html - IPython: Adding Javascript scripts to IPython notebook

Question

As a part of a project, I need to embedd some javascripts inside an IPython module. This is what I want to do:

from IPython.display import display,Javascript
Javascript('echo("sdfds");',lib='/home/student/Gl.js')

My Gl.js looks like this

function echo(a){
alert(a);
}

Is there some way so that I can embed "Gl.js" and other such external scripts inside the notebook, such that I dont have to include them as 'lib' argument everytime I try to execute some Javascript code which requires to that library.

As a very short-term solution, you can make use of the IPython display() and HTML() functions to inject some JavaScript into the page.

from IPython.display import display, HTML
js = "<script>alert('Hello World!');</script>"
display(HTML(js))

Although I do not recommend this over the official custom.js method, I do sometimes find it useful to quickly test something or to dynamically generate a small JavaScript snippet.
