Hi Filipe,

Maybe you're using the wrong Id. Try filling in the "name" property of you hidden input (with MyInput, for example) and to generate your javascript use the runtime property MyInput.Id.

Attached I placed a very simple sample eSpace that does that (you need Service Studio 4.1 to open it)

Hi Filipe.

Check Out this topic, to see if it helps.

Then you could just add a screen preparation and fill some local variable, and then set an expression to it...

Hi Filipe,

If you want to use a value on a Web Screen that must be processed on the server (like getting the host name), the way to do it is like Diogo said:
1 - Add a screen preparation action to your Web Screen;
2 - In that screen preparation action, place the Outsystems flow that fills in a local variable with the value you want (and for that you'll maybe want to use the extension that is available on the post referenced by Diogo);
3 - Use that local variable in your Web Screen as needed.

If you want to execute a piece of javascript when your Web Screen loads on the client's Web Browser, simply place an "onload" extended property in your Web Screen with the javascript to execute. Attached I placed my sample eSpace that now uses the onload extended property to place the value "Value Placed OnLoad Event" on the "FirstInput" once the page is loaded (see the screen extended properties).

The fact is that I still did not clearly understand what you are trying to do.

Hi Filipe.

Seems to me that you're making it too complicate. Why don't you fill the variable's value in the preparation action? You can do this using the built-in function GetOwnerURLPath() and parsing the value. This function returns the URL path of the eSpace that owns the element that is being processed so it should be something like https://hostname/espace.

Hope this helps. Cheers,

Hi Filipe,

If you want to show the name of the client machine you'll need to inspect the HTTP Request object. I think that you don't have this available in the HTTPRequestHandler extension so you'll need to code the extension yourself.
You can use the GetRequestContent() but this will return the full request as a string and you'll need to parse it.
Probably the best would be to code an extension to return the client hostname using:
HttpContext.Current.Request.UserHostName

Hope this helps. Cheers,
André
