    question about readonly property

    HI, all
    I found the return value from obj.readOnly is always the original vaule in
    HTML setting, even after doing obj.readOnly=tr ue/false. How can I get the
    real time value set by javascript?

      The new value is submitted regardless of the readonly setting.
      What makes you think that it isn't?
      If you're submitting to the same page, you won't see the new
      value in the form field.

          For example ...

          <TD>
          <INPUT TYPE="text" id="itemdesc" READONLY class=scFieldRe cList
          name="page1"></TD>
          <TD>
          .....
          itemdesc.readOn ly=false;
          alert(itemdesc. readOnly);
          .....
          I mean the alert always show "true" rather than "false".

              This alerts false in Netscape 7.1 and IE 6:

              <html>
              <body>
              <form>
              <INPUT TYPE="text"
              id="itemdesc"
              READONLY
              class=scFieldRe cList
              value="initial value"
              name="page1">
              </form>
              <script>
              document.getEle mentById("itemd esc").readOnly= false;
              document.getEle mentById("itemd esc").value="ne w value";
              alert(document. getElementById( "itemdesc").rea dOnly);
              </script>
              </body>
              </html>

                  Thank's Lee
                  Yes, it should be exactly as what you show on your sample. I ve got to
                  check my program. My example is just a short cut from my real one. Thank you
                  very much!
