How to Find JS in HTML

If you're looking for JavaScript code in your HTML, there are a few ways to find it:

1. View Page Source

The easiest way to find JavaScript code in your HTML is to view the page source. In most web browsers, you can right-click on the page and select "View Page Source" or "View Source". This will open the HTML code in a new window or tab.

To find JavaScript code, you can use the browser's search function (usually CTRL+F or CMD+F). Type "script" or ".js" (without the quotes) into the search box and press enter. The browser will highlight all instances of the search term in the source code.

If you find a script tag with a "src" attribute, that means the JavaScript code is in an external file. You can click on the link in the "src" attribute to view the JavaScript code.

<script src="example.js"></script>

2. Inspect Element

If you want to find JavaScript code that's generated dynamically or inserted into the page after it loads, you can use the browser's "Inspect Element" tool.

To do this, right-click on the element that you suspect has JavaScript code attached to it and select "Inspect" or "Inspect Element". This will open the browser's developer tools and highlight the relevant HTML code.

You can then look for script tags or inline JavaScript code in the HTML. If you find an inline script tag, the JavaScript code will be inside the tag.

<div onclick="alert('Hello, world!')">Click me!</div>

3. Search the Code

If you have access to the source code of the website or web application, you can search the code for JavaScript code manually. This can be time-consuming, but it's useful if you want to find all instances of JavaScript code in the codebase.

You can use a text editor or an IDE with search capabilities to search for "script" or ".js" (without the quotes) in all files in the codebase.

Using Highlight.js for Syntax Highlighting

If you want to display the JavaScript code on your website or blog with syntax highlighting, you can use a library like Highlight.js.

To use Highlight.js, you need to include the library's CSS and JavaScript files in your HTML code. You can download the files from the Highlight.js website or use a CDN.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/styles/default.min.css">
<script src="https://cdn.jsdelivr.net/npm/[email protected]/highlight.min.js"></script>

Once you've included the library, you can wrap your JavaScript code in a "pre" tag with a "code" tag inside. Then, add the "language-javascript" class to the "code" tag.

<pre><code class="language-javascript">
// JavaScript code goes here
</code></pre>

When you load the page, the JavaScript code will be displayed with syntax highlighting.

Overall, finding JavaScript code in HTML can be done in a few different ways, depending on your needs. Using Highlight.js can also make it easier to display JavaScript code with syntax highlighting on your website or blog.
