JavaScript global Property: RegExp Object

Last update on August 19 2022 21:50:37 (UTC/GMT +8 hours)

The global property of the RegExp object specifies whether the g flag is used with the regular expression or not. If used, the regular expression is tested against all possible matches in a string. The value of the global is true if the "g" flag is used; otherwise false.

Version

Implemented in JavaScript 1.2

Syntax

RegExp.global
