JS随机调用指定函数的方法

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
