java script error in opera for list keyword object

Today i faced a tricky problem in opera with java script.

i had created a object in javascript with name list.
var list = {
create : function () {alert('vinod');
}
}
and i called the list.save function in my code. In FF and chrome it is working fine. But in opera it was throwing the following error

javascript URL encode and decode functions


1

jscode :
2 function encode() {
3 var obj = document.getElementById('dencoder');
var unencoded = obj.value;
obj.value = encodeURIComponent(unencoded);
}
