Angular7教程 - HelloWorld开发者社区

1. 本节说明

本节以及后面的内容我们将会通过搭建一个简单的博客程序来对angular进行介绍，项目使用前端框架是bootstrap.版本v3.3.7，另外需要安装jquery.关于bootstrap,jquery的安装方法第一篇中有讲解，不再赘述。本节内容由于搭建页面框架的关系，主要是bootstrap的内容，与angular关系不太大。最后的效果如下：

Angular7教程

2. 搭建框架

首先，我们将上面的页面大致分为5个区域，分别是头部（header)，轮播图（carousel)，文章区域(article)，侧边栏（sidebar),底部（footer）。

进入到项目目录，分别创建这5个组件：

ng g c header
ng g c carousel
ng g c artile
ng g c sidebar
ng g c footer

3. 编写模板文件和CSS文件

主要是bootstrap和css的内容，下面贴出文件的源码，不再做详细解释：

3.1. `app.component.html`

<app-header></app-header>
<div class="container">
    <div class="row">
        <div class="col-md-9">
            <app-carousel></app-carousel>
            <app-article></app-article>
        </div>
        <div class="col-md-3">
            <app-sidebar></app-sidebar>
        </div>
    </div>
</div>
<app-footer></app-footer>

3.2. 全局样式文件 `style.css`

/* You can add global styles to this file, and also import other style files */
html,body{
    margin: 0;
    padding: 0;
    font-size: 12px;
    background-color: rgb(243,243,243) !important;
}
body{
    padding-top: 70px;
}

3.3. `header.component.html`

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".navbar-ex">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a href="" class="navbar-brand">博客家</a>
        </div>
        <div class="collapse navbar-collapse navbar-ex">
            <ul class="nav navbar-nav">
                <li><a href="#">首页</a></li>
                <li><a href="#">联系我们</a></li>
                <li><a href="#">关于我们</a></li>
            </ul>
            <form class="navbar-form navbar-left">
                <div class="form-group">
                    <input type="text" class="form-control" placeholder="搜索内容">

                &nbsp;<button type="submit" class="btn btn-default">Search</button>
            </form>
            <div class="navbar-nav navbar-right">
                <button class="navbar-btn btn btn-info">登录</button>&nbsp;
                <button class="navbar-btn btn btn-defualt">注册</button>
            </div>
            <!--
            <ul class="nav navbar-nav navbar-right">

                    <span class="glyphicon glyphicon-user"></span> <span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">我的博客</a></li>
                        <li><a href="#">我的收藏</a></li>

                    </ul>
                </li>
