PROPERTY: RegExp::$1, ..., $9
These are properties containing parenthesized substrings (if any) from a regular expression.
The number of parenthesized substrings is unlimited, but these properties only hold
the last nine. All parenthesized substring, however, can be accessed throught the
returned array's indexes. When used as the second argument of the String.replace
method, these properties do not require RegExp. before them.
In the following example, the day and month parts of a date written in British format
are rearranged to American style:
Code:
myRegExp = /(\d{2})\W(\d{2})\W(\d{4})/
dateString = "25/12/1997"
newString = dateString.replace(myRegExp, "$2/$1/$3")
document.write(newString)
Output:
12/25/1997
NOTE:
Because input is static, it is always used as RegExp.input
