Angular UI Bootstrap Modal - how to prevent multiple modals opening

Question

I've implemented the modal directive, and set the $modal.open option backdrop to false. However, now I can trigger multiple modals to open. Is there a way to prevent the trigger button from firing once one modal is open?

var accountSummaryCtrl = function ($scope, $modal, $log) {

    $scope.open = function () {

        var modalInstance = $modal.open({
            templateUrl: '/Apps/generic/modal/Templates/AccountSummary.html',
            controller: ModalInstanceCtrl,
            backdrop: false
        });

        modalInstance.result.then(function (selectedItem) {
            $scope.selected = selectedItem;
        }, function () {
            $log.info('Modal dismissed at: ' + new Date());
        });
    };
};

Thanks

Use a boolean flag to avoid it:

var accountSummaryCtrl = function ($scope, $modal, $log) {

    var opened = false;

    $scope.open = function () {

        if (opened) return;

        var modalInstance = $modal.open({
            templateUrl: '/Apps/generic/modal/Templates/AccountSummary.html',
            controller: ModalInstanceCtrl,
            backdrop: false
        });

        opened = true;

        modalInstance.result.then(function (selectedItem) {
            $scope.selected = selectedItem;
            opened = false;
        }, function () {
            $log.info('Modal dismissed at: ' + new Date());
            opened = false;
        });
    };
};
