ASP.NET MVC transfer data from controller to view with viewmodel

Question

In my controller I have

public ActionResult Index()
{
    //...
    //...
    var viewModel = new IndexViewModel()
    {
        MTohum = mTohum,
        STohum = sTohum,
        BTohum = bTohum,
        TKota = tKota,
        KKota = kKota,
        BKota = bKota,
    };
    //return Content("tkota : " + tKota.ToString() + " kkota : " + kKota.ToString() + " bkota : " + bKota.ToString());
    return View(viewModel);
}

When I remove comment and return Content() I can see that values are not null.

On the view side:

//..html codes..//

<script>
    $(document).ready(function () {
        alert(@Model.TKota);
        alert(@Model.KKota);
        alert(@Model.BKota);
        alert(@Model.TKota + " " + @Model.KKota + " " + @Model.BKota);
    });
</script>

My problem is: 1st, 2nd and 3rd alerts showing right info but when I trying to take all info in one alert like 4th, I can get @Model.TKota, @Model.KKota but I can't get @Model.BKota value.

Consequently I can't use @Model.BKota in the following lines.

alert("@Model.TKota + " " + @Model.KKota + " " + @Model.BKota); looks like a syntax error,would occur due to the opening " not being closed. Try this: alert(@Model.TKota + " " + @Model.KKota + " " + @Model.BKota); — Stephen Byrne

Sorry I edited my code.Its not about syntax error.Alert1 shows "100", alert2 shows "200", alert3 shows "300" but alert4 shows "100 200 " instead of "100 200 300". — Berkan Toptaş

Your last alert is badly formatted, it should look like this

alert('@Model.TKota @Model.KKota @Model.BKota');

See the following fiddle

@BerkanToptaş in that case you don't have any value in BKota of the viewmodel, what's in the bKota variable? You could see in my fiddle that this is working.

I solved problem by casting int from double.bKota variable is type of double so after I cast it to int it worked.I think there were some issues about floating numbers..

The clue is that you are not able to work with the variables after that statement, this usually means the parser has choked on something due to a syntax error.

alert("@Model.TKota + " " + @Model.KKota + " " + @Model.BKota); looks like a syntax error would occur here due to the opening " not being closed.

Try this:

alert('@Model.TKota @Model.KKota @Model.BKota');

That would not work if TKoda etc are anything else than numeric values
