Uncaught TypeError: Cannot read property 'aDataSort' of undefined

Question

i am working on pagination and i am using DataTables plugin , on some tables it\'s work but on some tables it gives error:

Uncaught TypeError: Cannot

Answer 1

I faced same issue and later found a typing mistake in "targets" property under columnDefs. See below example,

WRONG code below,

{
 "name": "firstName",
 "target": [1],
 "visible": false
}

Correction - missed 's' in targets :(

{
 "name": "firstName",
 "targets": [1],
 "visible": false
}

Looks like this error occurs when something causing columns not getting initialized. I checked that event 'preInit.dt' is not fired in this case.

Hope this helps someone.
