示例1: switch
void JSHTMLMetaElement::putValueProperty(ExecState* exec, int token, JSValue* value)
{
switch (token) {
case ContentAttrNum: {
HTMLMetaElement* imp = static_cast<HTMLMetaElement*>(impl());
imp->setContent(valueToStringWithNullCheck(exec, value));
break;
}
case HttpEquivAttrNum: {
HTMLMetaElement* imp = static_cast<HTMLMetaElement*>(impl());
imp->setHttpEquiv(valueToStringWithNullCheck(exec, value));
break;
}
case NameAttrNum: {
HTMLMetaElement* imp = static_cast<HTMLMetaElement*>(impl());
imp->setName(valueToStringWithNullCheck(exec, value));
break;
}
case SchemeAttrNum: {
HTMLMetaElement* imp = static_cast<HTMLMetaElement*>(impl());
imp->setScheme(valueToStringWithNullCheck(exec, value));
break;
}
}
}示例2: metaData
/*!
\since 4.5
\brief Returns the meta data in this frame as a QMultiMap
The meta data consists of the name and content attributes of the
of the \c{<meta>} tags in the HTML document.
For example:
\code
<html>
<head>
<meta name="description" content="This document is a tutorial about Qt development">
<meta name="keywords" content="Qt, WebKit, Programming">
</head>
...
</html>
\endcode
Given the above HTML code the metaData() function will return a map with two entries:
\table
\header \o Key
\o Value
\row \o "description"
\o "This document is a tutorial about Qt development"
\row \o "keywords"
\o "Qt, WebKit, Programming"
\endtable
This function returns a multi map to support multiple meta tags with the same attribute name.
