Bug 108263 – formMethod to have empty string as default value and 'get' as invalid.

• Component: Forms
• Status: RESOLVED FIXED

[Vineet Chaudhary (vineetc)]

Specification: http://www.whatwg.org/specs/web-apps/current-work/#form-submission-0
             : http://www.w3.org/html/wg/drafts/html/master/forms.html#attr-fs-formmethod
Mozilla bug  : https://bugzilla.mozilla.org/show_bug.cgi?id=787095

The spec says formmethod should only have an invalid value default, not a missing value default.
Tests affected : fast/forms/submit-form-attributes.html

If this change makes sense then similar is also applies to formenctype.

Looks OK, but needs a little improvement.

> Source/WebCore/html/HTMLFormControlElement.cpp:90
> +    String formMethod = fastGetAttribute(formmethodAttr);

The result of fastGetAttribute is const AtomicString&, not String. Putting it in a String creates unnecessary reference count churn.

> Source/WebCore/html/HTMLFormControlElement.cpp:92
> +        return "";

The efficient way to return an empty string is emptyString(). Returning "" will result in extra code including a call to strlen.

Why did you change this line to String(), not emptyString() Darin recommended?

> LayoutTests/fast/forms/formmethod-attribute-test.html:21
> +shouldBe('ip1.formMethod', '""');

Please use shouldBeEqualToString to avoid ugly nested quotes.

> LayoutTests/fast/forms/formmethod-attribute-test.html:28
> +shouldBe('ip2.formMethod', '"get"');
> +shouldBe('ip2.getAttribute("formmethod")', '""');

ditto.

> LayoutTests/fast/forms/formmethod-attribute-test.html:34
> +shouldBe('ip3.formMethod', '"post"');
> +shouldBe('ip3.getAttribute("formmethod")', '"post"');

ditto.

> LayoutTests/fast/forms/formmethod-attribute-test.html:40
> +shouldBe('ip4.formMethod', '"get"');
> +shouldBe('ip4.getAttribute("formmethod")', '"get"');

ditto.

> LayoutTests/fast/forms/formmethod-attribute-test.html:46
> +shouldBe('ip5.formMethod', '"get"');
> +shouldBe('ip5.getAttribute("formmethod")', '"foo"');

ditto.

Please put the description line first.

I interpreted it wrong. Done!!

Done. There are still calls shouldBe() instead of shouldBeEqualToString()
in another file ../forms/submit-form-attributes.html in this patch but I wasn't sure to change those
but I can do that in followup patch for formenctype if required.
