在上面的代码中，提到的javascript函数和C# webmethod的ajax调用不起作用，没有显示任何错误，也没有达到断点。 请提前帮助我谢谢!!!!!!!!!!!!

但是上面使用的是 5 个参数，但不起作用，并且在将超过 10 个参数传递给 ajax 调用时没有显示任何错误

请帮帮我... 提前致谢

您能否为查询字符串参数添加模型

public class ProjectModel
{
public int Id { get; set; }
public string CompanyCode { get; set; }
public string ProjectName { get; set; }
public string ProjectDescription { get; set; }
public string ProjectType { get; set; }
public string LocationSite { get; set; }
public string Client { get; set; }
public string Latitude { get; set; }
public string Longitude { get; set; }
public string Status { get; set; }
public string FirstLevelApprover { get; set; }
public string SecondLevelApprover { get; set; }
public string ThirdLevelApprover { get; set; }
public string userComment { get; set; }
public string CrudType { get; set; }
}

并在操作中传递模型方法

[WebMethod]
public static string SaveAndUpdateProject(ProjectModel model)
{
// your business logic
// you can access model properties by model.Id, model.CompanyCode
}

另外，在 ajax 方法中，您需要更改 obj 对象

var model= new Object();  
model.Id = $('#HdxtProjectId').val();
model.CompanyCode = $('#ddlCompanyPrm').val();
model.ProjectName = $('#txtProjectnamePrm').val();
// rest of the properties

在 Ajax 方法中，将数据更新为：

data: JSON.stringify(model),
