HTML Autocomplete sms code

• 5 devs liked it

Learn how to help the used showing one-time-password codes in HTML.

I’m sure you’ve seen these around, you have to enter an SMS code, and it pops up in the input field.

But did you know this is super easy to achieve in HTML? Yes, HTML, no fancy JavaScript, nothing!

What I’m talking about looks like this:

HTML Structure permalink

For this to work we need a specific input element with some attributes:

input type="text" name="token" inputmode="numeric" pattern="1" autocomplete="one-time-code" />

As you can see, we render a numeric input to show the number keyboard on mobile devices. But the proper magic is in the autocomplete field. The one-time-code is used to help the user.

Note: The are multiple autocomplete values we can use: Read more on MDN

You can find the full HTML structure on the following Codepen.

Browser support permalink

Unfortunately, this will only work in Safari and iOS at the moment. The autocomplete, in general, has pretty good support.

Send SMS Messages From a Link with HTML

Links have been around since the dawn of the internet. While HTML anchor tags are most often used to link pages, there are also other possibilities including launching an email client and the Messages app on mobile devices.

This article explores sending custom SMS messages using simple HTML links.

Why Create SMS Links?

There are several reasons for creating SMS links for users to click on. One might be to sign up or opt into a newsletter to receive regular updates about your website or the services you offer. Another could be to notify potential or existing customers of new products, coupons, or upcoming events.

Generally, the goal is to connect with your users or customers so you can convey information to them much easier.

These links aren’t necessarily limited to just websites. SMS links will also work within emails, online profiles that accept HTML syntax, or even native applications that support clickable links.

The Syntax

Creating SMS links is a pretty simple task. Links for SMS are no different. In its simplest form, launching the Messages app from your device looks like this:

That’s it! This link alone will launch your Messages app. But it’s not very helpful. Your users will not know what to do once the application has launched.

You’ll want to give them some direction, and we can do so by adding in the phone number you want them to send a message to:

The Messages app will launch with the phone number pre-populated with +2125551212.

This is an invalid phone number for testing purposes. Make sure you’re using a phone number that’s linked to you or your services so you receive them properly from your users.

Creating a Message Body

The more popular platforms include the ability to add a pre-populated custom message body, as well! You can do so with the following syntax:

Notice that the body attribute is URL encoded. Most server-side languages have a method for encoding text automatically, so make sure to use it. If you’re writing only HTML code, then you can use this URL Encoder/Decoder.

Device Support

Most mobile devices will launch the Messages app that comes out of the box with the device. However, there are some caveats:

• iOS, Android & Opera Mobile: Most OS versions on both platforms have full support for the phoneno and body attributes.
• webOS & IE Mobile: phoneno and body attributes not supported on any versions.

Certain platforms or operating systems may not support all features, so make sure you thoroughly test your links on the platforms you plan on supporting.

Best Practices

Here are a few guidelines you should following when introducing SMS messaging options:

• Make your process clear. Add a disclaimer near the link explaining exactly what the link will do. How it will open the messaging app and populate the fields automatically. Where the SMS message is going. What they’re signing up for. What will happen after they send an SMS message. The more details you give to your users, the more likely they are to click the link and submit a message.
• Make sure to note to your users that standard messaging and data rates may apply when submitting SMS messages. There are a lot of unlimited plans with the various mobile networks nowadays, but that doesn’t mean that everybody is on them.
• Once the user sends an SMS message, their phone number will be shared with your service. Make sure to make this apparent in your Privacy Policy or within a disclaimer near the SMS link.

Conclusion

That’s all there is to it! Providing SMS links for your users or customers can open up a whole new world of opportunities for communication with them.

Send a SMS Text From A Link

While tags are most often used to link pages, most developers are aware that they can prompt an eMail by using the mailto: protocol. Few developers are aware that it’s also possible to initiate a phone call from a web page using tel: , and almost no-one is aware that you can do the same thing with SMS messages.

The basic format of the link is very simple:

Some systems (Android, Symbian, webOS) don’t allow a number, to avoid potentially expensive overages on international messages.

Finally, a precomposed (and percent encoded) message can be included in the link, at least for some systems:

If you’re on a supported mobile platform, you can try clicking this link: Send a SMS. The number is in a fictional Hollywood movie area code, so it won’t actually send a message to anyone.

A Note On Privacy

It’s worth pointing out that a sent SMS message will share the user’s phone number; the site’s use of this information should be addressed in a separate privacy statement.

Challenges

You can’t use connection type or screen size to determine if your site is communicating to a mobile phone with any kind of predictability. Currently, the only reliable method is device detection, via a system like WURFL or PHP mobile detect. With that in place, you could wrap the link in context-aware code:

Further detection refinement would allow you to customize the SMS link feature for different phone systems.
