You wanted to access the root document of server www.google.com, which is done using the url https://www.google.com/. You provided a relative url for document www.google.com instead.

Keep in mind that window.open accepts both relative and absolute urls, so it can't assume you left out https:// as it does when you use www.google.com in the address bar.

Maybe an example will help. Say the current page is http://www.example.com/dir/foo.html.

• window.open("popup.html", "_blank") opens
  http://www.example.com/dir/popup.html.
• window.open("www.google.com", "_blank") therefore opens
  http://www.example.com/dir/www.google.com.

The browser has no way of knowing you actually wanted https://www.google.com/ when you said you wanted http://www.example.com/dir/www.google.com since the latter could be valid.

You need to use the name attribute:

window.open("https://www.youraddress.com","_self")

Edit: Url should be prepended with protocol. Without it tries to open relative url. Tested in Chrome 59, Firefox 54 and IE 11.

Use window.open():

<a onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');">
  Share Page
</a>

This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

To change the current page's url, simply set window.location to the new url

$('.sample').on("click", function (e) {
    ....
            "Yes": function() {
                window.location = $(link).attr("href")     
            },
    ....
});

I have answered in the comments, but since this is what you are looking for, I'm adding it as an answer too.
