Question about struts inside javascript variable

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

My (working) code is:

idoc="";
/* var cols =
parent.document.getElementById('rowA').getElements ByTagName('THEAD')
[0].getElementsByTagName('TH'); */
var idoc='<html:form styleId="InsertNewItem" action="/nw/
insertnewitem.do?target='+parent.newPop.action+'"> ';
idoc+='<TABLE><TBODY>';
var hiddenForm = getParentObj('hidden_data_form');
var cols = hiddenForm.getElementsByTagName('INPUT');
var test;
test="cippa";
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>";
}

}

idoc+='</TBODY></TABLE>';
idoc+='</html:form>';
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 ptions collection="sel_ditta_list"
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?

Thanks in advance
Luca

Did you try adding an extra quote? does it work?

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

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.

I'm finding it hard to follow exactly what's happening here, but the
last comment here is very important. Emitting tags like "<html:text>"
in javascript will have absolutely no useful impact. Struts tags (and
other tag libraries like it) are processed on the server side, when
the JSP page is compiled into a Java servlet class. These tags are not
interpreted by the browser in any way.
