How to represent a Java array in javascript of a Java Web Project?

Question

Assume I have following code in a jsp file in JavaWeb:

<%
String myList = new String[10];
for(int i=0;i<10;i++){
    myList[i] = String.valueOf(i);
}
%>

Now I want to get the value of the elements of myList in a loop of javascript: Are the following ways are correct?

<script type="text/javascript">
var arr = new Array(10);
for(var i=0;i<10;i++){
    arr[i] = "<%=myList[i]%>"
}
<script>

If not, how could I reach my purpose?

Well, if it works then it's probably correct. Otherwise no. Does it work? — RaminS

I haven't test it yet. But commonly it is not right because the value i is the value of javascript and it can not be used in java code in <% %> — Litchy

No, this isn't correct. Because the jsp i will never change.
