Your code worked on chrome for me.
In addition
Your ThreePage.dyalog code was very instructive. It showed me the syntax
for:
1) how to use type=importmap with _.script ScriptFollows
2) how to use type=module with _.script
It also showed
3) how to capture info in a Page's or Template's public field
4) how to construct a script on the fly and add it to the Head
I noticed that:
When referencing a template in a page, I believe
that if I use #.ThreePage DUI looks in ServerRoot/Core
and if I use just ThreePage, DUI looks in SiteRoot/Code/Templates

Re: javascript es6 modules
Bryant,
it's good news to see that this example served its purpose.
WRT loading, your assumptions are partially correct. Let's look in more detail at the process:
Also, if you end up writing tools that you need to use on > 1 .mipage, you don't have to duplicate that code in every page, just put it into the /app/Code folder. You can use .dyalog files that contain namespaces, classes or even simple fns.
I hope this helps for the next steps...

WRT loading, your assumptions are partially correct. Let's look in more detail at the process:
- at startup, DUI loads code from disc into the workspace. Some bits that are relevant for us:
- /DUI/Core goes into #
- /app/Code goes into #
- /app/Code/Templates goes into
#.Pages
- when the browser asks for a file: DUI checks if that file is a .mipage. If it is and if it is found in #.Pages (and has the file has the same timestamp as it had when we loaded it last time), that instance is called. If it does not exist, has a newer timestamp or a different extension, DUI searches the app folder. (BTW, you can also have a folder structure on disc that the URLs need to mirror, i.e. /a/b/c/foo.mipage asks for /app/a/b/c/foo.mipage).
- when such a .mipage is instantiated, the interpreter requires that its base class exists - otherwise it throws an error. The base class will exist if it exists in /app/Code/Templates (and thus was loaded at startup). If you refer to a class in #, it may have been loaded at startup from several possible locations - but it is recommended practice to keep the templates in their folder.
Also, if you end up writing tools that you need to use on > 1 .mipage, you don't have to duplicate that code in every page, just put it into the /app/Code folder. You can use .dyalog files that contain namespaces, classes or even simple fns.
I hope this helps for the next steps...

Re: javascript es6 modules
Hi Michael
I am having another basic problem with DUI/MiServer.
I build a page with buttons; in a callback I clone
the selected button; then I try to append the cloned
button to an existing div. The cloned button appears
for a brief second and then disappears. I assume that
MiServer/DUI is reloading the entire page. I used APLJax
in the code and it still happens. What am I missing
about how pages are refreshed?
Thanks in advance

Re: javascript es6 modules
Hi Bryant,
usually a callback does not trigger a reload of the page, so something must be going wrong somewhere - but it's impossible to say w/o seeing the code.
Feel free to email me {ForumHandle}@dyalog.com) - it would be great if you could zip the whole MiSite...
(Confidentiality will be kept, but we can discuss formal NDA as well, if neccessary)
Thanka

Hi Bryant,
I thought I should add that when Michael gives his email address as forum handle that that is his name without the "|Dyalog" part of the forum handle text.
Regards,
Vince

Re: javascript es6 modules
Thanks Vince. That as my first guess, but when I tried it, it bounced.
Michael has since sent me email so I have his address.
