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').getElementsByTagName('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

Those three lines of Struts code produce the output by themselves and can't be split up. Try something like this:

idoc += '<html:select property="ditta_id"><html

ptions collection="sel_ditta_list" labelProperty="label" property="value"/></html:select>';

The difference between <html:text> and <html:options> is that <html:options> generates multiple lines of HTML code, whereas <html:text> only generates one line. When Struts is generating these multiple lines of code separated by carriage returns, it doesn't know that you've included it in a JavaScript quoted string, so it doesn't know to enclose each line in quotes. That's why it's not working.

At the moment, I can't think of a way to make this work with Struts tags. Maybe someone else will post a possible solution. Unless someone does, I'd suggest using plain old HTML tags for your select/option tags rather than Struts tags.

Thanks for your reply but it didn't resolve the problem.
Seems that Struts html

ptions statement cut everything follows the tag and this is bad..

BTW: Error is still...

Error: unterminated string literal
File source:http://localhost:8180/nw/jsp/insertNewItemOperatore.jsp
Row: 119, Column: 10
Source code:
idoc += '<select name="ditta_id"><option value="1">1</option>

Luca,
Can you post the code you are using now?
