Adding Left and Right Functionality in JavaScript

Adding Left and Right Functionality in JavaScript

JavaScript does not offer Left and Right functions. Use the following functions to extract the left or the right part of a string.

 function Left(str, n){	if (n  String(str).length)	    return str;	else	    return String(str).substring(0,n);}function Right(str, n){    if (n  String(str).length)       return str;    else {       var iLen = String(str).length;       return String(str).substring(iLen, iLen - n);    }}
