The split() method is used to split a string into an array of strings.
split()方法用于将一个字符串分解成一个数组对象。
stringObject.split(separator, howmany) |
Parameter 参数 | Description 注释 |
---|---|
separator 分隔符 | Required. Specifies the character, regular expression, or substring that is used to determine where to split the string 必选项。指定的字符,字符串或正则表达式,作为分解用的分隔符 |
howmany 次数 | Optional. Specify how many times split should occur. Must be a numeric value 可选项。指定分解的次数 |
Note: If an empty string ("") is used as the separator, the string is split between each character.
