JavaScript String method: match()
[this page | pdf | back links]
The match() method (when applied to a JavaScript
string) searches
the string for regular
expression matches, and returns them as an array. If the regular expression
does not include a g modifier
(corresponding to a global search), match
only returns the first match. If no match is found then the method returns null.
It
has the following syntax with the following parameters:
string.match(regexpression)
