Should a controller call a service or factory?

This question already has an answer here: angular.service vs angular.factory 9 answers Use factory if object definition syntax is preferable app.factory('factory', function () { ... return { value: '...' }; }); or it returns something that is not an object for some reason. Use service if this syntax is preferable app.service('service', function () { this.value = '

控制器是否应该拨打服务或工厂?

这个问题在这里已经有了答案: angular.service vs angular.factory 9个答案 如果对象定义语法更可取,请使用factory app.factory('factory', function () { ... return { value: '...' }; }); 或者由于某种原因返回不是对象的东西。 如果this语法更可取,请使用service app.service('service', function () { this.value = '...'; }); 或者它应该返回与创建的对象new从另一个构造函数,如 ap

jQuery DOM manipulation with each();

I'm trying to do some simple DOM manipulation on several elements at once with jQuery using each(). I'm getting results that I don't understand. Here is a jsFiddle that shows what I want to happen VS what actually happens: http://jsfiddle.net/kthornbloom/4T52A/2/ And here is the JS: // Step One: Append one blue box within each grey box $('.grey').append('<div class="blue"&

使用each()的jQuery DOM操作;

我试图用jQuery使用each()来同时对几个元素做一些简单的DOM操作。 我得到的结果我不明白。 这是一个jsFiddle,它显示了我想要发生的事情VS实际发生的事情: http://jsfiddle.net/kthornbloom/4T52A/2/ 这里是JS: // Step One: Append one blue box within each grey box $('.grey').append('<div class="blue"></div>'); // Step Two: Make one copy of the red box already there, and place it within

Not sending headers in IE9

I'm using jQuery Fileupload to upload files. Its not sending headers that I set to the server. Why is the Authorization header missing only in IE but passed in chrome? Here is the code: upload_photo: function(){ var url = '/api/v1/upload'; $('#photoupload').fileupload({ url: url, dataType: 'json', paramName: 'uploadFile', beforeSend: function ( xhr ) {

不在IE9中发送标题

我正在使用jQuery Fileupload来上传文件。 它没有发送我设置到服务器的头文件 。 为什么授权头只在IE中丢失,但通过chrome? 代码如下: upload_photo: function(){ var url = '/api/v1/upload'; $('#photoupload').fileupload({ url: url, dataType: 'json', paramName: 'uploadFile', beforeSend: function ( xhr ) { setHeader(xhr); $("#check_progress").html('true'

height is uneven. Larger space above text than under

I'm having issues with fonts such as Josefin Sans where the space above, and below the text is uneven. This makes it impossible to vertical align the text. Look at this http://jsfiddle.net/G5aVK/. HTML <div class="text"> Hello World </div> <div class="text2"> Hello World </div> CSS .text{ font-family: 'Josefin Sans'; font-size: 36px; backgro

高度不均匀。 文字上面的空间比下面的大

我遇到了诸如Josefin Sans这样的字体问题,上面的空间和下面的文字都不均匀。 这使得不可能垂直对齐文本。 看看这个http://jsfiddle.net/G5aVK/。 HTML <div class="text"> Hello World </div> <div class="text2"> Hello World </div> CSS .text{ font-family: 'Josefin Sans'; font-size: 36px; background: #ff0000; margin-bottom: 10px; } .text2{ font-family

AngularJS: Injecting service into a HTTP interceptor (Circular dependency)

I'm trying to write a HTTP interceptor for my AngularJS app to handle authentication. This code works, but I'm concerned about manually injecting a service since I thought Angular is supposed to handle this automatically: app.config(['$httpProvider', function ($httpProvider) { $httpProvider.interceptors.push(function ($location, $injector) { return { 'reques

AngularJS:将服务注入HTTP拦截器(循环依赖)

我正在尝试为我的AngularJS应用程序编写一个HTTP拦截器来处理身份验证。 此代码有效,但我担心手动注入服务,因为我认为Angular应该自动处理: app.config(['$httpProvider', function ($httpProvider) { $httpProvider.interceptors.push(function ($location, $injector) { return { 'request': function (config) { //injected manually to get around circular dependency pr

How can I determine if an angular factory/service has been previously injected

I have an angular factory that performs some tasks upon injection into other objects. In some cases, I inject the factory using $injector.get() and in other cases, it is injected through the function declaration of the controller, service, etc. I would like to determine if the factory has previously been injected. I could implement a Boolean value on the angular module and then trip the flag

我如何确定以前是否注入过角度工厂/服务

我有一个角色工厂,在注入其他对象时执行一些任务。 在某些情况下,我使用$ injector.get()注入工厂,而在其他情况下,它通过控制器,服务等的函数声明注入。 我想确定工厂以前是否已经注入。 我可以在角度模块上实现一个布尔值,然后在工厂初始化期间触发标志,但看起来很笨重。 是否有一个以前在角度模块的生命周期中注入的对象列表? 思考? 您可以尝试使用$注射器服务。 尽管您无法专门查看它是否已被注入并且

Does it make sense to use Require.js with Angular.js?

I'm a newbie to Angular.js and trying to understand how it's different from Backbone.js... We used to manage our packages dependencies with Require.js while using Backbone. Does it make sense to do the same with Angular.js? Yes it makes sense to use angular.js along with require.js wherein you can use require.js for modularizing components. I can point you to a seed project which use

使用Require.js和Angular.js是否合理?

我是Angular.js的新手,并试图了解它与Backbone.js的不同之处......我们曾经在使用Backbone时使用Require.js管理包依赖项。 用Angular.js做同样的事情有意义吗? 是的,使用angular.js和require.js是有道理的,其中您可以使用require.js来模块化组件。 我可以指出你使用both angular.js and require.js的种子项目。 希望有所帮助! 重申我认为OP的问题真的是: 如果我主要在Angular 1.x中构建应用程序,并且(隐式地)

Recursion in Angular directives

There are a couple of popular recursive angular directive Q&A's out there, which all come down to one of the following solutions: manually incrementally 'compile' HTML based on runtime scope state example 1 [stackoverflow] example 2 [angular jsfiddles page] don't use a directive at all, but a <script> template which refers to itself example 1 [google groups]

在Angular指令中递归

有几个受欢迎的递归角度指令Q&A在那里,这些问题都归结为以下解决方案之一: 根据运行时作用域状态手动逐步“编译”HTML 示例1 [stackoverflow] 示例2 [angular jsfiddles页面] 根本不要使用指令,而是引用自身的<script>模板 示例1 [Google群组] 第一个问题是你不能删除以前编译的代码,除非你理解了手动编译过程。 第二种方法存在的问题是...不是一个指令,而是错过了其强大的功能,但更迫切的是,它不能以

How do I write a service that return true/false in AngularJS?

I had been reading up on AngularJS Factory and Services and came across a lot of examples. But I'm not understanding the logic behind them and can't get them to work either. myApp.service('loginCheck', function(Facebook) { this.loggedIn = false; Facebook.login(function(response) { if (response.status == 'connected') { this.loggedIn = true; } }); }); I need to get this s

我如何编写一个在AngularJS中返回true / false的服务?

我一直在阅读AngularJS工厂和服务,并且遇到了很多例子。 但我不了解他们背后的逻辑,也无法让他们工作。 myApp.service('loginCheck', function(Facebook) { this.loggedIn = false; Facebook.login(function(response) { if (response.status == 'connected') { this.loggedIn = true; } }); }); 如果我对这个概念的理解是正确的,我需要得到这个服务来返回loggedIn变量。 我应该使用工厂吗? 我需要一直
