slice Method (String)

Description

Returns a section of a string.

Syntax

stringObj.slice(start, [end])

The slice method syntax has these parts:

Part	Description
stringObj	Required. A String object or literal.
start	Required. The zero-based index of the beginning of the specified portion of stringObj.
end	Optional. The zero-based index of the end of the specified portion of stringObj.

Remarks

The slice method returns a String object containing the specified portion of stringObj.

If negative, end indicates an offset from the end of stringObj. In addition, it is not zero-based. If omitted, extraction continues to the end of stringObj.

In the example that follows, the two uses of the slice method return the same thing. Negative one in the second example points to the last character in str1 as the ending point:

str1.slice(0)
str2.slice(0,-1)
