The global
accessor property indicates whether or not the g
flag is used with the regular expression.
The global
accessor property indicates whether or not the g
flag is used with the regular expression.
RegExp.prototype.global
has the value true
if the g
flag was used; otherwise, false
. The g
flag indicates that the regular expression should be tested against all possible matches in a string. Each call to exec()
will update its lastIndex
property, so that the next call to exec()
will start at the next character.
Some methods, such as String.prototype.matchAll()
and String.prototype.replaceAll()
, will validate that, if the parameter is a regex, it is global. The regex's @@match
and @@replace
methods (called by String.prototype.match()
and String.prototype.replace()
) would also have different behaviors when the regex is global.
The set accessor of global
is undefined
. You cannot change this property directly.
const regex = /foo/g; console.log(regex.global); // true const str = 'fooexamplefoo'; const str1 = str.replace(regex, ''); console.log(str1); // Output: example const regex1 = /foo/; const str2 = str.replace(regex1, ''); console.log(str2); // Output: examplefoo
