Why don"t self-closing script elements work?
📝 Why don't self-closing script elements work?
Hey there tech enthusiasts! 👋 Today, we're gonna delve into a confounding question: Why don't self-closing script elements work in browsers? 🤔 It's frustrating when something as seemingly simple as a self-closing script element causes issues, right? Don't worry, we've got your back! In this blog post, we'll tackle this problem head-on, provide easy solutions, and pave the way for smoother coding. Let's get started! 💪
The Mystery of Self-Closing Script Elements
Here's the deal. You might be familiar with the common practice of self-closing elements, such as <br /> tags, which are a time-saving way to avoid opening and closing tags. However, using self-closing syntax for script elements, like in the example below, doesn't work consistently:
<script src="foobar.js" /> <!-- self-closing script element -->But why, you might ask? 🤷♂️ Well, dear readers, it all comes down to the way browsers interpret HTML code. The HTML specification, which guides browsers in rendering web pages, simply does not support or recognize self-closing script elements.
In the example above, only the following traditional syntax is correctly recognized by browsers:
<script src="foobar.js"></script>Does This Break the Concept of XHTML Support?
A valid question indeed! 😉 However, this issue with self-closing script elements doesn't necessarily break the concept of XHTML support. XHTML, a stricter version of HTML, requires well-formed XML-style syntax. While self-closing elements are allowed in XHTML, they apply to certain predefined elements and not to script elements.
Easy Solutions to the Rescue! 🚀
Now that you understand why self-closing script elements don't work, here are some straightforward solutions to help you overcome this hurdle:
Opt for traditional syntax: Stick to the traditional way of writing script elements by opening and closing them explicitly, like this:
<script src="foobar.js"></script>Use a build tool or transpiler: If you're working with a build tool or a transpiler like Babel, it can automatically convert self-closing script elements into the correct syntax. Simply configure the tool to handle this for you, making your code cleaner and more browser-friendly.
