I want to share how I did this  I spent the last few days rattling my head with how to pass a couple of parameters to the bootstrap modal dialog  After much head bashing  I came up with a rather simple way of doing this    Here is my modal code    lt div class  modal fade  id  editGroupNameModal  role  dialog  gt     lt div class  modal-dialog  gt       lt div class  modal-content  gt         lt div id  editGroupName  class  modal-header  gt Enter new name for group  lt  div gt           lt div class  modal-body  gt             lt    form tag    action   update group   port  portnum     do   gt             lt    text field tag   gid        type   hidden        gt             lt div class  input-group input-group-md  gt             lt span class  input-group-addon  style  font-size  16px  padding  3    gt Name lt  span gt             lt    text field tag   gname        placeholder   New name goes here   class   form-control   aria   describedby   basic-addon1        gt           lt  div gt           lt div class  modal-footer  gt             lt    submit tag  Submit     gt           lt  div gt           lt   end   gt         lt  div gt       lt  div gt     lt  div gt   lt  div gt    And here is the simple javascript to change the gid  and gname input values   function editGroupName id  name           input gid   val id          input gname form-control   val name         I just used the onclick event in a link                                                                                    amp  39  is single quote                                                                                        1    admin    lt a data-toggle  modal  data-target   editGroupNameModal  onclick  editGroupName  amp  39 1 amp  39    amp  39 admin amp  39    return false   href     gt edit lt  a gt    The onclick fires first  changing the value property of the input boxes  so when the dialog pops up  values are in place for the form to submit   I hope this helps someone someday   Cheers

You could do it like this    lt a class  btn btn-primary announce  data-toggle  modal  data-id  107   gt Announce lt  a gt    Then use jQuery to bind the click and send the Announce data-id as the value in the modals  cafeId     document  ready function           announce   click function       Click to only happen on announce links          cafeId   val   this  data  id              createFormId   modal  show
