substr Method (Windows Scripting - JScript)

  • Article

 

Returns a substring beginning at a specified location and having a specified length.

Syntax

stringvar.substr(start [, length ])

Arguments

  • stringvar
    Required. A string literal or String object from which the substring is extracted.

  • start
    Required. The starting position of the desired substring. The index of the first character in the string is zero.

  • length
    Optional. The number of characters to include in the returned substring.

Remarks

If length is zero or negative, an empty string is returned. If not specified, the substring continues to the end of stringvar.

The following example illustrates the use of the substr method.

function SubstrDemo(){
   var s = "The quick brown fox jumps over the lazy dog.";
// Get substring.
   var ss = s.substr(10, 5);  
// Returns "brown".
   return(ss);                
}
