Pass text to iMessage via html?

Question

JavaScript

Good afternoon, you need to solve the following problem:
- when you click on the button on the site, call iMessage;
- transfer the prepared text to the message body;

It is desirable to use only html and javascript, if at the moment it is impossible to solve the problem in this way, then tell me how to really do it.
Thank you.

According to the specification , it is possible to open an iMessage with an empty message but a number inserted.

<a href="sms:">Launch Messages App</a>
<a href="sms:1-408-555-1212">New SMS Message</a>
