Applies To: Regular Expression Object
The exec method 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. |
Return value
Returns an array if there is a match or null if there is no match.
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);
}
document.write(ExecDemo());
|
 To run the code, paste it into JavaScript Editor, and click the Execute button.
