How can I make a website button open up an SMS compose to a phone number?
提问by Andrew
I've found solutions that make it so that when you click a button on a website, it links to a phone number and the users phone will open up the dialer with that number pre-filled like so.
我找到了这样的解决方案，当您单击网站上的按钮时，它会链接到一个电话号码，而用户的电话将打开拨号器，并像这样预先填充该号码。
What I want to do instead is open up the users sms application in "compose message" mode to that specific number. Is there any way to do this? I've tried the following approach, but it doesn't work on Android:
我想要做的是在“撰写消息”模式下打开用户短信应用程序到该特定号码。有没有办法做到这一点？我尝试了以下方法，但它不适用于 Android：

The general format is:
<a href="sms:+919999999999?body=Hello World!">Link</a>
一般格式为：
<a href="sms:+919999999999?body=Hello World!">Link</a>
You could also add multiple numbers to the recipient list:<a href="sms:+919999999999,+919999999990?body=Hello World!">Link</a>
您还可以向收件人列表添加多个号码：<a href="sms:+919999999999,+919999999990?body=Hello World!">Link</a>
I found this to be working on my Android device, as well:<a href="sms://+919999999999?body=Hello%20World!">Single recipient and encoded body</a>
我发现这也适用于我的 Android 设备：<a href="sms://+919999999999?body=Hello%20World!">Single recipient and encoded body</a>
A Small Demo:
一个小演示：

text-align: center;
}
a {
font-size: 24px;
}
code {
font-size: 18px;
line-height: 26px;
white-space: normal;
word-break: break-word;
background-color: lightgray;
padding: 5px;
border-radius: 4px;
}
h1 {
margin-bottom: 5%;

As mentioned in the article the support depends on the platform and the SMS app, some work while others don't.
正如文章中提到的，支持取决于平台和 SMS 应用程序，有些有效，有些则无效。
Also avoid using it if there's no dynamic component involve for device detection; since on desktop the link will do absolutely nothing.
如果没有涉及设备检测的动态组件，也避免使用它；因为在桌面上，链接绝对不会做任何事情。
