Thanks for taking the time to contribute to the jQuery project by writing a bug report.

As you didn't provide the test case (or any of the other data) requested in the bug reporting guidelines, I went ahead and made this test case which works for me.

Thus please report back with a reduced test case, that reproduces the issue you are experiencing, on So that we can reopen this ticket and investigate the issue further.

I ran into the same issue, although it isn't a bug, it's not very clear either.

When the dataType is 'json' and your dataFilter returns JSON you will get 'null' back to your success function. When you return a string, it will be parsed and passed on to the success function.

So when you want to have the result of the dataFilter function passed on as is, then you need to set the dataType to 'text'.

Here are examples on jsFiddle:

I don't agree this is a low priority bug. This is a breaking change compared to the previous jQuery versions. when dataFilter is passed as string, and returns a parsed JSON object, it should just return it "as is", instead of returning null.
