compilation doesn't work

[zohaad]

it gives errors while running after I compile it with chrome

Uncaught TypeError: node.classList.indexOf is not a function
I changed node.classList.indexOf > -1 to node.classList.contains('ace_editor') (this fixed the error)

Uncaught TypeError: Cannot read property 'toLowerCase' of undefined

I don't know how to fix the last error

I fixed by replacing lines 10-13 with:

if (node.nodeName.toLowerCase() == 'input' || node.nodeName.toLowerCase() == 'textarea' || (node.classList && node.classList.contains('ace_editor'))) { return; }

Added an undefined check to the classList for some cases.
