Code to preserve time and play/pause state when switching tabs

gistfile1.js

var lastT = 0;
var downT = 0;
var lastState = "unknown";

wistiaEmbed.bind("timechange", function(t) {
  lastT = t;
});

wistiaEmbed.bind("down", function() {
  downT = lastT;
});

wistiaEmbed.bind("up", function() {
  if (downT > 0) {
    wistiaEmbed.time(downT);
    if (lastState === "playing") {
      wistiaEmbed.play();
    } else {
      wistiaEmbed.pause();
    }
  }
});

// this line is pseudo-code
$("#my_tab").beforeLoseFocus(function() {
  lastState = wistiaEmbed.state();
});
