverec}" />
<apex:pageBlock id="pb">
<apex:pagemessages
></apex:pagemessages>
<apex:pageblockButtons >
<apex:commandButton
value="Save" onclick="recSave();return false;"/>
</apex:pageblockButtons>
<apex:pageblockSection
id="pbs">
<apex:inputField
value="{!actobj.Name}" id="actName"/>
<apex:inputField
value="{!actobj.type}" id="actType"/>
</apex:pageblockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
Once you select Account Type as "Prospect" Javascript method will call the <apex:actionfunction name="saveAccount" action="{!Saverec}" /> and controller method is going to execute.
That's it..
