Javascript Window. Location in New Tab

window.open(' '_blank');

The second parameter is what makes it open in a new window. Don't forget to read Jakob Nielsen's informative article :)

You can even use

window.open(' "_blank") || window.location.replace(');

This will open it on the same tab if the pop-up is blocked.

This works for me on Chrome 53. Haven't tested anywhere else:

function navigate(href, newTab) {
   var a = document.createElement('a');
   a.href = href;
   if (newTab) {
      a.setAttribute('target', '_blank');
   }
   a.click();
}

with jQuery its even easier and works on Chrome as well

$('#your-button').on('click', function(){
       $('<a href="" target="blank"></a>')[0].click();    
})

Rather going for pop up,I personally liked this solution, mentioned on this Question thread JavaScript: location.href to open in new window/tab?

$(document).on('click','span.external-link',function(){
        var t               = $(this), 
            URL             = t.attr('data-href');        
        $('<a href="'+ URL +'" target="_blank">External Link</a>')[0].click();

    });

Working example.

We have to dynamically set the attribute target="_blank" and it will open it in new tab. document.getElementsByTagName("a")[0].setAttribute('target', '_blank')

document.getElementsByTagName("a")[0].click()

If you want to open in new window, get the href link and use window.open

var link = document.getElementsByTagName("a")[0].getAttribute("href");

window.open(url, "","height=500,width=500");

Don't provide the second parameter as _blank in the above.
