The Window object has two main timing methods, settimeout and Setinteval, whose syntax is essentially the same, but the completed functionality differs.
The SetTimeout method is the timer program, which is what to do after the time. Just finish it.
The SetInterval method is to indicate that an operation is repeated at a certain time interval.
If you implement the function of Setinerval with settimeout, you need to call yourself in the program you are executing. If you want to clear the counter you need to invoke different cleanup methods depending on the method you are using:
1) settimeout (expression, delay time)
At execution time, after the specified time is delayed, the expression is executed once, remembering that the number is once
The effect of displaying random number with automatic change realized by settimeout
<script>
Window.onload=sett;
function Sett ()
{
Document.body.innerhtml=math.random ();
settimeout ("Sett ()", 500);
}
</script>
<body>
</body>
2) setinterval (expression, interaction time)
is not the same, it executes an expression once at a specified time from loadingAutomatic changes with setinterval to display the effect of random numbers:
