Javascript function startsWith
String.prototype.startsWith = function(str)
{return (this.match("^"+str)==str)}
Javascript function endsWith
String.prototype.endsWith = function(str)
{return (this.match(str+"$")==str)}
Usage:
var myStr = “ Earth is a beautiful planet ”;
var myStr2 = myStr.trim();
//==“Earth is a beautiful planet”;
if (myStr2.startsWith(“Earth”)) // returns TRUE
if (myStr2.endsWith(“planet”)) // returns TRUE
if (myStr.startsWith(“Earth”))
// returns FALSE due to the leading spaces…
if (myStr.endsWith(“planet”))
// returns FALSE due to trailing spaces…
