Evaluates an expression after a specified number of milliseconds has elapsed.

(在指定時(shí)間過后執(zhí)行指定的表達(dá)式)

Syntax:

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.

以下內(nèi)容沒抄任何人的,如果有雷同,估計(jì)不是你抄偶的就是巧合,嘿嘿.

setTimeout( alert("3秒種過去了"), 3000);//調(diào)用一個(gè)函數(shù),允許帶常量參數(shù)

<script language="Javascript">
//by zuoyang

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(shù)的setTimeout調(diào)用形式
          return z;
}

setTimeout( function(){ sum = Plus(x, y, z); }, 3000);/*除了可以帶變量參數(shù)還可以獲取返回值的setTimeout調(diào)用形式*/

</script>

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(zhí)行一次vCode.(Evaluates an expression each time a specified number of milliseconds has elapsed)
