title: How do I open the previous active tab when returning from a new html page
body: <p>How do I return back to the previous active tab if I am moving back from another html page? </p>
  
  <p>I am having 5 tabs and within content of each tab there are links to another set of html pages. For example I am having a page called 'school.html' and it has 5 tabs. In tab 2 content (it shows individual student details) I am having a link to "Add new student" to a new page named addNewStudent.html. <br>
  After adding a new student in addNewStudent.html, I need to automatically comeback to original page with tabs (window.location = 'school.html'). So how to make tab 2 active showing the tab 2 content (student details).</p>
