Framework7 - Template7 页面

描述

Template7 是一个移动优先的 JavaScript 模板引擎，具有类似handlebars.js 的语法。它是 Framework7 中超轻量且速度极快的默认模板引擎。

首先，我们需要在应用程序初始化时传递以下参数，将所有 Ajax 和动态页面呈现为 Template7 模板 -

var myApp = new Framework7 ({
   template7Pages: true // enable Template7 rendering for Ajax and Dynamic pages
});
序列号 Template7 页用法和说明
1 模板/页面数据

您可以通过在初始化应用程序时发送的template7Data参数中指定所有页面数据来传递特定页面所需的数据/上下文。
2 传递自定义上下文

Framework7 允许您将自定义上下文传递到任何动态页面或任何加载的 Ajax。
3 直接加载模板

您可以将模板动态渲染和加载为动态页面。
4 网址查询

如果您使用 Template7 来呈现 Ajax 页面，则其上下文始终将使用特殊属性url_query进行扩展。
