Sass giver en samling af praktiske funktioner til at manipulere strenge, men der er ingen funktion til at erstatte en substring med en anden streng. Her er en hurtig str-replacefunktion, hvis du nogensinde har brug for en.
/// Replace `$search` with `$replace` in `$string` /// @author Hugo Giraudel /// @param (String) $string - Initial string /// @param (String) $search - Substring to replace /// @param (String) $replace ('') - New value /// @return (String) - Updated string @function str-replace($string, $search, $replace: '') ( $index: str-index($string, $search); @if $index ( @return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace); ) @return $string; )Anvendelse:
.selector ( $string: 'The answer to life the universe and everything is 42.'; content: str-replace($string, 'e', 'xoxo'); )Resultat:
.selector ( content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42."; )
