Hi friends, I have small doubt in ajax function in asp.net

I have one ajax function which is called on Page Load of Site1.Master so that I can use that result out come from the function in all pages that inherit from site1.master.

So I have placed that ajax function in separate js file and included that file in my site1.master at first place before other js files to inculde.

When that site1.master loads (most probably after the user login) I am able to go to the function, but I am unable to go to either "Success" or "error" functions. so I have added a attribute "async:false". still the problem is persists.

Please any one can help me.

Here is my ajax code in ap.js file

C#

var AllItems = new Array();

function GetAllItemsOnLoad() {
    var aid = 1;
    var param = '{"AgencyId":"' + aid + '"}';
    try {
       $.ajax
        ({
            type: "POST",
            async: false,
            contentType: "application/json; charset=utf-8",
            url: WebSvcUrl + "/GetAllItems",
            data: param,
            dataType: "json",
            success: OnSuccessGetAllItemsOnLoad,
            error: OnFailOfGetAllItemsOnLoad
        });
    }
    catch (err)
    { alert("Unable to get the data, Please Try again"); }
} // of Get All Items

function OnSuccessGetAllItemsOnLoad(msg) {
    try
    {
        if (msg.d != null)
        {
            AllItems = msg.d;
        }
        else
        {
             alert("Unable to retrive data, Please Try again");
        }
    }
    catch (err)
    { alert("Unable to get the data, Please Try again"); }
} // on func succ get all items

function OnFailOfGetAllItemsOnLoad(request, status, error) {
    $("#lblErrIname").html("Unable to get the data, Please Try again");}

Here is the code I am calling in my site1.Master page

  if (LoginUser == 3)
 {
            ShowAdminDiv();
            GetAllItemsOnLoad();
 }
 

Please any one Could tell me where I am wrong.

Thanks and Regards
Ganesh

When you say 'on page load' you mean inside the aspx, in javascript, right ? Have you added some alerts or debugged the code in chrome to see what's happening and if the call is made ?

Ganesh KP 13-Dec-12 22:33pm

Yes it is on page load using javascript i.e $(document).ready(function())....not only I am using this function on page load but also in some Onclick events for HTML buttons. in either way I am unable to go to either success or error functions but when I keep a break point at the start of the fun yes, the controls is going to the pass the break point. and another problem is that it is working only in some browsers, I dont understand why this is happening and I am getting doubt whether the procedure that I followed is correct or not to call a web service using ajax in javascript.

Have you used chrome or firebug to check that it is actually making a POST request to the server and that it is getting a response? If so, what is the server response?

How can we know whether a response or request is happened? is this is possible with firebug huh?

Hello, my be you have missing the parameter passing

VB

success: OnSuccessGetAllItemsOnLoad,
            error: OnFailOfGetAllItemsOnLoad

you can try the correct code like this

VB

success: OnSuccessGetAllItemsOnLoad(response),
            error: OnFailOfGetAllItemsOnLoad(msg)

JavaScript

var AllItems = new Array();
            function GetAllItemsOnLoad() {
                
                var aid = 1;
                var param = '{"AgencyId":"' + aid + '"}';
               
                      $.ajax({
                            type: "POST",
                            url: "DocumentUpload.asmx/GetAllItems",
                            data: param,
                            contentType: "application/json; charset=utf-8",
                            dataType: "json",
                            success: function (response) {
                                alert(response.d);
                            },
                            failure: function (msg) {
                                alert(msg);
                            }
                        });

                } // of Get All Items
