Bug 97318 – DateTimeNumericFieldElement should use Localizer functions.

• Status: RESOLVED
• Resolution: FIXED
• Component: Forms

[Kent Tamura]

DateTimeNumericFieldElement should use Localizer functions.

In the result of fast/forms/time-multiple-fields/time-multiple-fields-localization.html, "ar" locale doesn't use native digits at all.

[Kent Tamura]

Passing a Localizer for the host <input> to DateTimeNumericFieldElement is troublesome.
We had better introduce Element::computeInheritedLanguageOverShadowBoundary() or something.

I think it is better to have a new function in FieldOwner interface, e.g. FieldOwner::localizer().
Implementation of DateTimeEditElement localizer() calls DateTimeEditElement::EditControlOwner::localizer().

We know DateTimeFieldElement always in shadow tree, but it is better to reduce number of assumptions.

Is it better to have DateTimeEditOwner::localizeNumber() API?
We don't need to have full Localizer in DateTimeNumericFieldElement.
Also, we may need to rename "Localizer" sometimes in future. So, reducing number of reference to Localizer will help us.

I wanted to avoid it (See Comment #1) because we need to check nullness of m_fieldOwner and m_editControlOwner and to return fallback Localizer.
Using locale identifier strings instead of Localizer objects is simpler (Patch 2).

I don't think so. We'll need other Localizer functions in the future.

Can the return value be const?

It can't. Localizer member functions are not const because of lazy initialization, and we need to call them.

I think it is better that EditControlOwner returns Localizer instead of locale identifier to improve modulelaity and to hide how to get Localizer in DateTimeFieldElement.
