Dropdown populates other fields

[Rob Lynn]

Hi. I am have a dropdown 'select' that should populate several other fields on the page depending on which item was selected. My select objects come from a java object (I'm using jsps and jstl to iterate through the object list and populate the options.) Other fields in the java object would be the (default) values for the fields that are populated based on the selection. My intention is to populate arrays using javascript with the values contained in the object for each field and then use the selected index to access them and set the form values. My problem is how to get the extra fields out of the java object and into the javascript array. Here's where I'd like to do it:

        <select name="obj" onChange="populateForm()">
          <c:forEach items="${docObjects}" var="item" varStatus="status">
            <option value="<c :-o	 ut value="${item.id}"/>"><c :-o	 ut value="${item.name}"/></option>
 
          [I] //call function here to set the other values into an array:
            set_array(status.count, item.desc, item.width, item.height)[/I]
 
          </c:forEach>
        </select>
 
  

How can I accomplish this? Thanks!

I've done it two ways:

1 - create javascript arrays containing all possible values from within the java code

2 - use an ajax request to get new values.

Honestly, I've switched from 1 to 2.

Also honesly, I'm more a java guy that an html/javascript guy
