col.sTitle.replace is not a function

prasadnadendla

I am using title of type function instead of string. It throws the above error during sorting.

Using latest version of data-tables.net package along with the licensed version of editor

Happy to take a look at a test case showing the issue so I can help resolve it or patch DataTables if needed.

@allan Thank you for your prompt response. After examining the source, it appears that there is no logic to perform type checking before treating it as a string replacement.

I put together this little example, and yes I see the issue. However, columns.title does document that it should be given as a string. If you are passing in a number, add .toString() after the number or just + '' and it should work as expected.

edit Sorry - you are using a function. Yes, that isn't supported at all for the title. You'll need to execute the function at initialisation time to get the value (a string).

Thanks @allan. Certainly, I understand now. Apologies for the confusion, as I initially thought it supported function types. Could you please guide me on how to add a custom element to the header without it being affected by the sorting click?

Put your span, or whatever tag you want into the header and then stop the event from bubbling. Here is a little example.
