See original GitHub issue

Due to jQuery not being defined in jupyterlab, the %%cython magic is unable to show interactive html when invoked inside jupyterlab. See also jupyterlab#2634.

Ok, think I figured this out. The following works in a jupyterlab notebook:


from IPython.core.magic import Magics, magics_class, line_magic
from IPython.display import display, HTML
toggleDiv = """
this.nextElementSibling.style.display != 'block' ? 
this.nextElementSibling.style.display = 'block' : 
this.nextElementSibling.style.display = 'none'
"""

HTML(f"""
    <button onClick="{toggleDiv}">Click</button>
    <div style='display=none'>ok</div>""")

The workaround is inlining the toggleDiv in the html, and not using the scripttag. Come to think of it, isn’t this just as much of a security issue as allowing js scripts?

I’d be happy to see a pull request by someone who understands (a bit) how jupyterlab wants these things to work. The code isn’t complex, it’s not using jQuery, and it’s right here:
