javascript - What script goes with which part of the HTML? -

is there way find out script being used elements of html.

for example if want find out script went creating drop down menu, know how find html , css menu, not javascript (or whatever script used).

i using web developer chrome extension javascript of pages i'm interested in, these huge documents, how know functions/variables/etc link part of html?

it's possible chrome's dev tools of you... can right-click on element, select "inspect element" option. then, right-click on html node within dom inspector , select "break on..." option , select (e.g.) "subtree modifications" , "attribute modifications".

chrome stop javascript execution when drop down menu you're interested in changes. able explore javascript used.

of course, of little if javascript minified...
