Framework7 - 使用 JavaScript 显示选项卡

说明

您可以使用以下 JavaScript 方法切换或显示选项卡。

myApp.showTab(tab)

• tab − 这是用于打开选项卡的必需 HTML 元素或字符串。

如果选项卡已更改，则此方法返回 true，否则返回 false。

示例

以下示例演示了在 Framework7 中使用 JavaScript 显示选项卡的用法 −

<!DOCTYPE html>

输出

让我们执行以下步骤来查看上述代码的工作原理 −

• 将上述 HTML 代码保存为服务器根文件夹中的 show_tab_using_js.html 文件。

• 以 http://localhost/show_tab_using_js.html 的形式打开此 HTML 文件，输出如下所示。

• 此示例可以在选项卡内切换或显示另一个选项卡的内容。
