Try this      button eq 0       dialog id   dialog buttons  button  disable

If you really want to disable a button  I found that you also need to call the  unbind   method on it  Otherwise the button may still be active  and a double-click could lead to multiple form submissions  The following code works for me   button     this  parent   find  button contains  OK      button unbind    button addClass  ui-state-disabled

In the legacy jQuery UI  version 1 7 3  I was able to simply use      ui-dialog-buttonpane button   0  disabled true    to just disable the button on the DOM element itself   Now that we ve upgraded to the newer jQuery UI  version 1 8 7  that method no longer works in Firefox  but I can simply call the jquery UI button specific disable and enable functions on the button jquery objects       ui-dialog-buttonpane button   eq 0  button  disable

Calling  attr  disabled   true  of course works  but using jQuery you d like do it in more  sugar  way  so I ve written simple extension    function            fn disable   function isDisabled        var val   isDisabled      if  isDisabled     undefined          val   true      this attr  disabled   val            fn enable   function isEnabled        var val    isEnabled      if  isEnabled     undefined          val   false      this attr  disabled   val            jQuery      Now you have functions enable   and disable    so you can do your job that way       continueButton   disable      Which is same as      continueButton   disable true     and      continueButton   enable false

You are all over complicating a simple task  the jQueryUI dialog has two ways to set buttons for a reason   If you only need to set the click handler for each button  use the option that takes an Object argument  For disabling buttons and provide other attributes  use the option that takes an Array argument   The following example will disable a button  and update its state correctly by applying all of the jQueryUI CSS classes and attributes    Step 1 - Create your dialog with an Array of buttons      Create a dialog with two buttons   Done  and  Cancel       selector   dialog   buttons                  id   done          text   Done           click  function                                id   cancel          text   Cancel           click  function                         Step 2 - Enable disable the Done button after the dialog is created        Get the dialog buttons  var dialogButtons        selector    dialog  option    buttons        Find and disable the  Done  button    each buttons  function  buttonIndex  button        if  button id      done             button disabled   true               Update the dialog buttons      selector   dialog  option    buttons   dialogButtons

I found a workaround that may apply to people trying to do something similar  Instead of disabling the button I put a simple if statement in the function to check if the checkbox was checked   If it wasn t  it displayed a simple message saying the box had to be checked before submission   For example       confirmation-dialog   dialog       modal  true      autoOpen  false      width  600      overlay            backgroundColor    000           opacity  0 5            close  function                input type  submit            val  Record Reading          attr  disabled   false              buttons             Confirm Reading   function                 if     check-box   attr  checked                       this  dialog  close                      form                    addClass  confirmed                    submit                              else                       please-check   show  slide                                        Anyway  I hope that helps someone

Here s an example that I just implemented using the Array method of assigning buttons  which then allows me to use id selectors later on - just as the accepted answer stated originally - to enable disable buttons and even show hide them completely as I m doing        dialog-form    dialog   autoOpen  true  height  500  width  450  modal  true  buttons          id   submit btn       text   Make Apointment       click  function                do ajax                              id   cancel btn       text   Cancel       click  function               this   dialog   close                    id   ok btn       text   OK       click  function               this  dialog  close               disabled   disabled      close  function         allFields val       removeClass   ui-state-error             After successfully submitting  I disable and hide two of the buttons and enable the OK button that was disabled by default       submit btn   cancel btn   attr  disabled   disabled   addClass  ui-state-disabled   hide        ok btn   attr  disabled      removeClass  ui-state-disabled   show      Hope this helps

I created a function similar to what Nick did  but my method would not require setting the dialogClass and you will be able to get the buttons of a specific dialog via the id  if more than one exists in your application   function getDialogButton  dialog id  button name        var target       dialog id      var buttons     target  parent   find  button        for   var i 0  i lt buttons length    i             var jButton      buttons i             if   jButton text      button name                   return jButton                      return null       So if you created the dialog like so     function             myDialogBox   dialog          bgiframe  true  height   auto   width  700  modal  true        buttons             Add to request list   function                                            this  dialog  close                                            form   submit                                               Cancel   function                              this  dialog  close                                      You can get the buttons by doing the following   var addToRequestListBtn   getDialogButton  myDialogBox   Add to request list    var cancelBtn             getDialogButton  myDialogBox   Cancel      To disable   addToRequestListBtn attr  disabled   true  addClass   ui-state-disabled              cancelBtn attr  disabled   true  addClass   ui-state-disabled      To enable   addToRequestListBtn attr  disabled   false  removeClass   ui-state-disabled              cancelBtn attr  disabled   false  removeClass   ui-state-disabled

Unfortunately no solutions from given here worked for several dialogs on the page   Also the problem was that original dialog  doesn t contain button pane in itself  but is a sibling of it   So I came up with selecting by dialog ID like that           var getFirstDialogButton   function  dialogSelector                return     ui-dialog-buttonpane button first                         dialogSelector  parent   0                                  my dialog   dialog               open  function event  ui                    getFirstDialogButton   my dialog                     addClass  ui-state-disabled   attr  disabled    disabled                           and then the same getFirstDialogButton   function could be later used to enable button  e g  after successful validation   Hope it can help someone
