Is the term "filter" considered a reserved keyword in Angular, Javascript, or ASP.Net MVC?

When using angularJS to call an ASP.Net MVC controller from a service, I encountered an issue with one of the parameters:

$http({
    method: "get",
    url: "ControllerMethod",
    params: {
        param1: param1Value,
        pageNumber:  pageNumber,
        pageSize: pageSize,
        anythingElse: filter
    }
}).success(function (data) {
    callback(data);
}).error(function () {
    alert("Error.");
});

The controller's method signature is:

public ActionResult GetAssetDepreciationList(
     int pageNumber, int pageSize, int param1, MyFilterType filter)

Surprisingly, the "filter" parameter was always arriving as null. This was puzzling as similar methods were working fine.

After changing the parameter name from "filter" to "anythingElse":

anythingElse : filter

the issue got resolved. Could it be possible that "filter" is a reserved word in a specific framework (MVC, Javascript, or angular)?

Answer №1

Seems like the filter being used is of a complex type called MyFilterType. Check out this link for more information.

If creating a custom parser is necessary, go ahead. However, you can also retain the model (if MyFilterType is a POCO) and send the filter (in JSON format) within the body of the request instead.

In case your filter complexity increases, consider using OData. It's a simple Nuget Package that streamlines queries, has standardized parsers, offers configuration options, and seamlessly integrates with IQueryable.

Additional information such as details about MyFilterType and the actual data in :filter would be helpful.

update:

An interesting issue related to query strings and model parsing... I managed to resolve it by incorporating the following steps: (Requires System.Web.Http)

 public ActionResult GetAssetDepreciationList(
      int pageNumber, int pageSize, int param1, [FromUri] MyFilterType filter)

By merging the individual parameter names from the filter onto the params object, like so:

params: angular.extend({
                           param1: paramValue,
                           pageNumber: pageNumber,
                           pageSize: pageSize,
                        },filter)

I assumed 

var filter = {paramA:1,paramB:2,paramC:3};
