String

Constructor

String(s)
new String(s)

Without the new operator, the String( ) function converts its argument to a string. With the new operator, it is a constructor that wraps the converted value in a String object.

Properties

length

The number of characters in the string. Read-only.

Methods

charAt( n )

Returns the character at position n in the string.

charCodeAt( n )

Returns the Unicode encoding of the character at position n in the string. JS 1.2; JScript 5.5; ECMA v1.

concat( value, ... )

Returns a new string that results from converting each of the arguments to a string and concatenating the resulting strings. JS 1.2; JScript 3.0; ECMA v3.

indexOf( substring, start )

Returns the position of the first occurrence of substring within this string that appears at or after the start position or -1 if no such occurrence is found. If start is omitted, 0 is used.

lastIndexOf( substring, start )

Returns the position of the last occurrence of substring within string that appears before the start position, or -1 if no such occurrence is found. If start is omitted, the string length is used.

match( regexp )

Matches this string against the specified regular expression and returns an array containing the match results or null if no match is found. If regexp is not a global regular expression, the returned array is the same as for the RegExp.exec( ) method. If regexp is global (has the “g” attribute), the elements of the returned array contain the text of each match found. ...
