JavaScript compiled a timer, a javascript Timer
A timer is written in JavaScript.
Design Philosophy:
1. Use the Date () object to continuously obtain time points;
2. Subtract the milliseconds between the two time points to calculate the time difference;
3. accumulate the time difference so that the timing can be accurate.
Ps:
If this method is not found on the i

Tutorial
A timer can be used to automate a task after a user has done nothing, and any task and user action that activates the card page starts the timer, and the timer stops when the task goes. Each card can have only one timer, and a timer can only trigger one task. The sy
The timer control is placed in updatepanl, which is different from the outside. For example, if the interval attribute of the timer control is set to 10000, if the return job takes 2 seconds, it takes 10 seconds to start the timer after the return, that is, 12 seconds to start returning the job. If it is placed outside, it is different. When the return starts to

These days have been engaged in an early warning monitoring daemon, the other is done, the most tangled is that the daily fixed time to execute the problem, the main reason for the tangle is not clear the method of the timer, Timer.schedule (timertask task,long l1,long L2 ), it is clear that the task is executed after the L1 time period and then executed once per L2 time,But Timer.schedule (timertask task,date l1,long L2), just started not to be too c
In a HTML5 project to use the timer, I learned a bit, and you share the experienceA method needs to be used: SetInterval ("Ballmove ()", 1000);Means to execute the Ballmove () method once per secondwhere he can use it, it will require the small partners to play with their imagination.
