setTimeout()及 setInterval()的使用（转）
Evaluates an expression after a specified number of milliseconds has elapsed.
(在指定时间过后执行指定的表达式)
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. VBScript Language is VBScript. JavaScript Language is JavaScript.
Return Value
Integer. Returns an identifier that cancels the evaluation with the clearTimeout method.

以下内容没抄任何人的,如果有雷同,估计不是你抄偶的就是巧合,嘿嘿.
-------------------------------------------------------------------
setTimeout( alert("3秒种过去了"), 3000);//调用一个函数,允许带常量参数
-------------------------------------------------------------------
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); //可以带变量参数的setTimeout调用形式
return z;
}
setTimeout( function(){ sum = Plus(x, y, z); }, 3000);/*除了可以带变量参数还可以获取返回值的setTimeout调用形式*/
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); //可以带变量参数的setTimeout调用形式
return z;
}
setTimeout( function(){ sum = Plus(x, y, z); }, 3000);/*除了可以带变量参数还可以获取返回值的setTimeout调用形式*/
setInterval()的用法和setTimeout()是一样的:
iTimerID = window.setInterval(vCode, iMilliSeconds [, sLanguage])
