I want to display an error message when no records found in jquery, but the error message is not displaying.

What I have tried:

<pre lang="Javascript"> function EditApi() {

        // debugger;
        var id = $("#txtaddEmpid").val();
        var name = $("#txtaddEmpName").val();
        var salary = $("#txtaddEmpDep").val();
        var age = $("#txtaddEmpAge").val();
        $.ajax({
            url: "http://localhost:53555/api/emp/" + id,
            type: "Put",
            data: JSON.stringify([name, salary, age, id]),
            contentType: 'application/json; charset=utf-8',
            success: function (data)
            {
                Console.log(data);
                alert('Updated Successfully');
                //window.location.href = "../Index";
            },

            error: function (data)
            {
                alert('No Record Found');
            }
        });
    };

C#

public void Put(List<string> emp, int ID)
      {

          Employee tt = tst.Employee.Find(ID);
          int id = Convert.ToInt32(emp[3]);
          int id1 = Convert.ToInt32(emp[2]);


              tt.Id = id;
              tt.Name = emp[1];
              tt.Salary = emp[0];
              tt.Age = id1;
              tst.SaveChanges();



      }

..and what is the error message?

A better way of handling this is to make your Put method return false if there is no record found rather than relying on exceptions etc.

Solution 1

why don't you try HttpResponseMessage at api side? you will be easily able to return response with custom message.

Your method will be something like:

C#

public async Task<httpresponsemessage> Put(List<string> emp, int ID)
      {
 
          Employee tt = tst.Employee.Find(ID);
          if(tt == null)
          {
            return Request.CreateResponse(HttpStatusCode.BadRequest, "No Record Found");
          }
          int id = Convert.ToInt32(emp[3]);
          int id1 = Convert.ToInt32(emp[2]);
 

              tt.Id = id;
              tt.Name = emp[1];
              tt.Salary = emp[0];
              tt.Age = id1;
              tst.SaveChanges();
 
         return Request.CreateResponse(HttpStatusCode.OK, "success!");
      }

</string></httpresponsemessage>

I have used HttpResponseMessage but im unable to see any error message in the UI

Hitesh-Systematix 19-Oct-16 6:01am

have you checked response status in success/error callback? I am sure you will find the solution from diagnose "data.status".

How can i check the response??

Hitesh-Systematix 19-Oct-16 6:08am

Try this:

success: function (data)
{
console.log('success with status:'+data.status);
},
error: function (data)
{
console.log('Error with status: '+data.status);
}
