Question

JSP/JQuery call:-

$.ajax({
  url: "ApplyCouponCode",
  type: "POST",
  data: {couponCode: $('#PaymentMethod_couponCode').val()},
  dataType: "json",
  error: function(){
      alert('Error');
  },
  success: function(data){   
   alert('SUCCESS');
   $('#spanValidatedCoupon').text('Is coupon valid? ' + data.couponIsValid + ' couponAmount = ' + data.couponAmount);
  }

});

Action Class:

 public String applyCouponCode() throws Exception {
    if(logger.isDebugEnabled()){
        logger.debug("data: couponCode '" + couponCode + "'");    
    }
    return SUCCESS;
}

The Action class method [applyCouponCode] is invoked. But couponCode is null.. please advise. couponCode has public getter/setter methods .. what else do i need to do?

Answer 1

I think your action method should take couponCode as a parameter. Assuming couponCode is type string, your action method should look something like this:

public String ApplyCouponCode(string couponCode)

Hope this helps.
