JavaScript

Hi,

I am new to jQuery, ajax and signalR.

I have this code in Popup.js file, I don't know what it is and I don't know how it executes, but I can understand that this code is to open popups one with close button and another without close button, because I commented and ran it, but I want to have the control over setting which popup to have close and which not. I am trying my best and placing the code in the aspx and ascx files.
I am not understanding, can some one please help me with this, and if I want to overwrite this same functionality in the local popup, page or user control how can I do that?

Any help code snippet, link or even suggestion would be greatly helpful

var control ={
---
convertLinkToPopupWithClose: function (event, informParentOnClose) {
    return ELMS.WebControls.Popup.convertLinkToPopup(event, { showClose: true, closeInformsParent: informParentOnClose | false });
},
convertLinkToPopupWithoutClose: function (event, informParentOnClose) {
    return ELMS.WebControls.Popup.convertLinkToPopup(event, { showClose: false, closeInformsParent: informParentOnClose | false });
},
----
}

Thanks & Regards,

If you know which block of code it is complaining about then please edit your question, remove all the other stuff, and then format what's left for easier reading.

What is an AXD file

Hi All,

I am maintaining an application in which in client side script it is adding a button as below in which it showing some axd file, can some one explain me how can I go to this button click event?
When I went to the xxxxx/Prescreen folder location I don't find any file named Image.axd, what can I do to handle this situation.

Can anybody please help me in finding what exactly it means? any link, any suggestion or code snippet would be very helpful, all I want is to go and see what it doing when we click the "btnAdditionalFamilyQuestions" button.

<input type="button" name="btnAdditionalFamilyQuestions" id="btnAdditionalFamilyQuestions" value="Additional Family Questions" style="width: 215px; 
background-image: url(http://localhost/xxx/xxxxx/Prescreen/Image.axd?r=0&g=178&b=214&p=20&h=25&t=Additional%20Family%20Questions);">

Thanks in advance.

Is Google not working where you are? The first result of searching of "axd": What is an .axd file? [Stack Overflow][^]

An .axd file isn't a physical file on disk; it's an IHttpHandler (or IHttpHandlerFactory) registered in the web.config file.

Sorry, may be I was little quick to ask but I have been googling, but one thing I am not able to understand that how can I debug a file or code that's using axd extension, very unfortunate thing is as I have been writing lot of server side code for a while I am used to debug the code.

Can you please help me in that aspect, just in the below button click event it is opening a popup, how can I understand or debug what is it trying to do in that button click, what I understood is all that information can be obtained by that .axd file, but I am not sure how to crack it, please help me, if I wrongly understood please correct me.

<input type="button" name="btnAdditionalFamilyQuestions" id="btnAdditionalFamilyQuestions" value="Additional Family Questions" style="width: 215px; 
background-image: url(http://localhost/xxx/xxxxx/Prescreen/Image.axd?r=0&g=178&b=214&p=20&h=25&t=Additional%20Family%20Questions);">

Thank you.

If you look in your web.config file - either under system.webServer/handlers or system.web/httpHandlers, depending on whether your site is using the Integrated or Classic pipeline - you will see an <add ...> element with the path set to "image.axd".

The type attribute on that element will tell you which class handles the image.axd requests.

Assuming you have the source code for that class, you should then be able to set a breakpoint within the ProcessRequest method and debug it.

Re: Calling an ASMX Web Service through JQuery .Ajax

The following is my HTML page. My problem is with invokeService(). It correctly determines the body and places it in data - but then it never sends the data. Fiddler shows no JSON data was sent. The Success routine is called but the data is null (as would be expected with no input data).

Can anyone tell me what I am missing or did wrong. How do I send the JSON to the service?

Thanks Brent

If it hits the success function that tells me it called your service correctly. Did you put a breakpoint in your webmethod?

The service is not mine, unfortunately, but, like I said, Fiddler confirms that no data was sent. Is there something I need to do to prepare the data to be sent?

What is the signature for your GetFVRSVoter() method?

Re: Calling an ASMX Web Service through JQuery .Ajax

3-Feb-15 2:57

I'm wondering if I'm wasting my time here.

History: Our vendor created this service and also gave us a web site where everything works, but he never gave us access to the WSDL. My employer wanted it to do something different, so asked me to extract the functionality and use it in our own web site. So I don't even have a signature, I am just copying out what is in the vendor's JavaScript file. Is doing something like that even possible? Or am I running in to cross-site scripting problems? This could be something entirely different.

But when I run the same script in the vendor's web page, Fiddler shows the data being sent and so when mine gets called and no data is sent, I am just hoping it is me doing something wrong instead of me trying to do something impossible.

Thanks

Brent

Thanks for the additional info. It is possible you are having cross-site issues; however, I believe the error function is called when that happens.

It may be a proxy authentication problem. I managed to get it working in c#, but had to use proxy authentication.

How would I do proxy authentication for this in javascript?
