Framework7 - 从 HTML 打开和关闭弹出窗口

描述

所需的弹出窗口可以使用链接上的特殊类和数据属性来打开和关闭。以下语句简要描述了如何打开/关闭弹出窗口 -

要打开弹出窗口，请向任何 HTML 元素添加 open-popover 类，并且可以使用 close-popover 类关闭弹出窗口。
当您在应用程序中有多个弹出窗口时，需要将 data-popover=".mypopover" 属性指定到相应的弹出窗口。
当使用此方法（从 HTML）打开弹出窗口时，弹出窗口将自动放置在我们点击以调用此弹出窗口的元素周围。

示例

以下示例演示了在 Framework7 中从 HTML 打开和关闭弹出窗口 -

<!DOCTYPE html>
<html>

   <head>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1, 
         maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />
      <meta name = "apple-mobile-web-app-capable" content = "yes" />
      <meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
      <title>Open and close Popover From HTML</title>
      <link rel = "stylesheet" 
         href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
      <link rel = "stylesheet"

输出

让我们执行以下步骤来了解上面给出的代码是如何工作的 -

将上面给出的 HTML 代码保存为 popover_open_close_html.html 文件，放在您的服务器根目录文件夹中。
以 https:///popover_open_close_html.html 的方式打开此 HTML 文件，输出结果如下所示。
当您点击第一个链接时，将打开关于弹出窗口。类似地，当您点击第二个链接时，将打开具有多个菜单项的菜单弹出窗口。
菜单和关于弹出窗口也可以通过点击顶部的菜单和关于选项来打开。弹出窗口将从 HTML 中打开和关闭。

当您点击链接时，弹出窗口将使用 popover 类打开，如果您点击鼠标外部，弹出窗口将关闭。
