这是Encosia.com提供的示例（我添加了一个form参数）。您不需要访问Page.Form-您可以改用方法参数。

代码隐藏

public partial class _Default : Page 
{
  [WebMethod]
  public static string GetDate(string someParameter)
  {
    return DateTime.Now.ToString();
  }
}

Java脚本

$(document).ready(function() {
  // Add the page method call as an onclick handler for the div.
  $("#Result").click(function() {
    $.ajax({
      type: "POST",
      url: "Default.aspx/GetDate",
      data: {someParameter: "some value"},
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(msg) {
        // Replace the div's content with the page method's return.
        $("#Result").text(msg.d);
      }
    });
  });
});
