Link to test case:
I'm using this: https://editor.datatables.net/examples/advanced/parentChild.html
Description of problem:
When I press on row of first table, sometimes an error (altert) of wrong JSON is generated.
1) I would like it to remove that annoying error message via altert (I have 8 tables as children, and therefore I get it 8 times, and that doesn't make me very happy....). Is that possible?
2) I would like to handle the error. I haven't found the cause yet, but the error comes at randomo moments, and a second attempt works. Maybe it is a network problem. Either way, I would like to handle it so that it doesn't crash all the way through, but the user can have more convenient navigation. Ideally, if at the JSON error retries the download up to a maximum of 3 times 3 seconds apart. Would this be possible?

Do you get that error on the page you linked to? I've just tried clicking around on it and haven't seen it.
The proper answer is to never let the server return anything other than valid JSON. However, if you want to handle the error yourself you can do so using the
errModeparameter and provide your own error handler.There is no way for DataTables to do a retry itself. You would need to use
ajaxas a function and implement that yourself if that is a requirement.Allan
No, not on your page -- but on my site.
As mentioned, this is a communication error. Normally AJAX returns Error 500.
Do you have an example of how to use errMode?

Allan already gave you this link.
You've probably just missed the example - its at the bottom of the page I linked to.
