global Property


rgExp.global

rgExp: Required. An instance of a Regular Expression object.

The global property is read-only, and returns true if the global flag is set for a regular expression, and returns false if it is not. The default value is false.

The global flag, when used, indicates that a search should find all occurrences of the pattern within the searched string, not just the first one. This is also known as global matching.

The following example illustrates the use of the global property.

В	Copy Code
function RegExpPropDemo(re : RegExp) { print("Regular expression: " + re); print("global: " + re.global); print("ignoreCase: " + re.ignoreCase); print("multiline: " + re.multiline); print(); }; // Some regular expression to test the function. var re1 : RegExp = new RegExp("the","i"); // Use the constructor. var re2 = /\w+/gm; // Use a literal. RegExpPropDemo(re1); RegExpPropDemo(re2); RegExpPropDemo(/^\s*$/im);

В

Copy Code

function RegExpPropDemo(re : RegExp) {
   print("Regular expression: " + re);
   print("global:     " + re.global);
   print("ignoreCase: " + re.ignoreCase);
   print("multiline:  " + re.multiline);
   print();
};

// Some regular expression to test the function.
var re1 : RegExp = new RegExp("the","i");  // Use the constructor.
var re2 = /\w+/gm;                         // Use a literal.
RegExpPropDemo(re1);
RegExpPropDemo(re2);
RegExpPropDemo(/^\s*$/im);

The output of this program is:

В	Copy Code
Regular expression: /the/i global: false ignoreCase: true multiline: false Regular expression: /\w+/gm global: true ignoreCase: false multiline: true Regular expression: /^\s*$/im global: false ignoreCase: true multiline: true
