Invoking modal window in AngularJS Bootstrap UI using JavaScript

Question

Using the example mentioned here, how can I invoke the modal window using JavaScript instead of clicking a button?

I am new to AngularJS and tried searching the documentation here and here without luck.

Thanks

OK, so first of all the http://angular-ui.github.io/bootstrap/ has a <modal> directive and the $dialog service and both of those can be used to open modal windows.

The difference is that with the <modal> directive content of a modal is embedded in a hosting template (one that triggers modal window opening). The $dialog service is far more flexible and allow you to load modal's content from a separate file as well as trigger modal windows from any place in AngularJS code (this being a controller, a service or another directive).

Not sure what you mean exactly by "using JavaScript code" but assuming that you mean any place in AngularJS code the $dialog service is probably a way to go.

It is very easy to use and in its simplest form you could just write:

$dialog.dialog({}).open('modalContent.html');  

To illustrate that it can be really triggered by any JavaScript code here is a version that triggers modal with a timer, 3 seconds after a controller was instantiated:

function DialogDemoCtrl($scope, $timeout, $dialog){
  $timeout(function(){
    $dialog.dialog({}).open('modalContent.html');  
  }, 3000);  
}

This can be seen in action in this plunk: http://plnkr.co/edit/u9HHaRlHnko492WDtmRU?p=preview

Finally, here is the full reference documentation to the $dialog service described here: https://github.com/angular-ui/bootstrap/blob/master/src/dialog/README.md

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles

.modal {
    display: block;
}
.modal-body:before,
.modal-body:after {
    display: table;
    content: " ";
}
.modal-header:before,
.modal-header:after {
    display: table;
    content: " ";
}

(The last ones are necessary if you use custom directives) and encapsulate the html with

<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Modal title</h4>
    </div>
    <div class="modal-body">
      ...
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>
    </div>
  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

Open modal windows with passing data to dialog

In case if someone interests to pass data to dialog:

app.controller('ModalCtrl', function($scope,  $modal) {
      
      $scope.name = 'theNameHasBeenPassed';

      $scope.showModal = function() {
        
        $scope.opts = {
        backdrop: true,
        backdropClick: true,
        dialogFade: false,
        keyboard: true,
        templateUrl : 'modalContent.html',
        controller : ModalInstanceCtrl,
        resolve: {} // empty storage
          };
          
        
        $scope.opts.resolve.item = function() {
            return angular.copy(
                                {name: $scope.name}
                          ); // pass name to resolve storage
        }
        
          var modalInstance = $modal.open($scope.opts);
          
          modalInstance.result.then(function(){
            //on ok button press 
          },function(){
            //on cancel button press
            console.log("Modal Closed");
          });
      };                   
})

var ModalInstanceCtrl = function($scope, $modalInstance, $modal, item) {
    
     $scope.item = item;
    
      $scope.ok = function () {
        $modalInstance.close();
      };
      
      $scope.cancel = function () {
        $modalInstance.dismiss('cancel');
      };
}

Quick and Dirty Way!

It's not a good way, but for me it seems the most simplest.

Add an anchor tag which contains the modal data-target and data-toggle, have an id associated with it. (Can be added mostly anywhere in the html view)

<a href="" data-toggle="modal" data-target="#myModal" id="myModalShower"></a>

Now,

Inside the angular controller, from where you want to trigger the modal just use

angular.element('#myModalShower').trigger('click');

This will mimic a click to the button based on the angular code and the modal will appear.

The AngularJS Bootstrap website hasn't been updated with the latest documentation. About 3 months ago pkozlowski-opensource authored a change to separate out $modal from $dialog commit is below:

https://github.com/angular-ui/bootstrap/commit/d7a48523e437b0a94615350a59be1588dbdd86bd

In that commit he added new documentation for $modal, which can be found below:

https://github.com/angular-ui/bootstrap/blob/d7a48523e437b0a94615350a59be1588dbdd86bd/src/modal/docs/readme.md.

Hope this helps!

@AhmadAlfy yes, there are some options that allow you to control visual aspects of the modal. But more importantly it has many super-powers and allows you to treat $dialogs almost like AngularJS routes, pass data between the main window and the modal (and back) etc.

[Tim Gautier]

Yeah, the readme link is broken on the angular site also. I'd really like to read that file, but I can't figure out where it's hidden. :(

[Per Quested Aronsson]

Seems like $dialog has been replaced by a rewritten version of $modal: github.com/angular-ui/bootstrap/tree/…

[Mendhak]

$modal readme is here.

[keithl8041]

And here's some more info on the dialog re-write.

[FOR]

For those, like me, going back to Bootstrap 2.3.2 and Angular-UI-Bootstrap 0.5.0, I think the latest docs on the now defunct $dialog would be over here: github.com/angular-ui/bootstrap/commit/…

[jae]

the links for the items don't appear in your plunker - unfortunately i'm still pretty new w/ angular to determine why.

[Anton Manevskiy]

Awesome. But why you in resolve pass empty storage and then add $scope.opts.resolve.item = function() ?

[Maxim Shoustin]

just for code read. You can write for sure, resolve:{ item: function(){return ..} }

[Rizwan Patel]

i wanted to include (modal) html element in same page rather then creating external html file (externalTemplate.html'). any suggestion !

[Saiyaff Farouk]

Is this actually a good practice? Is this recommended or discouraged? Using this way, how it can affect the performance? Of course writing a line of code is easier than writing a whole function But, Still

[Gagandeep Singh]

Like I said "It's not a good way..." because it's inconsistent with the design paradigm of angular. I think it's discouraged because of that reason. For the performance part - I don't think it should cause any difference. But, again if I was the expert, I shouldn't have followed this shortcut approach. It's just a quick and dirty way to get things done. :) Do tell me if you find something regarding this.

[VictorySaber]

I'm new to Angular, and to get my modal up-and-running this worked very well indeed. I can come back and do it properly once I've learnt how (and this milestone deadline has passed)
