Question

Somewhy line

$(document).on(eventType, handler);

throws an error

TypeError: $(...).on is not a function

What is done incorrectly?

PS: If that helps I’m including jquery lib with the following line

<script src="src/libs/jquery-1.6.1.js"> </script>

Answer 1

on was only included in jQuery 1.7 and above. For an alternative, use delegate (or if it’s possible, upgrade your jQuery).

Example of delegate:

$("table").delegate("td", "click", function() {
    $(this).toggleClass("chosen");
});
