when i run in chrome iam getting this error- Cannot call method 'properties' of 
undefined .... how to resolve it?
I wrote in my jsp as:

<script type="text/javascript">
jQuery.i18n.properties({
                name:'MessagesBundle', 
                path:'bundle/', 
                mode:'both',
                language:'en_US', 
                callback: function() {
                    // We specified mode: 'both' so translated values will be
                    // available as JS vars/functions and as a map

                    // Accessing a simple value through the map
                    jQuery.i18n.prop('msg_hello');
                    // Accessing a value with placeholders through the map
                    jQuery.i18n.prop('msg_complex', 'John');

                    // Accessing a simple value through a JS variable
                    alert(msg_hello +' '+ msg_world);
                    // Accessing a value with placeholders through a JS function
                    alert(msg_complex('John'));
                }
            });
</script>
