Javascript take script server side

Question

How can I take this code

<script>
var arr = [<%= myArray %>+<%= my2Array %>]; 
var sorted_arr = arr.sort(); 
var results = []; 
for (var i = 0; i < arr.length - 1; i += 1) { 
        if (sorted_arr[i + 1] == sorted_arr[i]) { 
                results.push(sorted_arr[i]); 
        } 
} 
 document.write(results +"<br />");
</script>

and convert it to <% the above script %> and keep the functionality?

Why does the script work in the script tag but not when I place it in <% %>

    <%
var arr = [myArray+my2Array]; 
var sorted_arr = arr.sort(); 
var results = []; 
for (var i = 0; i < arr.length - 1; i += 1) { 
        if (sorted_arr[i + 1] == sorted_arr[i]) { 
                results.push(sorted_arr[i]); 
        } 
} 
%>
<%= results %>

If I use it like this the results are returned as empty

I suspect the reason why it is not working is because the results value is not getting populates... In the script version it gets the time to populate and loop

Server side scripts are not written in javascript. What's the language you are using to write server scripts? — Darin Dimitrov

What do myArray and my2Array contain? - are they JScript arrays? I don't think you can just add them — meouw

It is text values - myArray and my2Array = 'this','is','a','test' — Gerald Ferreira

If those are ASP arrays, simply outputting them into the page won't work the way you expect. You'll need to have some ASP code loop over each array and echo the variables - so that when the page is sent to the client, it parses as valid JavaScript. — Arkaaito

If you want to run your code server side you need to change the line

var arr = [myArray+my2Array];

to

var arr = (myArray+','+my2Array).split(',');

var arr = (myArray+my2Array).split(','); var sorted_arr = arr.sort(); var results = []; for (var i = 0; i < arr.length - 1; i += 1) { if (sorted_arr[i + 1] == sorted_arr[i]) { results.push(sorted_arr[i]); } } Works 100% thanks meouw!
