This question already has an answer here: 'this' vs $scope in AngularJS controllers 7 answers You need to realize that Javascript has multiple scopes and that the this keyword refers to the scope you are operating in. Then, like mentioned by @Henri S, you should also realize the scope of your controller, which is a JavaScript contructor function, is not the same as the $scope you ar
这个问题在这里已经有了答案： AngularJS控制器中的'this'与$ scope有关的7个答案 你需要认识到Javascript有多个作用域，而this关键字指的是你所在的作用域。 然后，就像@Henri S提到的那样，你也应该认识到你的控制器的范围，它是一个JavaScript构造器函数，与你在里面使用的$scope 。 Angular使用的$ scope是一个与控制器相关的对象，它真的是一个开始的视图模型。 你的HTML，在某个控制器的控制下，可以“访问
This question already has an answer here: 'this' vs $scope in AngularJS controllers 7 answers Snippet A is not working most likely because of how the controller is being attached. I am taking a wild guess here. Where you add ng-controller it should probably look something like: <body ng-controller="dishDetailController as dish"> Where as you might have this instead: <
这个问题在这里已经有了答案： AngularJS控制器中的'this'与$ scope有关的7个答案 由于控制器的连接方式，代码片段A很可能不工作。 我在这里大肆猜测。 在你添加ng-controller它应该看起来像这样： <body ng-controller="dishDetailController as dish"> 在哪里你可能会有这个： <body ng-controller="dishDetailController"> 可能不是身体标记可能是div或其他东西。 为了更好地理解片段A控
This question already has an answer here: 'this' vs $scope in AngularJS controllers 7 answers The function you put into angular.controller is used as a constructor. JavaScript constructors that return nothing, implicitly return this . If a constructor returns another object, then this object is supposed to be the new object. eg: function Class1() { this.prop = 'xxx'; } var obj
这个问题在这里已经有了答案： AngularJS控制器中的'this'与$ scope有关的7个答案 您将放入angular.controller的函数用作构造函数。 不返回任何内容的JavaScript构造函数，隐式返回this 。 如果构造函数返回另一个对象，则该对象应该是新对象。 例如： function Class1() { this.prop = 'xxx'; } var obj1 = new Class1(); console.log(obj1.prop); // prints 'xxx' function Class2() { this.prop = 'x
I am trying to make a bootstrap side menu that makes sub items collapsible. Similar to http://jsfiddle.net/ However I want link items in the submenus and not such a complicated structure. This is what I tried <div class="row"> <!-- Main component for a primary marketing message or call to action --> <div class="col-sm-3 col-md-2 sidebar"> <ul cl
我正在尝试制作一个引导子菜单，使子项可折叠。 类似于http://jsfiddle.net/然而，我想链接子菜单中的项目，而不是这样一个复杂的结构。 这是我试过的 <div class="row"> <!-- Main component for a primary marketing message or call to action --> <div class="col-sm-3 col-md-2 sidebar"> <ul class="nav nav-sidebar"> <li class="dropdown">
function Ninja(){ this.swingSword = function(){ return true; }; } // Should return false, but will be overridden Ninja.prototype.swingSword = function(){ return false; }; var ninja = new Ninja(); log( ninja.swingSword(), "Calling the instance method, not the prototype method." ); now log showing me true. which means swingSword that were defined in Ninja.prototype has overridden so ho
function Ninja(){ this.swingSword = function(){ return true; }; } // Should return false, but will be overridden Ninja.prototype.swingSword = function(){ return false; }; var ninja = new Ninja(); log( ninja.swingSword(), "Calling the instance method, not the prototype method." ); 现在日志显示我是真的。 这意味着在Ninja.prototype中定义的swingSword已被覆盖，所以如何重写构造函数或属性。
while working on web-services in spring REST with angular I am not able to perform any action on it as following is my code @cartRestcontroller @RestController @RequestMapping("/rest/cart") public class CartRestController { @RequestMapping(value = "/add/{productId}", method = RequestMethod.PUT) @ResponseStatus(code = HttpStatus.NO_CONTENT) public void addItem(String productId, HttpServle
在Spring中使用角度的REST Web服务时，我无法对其执行任何操作，因为以下代码是我的代码@cartRestcontroller @RestController @RequestMapping("/rest/cart") public class CartRestController { @RequestMapping(value = "/add/{productId}", method = RequestMethod.PUT) @ResponseStatus(code = HttpStatus.NO_CONTENT) public void addItem(String productId, HttpServletRequest request) { String session
I created an AngularJS factory that I reuse for data access: app.factory('abstractFactory3', function ($http) { function abstractFactory3(odataUrlBase) { this.odataUrlBase = odataUrlBase; } abstractFactory3.prototype = { getList: function (odataOptions) { return $http.get(this.odataUrlBase, { params: odataOptions }); }
我创建了一个可以重新用于数据访问的AngularJS工厂： app.factory('abstractFactory3', function ($http) { function abstractFactory3(odataUrlBase) { this.odataUrlBase = odataUrlBase; } abstractFactory3.prototype = { getList: function (odataOptions) { return $http.get(this.odataUrlBase, { params: odataOptions }); }, g
I have made changes in my index.html and app.js. This is app.js file. angular .module('assessmentApp', ['ngRoute', 'ngCookies', 'ngSanitize', 'timer', 'assets', 'youtube-embed']) .config(config) .run(run); config.$inject = ['$routeProvider', '$locationProvider', '$httpProvider']; function config($routeProvider, $locationProvider, $httpProvider) { /*$l
我在我的index.html和app.js中进行了更改。 这是app.js文件。 angular .module('assessmentApp', ['ngRoute', 'ngCookies', 'ngSanitize', 'timer', 'assets', 'youtube-embed']) .config(config) .run(run); config.$inject = ['$routeProvider', '$locationProvider', '$httpProvider']; function config($routeProvider, $locationProvider, $httpProvider) { /*$locationProvi
So I have some plugins and libraries I want to use in my angular app and (currently) I am simply referencing those functions/methods as they were intended in 99% of apps in a way that completely ignores dependency injection. I have (for example) the javascript library "MomentJS" which deals with formatting and validating dates and I have uses for it throughout my app in controllers, s
所以我有一些插件和库我想用在我的角度应用程序和（目前）我只是简单地引用这些函数/方法，因为它们是在99％的应用程序中打算完全忽略依赖注入的方式。 我有（例如）处理格式化和验证日期的JavaScript库“MomentJS”，并且我在控制器，服务和过滤器中通过我的应用程序使用它。 我学习的方式（使用AngularJS）是创建一个引用该函数（及其方法）的服务，并将该服务注入到我的控制器中，这非常有效。 问题是，我真的需要从服务，
I'm building a weather app where I first have to get the users location, then make the request to get the weather. So I have a GeolocationService and a WeatherService . My WeatherService is currently calling the Geolocation Service. How do I make the WeatherService wait until it has the results from the GeolocationService before making the HTTP request? app.factory('GeolocationServic
我正在构建一个天气应用程序，首先必须获取用户位置，然后提出请求以获取天气。 所以我有一个GeolocationService和一个WeatherService 。 我的WeatherService目前正在调用Geolocation服务。 在进行HTTP请求之前，如何让WeatherService等待GeolocationService的结果？ app.factory('GeolocationService',function($q,$window,$rootScope){ return { getLatLon: function(){ var defe
