Use cookies:

set the cookie :

function setCookie(c_name,value,exdays)
{
  var exdate=new Date();
  exdate.setDate(exdate.getDate() + exdays);
  var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
  document.cookie=c_name + "=" + c_value;
}

Get the cookie:

function getCookie(c_name)
{
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1)
  {
  c_start = c_value.indexOf(c_name + "=");
  }
if (c_start == -1)
  {
  c_value = null;
  }
else
  {
  c_start = c_value.indexOf("=", c_start) + 1;
  var c_end = c_value.indexOf(";", c_start);
  if (c_end == -1)
  {
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start,c_end));
}
return c_value;
}

You could use the window’s name window.name to store the information. This method is often used to modify the name of a window, after the window has been created. It only works as long as the same window/tab is used.

For more info: https://developer.mozilla.org/en-US/docs/Web/API/Window.name

Like jQuery, jQuery attached to window and work as a global variable that can access from any window you can do something like...

Use PHP or JSP session and then retrieve your value in any page using AJAX.

You should have an ajax request to initialize your value first. Then you should set/update/read your boolean value accordingly using AJAX.

Let me know if you need details.
