title: How do identify whether the window opened is a pop up or a tab?
body: <p>I have been facing a problem.I am able to open a window using window.open method.If I specify the height and width of the window,it opens as a pop up window.If no parameters is given for height or width,then it opens in a new tab.</p>
  
  <p>Is there any property through which I can determine window opened was a pop up or a new tab?</p>
  
  <p>Thank you
