(在指定時間過后執行指定的表達式)

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

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;
}

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

</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就執行一次vCode.(Evaluates an expression each time a specified number of milliseconds has elapsed)
