how to share constants between Java and Javascript

Question

I have in my java classes static variables CONSTANT_1, CONSTANT_2...
What is the best way to share these constants with my javascript functions or if there is a JQuery plugin for this.

Till now the only solution I can think of, is an ajax call in the beginning, to send these static variables to the client.

Thanks

Answer 1

I dont know whether this the best way or not, but it works.

var constant1=<%=class.CONSTANT_1%>;

Answer 2

you can set this static variable in a hidden field, then you can access it by javascript using this hidden field

<input type="hidden" value="<your static variable>" id="staticVariable" />
<script type="text/javascript">
    function getStaticField(){
        return document.getElementById("staticVariable").value;
    }
</script>
