Re: Simulating Client field prompting -- follow up

[Susan Bradeen <Su...@softlanding.com>]

Following up with my solution, in case others have a similar question, and 
thanks again to those who offered ideas. I ended up using a separate 
selection window, and compromised on some JavaScript usage. Struts actions 
open the new window and populate the selection list. JavaScript is used 
only to pass the field values back to the original form and "auto" close 
the selection window. Without access to JavaScript, one could still look 
up the desired information, but must manually type in the field values on 
the form and close the selection window.

In my form JSP, I open the selector (JSP) window using a link next to each 
field: 

<snip>
  <html:link page="/promptselector.do?field=person" target="_blank">Select Person</html:link>
</snip>

In my selector JSP:

<snip>
<script language="JavaScript">
function promptPerson(id, first, last) {
        window.opener.document.forms[0].person.value = id;
        window.opener.document.forms[0].personName.value = first+" "+last;
        self.close();
}
</script>
 </snip>

<snip>
<logic:iterate name="promptform" property="persons" id="person">
<tr align="left">
  <td><bean:write name="person" property="personID"/></td>
  <td><bean:write name="person" property="firstName"/></td>
  <td><bean:write name="person" property="lastName"/></td>
  <td><a href="javascript:promptPerson(
      '<bean:write name="person" property="personID"/>', 
      '<bean:write name="person" property="firstName"/>', 
      '<bean:write name="person" property="lastName"/>')" >Select</a>
  </td>
</tr>
</logic:iterate>
</snip>
