如何使用 app-UI 插件为手机设计页面视图导航？

本文的目的是通过使用 app-UI插件为移动设计提供交互式用户界面组件。在这里，我们将研究各种类型的网页导航视图。
该插件可帮助移动开发人员使用 HTML、CSS 和 JavaScript 创建应用程序。

请从链接下载所需的预编译文件并将其保存在您的工作文件夹中以供实施。请注意正确的文件路径，同时包含在您的源代码中。

基本示例：下面演示了使用 app-UI插件的页面视图导航器的基本 HTML 网页结构。

HTML

    
        
  
        
        
        
        
        
        
        
  
        
  
            $(document).ready( function() {
  
                // Setup the default view
                var defaultView = getView();
                defaultView.backLabel = null;
  
                // Setup the ViewNavigator
                window.viewNavigator = new ViewNavigator('body');
                window.viewNavigator.pushView( defaultView );
  
            });
            function pushView() {
  
                // Create a view and push it onto
                // the view navigator
                var view = getView();
                window.viewNavigator.pushView( view );
            }
            function popView() {
  
                // pop a view from the view navigator
                window.viewNavigator.popView();
            }
  
            function getView()
                       {
              // Create a view descriptor with random content
              var bodyView = $('<h3>Basic navigator using app-UI plugin</h3>'
                        + '<div>' + '<hr><li href="#" onclick="pushView()"
                        class="viewNavigator_backButton">
                        push view</li> <li href="#" onclick="popView()"
                        class="viewNavigator_backButton">pop view</li><hr>'
                        + getPageContent() + '</div>');
                var links = bodyView.find('a');
  
                return { title: "Default View "
                                    + parseInt(Math.random()*1000),
                         backLabel: "Back",
                         view:  bodyView
                };
            }
  
            function getPageContent() {
  
                var result = "";
                for ( var i = 0; i < 8; i ++ )
                                {
                  result +=
                       "Python is a high-level, general-purpose
