Visualforce Remoting: Parameter length does not match remote action parameters

What does it mean? 

 

I am trying to do remote javascripting in visualforce. Controller is setup, but when I call function, javascript debugger in chrome gives me this error... function does not take any parameters and simply returns 'Hello' string when is called... Any help would be great.

Use your one i tested with remotetest, forgot to change

 

jQuerySampleController.closeOpportunity(handleCloseOpportunity);
      
      function handleCloseOpportunity(result, event) {
          if(event.type == 'exception') {
              alert(event.message);
          } else {
             var  msg = result;
              alert(msg);
          }
      }

Could you please share your code

This is the script part 

 

message = jQuerySampleController.closeOpportunity();
                
               alert( message );

 this is the controller

 

global class jQuerySampleController{

@RemoteAction
    global static String closeOpportunity() {
    
    return 'Hello';
    
    }    
    
}

Do it like this

 

 

remoteTest.closeOpportunity(handleCloseOpportunity);
      
      function handleCloseOpportunity(result, event) {
          if(event.type == 'exception') {
              alert(event.message);
          } else {
             var  msg = result;
              alert(msg);
          }
      }

 

This is a callback function which handels the output of method invoke through js remoting.

Your welcome ,

Even though there is no document but thats a standard way of doing any ajax call, if you have in touch of .net you will see smilar in c#. even you will see similar syntax in Apex webservice methods those are invoked via java script.
