The dotAll
accessor property of RegExp
instances returns whether or not the s
flag is used with this regular expression.
RegExp.prototype.dotAll
has the value true
if the s
flag was used; otherwise, false
. The s
flag indicates that the dot special character (.
) should additionally match the following line terminator ("newline") characters in a string, which it would not match otherwise:
\n
)\r
)This effectively means the dot will match any character on the Unicode Basic Multilingual Plane (BMP). To allow it to match astral characters, the u
(unicode) flag should be used. Using both flags in conjunction allows the dot to match any Unicode character, without exceptions.
The set accessor of dotAll
is undefined
. You cannot change this property directly.
const str1 = "bar\nexample foo example"; const regex1 = /bar.example/s; console.log(regex1.dotAll); // true console.log(str1.replace(regex1, "")); // foo example const str2 = "bar\nexample foo example"; const regex2 = /bar.example/; console.log(regex2.dotAll); // false console.log(str2.replace(regex2, "")); // bar // example foo example
