Problem with unobtrusive JavaScript

Hello rancheros,
I would like to ask you about a problem of unobtrusive javascript.

I know it's very good to separate behavior from structure but if I put events code in an external file for example, when in the future I will look again the HTML code, I will have problems to remember where my functions are invocate.

For example, if I have the below HTML code:

and in an external javascript file I have:

it's very difficult to know that pic1 has a javascript function.

How do you resolve this type of problem?

Thanks
KK

You don't. If you don't want to keep the behavior separate from the structure, you don't want to use Unobtrusive JavaScript. It's kind of like asking how you can eat beef and still be a vegetarian.

The same thing applies to CSS. You can't see what styles are applied to the elements by just looking at the structure. You need to look at the CSS. In Unobtrusive JavaScript, you need to look at the script to know what behavior is applied.
