MVC 4 - How can I load a View using JavaScript

I am pretty new to MVC and JavaScript. I have a dropdown ('ProcessGroupRevisions') on a View and when the user selects a certain item in the drop down, I want to execute an action in a controller that will render a new view. I have the following code which is sort of stubbed out. But I know it's not right (because it doesn't work), but I'm not sure what I need to do to make it work.

        // This handles the onchange for the Revisions dropdown.
        $("#ProcessGroupRevisions").change(function () {
            if ($("#ProcessGroupRevisions").prop("value") == "-1") {
                '@Url.Action("AddNewRevision", "SetpointManagement", new RouteValueDictionary { { "processGroupId", ViewBag.ProcessGroupId } })';
            }
        });

Sorry posted accidentally before I was finished the first time.

<script>
    $(function(){
        $("#ProcessGroupRevisions").change(function () {
            if ($("#ProcessGroupRevisions :selected").val() == "-1") {
                var url = '@Url.Action("AddNewRevision", "SetpointManagement")';
                //To load the view via AJAX
                $("#GroupRevisionDetails").load(url, new {processGroupId: $("#ProcessGroupRevisions :selected").val()});
                //To load the view and replace the current page
                window.location.href = url + "?processGroupId=" + $("#ProcessGroupRevisions :selected").val();
            }
        });
    });
</script>

<select id="ProcessGroupRevisions">
    <option value="-1">-- Pick One --<option>
    <option value="1">Group Revision 1<option>
    <option value="2">Group Revision 2<option>
    <option value="3">Group Revision 3<option>
    <option value="4">Group Revision 4<option>
</select>

<div id="GroupRevisionDetails"></div>

You can try to use the jquery load method:

$('#yourContainer').load('/ControllerName/ActionName');

"yourContainer" must in this case be the ID of the HTML element which you want to use as a container for your view. You may also want to have some extra logic to avoid having that hard-coded URL to the controller there. In that case you can do something like this:

var baseUrl = '@Url.Content("~")'

$("#yourContainer").load(baseUrl + "ControllerName/ActionName");

Note that the baseUrl variable must be defined in your CSHTML file and not in a separate js file, because it must be handled on the server-side.

You can try using window.location
For eg.

window.location = "/ControllerName/ActionName";
