java script question

[Jane . Muse]

This isn't exactly a struts question, but I've seen some similar questions
posed in this user list related to java script. What I'm trying to do is
display values in a drop down list based on a value selected from another
drop down. Depending upon what is selected, I will get the value selected
from the drop down, and dynamically populate the second drop down. I am
using the onchange java script attribute on my struts html tag that fires
an event when I select an item from the first drop down. I need to take the
value selected, use it as a key, and get data from a preloaded array that
has the data that I need for the second drop down. I know from reading
through the struts user list that I need to load the array in the java
script function to be able to get data from from it. The question is, how
do I load this array in my java script function?

Can the allMethodsTypes array get loaded in the java script function by
referencing it as a JSP expression?

Thanks,
Jane

Here's the code

     String [][] allMethodsTypes;

          try {
               allMethodsTypes  = new String [methodNamesList.size()][];
               for (int methodindex = 0; methodindex < methodNamesList.size
(); methodindex++) {
                    String method
= (String)methodNamesList.get(methodindex);
                    methTypes = bomb.getListOfMthdTypeDef(method);
                    allMethodsTypes[methodindex] = new
String[methTypes.size() + 1];
                    allMethodsTypes[methodindex][0] = new String(method);
                    for (int typeindex = 0; typeindex < methTypes.size();
typeindex++) {
                         String type = (String)methTypes.get(typeindex);
                         allMethodsTypes[methodindex][typeindex + 1] = new
String(type);
                    }
               }
          }
          catch (Exception e) {
               System.out.println("Exception building allMethodsTypes
array" + e);
             }
     }
%>

<select name="methodNames" size="1" onchange="selectMethodTypes(this.form)"

<script language="JavaScript1.1">
     function selectMethodTypes(f, test)
     {
     var i;
     var x;
     if(!f) {
         return;
     }

     var l = f.methodNames.length;
     for (i=0; i<f.methodNames.length; i++) {
        if (f.methodNames[i].selected) {
          var s = f.methodNames[i].value;
          alert(s);
          <%
          for (x=0; x<allMethodsTypes[i][].length; x++) {
          %>
              if (s = allMethodsTypes[i][x]);
               f.methodTypes[x].value = allMethodsTypes[i][x];
              }
          }
        }
     }
     }
</script>
