@H_502_0@本文实例讲述了JS随机调用指定函数的方法。分享给大家供大家参考。具体如下：

@H_502_0@本代码通过随机定时器调用指定函数，可达到间隔随机时间之行指定的函数的目的

<div class="jb51code">
<pre class="brush:js;">
function randRange(data) {
var newTime = data[Math.floor(data.length * Math.random())];
return newTime;
}
function toggleSomething() {
var timeArray = new Array(200,300,150,250,2000,3000,1000,1500);
// do stuff,happens to use jQuery here (nothing else does)
$("#Box").toggleClass("visible");
clearInterval(timer);
timer = setInterval(toggleSomething,randRange(timeArray));
}
var timer = setInterval(toggleSomething,1000);
// 1000 = Initial timer when the page is first loaded
