Hi Doug,

It helps but it is not what I want.

I want to access a object stored in the global js namespace of the browser.
For instance, this is available in your js console on the browser when you
work with IPython/Jupyter:
*IPython.notebook.notebook_name*

But if I do:

*%%javascriptIPython.notebook.kernel.execute("python_var = " +
IPython.notebook.notebook_name);*

It doesn't work.

In your example, where is *javascript_var* stored?
