error with RegExp inside angular.toJson

Question

error with RegExp inside angular.toJson

I'm trying to do a 'like' query in mongodb. I see that's done with a regexp so I'm trying to set it like this:

$scope.clients = Client.query({
        q:angular.toJson({
            name: RegExp($routeParams.str)
        })
    });

The thing is angular.toJson function does not get any regexp: http://plnkr.co/edit/idXMT1

Is there any other way to do that?

regex
angularjs

Answer 1

From my understanding of your question, you want your JSON object to contain the regular expression as a string?

In that case, you can manually convert it to a string in the declaration, i.e:

$scope.object = angular.toJson({
    "param" : new RegExp(str).toString()
});

I finally found a solution.

The problem is using the toJon function as it does not allow any key starting with / or $ so the solution is avoiding the use of this function and just write the object as a string

$scope.clients = Client.query({
    q:'{src:{$regex:"' + $routeParams.str + '"}}'
};
