    dotAll: boolean

    Returns a Boolean value indicating the state of the dotAll flag (s) used with a regular expression. Default is false. Read-only.

    flags: string

    Returns a string indicating the flags of the regular expression in question. This field is read-only. The characters in this string are sequenced and concatenated in the following order:

    • "g" for global
    • "i" for ignoreCase
    • "m" for multiline
    • "u" for unicode
    • "y" for sticky

    If no flags are set, the value is the empty string.

    ignoreCase: boolean

    Returns a Boolean value indicating the state of the ignoreCase flag (i) used with a regular expression. Default is false. Read-only.

    lastIndex: number

    下一次匹配开始的索引位置。

    The index at which to start the next match.

    multiline: boolean

    Returns a Boolean value indicating the state of the multiline flag (m) used with a regular expression. Default is false. Read-only.

    source: string

    Returns a copy of the text of the regular expression pattern. Read-only. The regExp argument is a Regular expression object. It can be a variable name or a literal.

    sticky: boolean

    Returns a Boolean value indicating the state of the sticky flag (y) used with a regular expression. Default is false. Read-only.

    unicode: boolean

    Returns a Boolean value indicating the state of the Unicode flag (u) used with a regular expression. Default is false. Read-only.
