Javascript AngularJS中的自动刷新

在下面的代码中，在autorefresh上，计时器在发送所有查询时启动，但我希望计时器在所有ajax查询完成时启动。 我该怎么做呢

    $scope.autoRefresh = function(){
    $scope.running = !$scope.running;
    $scope.timeoutsec = 10;
    if($scope.running)
    {
        $scope.timer = setInterval($scope.refresh, 10000);
        $scope.count = $timeout($scope.countdown,1000);
    }
    else
    {
        clearInterval($scope.timer); 
        $timeout.cancel($scope.count);
    }
}

倒计时函数--

    $scope.refresh = function(){
    div.style.visibility = "visible";
    $scope.update();
    $scope.timeoutsec = 11;
}

刷新功能--

    $scope.refresh = function(){
    div.style.visibility = "visible";
    $scope.update();
    $scope.timeoutsec = 11;
}

编辑： 更新功能--

    $scope.refresh = function(){
    div.style.visibility = "visible";
    $scope.update();
    $scope.timeoutsec = 11;
}

$scope.update（）=函数（）{
对于（var i=0；i如果使用xmlhttp请求，则必须将xhr.open（）函数中的第三个参数设置为true。这将使请求同步，如下所示：

 xhr.open(method, url, true);

下面是一些样板代码，让您看看如何实现它

(function() { 
    'use strict';

    angular.module('app')

        .controller('controller', function($scope, $http, $timeout, $q) {
            $scope.update = function () {

                // single request
                $http.get('url')
                    .then(function (data) {
                        $timeout($scope.update, 10000);
                    });

                // or with multiple requests
                var request1 = $http.get(/****/);
                var request2 = $http.get(/****/);
                var request3 = $http.get(/****/);

                $q.all([request1, request2, request3])
                    .then(function() {
                        $timeout($scope.update, 10000);
                    });
            }; 
        });
})();

初始化$scope.running为false，仅当按下自动刷新按钮时，running才应设置为true

    $scope.running = false;

自动刷新函数-

    $scope.autoRefresh = function(){
    $scope.running = !$scope.running;
    $scope.timeoutsec = 10;
    if($scope.running)
    {
        $scope.count = $timeout($scope.countdown,1000);
    }
    else
    {
        $timeout.cancel($scope.count);
    }
}

倒计时函数--

    $scope.refresh = function(){
    div.style.visibility = "visible";
    $scope.update();
    $scope.timeoutsec = 11;
}

刷新功能---

惠纳尔函数--

    $scope.refresh = function(){
    div.style.visibility = "visible";
    $scope.update();
    $scope.timeoutsec = 11;
}

所有（承诺）时的功能{
变量i，数据=[]，
dfd=$.Deferred（）；
对于（i=0；i<0.length；i++）{
承诺[i].done（函数（newData）{
data.push（newData）；
if（data.length==promissions.length）{
解析（数据）；
}
}).fail（函数（）{
数据推送（“无数据”）；
if（data.length==promissions.length）{
解析（数据）；
}
});
}
返回dfd.promise（）；
}

将所有ajax查询推送到$scope.querys。
将所有$http ajax推送到一个数组中，就像这样，因为$http return承诺，所以可以使用$q API在所有请求完成时进行处理：

var httpPromises = [
    $http({method:'GET', url: '/myjson0.json'}),
    $http({method:'GET', url: '/myjson1.json'}),
    $http({method:'GET', url: '/myjson2.json'}),
    $http({method:'GET', url: '/myjson3.json'})
];


//handle your requests like you would normally do
httpPromises[0].success(...).fail(...);
httpPromises[1].success(...).fail(...);
httpPromises[2].success(...).fail(...);
httpPromises[3].success(...).fail(...);

// remember to inject $q in your controller/factory
$q.all(httpPromises,function(){
    //start your timer here
});

什么是ajax查询？请显示所有相关代码。此处不显示您的查询，但如果是我们正在讨论的
$http
或
$resource
请求（即返回承诺），这听起来像是
$q.all（[promise1，promise2，promise3]）。然后（回调）；
var httpPromises = [
    $http({method:'GET', url: '/myjson0.json'}),
    $http({method:'GET', url: '/myjson1.json'}),
    $http({method:'GET', url: '/myjson2.json'}),
    $http({method:'GET', url: '/myjson3.json'})
];


//handle your requests like you would normally do
httpPromises[0].success(...).fail(...);
httpPromises[1].success(...).fail(...);
httpPromises[2].success(...).fail(...);
httpPromises[3].success(...).fail(...);

// remember to inject $q in your controller/factory
$q.all(httpPromises,function(){
    //start your timer here
});
