Call A Web Service In Javascript?

Nov 5, 2010

As the title states, I'm trying to call a web service written in ASP.Net (Same solution, but different project in visual studio) from javascript. Since I added the web reference for the service prior to this for calling it in VB.Net, I tried to use this reference by directly calling it.In the body of the Default.aspx page, I have this code:

<asp:ScriptManager id="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="~/App_WebReferences/localhost/ServiceName.discomap" InlineScript="true" />
</Services>
</asp:ScriptManager>

but in javascript, I can't call my service at all. Could anyone explain me how? I'd want to do something like this:

<script type="text/javascript">
alert(ServiceName.HelloWorld())
</script>

Call WCF Service Through Javascript - AJAX Or JQuery

Jan 13, 2011

I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is [URL]). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Some of the changes I made was adding the following to the Operation Contract:

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "SetFoo")]
void SetFoo(string Id);

Then this above the implementation of the interface:

[AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]

Then in the service webconfig I have this (parens are angle brackets):

<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
<add prefix=[URL]>>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />

Then in the client side I attempted this:

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
<compositeScript>
<Scripts>
<asp:ScriptReference
Path=[URL]/>
</Scripts>
</CompositeScript>
</asp:ScriptManagerProxy>

I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc.... I am willing to make any changes.

Javascript Refuses To Call ActiveX Method - Agrees To Call Another

Mar 4, 2010

I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.

Talking To A Rest Service / Call A Rest Service Without Having To Redirect?

Feb 8, 2010

I need to call a Rest service but would like to do so without having to redirect. Here is my dilemma. The Rest service we are trying to integrate offers the option to sign up for a subscription but does not allow us to upgrade an existing subscription. So if a user wants to upgrade an existing subscription we have to first cancel and then have the user sign up for a brand new subscription. I don't know how I can make this so it flows nicely in my code. I ideally I would like to do something like this

User decides to upgrade

Click upgrade button

Existing account is being cancelled, if cancellation was successful

New account is being created

How can I do this with a Rest service? Here is a sample URI/URL

https://someservice.com?
Action=CancelSubscriptionAndRefund
&AWSAccessKeyId=AKIAIIFXJCFIHITREP4Q
&CallerReference=CallerReference07
&CancelReason=MyWish
&RefundAmount.CurrencyCode=USD
&RefundAmount.Value=1
&SignatureMethod=HmacSHA256
&SignatureVersion=2
&Signature=1uFUSSFvau1zadnSzKRS5ZchuLMn9p5M3ifaHGHie7M%3D
&SubscriptionId=17d62772-c53e-4bdb-9667-65d7b7841cfc
&Timestamp=2009-10-06T08%3A05%3A13.296Z
&Version=2008-09-

Could anybody give me some ideas how to make this work in an elegant manner. We thought we could keep the old subscription and then just sign the user up for a new subscription for the difference of the money. For example the first subscription would be 2.95 and the second one would be 2.00 which would amount to a subscription of 4.95. I think it is not elegant and the user would see 2 charges on the credit card, weird, I think. Since I don't know much about Rest maybe there is a way that this can be solved.

How To Asynchronously Call A Web Service

Aug 27, 2010

I need to asychronously call a web service from an ASP.NET application. The aspx does not need the answer from the web service. It's just a simple notification.

I'm using the ...Async() method from web service stub and <%@Page Async="True" %>.

ws.HelloWorldAsync();

My problem: the web page request is waiting for the web service response.

How to solve this problem? How to avoid any resource leak when the web service is down or when there is an overload?

How To Call To The Database Via Ria Service

Oct 18, 2010

I was wondering why you would still use ASP over Silverlight, since with silverlight there is a lot you can do already. And you dont have to use css, jquery, js, html, etc.

Also with silverlight you can do a call to the database via ria service.

I can only think of 1 reason which is, that not every one has the plugin installed. But thats just a matter of time.

WCF / ASMX :: What Happens After A Web Service Call

The result returned is correct when I checked at debug mode.

However the actual result taken from fiddler is "This is );jsonp1286206213419( a test"

Why is a ");jsonp1286206213419(" inserted into the result? How do I troubleshoot this?

C# - Can't Call A Web-service Twice In One Page

May 11, 2010

I built a web-application which calls a web-service twice in the application's log-in page - first, on Page_Load, and the second time is after a button click. When debugging, everything goes well, but after publishing the web-application and trying it - I cannot make the two calls for the web-service (each call is invoking a different function in the same web-service).

If I call it once (say, in the Page_Load) its OK, but once I get to the button click event, the page just seems to be loading but actually doing nothing (loading to infinity).

When I disabled the web-service call in Page_Load, the web-service call after the button click worked well, and if I switched between them (disabled the call in button click and enabled the call in Page_Load) the enabled one worked OK.

How come this is happening? What did I do wrong? Could it be related to the fact that the location where I published my web-application has some URL-rewriting rules?

AJAX :: Trying To Get AutoComplete To Call Web Service

Apr 26, 2010

I'm going on my 3rd day trying to get my Ajax AutoComplete textbox to call my web method. Based on my google searches, I'm not alone. I suspect the problem has something to do with the ServicePath property on the extender, although I'm not sure. My web service is at the same level, on the same server as my test web page. I'm not sure exactly what should go into the ServicePath property, although I think I've tried every possibility. Below is my web service followed by my script.

C# - How To Cancel A Web Service Call If It's Not Responding

Apr 8, 2010

I have a web page (.aspx) that calls a third party web service to get some data. It usually takes couple of seconds to get the response back, and then the rest of the page will load. Occasionally the call gets stuck either due to the web service is down, or internet connection, etc., the page just hang there and will not load.

My questions is:

1) Is there a way to abort/cancel the web service call after a set amount of time?

2) Is it even possible to verify the status of the web service before calling it?

Call Web Service From Another Web Application Using Jquery?

My jquery call looks like this:

[code]....

Note that [URL] works in the browser but since the jquery call is from localhost:3410 i assume its a problem with cross domain.

I have been reading that i should use jsonp for this, but i have a hard time figuring it out.

Call A WCF Service Outside Of The Impersonation Context?

Jul 30, 2010

I'm having problems with impersonation in WCF. Namely, I'm calling a named pipe service from within ASP.NET with impersonation turned on. This fails (due to permissions on the pipe blocking anyone from the network). So, is there any way I can make the call outside of the impersonation context? I don't need to be impersonating to make this call, but can't see any way of doing this.

PS. I need to do this declaratively, through config...

WCF / ASMX :: Is It Possible To Intercept Web Service Call

Feb 28, 2011

n my A.aspx, I will call web method GetName in B.asmx

Is it possible, before my A.aspx call GetName in B.asmx, I inject or put some codes so when A.aspx try to call the method, it needs to go through my injected code without even changing the code in A.aspx and B.asmx?

Is custom HttpModule able to handle this scenario? If yes, how? Which HttpModule's event that occurred before the page actually called the web service?
