(sTitle, sURL, "");
parameter
sURL: Collection of full links to the website page
sTitle: The name of the page of the collection site
Example:
<a href='#' onClick="javascript:('name','','');">Save this site</a>
Note here that the parameter order of the addPanel function is exactly the opposite of addFavorite.
The second method:
Add rel="sidebar" attribute on the link
Example:
<a href= title="name" rel="sidebar">Save this site</a>
Note: The title attribute here is the name of the collection website page.
