Javascript does not work at colaboratory

Question

Pop-ups are output at datalab but not at the colaboratory.

test = """
<script type="text/Javascript">
alert("hi")
</script>
"""
from IPython.display import HTML
HTML(test)

Is it a colaboratory bug? How can I pop up normally?
thanks

I don't think it's a bug. Each output is rendered in an iframe sandbox, and the sandbox doesn't have the popup capability.

A simple work-around is to use something like raw_input to prompt the user, e.g.,

value = raw_input('Enter value: ')
print 'entered', value

I do not know what you mean. colaboratory and dataLab appear to be the same engine. But why does not it work only on a colaboratory?

Do you have a better UI design than just raw_input? For example, I want to do some interaction like multiple choices a few times. Then use those choices to calculate something.

@KorakotChaovavanich The purpose of the MNIST example is to use a layout in JavaScript.
