HTMLOptionElement::value() returns incorrect value

Summary HTMLOptionElement::value() returns incorrect value
Kent Tamura
Reported 2009-07-28 02:35:35 PDT
Suppose that we have 4 OPTION elements as follows: <option id="o1">text</option> <option id="o2" value="value">text</option> <option id="o3" label="label">text</option> <option id="o4" value="value" label="label">text</option> The current WebKit returns the following values for .value and .label: o1: value=text label= o2: value=value label= o3: value=label label=label o4: value=value label=label Apparently the value of o3 is incorrect. It should be "text" or "". I think r40130 introduced this bug. FYI: On Firefox 3.5 and Opera 10: o1: value=text label= o2: value=value label= o3: value=text label=label o4: value=value label=label On IE8: o1: value= label= o2: value=value label= o3: value= label=label o4: value=value label=label As for HTML5, .value and .label just reflect their attribute values. http://www.whatwg.org/specs/web-apps/current-work/multipage/forms.html#dom-option-value So IE8 behavior is compliant.

Correction: In the description, IE8 meant IE7. IE8's behavior is exactly same as Firefox 3.5 and Opera 10.

I like the patch, though we clearly need a better naming scheme here, it's confusing. Or a detailed ChangeLog describing why it is as it is :-) r-, for the ChangeLog & "const String&" issue.

Thank you for the comments. I have updated the patch. - Improve ChangeLogs - Use const String& for a parameter - Rename method names, and restructuring some methods.
