How to pass parameters to a modal?

Question

I want to pass the userName from a list of userNames a logged in user clicks on to twitter bootstrap modal. I am using grails with angularjs, where data is rendered via angularjs.

Configuration

My grails view page encouragement.gsp is

<div ng-controller="EncouragementController">
    <g:render template="encourage/encouragement_modal" />
    <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

My encourage/_encouragement_modal.gsp is

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{aModel.userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{aModel.userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

So, how can I pass userName to encouragementModal?

Answer 1

I tried as below.

I called ng-click to angularjs controller on Encourage button,

               <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" ng-click="setUsername({{user.userName}})" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

I set userName of encouragementModal from angularjs controller.

    /**
     * Encouragement controller for AngularJS
     * 
     * @param $scope
     * @param $http
     * @param encouragementService
     */
    function EncouragementController($scope, $http, encouragementService) {
      /**
       * set invoice number
       */
      $scope.setUsername = function (username) {
            $scope.userName = username;
      };
     }
    EncouragementController.$inject = [ '$scope', '$http', 'encouragementService' ];

I provided a place(userName) to get value from angularjs controller on encouragementModal.

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

It worked and I saluted myself.
