Input type readonly

See attached html. Note type readonly on element subjo.

Not onChange function on element  subj.

None of this works. The element subjo accepts typing when the page is loaded. I'm using FireFox; I checked Error Console, no Javascript errors.

I also included css in case you need it.

What's wrong?

mainr3.css

hi, there is no input type 'readonly', but there is a html attribute 'readonly'.
you can set it in html:
<input type="text" readonly="readonly" .... />
or using javascript:
document.st.subjo.readonly = true;

type="readonly"??
It simply doesn't exists, so the browser use the default "input" type.
Use
<input type="text" readonly>

ps, for a modern html, use
<input type="text" name="subjo" readonly="readonly">

To all,

Thanks. I got it to partially work. Form field like this:

                        <td><input type="text" readonly name="subjo" size="30" class="pt8">&nbsp;<font size="-1">(Please enter a subject if "Other" is selected)</font></td>

But the onChange in the select element DOES NOT change the readonly attribute.

I tried it as follows and also with true & false; neither works.

      function chk_other() {
            if (document.st.subj.value == "Other") {
                  document.st.subjo.readonly = "";
            } else {
                  document.st.subjo.value = "";
                  document.st.subjo.readonly = "readonly";      
            }
            return true;
      }

try this:

      function chk_other() {
        if (document.st.subj.options[document.st.subj.selectedIndex].value != "Other") {
              document.st.subjo.readOnly = true;
        } else {
              document.st.subjo.value = "";
              document.st.subjo.readOnly = false;
        }
            return true;
      }
