RegExp.prototype.multiline

¥Description

如果使用了 m 标志，则 RegExp.prototype.multiline 的值为 true；否则，false。m 标志指示多行输入字符串应被视为多行。例如，如果使用 m，则 ^ 和 $ 从仅匹配整个字符串的开头或结尾更改为匹配字符串内任何行的开头或结尾。

¥RegExp.prototype.multiline has the value true if the m flag was used; otherwise, false. The m flag indicates that a multiline input string should be treated as multiple lines. For example, if m is used, ^ and $ change from matching at only the start or end of the entire string to the start or end of any line within the string.

multiline 的集合访问器是 undefined。你不能直接更改此属性。

¥The set accessor of multiline is undefined. You cannot change this property directly.
