Question

这是我的控制者：

queueApp.controller('userController', function ($scope, $routeParams, $interval, userService) {
    console.log("<In userController>");
});

应用：

var queueApp = angular.module('queueApp', ['ngRoute']);
queueApp.config(function ($routeProvider) {
    $routeProvider.when('/Doctor/:id*',
        {
            title: 'Doctors',
            controller: 'userController',
            templateUrl: '/Scripts/User/Index.html'
        });
});

_Layout页面中有对这些文件的引用（在我的ASP.NET MVC应用程序中）我已将ng-view属性添加到_Layout页面中的body元素，将ng-app="queueApp"标记添加到html元素。我得到了这条线 "<In userController>"打印两次，在控制器中调用web api服务时效率很低？！

更新：脚本/用户/ Index.html的HTML：

Answer 1

只需改变一下：

queueApp.controller('userController', function ($scope, $routeParams, $interval, userService) {
    console.log("<In userController>");
});

到此：

function userController($scope, $routeParams, $interval, userService) {
    console.log("<In userController>");
});

这可能会解决您的问题。

Answer 2

我的问题真的很难找到。最后，当网页缺少图像时，就会出现问题。 src缺少网址。这是在MVC 5 Web控制器上发生的。为了解决这个问题，当没有可用的真实图像时，我添加了透明图像。

<img alt="" class="logo" src="">

为什么Angularjs会两次调用控制器？
