Problems with ON when creating tags that disappear when the DOJO button is pressed

Asked 1 years ago, Updated 1 years ago, 348 views

The goal is to make these codes work.At this stage, there is no problem if you allow certain tags to disappear.

If possible, we would like to add additional registration function to the button that disappears the tag.

★For convenience, we created bundle.js in the link below, and we have deleted the description as the problem has become more multifaceted this time.
Also, bundle.js alone works.

If there is any solution, please take care of it.

on(registry.byId("button1"), "click", myClick);
parser.parse();

Note that parser.parse() in dojo/parser creates a Widget with data-dojo-type.The previous line has not yet run parser.parse(), so the button1Widget has not been created, and of course it cannot be retrieved in registry.byId().

parser.parse().then(function(){
    on(registry.byId("button1"), "click", myClick);
});

How about waiting for and parser.parse() to complete?

I missed one more point.

<script src="https://ajax.googleapis.com/ajax/libs/dojo/1.13.0/dojo/dojo.js" data-dojo-config="isDebug:1, async:1, parseOnLoad:1"></script>

dojo/parser, but

    Implicitly initiated by specifying
  • data-dojo-config="parseOnLoad:1".
  • explicitly initiated by
  • parser.parse().

I don't know the exact behavior, but the two executions seem to be competing.As mentioned earlier, I would like to run on() after completing parser.parse(), so how about setting it to parseOnLoad:false and parser.parse() only?
