Member Enumeration Documentation

Bit flags that specify when the script is to be run.

Enumerator
kExecuteForEvent 

IE extension. If this is set, script will not run in browsers following HTML5, and will run at hard-to-describe time in IE.

Member Function Documentation

int net_instaweb::ScriptTagScanner::ExecutionMode ( const HtmlElement element) const

Returns which execution model attributes are set. Keep in mind, however, that HTML5 browsers will ignore kExecuteDefer and kExecuteAsync on elements without src=''

ScriptClassification net_instaweb::ScriptTagScanner::ParseScriptElement ( HtmlElement element,
HtmlElement::Attribute **  src 
)

Examines an HTML element and determine if it is a script. If it's not, it returns kNonScript and doesn't touch *src. If it is a script, it returns whether it is JavaScript or not, and sets *src to the src attribute (perhaps NULL)
