Javascript void no longer works with VS Code error "unable to open void(0)"

[marckruzik]

Describe the bug

Javascript code often uses "void(0)" to have a blank link, with no special behaviour from the browser, usually with an associated onClick event. I just updated Polyglot Notebook (EDIT: and VS Code), and now all my "void(0)" link are producing errors.

Here is how to reproduce the bug. In a html cell, write the following:

<a href="javascript:void(0);" onClick="alert('hello')">Click on me</a>

Click on the link.

Visual Studio displays an error:

Is that a bug? Or is "void(0)" a bad practice which should no longer be used? If so, how to get the intended behavior?

Please complete the following:

Which version of .NET Interactive are you using? (In a notebook, run the #!about magic command. ):

[jonsequitur]

The behavior change is in VS Code and is outside the scope of the Polyglot Notebooks extension.

As a workaround (at least for my own scripts), I can replace the links by buttons. Before:

<a href="javascript:void(0);" onClick="MyFunction();">text</a>

After:

<button onClick="MyFunction();">text</button>

The behavior change is in VS Code and is outside the scope of the Polyglot Notebooks extension.

Ok. I am closing the issue for now. We will see if the problem arises in some extension.
