Question

每当我管理比绍的ASPX页面时,我都收到内部服务器Error。这是我从“网吧”中复制的一件事。

ASPX 页: 1

Answer 1

I think you just need to decorate those methods with [WebMethod] like so:

[System.Web.Script.Services.ScriptService]
public class GetVendor : System.Web.Services.WebService {

    [WebMethod]
    public int GetVendorDetails(int id)
    {
        return id;

    }
}

“K”这一回答是头部的一个boot子......如果你具体说明数据表,数据以及网络服务中的名称必须相同。感谢每个人的帮助/选择。 ——

Answer 3

询问它应当如何工作,

function CallService() {

    var CatID = {"ID": $( #txt_id ).val()}
    $( input[type=button] ).attr( disabled , true);
    $("#CustDetails").html(  );
    $("#CustDetails").addClass("loading");
    $.ajax({
        type: "POST",
        url: "AdvService.asmx/GetCtcDetails",
        data: JSON.stringify(CatID ),,
        contentType: "application/json; charset=utf-8",
        dataType: "json",         

        success: OnSuccess,
        error: OnError
    });

}

Answer 4

你可以使用VS。在援引“雅氏”呼吁时,看到哪一部法典正在运行(如果有的话)。这是开始解决“内部服务器电子”麻.问题的一个良好地方。

其次,如果你使用Firebug(网络开发中的“i plug”),你应明确加以核对,帮助在更大程度上用麻省电话进行脱浮。更具体地讲到你的调查,看看看您的<编码>GetVendorDetails方法是否更像这种帮助。

using System.Web.Script.Services;
using System.Web.Services;
using System.Web.Script.Serialization;

...

[WebMethod]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)]
public string GetVendorDetails(string Id) {
  // do your processing here to get your result
  return new JavaScriptSerializer().Serialize(yourObjectInstanceToBeJsonSerialized);
}
