I often come across tutorials about building forms on the web. In spite of all the newfangled techniques and frameworks we now have to perform actions on web pages, the trusty old HTML form still has its place.
Hint, it involves HTML forms.
Which led me to wonder how many people really know about the different attributes that come baked in with HTML form elements. For example, the
Hang on, I can almost hear some of you saying, of course you know about them, you just typed
<input type="text"> for the millionth time yesterday.
And being the annoying person that I am, I’m very tempted to reply, well actually… the default
type attribute for
text and it would still work and validate even if you didn’t include it.
Yes, my friends, some HTML attributes have default values (as does all CSS, FYI).
There is no harm in including
type="text", and some people might even prefer to have it there, for reasons, and that’s fine.
This is just a gentle reminder in a world where people seem to be searching for all manner of ways and means to shave bytes, that default values don’t really have to be there.
Same goes for the
<button> element. The default type is
submit, which means if you had a vanilla HTML form like so:
<form action="/login"> <label for="username">Username</label> <input name="username" id="username"> <label for="password">Password</label> <input name="password" type="password"> <button>Login</button> </form>
And you clicked the button, or pressed the Enter key, your form would submit to /login. Guess what? The
method attribute on
<form> elements also has a default value, which is
Please don’t submit any sensitive information, like a password via the form’s
GET method because it becomes visible in the URL. Go ahead, throw the above form into a blank HTML file and try it. Using
POST will send the form data in the body of the HTTP request.
So if you wanted a button to do things other than submit a form, you can always use
<button type="button">, which gives you a clickable button that does… nothing. So you can attach whatever event listeners you like to it and make it trigger whatever you want.
I’ve come across tutorials for frameworks that were great at explaining the framework bit of things, but had shockingly nested
Say you want to have a character limit on your comments, which are input via a
<textarea>. You can use the
maxlength attribute. The browser will prevent any further input past the specified character length.
Or if you’d like your users to input comments that are longer than just a smiley face. You can use the
minlength attribute. Depending on the browser you’re using, it is a slightly different user experience but try submitting the form with less than 10 characters.
This is not a rant at the state of the web today (okay, maybe just a little bit). Rather, I want this to be an invitation to explore and discover which of these many wonderful attributes are most useful to you.
Then use them.
They are fully compatible with the framework of your choice.
Especially to all who are either hearing of these attributes for the first time, or never got around to using them.
So, at the risk of sounding like some grumpy old person yelling “get off my lawn” at the cool kids, I just want to end off with a quote from one of my esteemed seniors from a previous company.
The best code is the code not written.
Cheers, my friends. 🥃
