JQUERY ajax passing value from MVC View to Controller

Question

What I want is to pass the value of txtComments from View (using jquery/ajax) to Controller.

The problem is the ajax/jquery doesn't accept script tags as string. Meaning, when I input any script/html tag in the txtComments the ajax goes to the error function and not being able to go in the controller.

Here is the jQuery:

        $('#btnSaveComments').click(function () {
            var comments = $('#txtComments').val();
            var selectedId = $('#hdnSelectedId').val();

            $.ajax({
                url: '<%: Url.Action("SaveComments")%>?id=' + selectedId + '&comments=' + escape(comments),
                type: "post",
                cache: false,
                success: function (savingStatus) {
                    $("#hdnOrigComments").val($('#txtComments').val());
                    $('#lblCommentsNotification').text(savingStatus);
                },
                error: function (xhr, ajaxOptions, thrownError) {
                    $('#lblCommentsNotification').text("Error encountered while saving the comments.");
                }
            });
        });

Here is the controller:

        [HttpPost]
        public ActionResult SaveComments(int id, string comments){
             var actions = new Actions(User.Identity.Name);
             var status = actions.SaveComments(id, comments);
             return Content(status);
        }

I also tried $('#txtComments').serialize() instead of escape(comments) but still the same.

Try using the data option of the $.ajax function. More info here.

$('#btnSaveComments').click(function () {
    var comments = $('#txtComments').val();
    var selectedId = $('#hdnSelectedId').val();

    $.ajax({
        url: '<%: Url.Action("SaveComments")%>',
        data: { 'id' : selectedId, 'comments' : comments },
        type: "post",
        cache: false,
        success: function (savingStatus) {
            $("#hdnOrigComments").val($('#txtComments').val());
            $('#lblCommentsNotification').text(savingStatus);
        },
        error: function (xhr, ajaxOptions, thrownError) {
            $('#lblCommentsNotification').text("Error encountered while saving the comments.");
        }
    });
});
