I'm seeing some strange behavior using Javascript cells in a (trusted) Jupyter notebook.
For example, I can execute the following cells, intended to fetch the current URL of the notebook.
%%javascript
var kernel = IPython.notebook.kernel;
var thename = window.location.href;
var command = "notebook_url = " + "'"+thename+"'";
kernel.execute(command);
And now I try to access the variable in another cell:
print notebook_url
This works as expected with I run the cells one after another (Shift + Enter), but throws a NameError: name 'notebook_url' is not defined when I try to 'Run All' cells.
How could I get this to work with 'Run All'?
