Ember js controlling class bindings in repeating component

阅读更多关于 Ember js controlling class bindings in repeating component

问题 I have a component which is repeating inside an each loop. The component simply displays the title of a post (There could potentially be hundreds). The code below is successfully adding the class 'active' to a title element which is clicked. How can I remove class 'active' from all previous titles when a new one is clicked (So that only one title ever has the class active)? I originally tried doing this on the controller, but I couldn't work out how to set the isActive property on one

Where and how to include Ember model functions

阅读更多关于 Where and how to include Ember model functions

问题 I am working on a simple Ember app that shows ID's for list elements. The ID's are computed with simple functions based on the element sequence (and some other simple factors). For example: <div class="content-id element">[ELEMENT ID]</div> <div class="content-name">{{element.name}}</div> I don't want to hardcode the element id's into the JSON object, but rather compute them in a simple function. Would it be best to place this function in the route object or in the component? What's the

如何确定两个JavaScript对象的相等性？

阅读更多关于如何确定两个JavaScript对象的相等性？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 严格的相等运算符将告诉您两个对象类型是否相等。但是，有没有办法判断两个对象是否相等，就像 Java中的哈希码值一样？堆栈溢出问题 JavaScript中是否存在某种hashCode函数？与这个问题相似，但需要更多的学术答案。上面的场景演示了为什么必须要有一个，而我想知道是否有任何等效的解决方案。 #1楼如果您方便使用深层复制功能，则可以使用以下技巧在匹配属性顺序时仍使用 JSON.stringify ： function equals(obj1, obj2) { function _equals(obj1, obj2) { return JSON.stringify(obj1) === JSON.stringify($.extend(true, {}, obj1, obj2)); } return _equals(obj1, obj2) && _equals(obj2, obj1); } 演示： http ： //jsfiddle.net/CU3vb/3/ 理由：由于 obj1 的属性被一一复制到克隆，因此将保留它们在克隆中的顺序。并且，当将 obj2 的属性复制到克隆中时，由于 obj1 已经存在的属性将被简单地覆盖，因此它们在克隆中的顺序将得以保留。 #2楼这是我的版本

问题 Using ember-cli 0.1.2 and ember-cli-simple-auth 0.7.0, I need to invalidate the session both on client and server. As explained here I need to do something similar to the authenticate method making an ajax request to the server and ensuring its success before emptying the session: import Ember from 'ember'; import Base from "simple-auth/authenticators/base"; var CustomAuthenticator = Base.extend({ tokenEndpoint: 'http://127.0.0.1:3000/api/v1/auth/login', restore: function(data) { },

问题 I am looking into how to show proper deletion error message in ember when there is an error coming back from the server. I looked at this topic and followed its suggestion: Ember Data delete fails, how to rollback My code is just like it, I return a 400 and my catch fires and logs, but nothing happens, when I pause it in the debugger though and try to rollback, I get Error: Assertion Failed: calling set on destroyed object So A) I cannot rollback B) the error is eaten normally.
