Restrict (Prevent) Form submission based on condition using jQuery in ASP.Net MVC

Hi ,

How to restrict form submit on jquery

On submit if dropdown has value is "1" then it will validate all the fields and will pass values to my controller method - Employee master

else if dropdown value is 2 then also it should validate empty fields BUT instead of going to controller it should show any alert.

NO FURTHER MOVEMENT TO CONTROLLER. Is it possible. Please help 

@using (Ajax.BeginForm("EmployeeMaster", "Home", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "divEmp" }))

$(".next").on('click', function () {
    if ($("#ddlstate").val() == 2) {
        if (("#form").valid()) {
            alert("hi");
        }
        else {
            //nothing
        }
    }
});
