SetTimeout and SetInterval instance codes and differences

Document with its own method:
Loop execution: var Timeid = Window.setinterval ("Method name or method", "delay"); Window.clearinterval (Timeid);
Timed execution: var tmid = Window.settimeout ("Method name or method", "delay"); Window.cleartimeout (Tmid);
An example is provided:

<script type= "Text/javascript Tutorial" >
Loop execution, execute once every 3 seconds Showalert ()
Window.setinterval (function () {
Showalert ("AAAAA");
}, 3000);
function Showalert (mess)
{
alert (mess);
}
Timed execution, 5 seconds to execute Showalert ()
Window.settimeout (function () {
Showalert ("bbbbbb");
},5000);
</script>

<script type= "Text/javascript" >
Loop execution, execute once every 3 seconds Showalert ()
Window.setinterval (Showalert, 3000);
function Showalert ()
{
Alert ("AAAAA");
}
Scheduled execution, 5 seconds to execute show ()
Window.settimeout (show,5000);
Function Show ()
{
Alert ("BBB");
}
</script>

SetTimeout and setinteval Their syntax is essentially the same, but the complete function is different.

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:

For example: Tttt=settimeout (' Northsnow () ', 1000);

Cleartimeout (TTTT);

Or:

Tttt=setinterval (' Northsnow () ', 1000);

Clearinteval (TTTT);

Give an example:

<div id= "Liujincai" ></div>
<input type= "button" name= "Start" value= "Start" onclick= ' Startshow ' (); ' >
<input type= "button" name= "Stop" value= "Stop" onclick= "Stop ();" >
<script language= "JavaScript" >
var intvalue=1;
var timer2=null;
function Startshow ()
{
liujincai.innerhtml=liujincai.innerhtml + "&nbsp;" + (Intvalue + +). toString ();
Timer2=window.settimeout ("Startshow ()", 2000);
}
function Stop ()
{
Window.cleartimeout (TIMER2);
}
</script>

Or:

<div id= "Liujincai" ></div>
<input type= "button" name= "Start" value= "Start" onclick= " Timer2=window.setinterval ("Startshow ()");//startshow (); ' >
<input type= "button" name= "Stop" value= "Stop" onclick= "Stop ();" >
<script language= "JavaScript" >
   var intvalue=1;
   var timer2=null;
   function startshow ()
   {
      Liujincai.innerhtml=liuj incai.innerhtml + "&nbsp;" + (Intvalue + +). toString ();
  }
   function Stop ()
   {
      window.clearinterval (timer2);
  }
</script>
