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)
