Services with a widget for calling from a website to yii2?

Question

Yii

Is there a service to call from the documentation site for yii2 ?
The principle of operation is approximately the same. On the site, the administrator clicks, for example, on the tag with the client's phone number. This number is called immediately to the client. <a>

Answer 1

I don't know about the widget, but you can do it with jquery, for example. If only for the administrator, then even more so.
A match is searched on the page by phone mask and a handler is hung on it, which will initiate a call.
