Problem with Html field naming and java script

Question

Java Script which references html fields uses the
notation "document.form[0].field". JATO generates field names which
include the page (view bean). A dot is placed between viewbean name and
field name(viewbean.field). However "document.form[0].viewbean.field"
doesn't work as a reference. I'm not a java script person. Am I
missing something?

Answer 1

that's correct. You can use the below code for AJAX request.
<script type="text/javascript">
var httpObject = getHTTPObject();
//create XMLHttpRequest object
function getHTTPObject() {     
     var xmlhttp;
     if (window.XMLHttpRequest) // if Mozilla, Safari etc
          xmlhttp = new XMLHttpRequest();
     else if (window.ActiveXObject){ // if IE
          try {
               xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
          catch ( e ){
               try{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
               catch ( e ){}
     return xmlhttp;
//define the function to send the request
function sendRequest(){
    var currDesc = document.getElementById("description").value;
    var URL =  "manageMaintAction.do"; //action mapping in your struts-config
    var queryString = "currDesc="+escape(currDesc); //get the currDesc value in your action class like request.getParameter("currDesc")
    httpObject.open( "Post", URL, true );
    httpObject.onreadystatechange = cbFn;
    httpObject.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
    httpObject.send(queryString);
//callback fn
function cbFn() {
    if (httpObject.readyState == 4)
         if (httpObject.status == 200)
          var result = httpObject.responseText;
          alert(result);
</script>
