我试图进行登录身份验证，我尝试使用angularJS显示进度来看，是这样的：

 的app.config（函数（$ locationProvider，$ routeProvider）{    $ routeProvider            。什么时候（'/'， {                模板：，                控制器：的IndexController            }）            。当（'/主'，{                templateUrl：意见/ main.html中，                控制器：MainController            }）            。当（'/登录'，{                templateUrl：意见/ login.html的，                控制器：的LoginController            }）            。当（'/进步'，{                templateUrl：意见/ progress.html'，                控制器：ProgressController            }）        }）;VAR LOGGED_IN = FALSE;函数索引控制器（$范围，$位置）{    如果（LOGGED_IN）{        $ location.path（/主）;    }其他{        $ location.path（/登录）;    }}功能validateEmail（电子邮件）{    VAR重= /^(([^<>()[\\]\\\\.,;:\\s@\\\"]+(\\.[^<>()[\\]\\\\.,;:\\s@\\\"]+)*)|(\\\".+\\\"))@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\])|(([a-zA-Z\\-0-9]+\\.)+[a-zA-Z]{2,}))$/;    返回re.test（电子邮件）;}功能的LoginController（$范围，$位置）{    $ scope.username =;    $ scope.password =;    $ scope.login =功能（）{        如果（$ scope.username =！＆放大器;＆安培; $ scope.password！=）{            如果（！validateEmail（$ scope.username））{                警报（无效的邮件！）;            }其他{                $ location.path（/进展）;                的setTimeout（函数（）{// JUST FOR测试之前添加AJAX控件                    LOGGED_IN = TRUE;                    $ location.path（/主）; //不调用MainController并且不改变模板                }，2000）;            }        }其他{            警报（用户名和放大器;密码obbligatori！）;        }    };    $ scope.register =功能（）{    };}功能ProgressController（$范围）{    $ scope.loading = TRUE;}功能MainController（$范围）{} 

在这里progress.html包含

 ＆LT; D​​IV NG秀=加载类='装入'＆GT;  ＆LT; IMG SRC =IMG / loading.gif'＆GT;＆LT; / DIV＆GT; 

解决方案

我认为你应该使用 $超时

http://$c$c.angularjs.org/1.2.13/docs/api/ng.$timeout

$超时（函数（）{  LOGGED_IN = TRUE;  $ location.path（/主）;}，2000）;

当然，它需要注入的控制器$超时。

i'm trying to perform login auth and i'm trying to show a progress view using angularJS, something like:

app.config(function($locationProvider,$routeProvider) {
    $routeProvider
            .when('/', {
                template: " ",
                controller  : IndexController
            })
            .when('/main', {
                templateUrl : 'views/main.html',
                controller  : MainController
            })
            .when('/login', {
                templateUrl : 'views/login.html',
                controller  : LoginController
            })
            .when('/progress', {
                templateUrl : 'views/progress.html',
                controller  : ProgressController
            })
        });


var logged_in = false;
function IndexController($scope,$location){
    if(logged_in){
        $location.path("/main");
    }else{
        $location.path("/login");
    }
}
function validateEmail(email) {
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(email);
}
function LoginController($scope,$location){
    $scope.username   = "";
    $scope.password   = "";
    $scope.login = function(){
        if($scope.username!="" && $scope.password!=""){
            if(!validateEmail($scope.username)){
                alert("Invalid e-mail!");
            }else{
                $location.path("/progress");
                setTimeout(function(){ // JUST FOR TEST BEFORE ADD AJAX CONTROL
                    logged_in = true;
                    $location.path("/main"); // DOES NOT CALL MainController AND DOES NOT CHANGE TEMPLATE
                },2000);
            }
        }else{
            alert("Username & Password obbligatori!");
        }
    };
    $scope.register = function(){

    };
}
function ProgressController($scope){
    $scope.loading       = true;
} 
function MainController($scope){}

where progress.html contains

<div ng-show="loading" class='loading'>
  <img src='img/loading.gif'>
</div>

I think you should use $timeout

http://code.angularjs.org/1.2.13/docs/api/ng.$timeout

$timeout(function(){ logged_in = true; $location.path("/main"); },2000);

Of course it needs to inject $timeout in controller.
