Do I have to write JS on the H5 page?

H5 pages usually require JavaScript to achieve interactive and dynamic effects, but static pages do not. Alternatives include CSS animation, server-side rendering, and JS-free frameworks, but these methods have limitations. Therefore, it is crucial to learn and apply JavaScript to fully realize the potential of H5.

Do H5 pages have to write JS? The answer is: Not necessarily, but usually it is required.

This question is wonderful. It seems simple, but it actually has a hidden mystery. Many newbies will think that the H5 page is made up of a bunch of HTML tags, but it is not. HTML is just a skeleton, CSS is the appearance, and JavaScript is the soul, giving page dynamic interaction and flexibility. You can make a static H5 page with only HTML and CSS, just like a beautiful e-book. It looks good, but lacks interaction, and the experience is far from the bottom of it.

Think about it, a simple form submission, a cool animation effect, and a button that responds to user clicks, all of which require JavaScript to implement. Without JavaScript, your H5 page may be just a beautiful static page, unable to achieve any user interaction, and it will lose many H5 advantages.

Of course, if you just want to make a simple display page with the content fixed and no interaction required, then you can really not write JavaScript. For example, a simple product promotion page only needs to display some pictures and text, and at this time you can only use HTML and CSS to complete it. But this kind of scenario is relatively rare, after all, the power of H5 lies in its interactivity.

Now, let's take a deeper look. Assuming you really want to avoid JS, what can you do? You may consider some alternatives, such as:

• Using CSS animation: CSS3 provides powerful animation functions, which you can use to implement some simple animation effects and reduce your dependence on JavaScript. However, the complexity and expressiveness of CSS animation are far less than that of JavaScript animation library. CSS animation is not capable of complex animation effects.
• Server-side rendering: If you need some dynamic content, you can generate the content on the server and output it directly to HTML. But this will increase the burden on the server and will be more troublesome to maintain. And this approach still fails to achieve real client interaction.
• Using JS-free framework: Some H5 page building tools, such as some simple static site generators, can help you generate HTML pages that do not depend on JS, but their functionality will be very limited.

However, these methods have their limitations. CSS animation can only achieve simple animation effects, server-side rendering increases the burden on the server, while the functions without JS framework are very limited. So, unless your H5 page is extremely simple, JavaScript is almost always needed for interactive and dynamic effects.

Finally, I want to emphasize that JavaScript is not a disaster. Only by learning JavaScript and using it proficiently can we truly realize the potential of H5 and create a better user experience. Rather than tangling with how to avoid using JavaScript, learn how to use it better. After all, a good H5 page, JavaScript is an integral part. Remember, you can only get twice the result with half the effort by choosing the right tool. Don't be afraid to learn new technologies, it will take you further on the road to development.
