How to Pass javascript variable to Controller in MVC from View

Question

all I want to pass one javascript variable to Controller from MVC View from Form. This is my own selected text variable which I want to pass to controller so that I can retrieve and save in Database.Any help will be appreciated I am sharing the code which I want

View -->I am getting selected text value which I want to pass to controller

$(document).ready(function () { 
    $("#stateID").change(function () {
         var state= $('#stateID :selected').text();
         getCities(state);
    });
});

Now I want to pass this state variable to controller from an mvc form

@using (Html.BeginForm("Register", "Registration", FormMethod.Post))
{
    <input type="submit" value="Save" style="text-align:center"  />
}

Now, this is my controller Code which I want to retrieve

[HttpPost]
public ActionResult Register(RegisterModel Regmodel)
{
    if (ModelState.IsValid)
    {
        return View();
    }
}

Thanks @Rondles My issue is resolved now and thank you guys for ur quick resonse

Solution

You could set up a hidden field in your form for the state (I assume state is a property on your RegisterModel?) and in your stateID.change function have it assigned the value to the hidden field for it to be passed on submit.

e.g:

Hidden field in the form can be set up with (inside your begin form code):

@Html.HiddenFor(model => model.StateID, new { id = hiddenStateID" })

Then your jQuery would be (untested, this is more pseduo code to give you the idea):

$(document).ready(function () 
 {  
        $("#stateID").change(function (){
             var state= $('#stateID :selected').text();
             getCities(state);
             $("#hiddenStateId").val(state);
        });
 });

use ajax to call the controller and pass your parameters

@zaki actually I don't want to go for Ajax because I have so may other controls also and through json I don't want to send ..
