在JavaScript和嵌入式Java之间传递变量

Question

I'm running a web service and calling a method by embedding the java inside the script:

    <script type="text/javascript">
        function getSS(){
<%-- start web service invocation --%>

var x = <%
try {
    org.me.testbilling.TestBillingWS_Service service = new
    org.me.testbilling.TestBillingWS_Service();
    org.me.testbilling.TestBillingWS port = service.getTestBillingWSPort();

    java.lang.String name = "Mike" ;

    java.lang.String result = port.getSS(name);
    out.println(result);
} catch (Exception ex) {
   out.println(ex);
}
%>
<%-- end web service invocation --%>

    alert(x);
        }
    </script>

The issue is that I want this line:

java.lang.String name = "Mike";

To be dynamic, so that it can pull a variable from text the user entered, or a selection like this:

<select id="getName" onchange="getSS($('#getName').find(":selected").text())">
<option>Mike</option>
<option>John</option>
<option>Patty</option>
<option>Stephanie</option>
</select>

So what I need is either a better way to make that call, or a way to pass the variable dynamically into that script. Any suggestions?

JavaScript is on client machine, but your java is on server.

If you want to send data from client to server, you need to use jQuery.ajax to send.
