625724 - Bank of America login page has strict mode issues

Status: RESOLVED DUPLICATE of bug 639190

(Tech Evangelism Graveyard :: English US, defect)

Description

[Boris Zbarsky [:bzbarsky]]

Relevant bits:

"use strict";
.....
boa = window.boa || {};

That throws; "boa" is undeclared.

Unfortunately, getting at the page involves having a username for an account with Bank of America.

I don't _think_ this keeps me from logging in (hard to tell because right this second I can't log in in either Firefox 4 or Firefox 3.6 or Safari; I think the site is generally having issues).  But looking into the login issue made me notice the above.

Boris, can you spot a well-known JS library that has "use strict" and in fact conforms to strict mode, but which was carelessly concatenated to other sources that do not conform?

Nope.  Here's the full code from the "use strict" to the failure point:

  "use strict";
  (function ($) {
      $(function () {
          $("input:text").focus(function () {
              if ($(this).attr("readonly") != true) {
                  $(this).val("")
              }
          });
          $("input:text").blur(function () {
              if (($(this).val() === "") || ($(this).val() === " ")) {
                  $(this).val($(this).attr("title"))
              }
          })
      })
  })(jQuery);
  boa = window.boa || {};

And logging in works again now, so this failure is at least nonfatal.
