Parsing query string in JS to filter results

Question

I have a function here which will makes an ajax call to return data. I want to return data using 5 variables as shown to filter the data.

workarearefs, jurisidcitons and tags will be from a query string in this kind of format:

details?companyid=1&datepreset=lastmonth&jurisdictionref=3&jurisdictionref=6&jurisdictionref=18&s=1&workarearef=2&workarearef=11&workarearef=14

datapreset and companyid is coming from a view which works.

How can I parse the query string into the ajax call then I would like to use linq to filter the results with the refs in the url?

JS:

taxiBriefingShow.click(function (e) {
    e.preventDefault();
    if (!loaded) {
        var companyId = $(this).data('companyid');
        var workAreaRefs = // from querystring, 0 to many: workarearef=1&workarea=2&workarea=99 etc
        var jurisdictions = $(this).data("jurisdictions"); // from querystring, 0 to many: jurisdiction=1&jurisdiction=2&jurisdiction=99 etc
        var tags = $(this).data("tags"); // from querystring, 0 to many: tagref=1&tagref2=2&tagref=99 etc
        var preset = $(this).data("preset");

        var filterModel =
        {
                WorkareaRefs: workAreaRefs,
                Jurisidctions: jurisdictions,
                Tags: tags,
                Preset: preset
        }

        $.ajax({
            data: JSON.stringify(filterModel),
            url: '/api/track/v1/taxibriefing?companyId=' + companyId + '&preset=' + preset + '&workarearefs=' + workAreaRefs + '&tags=' + tags + '&jurisdictions=' + jurisdictions, 
            async: false,
            success: generateTaxiLists
        });
    }
    togglePanel();
});

I am setting properties to these with these applied filters in the model:

    public IList<TrackFilterGenericRef> Workareas { get; set; }

    public IList<TrackFilterGenericRef> Jurisdictions { get; set; }

    public IList<TrackFilterGenericRef> Tags { get; set; }

To set these properties in the API Controller: The part from var workareas = workareaRefs.Split(',') is wrong.

    [HttpPost]
    public async Task<TaxiContainerModel> Post([FromBody] WidgetConfigurationRequestVM data, int companyId, string workareaRefs, string tags, string jurisidctions, DatePreset preset)
    {

        if (!IsCompanyAllowed(data.CompanyId))
        {
            throw new HttpResponseException(HttpStatusCode.Forbidden);
        }

        var MLId = GetMLID(data.CompanyId);
        if (string.IsNullOrWhiteSpace(MLId))
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }

        if (data.Configuration.IsNullOrEmpty())
        {
            throw new HttpResponseException(HttpStatusCode.BadRequest);
        }

        var Workareas = workareaRefs.Split(',');
        var Tags = tags.Split(',');
        var Jurisidctions = jurisidctions.Split(',');

        var r = new TrackDataFilter
        {
            DatePreset = preset,
            Workareas = new List<TrackFilterGenericRef>
            {
                new TrackFilterGenericRef
                {

                    Ref = 2, Type = Enums.ContentTypes.Workarea
                }
            },
        };

        return await taxiBriefingService.GenerateBriefingAsync(data.CompanyId, MLId, data.Notes == null? "" : data.Notes, LexUser.FirmRef, data.Configuration.Select(x=>( x.Row, x.Col, (TaxiWidgetSize)x.Size, (TaxiWidgetType)x.Type)), r);
    }
}

workareas, jurisdictions, and tags should contain the values in workareaRefs/jurisdictions/tags from query string stored in the variable named r. Can anyone help me achieve this?

Your title and your tags don't really match. If you're trying to parse query strings in JS, that question has been asked before: [How can I get query string values in JavaScript?](https://stackoverflow.com/q/901115). But you don't have the `javascript` tag there, so should we assume you actually want to get the items from the query string in your API method? If so, there's a `[FromQueryString]` attribute you can apply to arguments. — Heretic Monkey, Jul 30 '18 at 15:59
There's no data attribute being set for workAreaRefs in your ajax call. You have commented out text. — , Jul 30 '18 at 16:05
