String.split(regex, flags) | Liste |
Argument | Type | Détails |
---|
ceci : string | Chaîne | Chaîne à fractionner. |
regex | Chaîne | Expression régulière sur laquelle effectuer la division. Si l'expression régulière est une chaîne vide, la chaîne d'entrée est divisée en caractères individuels. |
flags | Chaîne, valeur par défaut : "" | Chaîne spécifiant l'indicateur d'expression régulière : "i" (ignorer la casse). |

// 'i' tells split to ignore case.

// Split on 'b' or 'c'

// Split on 'BA' or 'c'

// ^ as the first character in [] excludes.

// Splitting on characters that are special to split.
