AngularJS.调用 angular-ui 模态时清除 $timeout [英] AngularJS. Clear $timeout when invoking angular-ui modal

问题描述

我在模态控制器中有几个 $timeout 表达式

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);
        })()
    }
})

我需要在调用模态时清除所有计时器:

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
        });
    } })

我该怎么做?

PS 抱歉代码格式错误.我不知道为什么，但我无法更好地格式化它.我在这里复制了代码:

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

推荐答案

$timeout 服务返回一个 Promise 对象，可用于取消超时.

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);

要取消所有挂起的超时，您需要维护一个承诺列表，并在打开模态时取消完整列表.

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