Don’t talk much
Call up SMS
window.location.href = 'sms://'
Start mobile wechat client
window.location.href = 'weixin://'
Call up your cell phone
window.location.href = 'tel://'
SMS if you need to specify the recipient and the content of the message
window.location.href = 'sms:' + phone + '?body=' + body
The phone is the receiver, and the body is the content of the SMS. Because there is only an Android, the IOS system is not tested
It’s about changing? Into & testing what you need
If you call a specific number
window.location.href = 'tel:' + phone
At this point, it may be useful to make a note.
