Please create new cell above and use:

 load("./path/to/local/javascript_ifle.js")

Best regards, Andrey.

If you write markdown or html code it will be hidden automatically. If you don't want this please use:

%md(hide = False)
%html(hide = False)

If doubleclick doesn't work please select cell output and press the </> button.

Best regards, Andrey.

If you are about .sagews files, you need press ctrl and / buttons. This will work only when your keyboard layout is English.

Best regards, Andrey.

I try to use function sage_eval and It seems for me that either I found bug either I don't understand smth.

cmds = """
def somef():
    return 443
res = somef()"""
sage_eval('res', cmds = cmds)

NameError: global name '_sage_const_443' is not defined

sage_eval('res', cmds="def somef(): return 443; res=somef()")
