Hi,

When I use YoYo_GetDomain while testing the game by opening index.html in my browser, it *returns* "undefined".
(Well, when drawing YoYo_GetDomain, it draws "undefined")

So how can I detect if a string is undefined?

if (YoYo_GetDomain == "undefined") // won't work!

it is a function so it needs parenthesis

undefined is a JavaScript value, GML doesn't know anything about it. If you really need to detect it you could use a JavaScript extension, but you probably can just ignore it.

Here is your answer:

If you would have tested it under Windows first as opposed to HTML5, you would have received an error straight away because you're trying to display a variable that doesn't exist. And that's because YoYo_GetDomain() isn't a variable.

YoYo_GetDomain() gives me an error, so what am I supposed to do?

This gives you an error?

show_message(YoYo_GetDomain());

show_message(YoYo_GetDomain());

Yep, it won't even let me compile...

Show us the script that doesn't compile, and show us the error message you're getting.

Does it Syntax Highlight, YoYo_GetDomain()?

What version of GameMaker:HTML5 Are you using?

undefined is a JavaScript value, GML doesn't know anything about it. If you really need to detect it you could use a JavaScript extension, but you probably can just ignore it.

I don't think it's possible with a Javascript extension. I believe variables checks are done before passing variables to a Javascript extension function.

Syntax Highlighting doesn't work either.

Not sure about the version, not at home so can't see which version it is.

I guess I'll try it with an extension

[Schalk]

Then you're using an old version.

Open GameMaker:HTML5
Click on the "Help" menu.
Then click "Release Notes". A webpage should now popup.
Then click on the orange link at the top with, "Version 1.0.187".
And install

YoYo_GetDomain() was added in version 1.0.170 --- just in case you needed to know.
