Tips on sending parameters to a web method using prototype

I've encountered an issue while trying to pass a parameter to a web method. Despite removing the parameters from both the method and prototype ajax request, everything works fine. However, when I attempt to use a parameter, it fails to work. Here is my code snippet:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/prototype/1.7.1.0/prototype.js"></script>
<script>

    var xRequest = new Ajax.Request('PrototypeTest.aspx/Test', {
        method: 'post',
        parameters: { "id": 'asdf' },
        contentType: 'application/json; charset=utf-8',
        onSuccess: function (val) {
            var brands = val.responseText.evalJSON().d.evalJSON();
            brands.each(function (brand) {
                alert(brand.Name);
            });
        },
        onerror: function (val) {
            debugger;
            alert('hata');

        }
    });
</script>

 [WebMethod]
    public static string Test(string id)
    {
        List<brand> brands = new List<brand>();
        brands.Add(new brand()
            {
                Name = "BMW",
                IsActive = true
            });

        var json = new JavaScriptSerializer();
        return json.Serialize(brands);
    }

Can anyone spot where I might be going wrong?

Answer №1

Although I can't say for sure if this is the right approach, it definitely resolved my issue:

 Using Ajax.Request('PrototypeTest.aspx/Test?prod=1', {
    // Your code here
});  

By passing parameters as a query string, the problem was successfully tackled.
