Javascript - Java list menu

P: 1
Hi,

I am retrieving a selected item from a list/menu component on an
HTML page. The said value is passed as a parameter to a method
initiated through <jsp:useBean.


I am aware that when the user selects an item from the list/menu an
onChange event is triggered. I have handled this event by a javascript
function.


The table is populated according to the selected item, and therefore I have used the following syntax in order to populate an already defined table 'tblResults': var x=document.getElementById('tblResults').insertRow( );

Before populating each row I need to retrieve the data using the method <% outResult = result.getResult(xxx);%>, where results is the object declared by the <jsp:useBean. The xxx refers to a variable pointing to the HTML list/menu. I am able to call this method through the use of scriptlets. When I pass a value instead of xxx the process works correctly and the data is loaded into the database, however I cannot find a way of how I can pass the variable. I attempted to use

I would appreciate your kind help

Happy Christmas and thanks

Have a input type hidden in ur html and set the value when the select is changed. You can access that input value using request.getAttribute("hidden field name ")

Thanks and Regards

You're mixing up Java/JSP and JavaScript. One is server-side and one is client-side. If you want to use both without a page reload, use Ajax.
