I very much understood what you said and tried it. but I'm getting null value
from cookie
var tempRows = new Array();
tempRows.push({name:"vj",rollNo:10});
tempRows.push({name:"vj",rollNo:10});
var v = objectToQueryString(tempRows,"&");
alert(v); // which prints
_name##"vj"**rollNo##10&........&each=function%20........
but when I set the cookie to $.cookie('myCookie', v);
and later when I tried to retrieve cookie like alert($.cookie('myCookie'))
prints the null value.
Not sure why this is happening.. Can u tell me why this happening.
Regards,
Vijay
