slice Method (String) (Windows Scripting - JScript)
Returns a section of a string.
Syntax
stringObj.slice(start, [end])
Arguments
stringObj
Required. A String object or literal.start
Required. The index to the beginning of the specified portion of stringObj.end
Optional. The index to the end of the specified portion of stringObj. The substring includes the characters up to, but not including, the character indicated by end. If this value is not specified, the substring continues to the end of stringObj.
Remarks
The slice method returns a String object containing the specified portion of stringObj.
The slice method copies up to, but not including, the character indicated by end.
If start is negative, it is treated as length + start where length is the length of the string. If end is negative, it is treated as length + end where length is the length of the string. If end is omitted, extraction continues to the end of stringObj. If end occurs before start, no characters are copied to the new string.
In the first example, the slice method returns the entire string. In the second example, the slice method returns the entire string, except for the last character.
