window.open external link opening in new tab

Question

So I have a confirmation dialog box that opens when button is clicked, but window.open in javascript opens it in new tab. I tried lot of things like _self, _top but it doesn't work. Is there any way I can open this in same tab/page.

Here is the code:

<a href="http://www.google.com/" class="sample"></a>

JAVASCRIPT

 $('.sample').on("click", function (e)
    {
        var link = this;
        e.preventDefault();

        $( "#ConfirmDialog" ).dialog(
        {
            resizable: false,
            width: 300,
            buttons:
            {
                "Yes": function()
                {
                     window.open($(link).attr("href"));
                    $( this ).dialog( "close" );
                },
                Cancel: function()
                {
                    $( this ).dialog( "close" );
                }
            }
        });
    });

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")     
            },
    ....
});
