ThinkPHP is a very popular PHP development framework, which is designed for rapid development of web applications. When developing web applications through ThinkPHP, we may need to create a single-page official website. This article will introduce how to use ThinkPHP to set up a single-page official website.

1. What is a single-page application?

Single-page application, English is Single-Page Application, referred to as SPA. It is a kind of technology based on Ajax and HTML5, which dynamically loads part of the page. content to optimize the user experience of web applications. Unlike traditional applications, single-page applications only contain one HTML page, and the page content is dynamically loaded through JavaScript to achieve content presentation and switching between pages.

2. Create a single-page application

There are many ways to create a single-page application in ThinkPHP, and this article will introduce one of them.

1. Create a controller

In ThinkPHP, all business logic is implemented in the controller. Therefore, we need to create the controller of the single page application in the application's controller. We create a controller called SinglePageController.

<?php
namespace app\index\controller;
use think\Controller;
class SinglePageController extends Controller
{
    public function index()
    {
        return view();
    }
}

In the above code, we define a SinglePageController class that inherits from the Controller class, and defines an index method, which will perform the page loading operation.

2. Create a view

We need to create a single-page application view through ThinkPHP's view engine. ThinkPHP's view engine allows us to embed PHP code in HTML to achieve view reuse and page separation.

<!-- singlepage.html -->
<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>单页应用</title>
    <script src="//cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
    <div id="nav">
        <ul>
            <li><a href="#home">首页</a></li>
            <li><a href="#about">关于我们</a></li>
            <li><a href="#product">产品介绍</a></li>
            <li><a href="#contact">联系我们</a></li>
        </ul>
    </div>
    <div id="content"></div>
    <script type="text/javascript">
        $(document).ready(function(){
            $(window).bind('hashchange', function() {
                var url = window.location.hash.slice(1);
                $('#content').load(url + '.html');
            });
            $(window).trigger('hashchange');
        });
    </script>
</body>
</html>

Copy after login

In the above code, we created a navigation bar with id nav and a content area with id content. And we have bound the hashchange event in JavaScript. Whenever the hash changes (that is, when the navigation bar link changes), we will load the corresponding HTML page into the content area through Ajax.

Note: The content of a single-page application should be composed of multiple HTML pages, rather than all displayed on one page at the same time.

3. Define routing rules

Since our SinglePageController class renders the view of a single-page application through the index method, we need to define a routing rule named singlepage in the routing rules:

<?php
use think\Route;
// 单页应用路由
Route::rule('singlepage/:id','index/SinglePage/index');

Copy after login

In the above code, we define a routing rule named singlepage and pass the id as a parameter to the index method of the SinglePageController class.

3. Summary

Single-page applications are an important form of modern Web applications. As a commonly used Web framework, ThinkPHP provides many convenient methods for users to create single-page applications. This article introduces a method to create a single-page application by creating controllers and views, and defining routing rules.
