Open Menu Item in new window

I have added few custom links in the Menu bar and the following script it added in custom scripts.

jQuery(‘#menu-item-677’).bind(‘click’, function(e) {
location.href = ‘http://mysite.com/merchant’;
});

This is working fine. But the only problem is, the page is opening in the same tab/window.

I wanted to open the link in a new tab/window. What attribute/code, shall I add to open these menu links in new window.
The url attribute which we generally use is :-

target = “_blanK”

Please provide details
