There is no built in functions inside Jscript to extract left or right substring from specific string… the following functions are customized to do so..
function LeftSubString(stringValue, length) { if (length <= 0) return ""; else if (length > String(stringValue).length) return stringValue; else return String(stringValue).substring(0,length); }
function RightSubString(stringValue, length){ if (length <= 0) return ""; else if (length > String(stringValue).length) return stringValue; else { var iLen = String(stringValue).length; return String(stringValue).substring(iLen, iLen – length); } }
