Syntax:
iTimerID = window.setTimeout(vCode, iMilliSeconds [, sLanguage])
Parameters
| vCode |
Required.
Variant that specifies the function pointer or string that indicates
the code to be executed when the specified interval has elapsed. |
| iMilliSeconds |
Required. Integer that specifies the number of milliseconds. |
| sLanguage |
Optional. String that specifies one of the following values:
| JScript |
Language is JScript. |

setTimeout( alert("3秒種過去了"), 3000);//調用一個函數,允許帶常量參數

<script language="Javascript">

var x = 1;
var y = 2;
var z = 3;
var sum;
function Plus(a, b)
{
var z = 0;
var i = 0;
for (i = 0; i < arguments.length; i++)
{
z += arguments[i];
}
setTimeout( function() {alert(z);}, 6000); //可以帶變量參數的setTimeout調用形式
return z;

setInterval()的用法和setTimeout()是一樣的:
iTimerID = window.setInterval(vCode, iMilliSeconds [, sLanguage])
不同的是setTimeout()是一次性作用,而setInterval()是每隔iMilliSeconds就執行一次vCode.(Evaluates an expression each time a specified number of milliseconds has elapsed)
