Can someone explain to me how the .on() works in this case?

$("input[type=range]").on("input", changeColor);

In the teacher's notes, instead of using .change(), we use .on("input", changeColor) for Chrome browser because .change() doesn't work for Chrome anymore. My question is, how to understand .on() method and its handler? What does "input" mean in (). I looked up in JQuery API but do not understand it very well. Thanks!

Hi Yijiao,

On is much more versatile than "change" because it looks for something you give it. "input" here is what you give it. for instance you could give it:

$("input[type=range]").on("click", changeColor);

And the changeColor will happen on a click.

But when you would give it:

$("input[type=range]").on("mouseenter", changeColor);

Would make it happen on the mouseenter instead of click.

So you can use on("change".... as well.
