Hi, actually i'm using a struts + javascript to create HTML code that
i use inside a popup window...

My (working) code is:

/* var cols =
[0].getElementsByTagName('TH'); */
var idoc='<html:form styleId="InsertNewItem" action="/nw/'+parent.newPop.action+'">';
var hiddenForm = getParentObj('hidden_data_form');
var cols = hiddenForm.getElementsByTagName('INPUT');
var test;
for(k = 0; k < cols.length; k++) {
if(cols[k].id.substring(0,3) == "hh_")

idoc += "<TR><TD>";
idoc += cols[k].id.substring(3);
idoc += "</TD><TD>";
idoc += '<html:text property="'+cols[k].id+'" value=""/>';
idoc += "</TD></TR>";


var towr = document.getElementById("subwin_body");
towr.innerHTML = idoc;

The problem is when i try to add a <html:select> to the code, more
precisely i added just before the end of the table these lines:

idoc += "<TR><TD>Ditta:";
idoc += "</TD><TD>";
idoc += '<html:select property="ditta_id">';
idoc += '<html :o ptions collection="sel_ditta_list"

Was this copied literally? That extra space before the colon and after the
'o' might be trouble.

labelProperty="label" property="value"/>';

idoc += '</html:select>';
idoc += "</TD></TR>";

... but i cannot get it to work because struts seems to make some
mistake with quotes and in javascript console window i get this error:

Error: unterminated string literal
File source: http://localhost:8180/nw/jsp/insertNewItemOperatore.jsp
Row: 121, Column: 10
Source Code:
idoc += '<option value="1">1</option>

(note the missing ending single-quote)

I can't understand why because with <html:text> field the same "trick"
works fine... any ideas?

First: PLEASE indent your code (using spaces) for readability!

I am surprised that a client-side insertion of JSP tags would work, since JSP
tags are parsed server side.
