Can get two cases: click on the button to trigger, gets the current time, if the time more than 11 points to change state (enter the page also get a, look have exceed the time limit) 2: write the timer, every once in a while whether the time more than 11 points, more than change state cost (performance), it is recommended to use the first method, the second's a waste of resources
