示例1: nameGetter

// FIXME: You can get these properties, and set them (see customPut below),
// but you should also be able to enumerate them.
JSValue JSCSSStyleDeclaration::nameGetter(ExecState* exec, const Identifier& propertyName, const PropertySlot& slot)
{
    JSCSSStyleDeclaration* thisObj = static_cast<JSCSSStyleDeclaration*>(asObject(slot.slotBase()));

    // Set up pixelOrPos boolean to handle the fact that
    // pixelTop returns "CSS Top" as number value in unit pixels
    // posTop returns "CSS top" as number value in unit pixels _if_ its a
    // positioned element. if it is not a positioned element, return 0
    // from MSIE documentation FIXME: IMPLEMENT THAT (Dirk)
    bool pixelOrPos;
    String prop = cssPropertyName(propertyName, &pixelOrPos);
    RefPtr<CSSValue> v = thisObj->impl()->getPropertyCSSValue(prop);
    if (v) {
        if (pixelOrPos && v->cssValueType() == CSSValue::CSS_PRIMITIVE_VALUE)
            return jsNumber(exec, static_pointer_cast<CSSPrimitiveValue>(v)->getFloatValue(CSSPrimitiveValue::CSS_PX));
        return jsStringOrNull(exec, v->cssText());
    }

    // If the property is a shorthand property (such as "padding"), 
    // it can only be accessed using getPropertyValue.

    // Make the SVG 'filter' attribute undetectable, to avoid confusion with the IE 'filter' attribute.
    if (propertyName == "filter")
        return StringObjectThatMasqueradesAsUndefined::create(exec, thisObj->impl()->getPropertyValue(prop));

    return jsString(exec, thisObj->impl()->getPropertyValue(prop));
}

示例2: getOwnPropertyNames

void JSCSSStyleDeclaration::getOwnPropertyNames(JSObject* object, ExecState* exec, PropertyNameArray& propertyNames, EnumerationMode mode)
{
    JSCSSStyleDeclaration* thisObject = jsCast<JSCSSStyleDeclaration*>(object);
    ASSERT_GC_OBJECT_INHERITS(thisObject, info());

    unsigned length = thisObject->impl()->length();
    for (unsigned i = 0; i < length; ++i)
        propertyNames.add(Identifier::from(exec, i));

    static Identifier* propertyIdentifiers = 0;
    if (!propertyIdentifiers) {
        Vector<String, numCSSProperties> jsPropertyNames;
        for (int id = firstCSSProperty; id < firstCSSProperty + numCSSProperties; ++id)
            jsPropertyNames.append(getJSPropertyName(static_cast<CSSPropertyID>(id)));
        sort(jsPropertyNames.begin(), jsPropertyNames.end(), WTF::codePointCompareLessThan);

        propertyIdentifiers = new Identifier[numCSSProperties];
        for (int i = 0; i < numCSSProperties; ++i)
            propertyIdentifiers[i] = Identifier(exec, jsPropertyNames[i].impl());
    }

    for (int i = 0; i < numCSSProperties; ++i)
        propertyNames.add(propertyIdentifiers[i]);

    Base::getOwnPropertyNames(thisObject, exec, propertyNames, mode);
}
