SVG script element. A ‘script’ element is equivalent to the ‘ script’ element in HTML and thus is the place for scripts (e.g., ECMAScript). Any functions defined within any ‘script’ element have a "global" scope across the entire current document.

public method

Matches(String)

Returns the specificity (>=0) of the match with the selector string or -1 if there is no match.

A selector's specificity is calculated as follows:

1. Count the number of ID selectors in the selector (= a)
2. Count the number of class selectors, attributes selectors, and pseudo-classes in the selector (= b)
3. Count the number of type selectors and pseudo-elements in the selector (= c)
4. Ignore the universal selector
5. Selectors inside the negation pseudo-class are counted like any other, but the negation itself does not count as a pseudo-class.


















Concatenating the three numbers a-b-c (in a number system with a large base) gives the specificity.
