I have a page named MyPage.htm which contains the html below.
I'm trying to access a Web Service using only the Microsoft AJAX Library.
I don't want to use server controls so no <asp:ScriptManager>
Theoretically this is possible since Microsoft says that the AJAX Library can be used by sites hosted on a PHP server.
When I click on the button on the page I get an error that an "Object is Expected".
Anybody know what I have to do to get the Web Page to work?
<
html><head>
<title>Untitled Page</title>
</head>
<body>
<formid="form1">
<scriptsrc="bin/MicrosoftAjax.js"type="text/javascript"/>
<scriptsrc="bin/MicrosoftAjaxWebForms.js"type="text/javascript"/>
<scriptsrc="bin/MicrosoftAjaxTimer.js"type="text/javascript"/>
<scriptsrc="MyService.asmx/jsdebug"type="text/javascript"/>
<scripttype="text/javascript">
Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);
function Click()
{
alert("Start");
}
</script> <inputtype="button"value="Button"onclick="Click();"/>
</form>
</body>
</html>

Hi John,
you are trying to initialize a scriptmanager control that isn't there. thats the reason why you get the error "object expected"
Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1'));
take a look at this link:
http://www.c-sharpcorner.com/UploadFile/deepakvraghavan/AjaxProgressBars09082006171908PM/AjaxProgressBars.aspx
succes
Regards,
Even after I remove the two "Sys.WebForms" lines of code I get the "Object Expected" error.
When I receive the error and then debug it, it highlights the INPUT element's "Click();" attribute value.
Thanx,
John Grieb
Hi John,
I copied your code and i get the same errror as you. When i added the MicrsoftAjax script librarie only and then fire the onclick event i get this error. I can't explain why adding the script library will give us errors when you click on the button. hopefully someone else can!! I'am very curious.
Kind regards,
type <script type="text/javascript" ></script> instead of <script type="text/javascript />
I hope it helps.
Hi Fatbeaver,
It worked for me! So i hope it will also work for John.
Thanks,
Worked great.
Thank you very much.
I appreciate your help.

Dear All,
I'm a newbie and really interested in AJAX.
I write that codes above, based on your article.
But, I get problem when accessing the webservice's methods. It doesn't recognize the "Sample.Aspnet"
In myhttp://localhost/WebService1/Service.asmx I put simple WebMethod Test().
here is my webservice code:
Namespace
Sample.AspnetNamespace:="http://indsuw0577/WebService1/")> _PublicClass OracleDataAccessInherits System.Web.Services.WebService<System.Web.Services.WebService(
PublicFunction Test()AsStringReturn "testing webservice"EndFunction<WebMethod(Description:="test new simple webservice")> _
End
ClassEnd
Namespacecan anyone please explain me how to correctly write a webservice reference and the way to call its methods?
Really appreciate your help.
Regards,
Joko P
One thing I noticed that you need to do is add the <ScriptService> attribute to your Web Service class and the <ScriptMethod> attribute to you Web Service Method.

Thanks a lot.
Have you ever accessed a webservice from another domain/sub domain?
The sample always teach us to access the local web service. I've not found the sample for cross-domain yet.
Please help
Thanks n Best Regards,

The AJAX CTP has a feature called Bridge files.
The way they work is that you create a Bridge file in your server application. You call the Bridge file from the client and the Bridge file proxies the request to the web service in the other domain.

May I know if there are any samples regarding the bridge files?
