Framework7 - 环境

在本章中，我们将讨论如何安装和设置Framework7。

您可以通过两种方式下载Framework7 -

您可以使用Bower安装Framework7，如下所示 -

bower install framework7

成功安装Framework7后，您需要按照以下给出的步骤在您的应用程序中使用Framework7 -

Step 1 - 您需要使用以下命令安装gulp-cli来构建Framework7的开发和dist版本。

npm install gulp-cli

cli代表Gulp的命令行实用程序。

Step 2 - 必须使用以下命令全局安装Gulp。

npm install --global gulp

Step 3 - 接下来，安装NodeJS包管理器，它安装节点程序，以便更容易指定和链接依赖项。以下命令用于安装npm。

npm install

Step 4 - 可以使用以下命令构建Framework7的开发版本。

npm build

Step 5 - 构建Framework7的开发版本后，使用以下命令从dist/文件夹开始构建应用程序。

npm dist

Step 6 - 将您的应用程序文件夹保留在服务器中，然后运行以下命令以在应用程序页面之间进行导航。

gulp server

从CDNs下载Framework7库

CDN或内容分发网络是用于向用户提供文件的服务器网络。如果您在网页中使用CDN链接，则会将托管文件的责任从您自己的服务器转移到一系列外部服务器。这也提供了一个优势，如果您的网页的访问者已经从同一CDN下载了Framework7的副本，则不必重新下载。您可以将以下CDN文件包含在HTML文档中。

以下CDN用于iOS App layout -

<link rel = "stylesheet" 
   href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />

它用于将Framework7 iOS CSS库包含到您的应用程序中。

<link rel = "stylesheet" 
   href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.colors.min.css" />

它用于为您的应用程序包含Framework7 iOS相关颜色样式。

以下CDN用于Android/Material App Layout -

<script src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>

它用于将Framework7 JS库包含到您的应用程序中。

<script src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.material.min.css"></script>

它用于为您的应用程序包含Framework7 Material样式。

我们在本教程中使用了库的CDN版本。我们使用AMPPS（AMPPS是Apache，MySQL，MongoDB，PHP，Perl和Python的WAMP，MAMP和LAMP堆栈）服务器来执行我们的所有示例。

例子 (Example)

以下示例演示了在Framework7中使用简单应用程序，当您单击导航栏时，它将显示带有自定义消息的警报框。

      //you can control the background color of the Status bar
      <div class = "statusbar-overlay"></div>

               <div class = "navbar-inner">
                  <div class = "center sliding">My App</div>
                  <div class = "right">
                     <a href = "#" class = "link icon-only open-panel">
                        <i class = "icon icon-bars"></i>
                     </a>
                  </div>
               </div>
            </div>
            <div class = "pages navbar-through toolbar-through">
               <div data-page = "index" class = "page">
                  <div class = "page-content">

                                 <div class = "item-content">
                                    <div class = "item-inner">
                                       <div class = "item-title">Blog</div>
                                    </div>
                                 </div>
                              </a>
                           </li>
                        </ul>
                     </div>
                  </div>
               </div>
            </div>
            <div class = "toolbar">
               <div class = "toolbar-inner">
                  <a href = "#" class = "link">First Link</a>
                  <a href = "#" class = "link">Second Link</a>
               </div>
            </div>
         </div>
      </div>
      <script type = "text/javascript" 
         src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>
      <script>
         // here initialize the app
         var myApp = new Framework7();
         // If your using custom DOM library, then save it to $$ variable
         var $$ = Dom7;
         // Add the view
         var mainView = myApp.addView('.view-main', {
            // enable the dynamic navbar for this view:
            dynamicNavbar: true
         });
         //use the 'pageInit' event handler for all pages
         $$(document).on('pageInit', function (e) {
            //get page data from event data
            var page = e.detail.page;
            if (page.name === 'blog') {
               // you will get below message in alert box when page with data-page attribute is equal to "about"
               myApp.alert('Here its your About page');
            }
         })
      </script>
   </body>
</html>

接下来，再创建一个HTML页面，即envirmnt_about.html ，如下所示 -

envirmnt_about.html

<div class = "navbar">
   <div class = "navbar-inner">
      <div class = "left">
         <a href = "#" class = "back link">
            <i class = "icon icon-back"></i>
            <span>Back</span>
         </a>
      </div>
      <div class = "center sliding">My Blog</div>
      <div class = "right">
         <a href = "#" class = "link icon-only open-panel">
            <i class = "icon icon-bars"></i>
         </a>
      </div>
   </div>
</div>
<div class = "pages">
   <div data-page = "blog" class = "page">
      <div class = "page-content">
         <div class = "content-block">
            <h2>My Blog</h2>
            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>
         </div>
      </div>
   </div>
</div>

输出 (Output)

让我们执行以下步骤，看看上面给出的代码是如何工作的 -

将上述HTML代码保存为服务器根文件夹中的framework7_environment.html文件。
以http://localhost/framework7_environment.html打开此HTML文件，输出显示如下。
单击导航栏时，它将显示带有自定义消息的警告框。
