global is a read-only boolean property of RegExp objects. It specifies whether a particular regular expression performs global matching, i.e., whether it was created with the "g" attribute.
Its syntax is as follows −
RegExpObject.global
Returns "TRUE" if the "g" modifier is set, "FALSE" otherwise.
Try the following example program.
<html> <head> <title>JavaScript RegExp global Property</title> </head> <body> <script type="text/javascript"> var re = new RegExp( "string" ); if ( re.global ){ document.write("Test1 - Global property is set"); } else { document.write("Test1 - Global property is not set"); } re = new RegExp( "string", "g" ); if ( re.global ){ document.write("<br />Test2 - Global property is set"); } else { document.write("<br />Test2 - Global property is not set"); } </script> </body> </html>
Test1 - Global property is not set Test2 - Global property is set
