Jsp variables to javascript array, for loop dont work.

Question

This works fine. con.getmake passes a different variable each time to the javascript array using a manual index.
<script>
make[0] = "<%= con.getmake() %>" ;
document.write(make[0]);
make[1] = "<%= con.getmake() %>" ;
document.write(make[1]);
make[2] = "<%= con.getmake() %>" ;
document.write(make[2]);
make[3] = "<%= con.getmake() %>" ;
document.write(make[3]);
</script>
If I try and do the same with a for loop, It seems as though all the elements hold the same first variable retrieved from con.getmake, I am not getting the next variable from my java class.
<script>
for (var i= 0; i <= 2; i++)
make[i] = "<%= con.getmake() %>" ;
document.write(make);
</script>

Hi,
Java is parsed once on the server which creates a HTML page, then it is passed to the client's browser where the javascript is executed. So con.getmake() is only executed once in java. You've got to execute your loop in java not javascript :
<script>
<%
for (int i= 0; i <= 2; i++)
%>
document.write("<%= con.getmake() %>");
<%
%>
</script>
