With the continuous development of Web technology, website access speeds are becoming faster and faster. However, for some applications that require frequent page refreshes, such as blogs, news sites, or social media, even with a fast website, users still need to wait for each page to be fully loaded before they can obtain information or perform some operations. Pjax technology can help solve this problem, and using Pjax in ThinkPHP6 is also quite easy.
What is Pjax?
The whole process of Pjax is PushState Ajax. Simply put, it is a technique that partially refreshes the page to update the content of the website without refreshing the entire page. Pjax uses JavaScript and XMLHttpRequest technology to achieve this, combined with the new pushState API in HTML5 to enable the browser's URL to remain unchanged.
In Pjax, each page is divided into multiple parts, called "containers". Only update specific containers when the user clicks a link or submits a form. For example, in a blog page, one container can contain a list of all posts, while another container can display details of a selected post. The benefit of this is that specific content can be loaded faster, thereby improving the speed and performance of the website, while also improving the user experience.
Using Pjax in ThinkPHP6
To use Pjax in ThinkPHP6, you first need to install the Pjax plug-in. Install it like this:
composer require ngyuki/pjax
Then add the following code in the controller to enable pjax:
if ($this->request->isPjax()) { // 如果是Pjax请求,禁用布局文件 $this->view->engine->layout(false); }
In the view file, add the following code to determine which containers should be updated in the Pjax request:
// 设置pjax容器 <div id="pjax-container"> <?php echo $content; ?> </div> // 将pjax链接添加到页面 <a href="http://www.example.com/page" data-pjax="#pjax-container">下一页</a>
Here, #pjax-container
is the ID of the container that needs to be updated, and the data-pjax
attribute tells the browser which links should be processed in the Pjax request. When a user clicks a link, only the content within the container will update, while other page elements such as the header and footer will remain unchanged.
When you need to use the backend to render the view, you can set a pjax
variable on the template. If pjax
is enabled, ajax layout can be used. For example:
// 启用Pjax时使用不同的布局 if ($pjax) { $this->view->engine->layout('layouts/ajax'); }
In an ajax layout file, all header files, navigation and footer tags are usually removed to improve loading speed, and the corresponding content is replaced with JavaScript code.
Summary
Pjax technology can help you achieve faster page loading speeds and improve user experience. Using Pjax in ThinkPHP6 is also quite easy. You just need to install the Pjax plug-in, enable Pjax requests and determine the Pjax container. When using Pjax, you can also use corresponding backend rendering views to further improve performance.
