Loading client-side images for use in Javascript

[j0vo]

Ok, I'll play the dumb guy.... if your script is running on the server under
the testapp application, why isn't the source 'Images/down.gif' (Path
relative) to the application and the full path on the server? At least if
nothing else, this would make the code more transportable to serveral hosts
without having to rely on the fact that inetpub/wwwroot is the actual root
of the web server (which it is not on my machines).

Cheers

Hi,

I did actually try "..\Images\down.gif" and "Images/down.gif" and both don't
work for me. WHat now?

Regards
John.

Hi

var imgDown = new Image();
imgDown.src = "PATH/Image.gif";

setNewImg(e){
e.src = imgDown.src;
}

<img onclick="setNewImg(this)">

Hi Vidar,

Please excuse the ignorance but what should I use in the 'PATH' part? The
stringbuilder section where I write the javascript text is from within a
user control which is in another folder off the web root.

Regards
John.

I did not see your prior posts, but if the script is on the executing on
the web server in the context of the app, then things should be cool with
path absolute or relative. But your subject line indicates that perhaps the
script is a client-side script running in the browser. If it is a script
running in the browser, then I would not ever expect path relative or
absolute addressing from the client script to ever be able to directly
access a file on the web server like you have it.

Instead, I would imagine the .NET aspx to script something like

string newPath = Request.Application.Path + "/images/down.gif";

where the above body is specified in a runat=server block of code -- so that
the application path can be rewritten by the web server so that the client
browser can load it via URL.


That is my guess, not knowing anything about your application -- Hope it
helps, good luck
