Question

I have an Ajax call to my controller action looks like this:

var m = $.ajax({
        mtype: "GET",
        url: '@Url.Action("GetBrandForValidation")',
        data: { actionparameter: value },
        async: false,
        cache: false
});

As u can see i return actionparametter to my controller and controller have to return either true or false which has to be my “m” value, but i cant get it to work. Any ideas?

Controller Code:

public virtual JsonResult GetBrandForValidation(string actionparameter)
{
    var vendorId = _service.GetVendorIdByUsername(GetUserName());
    bool k;
    var brands = _service.GetBrandsByVendor(vendorId);
    var brand = new BrandsViewModel();
    brand.BrandName = "Opret ny Brand...";
    brands.Add(brand);

    foreach (var brandsViewModel in brands)
    {
        if (brandsViewModel.BrandName == "Intet")
        {
            brandsViewModel.BrandName = "";
        }
    }

    var list = brands.Select(s => s.BrandName);
    if (list.Contains(actionparameter))
    {
        k = true;
    }
    else
        k = false;

    return Json(k,JsonRequestBehavior.AllowGet);
}

And full function code :

var checkBrands = function(value, colname) {  
    var m = $.ajax({
                mtype: "GET",
                url: '@Url.Action("GetBrandForValidation")',
                data: { actionparameter: value },
                async: false,
                cache: false

    });
    if (m == true)
        return [true, ""];
    else
        return [false, "Brand eksistere ikke"];
};

Im quite new and very awfull at javascript, so dont judge hard
