There is no direct conversion between Java and Javascript objects (I hear tell
of some libraries to do this though...)
What you'll need to do otherwise is iterate over the List and construct
Javascript from it, something like this:
<html><head><title>test</title><script>
myArray = new Array();
<%
int i = 0;
for (Iterator it = myForm.getTheList().iterator(); it.hasNext(); ) {
%>
myArray[<%=i%>] = "<%=it.next()%>";
%>
i++;
}
%>
</script><head><body>
You now have an array named myArray in Javascript, populated with the data from
the list
</body></html>
You can of course do this with taglibs, and in some ways it's better, but the
underlying theory is the same either way. You'll wind up with something like
this rendered to the browser:
<html><head><title>test</title><script>
myArray = new Array();
myArray[0] = "value1";
myArray[1] = "value2";
myArray[2] = "value3";
</script><head><body>
You now have an array named myArray in Javascript, populated with the data from
the list
</body></html>
That's it.
