    selectbox

    Hello,

    When I have the next example, it shows me if item 2 is selected YES or NO

    <html>
    <script language="javas cript">
    function doit()
    {
    alert(document. forms["tst_frm"].elements["listbox"].options[2].selected)
    }
    </script>

    <body>
    <FORM id=tst_frm name=tst_frm action=javascri pt:doit() method=post>
    <SELECT multiple size=5 name=listbox>
    <OPTION value=1>1</OPTION>
    <OPTION value=2>2</OPTION>2
    <oPTION value=3>3</OPTION>
    <OPTION value=4>4</OPTION>
    <OPTION value=5>5</OPTION>
    </SELECT>

    <INPUT type=submit value="DOit" name=submit>

    </FORM>
    </body>
    </html>

    When I change then name field to a name with brackets (array)

    <SELECT multiple size=5 name=listbox[]> It won't work. How can the
    javascript work with the brackets in the name fields

    Many thanks in advance

    Richard

      Your HTML syntax and JavaScript is invalid, wrong or both. Rather than
      rewrite the whole thing, why don't you tell us what you want the JavaScript
      to do and I or someone can show you how it is done. Are you just wanting to
      know which item or items are selected?

          Wat is I want to do is create an listbox where you can select multiple
          items. The selection must be handedover to PHP as an array. The PHP code is
          running fine.
          Before the form is submitted, I have to check releatiosn to other field in
          the form. To simplify it, I made small example which has the same behaviour.

                  PHP: PHP and HTML - Manual

                  You should also get in the habit of quoting all your HTML attributes,
                  matching case and so on...run it through a validator.
