How to display JavaScript code in different environments

In today's era, JavaScript has become a widely used programming language. With the continuous promotion of Internet applications, more and more people are paying attention to JavaScript programming and how to display JavaScript code accurately and effectively. In this article, we will discuss some basic ways to display JavaScript code in different environments.

1. Use code boxes

Placing code in code boxes is one of the most common ways to display JavaScript. Code boxes can be created using HTML and CSS as shown below:

<pre class="brush:php;toolbar:false"><code>
// 在这里输入JavaScript代码
</code>

In the above code, the <code><pre class="brush:php;toolbar:false">&lt;/code&gt; tag is used to predefine formatted text (i.e. code). Then, enter the JavaScript code in the &lt;code&gt;&lt;code&gt;&lt;/code&gt; tag. Using this approach ensures that your code retains its original formatting and is easy to read when displayed in a browser. &lt;/p&gt; &lt;ol start=&quot;2&quot;&gt;&lt;li&gt;Using Code Highlighting&lt;/li&gt;&lt;/ol&gt; &lt;p&gt;Code highlighting is a technique that distinguishes keywords and operators in code with different colors. This technique is very helpful for reading long codes. JavaScript code highlighting can be set up using various online editors and other third-party libraries. Here's an example: &lt;/p&gt; &lt;div class=&quot;code&quot; style=&quot;position:relative; padding:0px; margin:0px;&quot;&gt;&lt;pre class=&quot;brush:php;toolbar:false&quot;&gt;&lt;link rel=&quot;stylesheet&quot; href=&quot;//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.12.0/styles/default.min.css&quot;&gt; &lt;script src=&quot;//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.12.0/highlight.min.js&quot;&gt;&lt;/script&gt; &lt;script&gt;hljs.initHighlightingOnLoad();&lt;/script&gt; &lt;pre class=&quot;brush:php;toolbar:false&quot;&gt;&lt;code class=&quot;javascript&quot;&gt; // 在这里输入JavaScript代码 &lt;/code&gt;</pre></pre><div class="contentsignin">Copy after login</div></div> <p>In the code above, the <code><link> element and the <code><script> element reference the highlight.js library, and<code>hljs.initHighlightingOnLoad() The function initializes the highlighting code. Finally, JavaScript can be highlighted in the browser by adding <code>javascript to the class attribute of the <code><code> tag.

3. Using a text editor

Although a text editor is not a way to display JavaScript code directly in the browser, it is still a way to edit and display the code. A very common tool. For beginners, there are some popular text editors like VS Code, Sublime Text, Atom, and many more. These editors have rich JavaScript editing and debugging capabilities, making development faster and more convenient.

4. Embed code in a blog or online article

If you are writing a blog or online article and want to embed JavaScript code, there are many online tools such as CodePen and JSFiddle. In addition to being used to demonstrate code, these tools can create and edit complete projects, as well as share and collaborate with others, especially on the Internet.

In short, the methods mentioned above are suitable for displaying JavaScript code in browsers and on the Internet. So, choosing this method will not only help you master JavaScript programming skills more effectively, but also share and collaborate with your friends on the Internet.
