ASP dataset - load into Javascript Array

I have a simple ASP recordset being returned that I create a table from with a checkbox in the final column.

At the same time I wish to store the City_ID and City_Name values into a multi dimensional array in Javascript.

Once the values are into the array I will be looking at a method of searching that array for City_Name.  So eg if I typed in Paris - as long as the item was in the array - I would get returned the ID for Paris (which I would then automatically check the checkbox for that ID)

So in short - I need to add the Recordset items of City_ID and City_Name into a 2 dimensional array.
Then I need a method or example of how I would search for a string in that array based on City_Name that would return the corresponding City ID.

I can do this on a VB side easily but Javascript is not really my key area so your help is appreciated
<table class="data" id="tblTrips" sort="yes">
              	<tr>
                    <th>ID</th><th>Location</th><th>Select</th>
                </tr>
                <% 		
                    Do While Not RsX.EOF 
                %>
                
                <tr>
                  <td width="75"><% Response.Write RsX("City_ID") %> </td>
                    <td><% Response.Write RsX("City_Name") %> </td>            
                    <td align="center">
                      <input name="<% Response.Write RsX("City_Name") %>" type="checkbox" id="<% Response.Write "cbx_" & RsX("City_ID")%>" value="<% Response.Write RsX("City_ID") %>" onclick="javascript:loopForm();" />
                    </td>
               </tr>
                   
               <% 
                    RsX.MoveNext		
                    Loop
               %>
                                        
              </table>

Maybe this little example will help you. Never used it.
<html><head><title>Test</title>
</head><body>
<script type="text/javascript">
var Customer = new Array();
 
Customer[0] = new Object();
Customer[0]["Lastname"] = "Miller";
Customer[0]["Firstname"] = "Jack";
Customer[0]["City"] = "New York City";
 
Customer[1] = new Object();
Customer[1]["Lastname"] = "Schneider";
Customer[1]["Firstname"] = "Bob";
Customer[1]["City"] = "Dallas";
 
for (var i = 0; i < Customer.length; i++) {
  document.write("<dl><dt>Customer " + (i + 1) + "<\/dt>");
  for (var CustomerProperty in Customer[i])
    document.write("<dd>" + CustomerProperty + ": " + Customer[i][CustomerProperty] + "<\/dd>");
  document.write("<\/dl>");
}
</script>
</body></html>

unfortunately that doesn't really cover how I add the array values from the asp.

As for my example:
<script type="text/javascript">
var Customer = new Array();
<%
i = 0
Do While Not objRs.EOF
  %>
  Customer[<% = i %>] = new Object();
  Customer[<% = i %>]["Lastname"] = <% = objRs("Lastname") %>;
  Customer[<% = i %>]["Firstname"] = <% = objRs("Firstname") %>;
  Customer[<% = i %>]["City"] = <% = objRs("City") %>;
  <%
  objRs.MoveNext
  i = i + 1
 
Loop
%>
</script>

Used this as the basis and developed what you put from there.  Cheers
