        return false
        }

c.parent("li").addClass("active");
b=a(c.attr("href"));
a(".help-tab-content").not(b).removeClass("active").hide();

});

Answer 1

From the docs:

As of jQuery 1.7, .delegate() has been superseded by the .on() method

Although .delegate is still there and should work, you should use .on instead:

a(".contextual-help-tabs").on("click focus", "a", function(d) {
  ...
});
