Submitting the form with ajax(using alloy UI) i.e with out page refresh

    In rare it may happens, you have to submit the form with out refresh the page (actionURL ) and save the parameters in the DB.

   Jus Copy the below code , Here i am using alloy UI to submit the form and here not need to append any parametrs to the URL .you will get the parameters values from request parameters.


<portlet:actionURL var="formsubmissionURL" />

<aui:script use="aui-io-request,aui-node" >
Liferay.provide(window,'submitForm',
function() {
var A = AUI();
A.io.request('${formsubmissionURL}',{
method: 'POST',
form: { id: '<portlet:namespace />fm' },
on: {
success: function(){


    }
  }
  });
  });

</aui:script >

<aui:form action="#" method="POST" id="fm" name="fm" >
     <aui:input type="text" name="name"/>
     <aui:button type="submit" value="Save" />
 </aui:form>



In Class:

    String name = ParamUtil.getString("name","Venka");


That Its it done
