问题 I am trying a new functionality for my web site. I want to do simple navigation by hiding/showing <div> elements.

问题 When I navigate back using the browser back button in Chrome/ Firefox my website works just as expected (the same as it would if loaded without navigating backward). In Safari after navigating back I can't get any 'on load' type event to fire whether the standard document ready or some hackaround found on here on StackOverflow.

问题 i have a AngularJS app with list of items and the detail of the item. If I do some changes in detail and I want to return to list , list is already created again via remote request.
