this.$textarea.on(...).on(...).on is not a function

[simplenotezy]

I am getting the following error:

this.$textarea.on(...).on(...).on is not a function

It used to work fine 10 minutes ago. I did not make any changes to this.

Can you provide a jsfiddle with a working example of the error?

Same here!

Issue caused by jquery/jquery#2812, fixed should be pushed to 1.12.1/2.2.1 other jquery version will work!

Note, though, that passing an undefined handler is not supported and never has. We plan to fix it for 2.2.1 because it's inconsistent with how 1.12.0 works and we want both versions to be as close to each other as possible. This will most likely just start throwing in jQuery 3.0.0 (we'll have a beta out soon). If you disagree with this, please comment on #2812.

@mgol Can you explain a bit more what is wrong with this piece of code? I don't understand what you mean!

[mgol]

@acrobat elem.on(eventName, null or undefined) is not and has never been supported. See https://api.jquery.com/on/, there is no such signature in the docs.

[mgol]

And I assume this piece of code doesn't work because this.keypress is undefined and so is $.proxy(this.keypress, this).

How do we overcome this issue? Bootstrap 4 alpha depends on jQuery 1.9.1 - 2

@mgol thanks for the info! I will push a fix to this library!

bootstrap-markdown 2.10.0 was released with a fix for this issue!
