input Property ($


//Syntax 1 {RegExp \| reArray}.input //Syntax 2 RegExp.$_ //The $_ property may be used as shorthand for the input property //for the RegExp object.

reArray: Required. An array returned by the exec method of a Regular Expression object.

The value of input property is the string against which a regular expression search was performed.

The initial value of the RegExp.input property is an empty string, "". Its value is read-only and changes whenever a successful match is made.

Note
The properties of the RegExp object are not available when running in fast mode, the default for JScript. To compile a program from the command line that uses these properties, you must turn off the fast option by using /fast-. It is not safe to turn off the fast option in ASP.NET because of threading issues.

The following example illustrates the use of the input property:

В	Copy Code
var str : String = "A test string."; var re : RegExp = new RegExp("\\w+","ig"); var arr : Array = re.exec(str); print("The string used for the match was: " + arr.input);

The output of this program is:

В	Copy Code
The string used for the match was: A test string.
