<img src="United-Kingdom-Flag.png" style="width:px;height:px" onclick="alert('changing to English')">

Re: Calling xbasic from image event

sure, do an ajax callback (let the action js builder generate the code for you) What exactly is it you want to do ?

Re: Calling xbasic from image event

Hi Frank,

I am having a Tabbed UI builder where I have placed two images in the footer section one with a Danish flag and one with an English flag and when the user is pressing the flag I want the JavaScript to call an xbasic function to change the active language, if i use the action builder i am getting this suggestion

{grid.Object}.ajaxCallback(part,rowNum,xbasicFunction [,callbackURL [,additionalData]]);

and I don't really know JavaScript, but in the help it is saying that the part should be 'G', 'S', 'D' for search grid or detail, but I am using the footer of the tabbed UI so what should i Use, i am including the definitions I have done in the builder

Re: Calling xbasic from image event

I'm not completely sure about this but I'm wondering is the standard method of using an Ajax Callback is not available in a Tabbed UI.

If it is then... nevermind.

However... here's another way of getting this done easily.

http://www.youtube.com/watch?v=ZGpacC0pKiQ

Here's the Header text I'm using...

<h1>Reservations</h1> Current language is : <span id="currLang"></span>

I've got a span tag in there to show the language I've selected.

Here's the Footer text I'm using...

Select your language by clicking the flag <img src="denmark.png" style="width:px; height:px; cursor:pointer;" onclick="setCurrLang('DK');">  <img src="canada.png" style="width:px; height:px;cursor:pointer;" onclick="setCurrLang('CA');">

I'm using one javascript function with the language set as a parameter.

The javascript function is...

function setCurrLang(lang){


$('currLang').innerHTML = lang;

A5.ajax.callback('setCurrLang.ajax.a5w','currLang=' + lang + '');


}

This function puts the selected language into the header and then does an A5.ajax.callback to an a5w page. The a5w page sets the session variables.

This is the code in the setCurrLang.ajax.a5w page

<%a5

	dim currLang as c = default "no language set"
	session.__protected__activelanguage = currLang
	session.mylanguage = session.__protected__activelanguage

%>

So... now there's an indication on the tabbed ui of which language is selected and the session vars are set.

Thanks David, that is exactly what I wanted, and I think you are right that a normal Ajax callback wont Work in the Tabbed UI.

Re: Calling xbasic from image event

Well there's no action js to create ajax callbacks in a tabbed ui but you can do it. See this article: http://wiki.alphasoftware.com/~alpha...+in+Alpha+Five

David,
Could you please show code placed in the function OnTitlesRender mentioned in the video, I have tried to check debug and see what "e" contains and can't see the value that was set in the a5w page.

There is also mention of below in the functions comments not sure if they apply.

'Session - The Session object. Should be used instead of the older e.session construct
' - To set a session variable: Session.myNewSessionVariable = "Alpha"

Re: Calling xbasic from image event

Kotin,

Because the a5w page is setting a session variable... e.g.

session.__protected__activelanguage = currLang

Then that session variable is available from any of the server-side events of the grid I was calling.
Depending on what you want to do, that session variable can also be made available to javascript through "publishing session variables".

Specifically, in the onTitlesRender Server-side event, I only need to reference that session variable.

Dim mylang as c = session.__protected__activelanguage

Is this what you wanted?

Re: Calling xbasic from image event

I think I have messed up something in this test project.
Created the a5w file, created the code as shown, published all files but now getting this double error, when try and run.

exists a5w file but error shown when running app.jpg

live preview error, despite uploading all files

Re: Calling xbasic from image event

It looks like your session variable cannot be found in onTitlesRender because the A5W page that is establishing that session variable cannot be found and therefore is not run. You have to make sure your a5w page is available (published) to livepreview as well. Open it and run it in live preview... even though it might generate errors... at least it will be published to LivePreview.

Re: Calling xbasic from image event

David,
Thanks for checking.
I think it is "user" error on my part but for the now can't still understand what I have done wrong.
Have gone through publishing each item on its own, first time round din't work. went back to the a5w file, open for edit, selected wsywig tab, it filled in html stuff around the a5w code, published, this time worked but did generate an error (assume this is fine).
Will retrace my steps to nail the publish requirements.

Re: Calling xbasic from image event

Hey Kotin,

I don't know what you're developing... for whom, etc... but... noticing your signature area... if you're not locked into Build 1856 for any reason I'd move on to the pre-release builds. There's some amazing stuff in there. Go to Help, View Release Notes to get a link to the pre-release builds.

I'd also move off Vista. At least make the move to Windows 7... if not Windows 8. I can't say 8.1 because I didn't make that move... seems too dangerous. But 7 or 8 is excellent.

Re: Calling xbasic from image event

Will eventually upgrade but cautious in that I am more familiar in Vista Professional.
On the license, I am doubly cautious since I know that you only allowed to install two instances of the application. I already have one on yet another vista box and reading on the process of activation, I need to know for sure that I can "transfer" my install to any other machine, provided Alpha company can provide me a mechanism of declaringt o them that I need to "demote" an installation to be a trial version and move the license to another machine all together.
On the version I am running, I purchased the proficiency package that was for developer, server and runtime. Believe has a 1 year license in that I should be able to upgrade all releases with the said year.
When I go to check version, the app tells me that I am upto date, been meaning to ask how I upgrade the indeterminate releases...

Re: Calling xbasic from image event

Check version will always compare against the Official Release. For the pre-releases... Help, View Release Notes, click the link under The 'Pre-Release' Build. Select the install you want (I ususally do full_patch and appserver_patch). Make sure you install into wherever you have V12 installed. Help, About will then show you the current pre-release you have installed. It is 'pre-release' though... so... take that into consideration.

Re: Calling xbasic from image event

Thanks, Had seen new videos in the blog section of alphasoftware and wondered when I would get hold of that release. Thanks for pointing me to this, hope other will also find this useful.
