推荐方法pagecontainerbeforechange:https://jqmtricks.wordpress.com/2014/12/01/detect-back-navigation/

你需要听navigation事件和state.direction.

$(window).on("navigate", function (event, data) {
  var direction = data.state.direction;
  if (direction == 'back') {
    // do something
  }
  if (direction == 'forward') {
    // do something else
  }
});
