Description
Executes a search for a match in a specified string.
Syntax
rgexp.exec(str)

The exec method syntax has these parts:

Part Description
rgexp Required. A Regular Expression object. Can be a variable name or a literal.
str Required. The string to perform a search on.

Remarks
The results of an exec method search are placed into an array.

If the exec method does not find a match, it returns null. If it finds one or more matches, the exec method returns an array, and the RegExp object is updated to reflect the results of the search.

The following example illustrates the use of the exec method:

function ExecDemo()
{
  var s = "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPp"
  var r = new RegExp("g", "i");
  var a = r.exec(s);
  document.write(a);
  r.compile("g");
  var a = r.exec(s);
  document.write(a);
}
