- Syntax:
- RegExp.input
This property is a string against which a regular expression is matched.
This property is a string against which a
regular expression is matched. Input is static and is therefore always used as
RegExp.input. If this property has a value, that value is used by default
as the argument of the exec and test methods, unless another
argument is provided. When no argument is provided with these methods, the
script or browser can preset the input method as follows:
Where a TEXT form element calls an event handler, it is set to the
value of the contained text.
Where a TEXTAREA form element calls an
event handler, it is set to the value of the contained text and the
multiline property is set to true so that the match can be executed
throughout the text.
Where a SELECT form element calls an event
handler, it is set to the value of the selected text.
Use the href property to change a link. Where a
Link object calls an event handler, it is set to the value of the text
between the <A> tags.
The value of input clears after the
event handler completes.
