How to ensure a <select> form field is submitted when it is disabled?

I have a

select
form field that I want to mark as "readonly", as in the user cannot modify the value, but the value is still submitted with the form. Using the
disabled
attribute prevents the user from changing the value, but does not submit the value with the form.

The
readonly
attribute is only available for
input
and
textarea
fields, but that's basically what I want. Is there any way to get that working?

Two possibilities I'm considering include:


  • Instead of disabling the
    select
    , disable all of the
    option
    s and use CSS to gray out the select so it looks like its disabled.

  • Add a click event handler to the submit button so that it enables all of the disabled dropdown menus before submitting the form.


Answer
<select disabled="disabled">
    ....
</select>
<input type="hidden" name="select_name" value="selected value" />

Where select_name is the name that you would normally give the <select>.

Another option.

<select name="myselect" disabled="disabled">
    <option value="myselectedvalue" selected="selected">My Value</option>
    ....
</select>
<input type="hidden" name="myselect" value="myselectedvalue" />

Now with this one, I have noticed that depending on what webserver you are using, you may have to put the hidden input either before, or after the <select>.

If my memory serves me correctly, with IIS, you put it before, with Apache you put it after. As always, testing is key.
