How to pass dynamic value in @Url.Action?

Question

I have written following jquery in my partial view:

    $.ajax({
        type: \"POST\",
        url: \'@Url.Action(\"PostActionName\", \"ControllerName\")\'

I have functions to fetch invoking action and controller names, but not sure how I can pass them in @Url.Action

Well, you could call those functions. For example if they are extension methods to the UrlHelper class:

window.location = '@Url.Action(Url.MyFunction1(), Url.MyFunction2())'

or if they are just static functions:

window.location = '@Url.Action(SomeClass.MyFunction1(), SomeClass.MyFunction2())'

If on the other hand the values that need to be passed are known only on the client you could do the following:

var param = 'some dynamic value known on the client';
var url = '@Url.Action("SomeAction", "SomeController", new { someParam = "__param__" })';
window.location.href = url.replace('__param__', encodeURIComponent(param));

UPDATE:

It seems that you are just trying to fetch the current controller and action which could be achieved like that:

@{
    string currentAction = Html.ViewContext.RouteData.GetRequiredString("action");
    string currentController = Html.ViewContext.RouteData.GetRequiredString("controller");
}

and then:

window.location.href = '@Url.Action(currentAction, currentController)';
