ajax, jquery and web method in asp.net

I see, client side : dataType : "json"
and server side : ..., ByVal EsName As String) As String

Leakim971 I changed the server side code to this:

    Public Shared Function SendEsError(ByVal name As String, ByVal fromEmail As String, ByVal subject As String, ByVal msg As String) As String

        Return name

    End Function

in the client side it is json, so

can you help me?

I think this line is the problem:

console.log(r.name);

could you expose your server to internet ? so I can test your page ?

try :
console.log(r.d);

this is from my own local server

for the success :
success: function(r) {
     console.log(r.d);
    alert( JSON.stringify(r.d) );
},

i tired console.log(r.d);

still undefined

good suggestion, I will try it now

I will show a screen shot attach

this is the other screen shot

still undefined....sigh

you get a nice response.
where do you get "undefined" ?
To display the name, just use :

success : function(r) {
    console.log( r.d.name);
},

Select allOpen in new window

I will try that, ahhh did see my 2nd screen shot?

now I got this error:

default?cat=994:305 Uncaught TypeError: Cannot read property 'name' of undefined

what did you change after the first screenshot ? the code was right

I did this:

alert(JSON.stringify(r.d.name));

thats it

in the first screenshot this alert worked fine, that why you see the popup
and the next screenshot show the result did not come fine anymore

screen shot again
scrn3.jpg

next screenshot show the result did not come fine anymore

why? thats my question

I don't see the beginning of your success function anymore
why do you place the console.log or alert after all your code ?
put it just after the success and show me (post the code) you currently have + screenshot

here it is again:

Select allOpen in new window

I will try this

put it just after the success

this is the screen shot

its still doing it, sigh..............

Try this : console.log(typeof r);

ok i will right now

not sure what happen after #41780582
you said you add : alert(JSON.stringify(r.d.name));
but this is not the issue that stopped to return you a valid JSON, you change something else

instead of saying undefined it says object

cool. let's see it with the following :

console.log( JSON.stringify(r) );

with this code:  console.log(typeof r);

no, replace the previous code, we don't need it anymore.
it was just to check the type of the object returned.

now it says:

{"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}

with this code:

console.log(JSON.stringify(r));

leakim971 do you have skype?

I modified the server side code to this

    <WebMethod()>
    Public Shared Function SendEsError(ByVal GenName As String) As String

        Return GenName

    End Function

Select allOpen in new window

btw

this message means I don't have permission and i changed the web.config as well

message: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}

web.config:

  <authorization>
        <allow users="*"/>
      </authorization>

Still the same message

now I changed the RouteConfig.vb

settings.AutoRedirectMode = RedirectMode.Off but with this code now I have a 500 error so I change it back like this

settings.AutoRedirectMode = RedirectMode.Permanent

now I get the same message:
{"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}

this is driving me crazy

ok I switched to .asax file instead and it works

thanks for help anyway

I did with .asmx instead and it works beauitfully, thank you anway

i will show you this is the server side code:

   <WebMethod()>

But now I have another question what I want to do is reload the comments section its a <asp:repeater but I don't want the page reload only the section, how can I do that.

This is the client side code:

                    $("#pstcmt").click(function () {
                //window.location.reload();
                var Cmt = document.getElementById("<%: Txtcomment.ClientID %>").value;
                var datacmt = "{'comment':'" + Cmt + "', 'EsId':'<%: HttpContext.Current.Request.QueryString("cat") %>','uname':'<%: Context.User.Identity.Name  %>'}"
                //alert(datacmt);
                console.log(datacmt);
                var overcmt = '<div id="overlay">' + '<div id="loading">Loading<br /><img src="../images/ajax-loader.gif">' + '</div></div>';
                $(overcmt).appendTo('#pstcmtES').hide().fadeIn('slow');

                        $('#overlay').remove();

                        if (r.d == "comments are required") {

                            $('#ErrorCmt').hide().html('<h1><span>Error ' + $.parse(r.d) + '</span></h1>').fadeIn(925);

I tired everything with no luck

sort of like this:

http://www.codingfusion.com/Post/Jquery-JSON-Add-Edit-Update-Delete-in-Asp-Net

Assuming that the comments section is the tmnescortscomments you're speaking of and it actually corresponds to a DIV in the emitted HTML you should have the basis for what you need. I don't see your JavaScript bind() function (on line 35) so I don't know what it does. Unless it has code to manipulate tmnescortscomments then that bind() isn't going to do what you think.

i got it guys thanks
