As a senior CMS website operation personnel of an enterprise security, I know that the details of content presentation are crucial to user experience.Especially for websites involving professional fields such as mathematical formulas, ensuring content is presented in the clearest and most standardized way is crucial for attracting and retaining users.MathJax-scriptThis is the behind-the-scenes hero that implements this function.

This article will discuss in detail.MathJax-scriptThe placement and reasons in the Anqi CMS template, helping you optimize the display of website content.


Understand the template structure of the Anqi CMS.

In the AnQi CMS, the template is the skeleton for displaying website content. According to our development specifications, template files are usually stored in/templateDirectory, and uses syntax similar to Django template engine.base.htmlPlaying a core role, it is the basic template for all pages (such as article detail pages, category list pages, single pages, etc.). This means that any inbase.htmlThe elements defined in it, including style sheets, meta tags, and scripts, will be automatically inherited by all pages that inherit it. Static resources, such as CSS, JavaScript, and images, are stored in a unified manner./public/static/directory.

MathJax-scriptThe function and loading requirements

MathJaxis a cross-browser JavaScript library for displaying mathematical formulas in web browsers.It can render mathematical expressions in formats such as LaTeX, MathML, or AsciiMath into high-quality, scalable formulas.MathJaxThe script needs to be executed after the HTML containing mathematical content has been loaded, so that it can find and process these formulas.

MathJax-script placement

According to the official documentation of Anqi CMShelp-markdown.mdThe guidance inside,MathJax-scriptThe placement of the ** is in the template you are currently using,base.htmlthe file<head>Specific code snippets are as follows inside the tag:

<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>

Why choosebase.htmlof<head>?

toMathJax-scriptplaced inbase.htmlof<head>The tag is inside due to the following key considerations:

Firstly,Ensure global coverage and consistency.Due tobase.htmlIs the basis for all pages, placing it here means that all pages on your website, as long as the Markdown editor is enabled and contains mathematical formulas, will automatically receive MathJax support.This avoids the繁琐 of adding scripts separately for each page that may contain formulas, ensuring the consistency and convenience of the full-site mathematical formula rendering.

Secondly,Optimize user experience, avoid content flicker.toMathJax-scriptPlace at the top of the page, ensuring that the script starts working as soon as the page content is loaded and parsed.This helps to complete the rendering of mathematical formulas before the user sees the page content.If loaded at the bottom of the page, users may briefly see unrendered original LaTeX code (commonly known as 'Flash of Unstyled Content' or FOUC), which can greatly affect the reading experience.

Finally,UtilizeasyncProperties are loaded non-blocking.The script loading method provided in the document uses.asyncProperties. This means thatMathJax-scriptIt will be downloaded in the background asynchronously without blocking the parsing of the HTML document.When the script has been downloaded, it will execute at the pause of HTML parsing.This approach ensures that the script can be discovered and downloaded by the browser as early as possible, while also minimizing the impact on the initial rendering speed of the page. It is a good practice that balances performance and functional requirements.

Specific operation steps

  1. Log in to your Anqi CMS backend.
  2. Navigate to the "Template Design" area, find the template folder you are currently using.
  3. Find and edit in the template folder.base.htmlfile.
  4. In<head>Within the tag, usually other<meta>or<link>After the tag,</head>Label before, paste the aboveMathJax-scriptCode.
  5. Savebase.htmlfile.
  6. Important reminder:Ensure that you have enabled the Markdown editor in the Anqi CMS backend, usually located at “Anqi CMS backend -> Global Settings -> Content Settings”.This is because MathJax is usually used to render mathematical formulas in Markdown content, and enabling the Markdown editor is a prerequisite for its normal operation.

Through these steps, your CMS website will be able to efficiently and elegantly display content containing mathematical formulas, thereby enhancing professionalism and user satisfaction.


Common Questions and Answers (FAQ)

1. Q: If my website only has a few pages that require mathematical formulas, can I place the MathJax script elsewhere?

A:Certainly. Although it is)MathJax-scriptplacedbase.htmlof<head>Tags within are the most general and recommended practice to ensure that all pages can support mathematical formulas, but if you are sure that only a very few specific pages need this feature, you can consider adding this script directly to the template files of these pages (for example, the template of some article detail page)archive/detail.html) of<head>Section.This can reduce the overhead of loading unnecessary resources on pages that do not require MathJax functions.But please make sure that the script is loaded before any mathematical formula content is rendered.

2. Q: Why is it recommended to useasyncproperties to load the MathJax script? What will be the impact of removing it?

A: asyncThe attribute is a feature introduced in HTML5, which allows the browser to asynchronously download script files in the background without blocking the parsing of the HTML document and the rendering of the page.This means that users can see the main content of the page faster.Once the script is downloaded, it will execute when HTML parsing pauses.asyncis a very good choice, as it ensures that the script is executed while minimizing the perceived impact on the initial page loading speed. If removedasyncProperties, the script will become synchronous loading, which will block HTML parsing until the script is downloaded and executed, which may cause the page loading speed to slow down and increase the waiting time for users.

3. Q: In adding to the template, the mathematical formula still cannot be displayed correctly, how should I troubleshoot the problem?MathJax-scriptAfter adding to the template, the mathematical formula still cannot be displayed correctly, how should I troubleshoot the problem?

A:If the MathJax script has been added but the formulas are still not displayed correctly, you can check from the following aspects:

*   **启用Markdown编辑器:** 确认在安企CMS后台的“全局设置 -> 内容设置”中,您已经启用了Markdown编辑器。MathJax通常用于渲染Markdown内容中的公式,这是其工作的前提。
*   **检查代码片段准确性:** 仔细核对您添加到`base.html`中的`MathJax-script`代码是否完全正确,包括URL和`async`属性。任何拼写错误或遗漏都可能导致脚本无法加载。
*   **清空浏览器缓存:** 有时浏览器会缓存旧的HTML文件,导致新的脚本没有被加载。尝试清空浏览器缓存或使用隐身模式访问页面。
*   **检查网络加载:** 使用浏览器的开发者工具(F12)查看“网络”选项卡,确认`MathJax-script`是否成功加载(HTTP状态码为200)。如果加载失败,可能是CDN服务问题或网络连接问题。
*   **公式语法检查:** 确保您在内容中使用的数学公式语法(如LaTeX)是正确的,并且符合MathJax的解析标准。
