javascript - Modal Bootstrap User Confirmation -


how can create jquery function waits till user confirms whether or not wants delete data.

how can achieve this:

function userconfirmation() {   showmodal();    //"global" delete confirmation bootstrap modal   //now wait till user decides whether or not wants    //delete data(button events or on modal hide).   //on user reply:   if(userreplied == 'delete')   {}   else   {}  }

edit:

this html code modal in layout. modaldelete called through showmodal() function whenever need be.

<!-- delete data confirmation modal -->     <div class="modal fade" id="modaldelete" role="dialog" data-backdrop="static" data-keyboard="false">         <div class="modal-dialog modal-sm">              <!-- modal content-->             <div class="modal-content">                 <div class="modal-header">                     <button type="button" class="close" id="btn-cancel" data-dismiss="modal">&times;</button>                     <h4 class="modal-title">confirm delete</h4>                 </div>                 <div class="modal-body">                 </div>                 <div class="modal-footer">                     <button type="button" class="btn btn-success" id="btn-cancel" data-dismiss="modal">cancel</button>                     <button type="button" class="btn btn-danger btn-delete" id="btn-delete" data-dismiss="modal">delete</button>                 </div>             </div>          </div>     </div>

the function userconfirmation listens modal events after calling showmodal() , on button press or modal hide proceed depending on user's choice.

i think can achieved through promise or deffered action.

ok here how solved question using promise jquery deferred:

  1. this function listens till user clicks on button in #modaldelete , returns id of button clicked.

    function modaloptionchoosen() {  var deferred = $.deferred();  $('#modaldelete button').on('click', function (e) {     var $target = $(e.target); // clicked button element     $(this).closest('.modal').on('hidden.bs.modal', function () {         //console.log($target); // logged if clicked button closed modal         var result = $target.attr('id');         deferred.resolve(result);     }); });  return deferred.promise(); };

  2. while function waits promise above modaloptionchoosen() returned.

    function showmodalwaitforresult () {     showmodal();      var promise = modaloptionchoosen();     promise.done(function (result) {         console.log(result); // log user selected value     }); });

now can reference modaloptionchoosen function anywhere if need be.
