问题 In AngularJS, I wonder how to prevent the elements shown on page before ng-show take effect, I found some posts talk about ng-cloak, but it seems not work in my case, probably the ng-cloak is for prevent double curly bracket rather than Element style. Another way someone talk about is define some style for before AngularJS initialized, but that is kinda hard to manage. Is there some official way to handle this? 回答1: Unless you want to show a loader, ng-cloak should be your solution. Official

I am looking for some help with my code I have so far. The main objective is to be able to click on any Plus icon and have it place a cover over all other div blocks. And when a plus icon is clicked it will also show a div block to the right. As you will see when block 2 is clicked it does all that is intended. I am looking for an efficient way to do this with Angular when any plus icon is clicked. This is just a small sample I show here, in reality there would be 10 to 20 blocks to cover. If someone could see a way to use less code here and make better use of the scope, this would be greatly

前几天装了一下stf环境 , mac环境搭建stf 环境搭建还是比较简单的。这个平台登陆的时候是没有限制的，只要输入个名称和邮箱就可以登陆。打算修改一下，改成公司内部账号登陆，下面来撸一撸代码。这张图片是在网上找的，根据这个区分出来了前端和后端代码。 stf前端使用的是angularjs语言开发的（测试小白，以前没有听过?），后端是nodejs（对于使用Java的我来说，这两个语言有点懵）没办法现学现卖，先去看看基本语法，然后在结合stf源码慢慢啃吧。打开stf地址是http://192.168.110.18:7100/auth/mock/ 在res路径下面找到了前端代码，修改.pug文件可以改变前端页面渲染。先打开signin.pug把邮箱和name换一下，把name输入框换成password输入框。 .login2(ng-controller='SignInCtrl') .login-wrapper a(href='./') img(width='200', height='85', src='/static/logo/exports/STF-512.png', title='STF') form(name='signin', novalidate, ng-submit='submit()') .alert.alert-danger(ng-show='error')

I'd like a ← Back to home link to appear below the nagivation on every page of my Angular app except the home page. So I'd like to conditionally add the link and hide it using ng-hide if the url is already on the home page (view) of the app. I've tried using angular's $location service with no success <p ng-hide="location.hash == '#/'" class="container"><a href="#topics">← Back to Home</a></p> I've tried the following variations: ng-hide="location.hash == '#/' " //console.log shows true ng-hide="location.hash === '#/' " //console.log shows true ng-hide="location.hash == '' " //console.log

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: When using ng-show/-hide, the content included in those blocks initially displays on the user screen. Only after few milliseconds (after angular.js has loaded and executed) does the right block show up in ng-show. Is there a better way than ng-show/-hide to load only the relevant section of data into the DOM? The problem with ng-view is that I can have only one on the page, so I have to toggle the behavior of many sections of the DOM based on the current state. 回答1: To avoid the "flash of uncompiled content", use ng-bind instead of {{}} or

ng-show disturbing div layout - angularJS

阅读更多关于 ng-show disturbing div layout - angularJS

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I am using ng-show="!notesOpened" to hide a div if the notesOpened variable is true. However when hidden it messes up layout. Is there a way to make ng-show act in the same way as the css property visibility:hidden ? so that all div elements around the div being hidden stay in the same place 回答1: ng-hide uses the same property that you're referring to, i.e. display: none . If you need to achieve this, you need to use visibility: hidden; For that you can use the ng-class attribute. eg: ng-class="{'vis-hidden': notesOpened==true}" .vis-hidden{

问题 Inline in AngularJs is there a way to check if something is an array? I would have thought this to work: <div ng-show="Array.isArray(textStuff[0][1])">Hi</div> I have verified it is in fact an array. Is there something I am missing or another way? 回答1: You can put angular.isArray on the scope... $scope.isArray = angular.isArray; <div ng-show="isArray(textStuff[0][1])">Hi</div> Fiddle 回答2: You can create global filters to use in your JS or HTML to check against object types. This way you don't
