Uncaught TypeError: Cannot read property 'className' of undefined

Question

The following error is being thrown in Google Chrome\'s developers tools:

Uncaught TypeError: Cannot read property \'className\' of undefined

Answer 1

Encountered similar problem. Root case was that while dataTable was about to take control of the table, our code also tried to manipulate properties of the table a the same time. The error message does not say so, however, once the table was left to be managed solely by dataTable, the problem was gone.
