The value of global
is a Boolean
and 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. A regular expression defined as both global
("g
") and sticky
("y
") will ignore the global
flag and perform sticky matches.
You cannot change this property directly.
var regex = new RegExp('foo', 'g'); console.log(regex.global); // true var str = 'fooexamplefoo'; var str1 = str.replace(regex, ''); console.log(str1); // Output: example var regex1 = new RegExp('foo'); var str2 = str.replace(regex1, ''); console.log(str2); // Output: examplefoo
