AngularJS - 处理重复的片段像页眉和页脚 [英] AngularJS - Handle repeated fragments like Header and Footer

问题描述

我一直在努力实现在角度JS应用页眉/页脚。我想将这些作为NG-包括在主要的index.html。但是，如果页眉和页脚是静态页面，这将工作过。我的情况略有不同......在登录页面没有显示页眉/页脚。这取决于你在或者没有登录其他网页，你必须表明欢迎用户[注销]或欢迎客人[登录]。

I have been trying to implement the header / footer in an Angular JS App. I was thinking of adding these as ng-include in the main index.html. However this would have worked if the header and footer are static pages. My case is slightly different... In Login page no header / footer is shown. Other pages depending on whether you are logged in or not, you have to show "Welcome user [ logout] " or "Welcome guest [ login ]".

我保存在rootScope登录信息以及设置在登录一个布尔值$ rootScope.isLoggedIn。最大的问题似乎是整个NG-包括不刷新上注销。因此，与NG-显示隐藏指令不会隐藏/显示上变化的DIV。采用NG-开关有人建议 - 它也进行同样的操作。

I save the login information in the rootScope as well as set a boolean $rootScope.isLoggedIn on login. The biggest problem seems to be that the whole ng-include is not refreshed on a logoff. Hence divs with ng-show hide directives will not hide/show on change. Somebody suggested using ng-switch - it also behaves the same way.

如果我移动头部code个人观点里面，然后一切都很好。

If I move the header code inside individual views then everything is fine.

推荐答案

使用在页眉/页脚的控制器，如ivarni建议。从我自己的（实验）的应用程序的一个例子：

Use a controller in the header/footer, as ivarni suggested. An example from an (experimental) app of my own:

在的index.html，标题会显示一个动态生成的菜单，登录/注销等：

In the index.html, the header will display a dynamically generated menu, login/logout etc:

<div id="navbar" class="navbar navbar-inverse navbar-fixed-top"
    x-ng-controller="NavbarCtrl" x-ng-include="'app/main/navbar.html'"></div>

的 NavbarCtrl 建立了应用程序/主/ navbar.html 模板的适当范围。该模板将如下所示（考虑到您的需求 - 以及不相关的细节删除）：

The NavbarCtrl builds the appropriate scope for the app/main/navbar.html template. The template would be as follows (taking into account your needs - and irrelevant details removed):

<div class="navbar-inner" x-ng-if="showHeader">
    <div class="container">
        <div>
            <ul class="nav">
                <li x-ng-repeat="menuEntry in menuEntries">
                    <a x-ng-href="#{{menuEntry.path}}">{{menuEntry.display}}</a>
                </li>
            </ul>
        </div>
    </div>
    <div x-ng-if="userData.loggedIn">
        Wellcome {{userData.userName}}!
        <a x-ng-click="logout()">Logout</a>
    </div>
    <div x-ng-if="!userData.loggedIn">
        <a x-ng-click="login()">Login</a>
    </div>
</div>

所以整个标记是取决于 showHeader 范围的变量隐藏。它动态地创建菜单（的菜单项）。并根据 userData.loggedIn ，相应的登录/注销信息。

So the entire markup is hidden depending on the showHeader scope variable. It creates the menu dynamically (menuEntries). And depending on userData.loggedIn, the appropriate Login/Logout message.
