Re: Problem with getting an array value

    You can get the value in the variable "valInSelect".

 

    What you have to do is ?

        declare a form variable as hidden say "listedValues" and then assign the "valInSelect" to "listedValues".

    Now in your servlet you can get the value as

 

        String value = request.getParameter("listedValues"); 
        System.out.println("value = "+ value);

The code snippet is attached below

<script language="javascript">
     function listValue(){
        valInSelect = "";
        len = document.Sort.selectTest.options.length;
      
        for (i = 0;i < len; i++) {
            if ( document.Sort.selectTest.options[i].selected) {
                valInSelect = valInSelect + "," +
                              document.Sort.selectTest.options[i].value;
            }
        }
        document.Sort.listedValues.values = valInSelect;
        alert ("The Val In listedValuesSelect is" +  document.Sort.listedValues.values);

 

    }
</script>

 

 <form name="Sort">
    <input type="hidden" name="listedValues">
    <select name="selectTest" size=2 width=200 multiple>
        <option value="Servlet">Servlet
        <option value="JSP">JSP
        <option value="J2EE">J2EE
    </select>

 

     <input type="submit" name="Add" value="ADD"
     > </form>
