ignoreCase Property


rgExp.ignoreCase

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

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

The ignoreCase flag, when used, indicates that a search should ignore case sensitivity when matching the pattern within the searched string.

The following example illustrates the use of the ignoreCase 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
