HTML DOM Anchor protocol Property

HTML Web Development Front End Technology

The HTML DOM Anchor protocol property is used to set or return the protocol of a link in the href attribute.

Following is the syntax to set the protocol property −

anchorObj.protocol = protocol_url

Above, protocol_url is the protocol of the URL. The values can be http, https, ftp, etc.

Following is the syntax to return the protocol property −

anchorObj.protocol
