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

Question

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 options 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

Based on the solution of the Jordan  I created a function that automatically creates a hidden input with the same name and same value of the select you want to become invalid  The first parameter can be an id or a jquery element  the second is a Boolean optional parameter where  true  disables and  false  enables the input  If omitted  the second parameter switches the select between  enabled  and  disabled    function changeSelectUserManipulation obj  disable       var  obj     typeof obj      string           obj    obj      disable   disable    disable     obj is   disabled         if disable            obj prop  disabled   true               after   lt input type  hidden  id  select user manipulation hidden    obj attr  id      name     obj attr  name      value     obj val      gt          else           obj prop  disabled   false               next   select user manipulation hidden    obj attr  id    remove             changeSelectUserManipulation  select id

I was faced with a slightly different scenario  in that I only wanted to not allow the user to change the selected value based on an earlier selectbox  What I ended up doing was just disabling all the other non-selected options in the selectbox using     toSelect  find   not  selected    prop  disabled  true

lt select disabled  disabled  gt            lt  select gt   lt input type  hidden  name  select name  value  selected value    gt    Where select name is the name that you would normally give the  lt select gt    Another option    lt select name  myselect  disabled  disabled  gt       lt option value  myselectedvalue  selected  selected  gt My Value lt  option gt            lt  select gt   lt input type  hidden  name  myselect  value  myselectedvalue    gt    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  lt select gt    If my memory serves me correctly  with IIS  you put it before  with Apache you put it after  As always  testing is key

Another option is to use the readonly attribute    lt select readonly  readonly  gt            lt  select gt    With readonly the value is still submitted  the input field is grayed out and the user cannot edit it   Edit   Quoted from http   www w3 org TR html401 interact forms html adef-readonly     Read-only elements receive focus but cannot be modified by the user  Read-only elements are included in tabbing navigation  Read-only elements may be successful    When it says the element may be succesful  it means it may be submitted  as stated here  http   www w3 org TR html401 interact forms html successful-controls

Or use some JavaScript to change the name of the select and set it to disabled  This way the select is still submitted  but using a name you aren t checking

Same solution suggested by Tres without using jQuery   lt form onsubmit  document getElementById  mysel   disabled   false   action       method  GET  gt       lt select id  mysel  disabled  disabled  gt      lt  select gt       lt input name  submit  id  submit  type  submit  value  SEND FORM  gt   lt  form gt    This might help someone understand more  but obviously is less flexible than the jQuery one

I whipped up a quick  Jquery only  plugin  that saves the value in a data field while an input is disabled  This just means as long as the field is being disabled programmaticly through jquery using  prop   or  attr      then accessing the value by  val     serialize   or  serializeArra   will always return the value even if disabled     Shameless plug  https   github com Jezternz jq-disabled-inputs

The easiest way i found was to create a tiny javascript function tied to your form    function enablePath         document getElementById  select name   disabled          and you call it in your form here      lt form action  act php  method  POST  name  form name  onSubmit  enablePath     gt    Or you can call it in the function you use to check your form
