Ajax call not working with web method

Question

I need to call a web method from Ajax call. See the below code which I'm using to make the Ajax call

$.ajax({
    type: "POST",
    url: '<%= ResolveUrl("WebForm1.aspx/CampaignData") %>',
    data: '{"CampName":' + params + '}',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (str) {
        // Handle success
        alert("Success call");
    },
    error: function (xhr, textStatus, errorThrown) {
        // Handle error
        alert("Fails");
    }

});

My web method is:

[WebMethod]
public static string CampaignData(string CampName)
{
    return CampName;
}

What config changes need to be done to use Ajax in .Net4.5

I am using .Net 4.0 after change the flowing thing it started hitting the web method break point. Inside ~/App_Start/RouteConfig.cs change:

settings.AutoRedirectMode = RedirectMode.Permanent;

To:

settings.AutoRedirectMode = RedirectMode.Off;

(Or just comment the line)

Also if friendly URLs are enabled you need to change

url: "ConsultaPedidos.aspx/GetClients",

To:

url: '<%= ResolveUrl("ConsultaPedidos.aspx/GetClients") %>',

Hope this help somebody else
