Does your input field have a name as well as an id?

Struts does some special magic to pull request parameters into its Form
classes. If you don't use its html: tag lib than you might need to make
explicit request.getParameter() calls in the Action class for those parameters.

Using Ajax you will be passing all the request parameters through GET
and the there is no form.submit() happening. This may be one of the
reasons. In that case only way to send these parameters is to build
the URL string with the request parameters. Look at the code below to
build your URL.

function retrieveURL(url,nameOfFormToPost) {

 //convert the url to a string
 url=url+getFormAsString(nameOfFormToPost);

 //Do the AJAX call
 if (window.XMLHttpRequest) {

   // Non-IE browsers
   req = new XMLHttpRequest();
   req.onreadystatechange = processStateChange;
   try {
         req.open("GET", url, true);
   } catch (e) {
     alert("Server Communication Problem\n"+e);
   }
   req.send(null);
 } else if (window.ActiveXObject) {
   // IE

   req = new ActiveXObject("Microsoft.XMLHTTP");
   if (req) {
     req.onreadystatechange=processStateChange;
     req.open("GET", url, true);
     req.send();
   }
 }
}

getFormAsString() is a "private" method used by the retrieveURL()
method. This will get all the form Elements and appends to the URL

function getFormAsString(formName){

 //Setup the return String
 returnString ="";

 //Get the form values
 formElements=document.forms[formName].elements;

 //loop through the array, building up the url
 //in the format '/strutsaction.do&name=value'

 for(var i=formElements.length-1;i>=0; --i ){
       //we escape (encode) each value
       returnString+="&"
       +escape(formElements[i].name)+"="
       +escape(formElements[i].value);
}

//return the values
return returnString;
}
