Java Script Associates Arrays

Hi Guys,
              It is always good to have a associated  arrays instead of plain arrays in java java script. The below sample code demonstrates the use of java script associated arrays.

 var gameNdPlayesr= new Array();

 gameNdPlayesr["cricket"]="Sachin";
 gameNdPlayesr["football"]="Maradona";
 gameNdPlayesr["golf"]="Woods";

 var sport=confirm("Please enter your favourite sport");

 alert( "The king of "+ sport+" is "+gameNdPlayesr[sport]);

Thanks,

JavaScript random string of specific length

Hi Guys,
             The below java script code generates a random string of specific length.

function getRandomByLength(randomStrLength) {

       var chars =        "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
      var randomstring = '';
      for (var i=0; i<randomStrLength; i++) {
      var rnum = Math.floor(Math.random() * chars.length);
      randomstring += chars.substring(rnum,rnum+1);
    }
        return randomstring;
}
