How can I find unsupported / deprecated jQuery functions in a JS file?

Question

Is there a website or a tool where I can enter some jQuery code and it will show me whether unsupported / deprecated functions are used in this code?

This would be really nice...

Answer 1

jQuery lint should do the job:

Answer 2

jQuery now provide a migrate plugin (1.4.1 & 3.0+) to display warnings on any use of deprecated functions in browser console:
