jquery - How to debug JavaScript closure? -


  1. the question why debug function, how know closure content function refer to?

    i'm aware google chrome display closure in "scope variables" section, other browsers? (updated: ff has similar thing doesn't call "closure" local variables)

  2. motivation of first question coming along while reading <learning jquery,3rd edition> - appendix a.

    at page 355, author saying following code fragment cause memory leak @ ie because of loop reference(click handler refer closure content has dom button).

    i'm curious whether case debug click handler closure content.however google chrome doesn't show closure variable.

    thus i'm wondering how author know loop reference issue..

$(document).ready(function() { var button = document.getelementbyid('button-1'); button.onclick = function() { $.print('hello'); return false; }; });

thank you.
