936534 - l10n.js should use setAttribute for setting attributes of HTML elements

Status: RESOLVED DUPLICATE of bug 994290

(Firefox OS Graveyard :: Gaia::L10n, defect, P4)

Description

[Staś Małolepszy :stas]

Curerntly, l10n.js uses the element[property] syntax.  The proper approach is to use setAttribute().

To minimize the need for rebasing, let's fix this once bug 914414 lands.

This is a small patch.

A bigger one will go in bug 994290.

Before I review this, I'd like to see a patch against the Gaia repo, with relevant tests fixed.  For instance, in apps/gallery/test/unit/l10n/l10n_test.js you'll find:

      assert.equal(elem.prop, 'this is another property');
      assert.equal(elem.getAttribute('aria-label'), 'label via ARIA');

This should be unified to getAttribute, I believe.

r=me with a question.

Should we also change the line above the patch, which currently looks like the following?

  element[key.substr(0, pos)][key.substr(pos + 1)] = attr;

This could use setProperty for 'style', but not for 'dataset'.  It would also need a camelCase function to convert names of properties.

My take is 'no', and judging from the patch, you're against it as well, but I just want to make sure.

Thanks. Not many changes, cool.  Can you create a pull request for Gaia?

Actually, I'm afraid this is an r-.  I just realized that this will break all the foo.innerHTML we do in Gaia to insert HTML element in the translations.  Let's first fix bug 994357, get rid of innerHTML in the properties files, and revisit this bug.

No. That's bug 994290.

I just landed a patch for bug 994290 which basically fixes this. 

The only remaining piece is innerHTML exception which is going to be fixed by bug 994357.

I'm marking this bug as a DUPE of 994290.
