Answer 1

You can pass additional parameters to window.open in doing this MOST browsers will pop open in new window instead of adding another tab.

W3 Schools Window open() Method

window.open(URL,name,specs,replace)

Example:

window.open("http://www.w3schools.com", "thisIsMyWindowName", "height=200,width=200");

if you do not want to specify window height and width just pass specs as a blank string.

window.open("http://www.w3schools.com", "thisIsMyWindowName", "");
