导航条不呈现，只显示纯文本

md-nav-bar not rendering, only showing plain text

本文关键字：显示 文本 导航      更新时间：2023-09-26

我有一个问题与Angular材质指令"md-nav-bar"。它不是在我的代码渲染。我试着复制各种工作代码，但我没有设法让它运行。

<body ng-app="app" ng-controller="MainController">
<md-content layout="row">
    <md-toolbar class="md-hue-2">
        <div class="md-toolbar-tools">
            <md-button class="md-icon-button" aria-label="Home" href="#/welcome">
                <i class="material-icons">explore</i>
            </md-button>
            <h2 href="#/welcome">
                md-nav-bar Test
            </h2>
            <span flex></span>
            <md-button class="md-icon-button" aria-label="Coontact Us" href="mailto:info@osterdach.de">
                <i class="material-icons">email</i>
            </md-button>
            <md-button class="md-icon-button" aria-label="Call Us" href="tel:+4915732224836">
                <i class="material-icons">phone</i>
            </md-button>
        </div>
    </md-toolbar>
</md-content>
<md-content>
    <md-nav-bar md-selected-nav-item="currentNavItem" nav-bar-aria-label="navigation links">

查看此笔与我的代码:http://codepen.io/anon/pen/pbBOdv

你需要加载Angular Material的CSS文件并更新JS文件- CodePen

CSS: https://cdn.gitcdn.link/cdn/angular/bower-material/v1.1.0/angular-material.css

JS: http://ajax.googleapis.com/ajax/libs/angular_material/1.1.0-rc.5/angular-material.min.js

您还需要使每个md-nav-item的name唯一:

<md-nav-item md-nav-href="#/holzbau" name="page1">Holzbau</md-nav-item>
<md-nav-item md-nav-href="#/dach" name="page2">Dach</md-nav-item>
<md-nav-item md-nav-href="#/fassade" name="page3">Fassade</md-nav-item>
<md-nav-item md-nav-href="#/erhaltUndEnergie" name="page4">Erhalt und Energie</md-nav-item>
