示例1: updateFromElement

// If we're not making renderers for the page, then don't load images. We don't want to slow
// down the raw HTML parsing case by loading images we don't intend to display.
Element* elem = element();
Document* doc = elem->document();
if (!doc->renderer())
return;
AtomicString attr = elem->getAttribute(elem->hasLocalName(objectTag) ? dataAttr : srcAttr);
// Treat a lack of src or empty string for src as no image at all.
CachedImage *newImage = 0;
if (!attr.isEmpty()) {
if (m_loadManually) {
doc->docLoader()->setAutoLoadImages(false);
newImage = new CachedImage(doc->docLoader(), parseURL(attr), false /* not for cache */);
