using jquery inside a javascript function.

Hi,

I have the following javascript function which is inside an include file within my asp.net website.

function saveTrackingData()
{
//debug to make sure we are hitting this function, and we are!
alert("hey");

//Test call to get call to .net working
$.ajax({
type: "POST",
url: "~/Index.aspx/HelloWorld",
data: "{}",
contentType: "application/json",
dataType: "json",
success: function (msg) {
// Replace the div's content with the page method's return.
alert(msg);
}
});

What I am basically trying to do is within the javascript file use jquery to call my helloworld function just as proof of concept....

I'm fairly new to javascript so am not sure if this is along the right lines...

Can someone advise as this isn't working?

Thanks in advance.

url: "~/Index.aspx/HelloWorld",

is this jax call is hitting this asp page.

Since the url you assigned is a relative path, make sure that the URI http://yourdomain/~/Index.aspx/HelloWorld exists.

chaituu:I presume you are asking if the hello world function is on the current page?

Yes the page we are on is index.aspx...

And yes stringray it does exist....
<WebMethod(EnableSession:=False)> _
Public Shared Function HelloWorld() As String
Return "Hello: " & DateTime.Now.Millisecond
End Function

$.ajax({
type: "POST",
url: "~/Index.aspx/HelloWorld",
contentType: "application/json",
dataType: "json",
success: function (msg) {
// Replace the div's content with the page method's return.
alert(msg);
}
error: function (msg) {
alert("error");
}

});

use firebug net tab to see what your code is trying to access

I think you should remove the ~/ from the url to make it work

something to add....

index is at the root level... the js file which gets included is in a folder "js" which is in the root folder...

StingRaY

Use this

url: "/Index.aspx/HelloWorld"

instead of

url: "~/Index.aspx/HelloWorld"

Kiran Sonawane

this url: "~/Index.aspx/HelloWorld"

could be

url: "Index.aspx/HelloWorld",

I guess tilde(~) sign is not recognized by JS compiler

still not working.....

Show your output from

http://your_domain_name.com/Index.aspx/HellowWorld

OR if it is in development server

then

http://localhost:yourport/Index.aspx/HellowWorld

StingRaY

Try this

<WebMethod(EnableSession:=False)> _
    Public Shared Function HelloWorld() As String
        Return "{Hello: " & DateTime.Now.Millisecond & "}"
    End Function

Still no joy.

I have stripped my code down to about two files and attached a zip file.

I have renamed the ext txt....

Hopefully this will allow you to have a play rather than guessing?

If you need any more info let me know?

what do you get from the net tab in firebug?

StingRaY

What if you get the page with this code

$.ajax({
        type: "POST",
        url: "~/Index.aspx/HelloWorld",
        data: "{}",
        contentType: "text/html",
        dataType: "html",
        success: function (msg) {
            // Replace the div's content with the page method's return.
            alert(msg);
        }
    });

Open in new window

StingRaY

Or try this

$.ajax({
        type: "POST",
        url: "Index.aspx/HelloWorld",
        data: "{}",
        contentType: "text/html",
        dataType: "html",
        success: function (msg) {
            // Replace the div's content with the page method's return.
            alert(msg);
        }
    });

Open in new window

stringray your last post gave me a load of html back but I couldnt debug into the function in .net?

Is it worth you having a go of the project I gave?

StingRaY

Since I'm not much familiar to .NET, I'm not if you have to set the returned content type as "text/javascript" or "application/json".

See this link for further detail.

StingRaY

Yes, my last post queries for a html page instead of json page. This is my intention to check if your page returns what you expect. You have said it returns html code instead of json like {Hello:155351123}. This means there is something wrong with your page.

Check what you have received in your full website. You can use network tab in the firebug or Network tab in google chrome's developer tools to inspect these.

I'm stuck on a council network at the moment that is blocking me from downloading firebug or chrome.....

Will have to have a look once i've managed to get access....

You are using IE? which version? if 9, there is the similar feature in Network tab in Developer Tools in IE9.
