Let's say you have written some jQuery or a jQuery-plugin. Is there a way to check which (minimal) version of jQuery is required for the code to run?

    it depends on the function you using if you are using function which in not in new version than you have to use older version list fo deprecated function http://api.jquery.com/category/deprecated/ **for example** As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. – NullPoiиteя Dec 20 '12 at 14:16
  • You can use feature detection to make sure a certain jQuery method is available for use. For example to check for jQuery 1.7+ you could check for `on()`: `var jq17 = typeof($().on) == "function"` – Rory McCrossan Dec 20 '12 at 14:18
  • @NullPointer was the only one who understood what I am asking. I want to parse a peace of code and the function should output something like "jQuery v1.4.3 is needed to run this code". – Sebastian Sebald Dec 23 '12 at 14:23
