Jquery 调用asp.net ajax (web service/static page method)的示例(一)---简单参数

示例一（无参数的情况） ：

$.ajax({    type: "POST",    contentType: "application/json; charset=utf-8",    url: "WebService.asmx/WebMethodName",    data: "{}",        //当被调用的page method 或则 web service 的方法是无参情况时候，需要传入空的json  对象    dataType: "json"});

示例二（简单参数的情况） ：

    $.ajax({            type: "POST",            url: "../Services/UCRender.asmx/GetControl",            data: "{'path':'~/UserControls/RSSReaderControl.ascx'}",                 contentType: "application/json; charset=utf-8",            dataType: "json",            success: function (msg) {                $('#RSSContent').removeClass('loading');                $('#RSSContent').html(msg.d);            }        });    }

对应的service 方法如下：

/// <summary>
/// Summary description for UCRender
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class UCRender : System.Web.Services.WebService
{
[WebMethod]
public string GetControl(string path)
{
Page page = new Page();
UserControl ctl = (UserControl)page.LoadControl(path);
page.Controls.Add(ctl);
StringWriter writer = new StringWriter();
HttpContext.Current.Server.Execute(page, writer, false);
return writer.ToString();
}
}
