AngularJS. Clear $timeout when invoking angular-ui modal


I have several $timeout expressions in Modal controller

App.controller('ModalCtrl', function ($scope, $timeout) {
    for (var i = 0; i < 10; i++) {
        (function () {
            var timer = $timeout(function () {
                console.log('timer')
            }, 1000);
        })()
    }
})

I need to clear all the timers when invoking the modal:

App.controller('MainCtrl', function ($scope, $modal, $timeout) {
    $scope.showMap = function () {
        var modal = $modal.open({
            templateUrl: 'modalap.html',
            controller: 'modalCtrl',
        })

        modal.result.then(function () { //fires when modal is resolving
        }, function () { //fires when modal is invoking
        });
    } })

How can I do that?

PS Sorry for bad code formatting. I don't know why but I cant format it better. I duplicated code here:


Solution

  • The $timeout service returns a Promise object which can be used to cancel the timeout.

    // Start a timeout
    var promise = $timeout(function() {}, 1000);
    
    // Stop the pending timeout
    $timeout.cancel(promise);
    

    To cancel all pending timeouts, you need to maintain a list of promises and cancel the complete list when you open the modal.
