How can I get the session values from an external.js by using Struts2 jQuery

Question

I need to recover a value from session in my external JS. Before, I did it in a script embedded in the JSP with this lines and it worked properly:

$(window).load(function(){
    var selectedServer = "<s:property value='%{#session.selectedServer}'/>";
    var selectedMarket = "<s:property value='%{#session.selectedMarket}'/>";
});

but now, I want to do it from an external JS and an alert(selectedServer); after these lines, show me the literal: <s:property value='%{#session.selectedServer}'/>, but not the value.

Is the syntax different in an external.js?

You can use javascript global variables in the external script, or use function parameters to pass the values that you should obtain in the JSP to the external function.

<script>
    var selectedServer = "<s:property value='%{#session.selectedServer}'/>";
    var selectedMarket = "<s:property value='%{#session.selectedMarket}'/>";
</script>

function(selectedServer, selectedMarket){
}
