在我的示例中，它将向您展示如何有争议地循环遍历数组直到停止.这只是给您一个有关如何执行延迟的想法.还会在实际显示该值时向您显示.

In my example, it will show you how to loop through an array contentiously until you stop. This is to just give you an idea on how you can do the delay. Also it shows you when the value actually got displayed.

我想说的是，您实际上可以从此计时器创建一个不错的实用程序，并将其用于多种用途，并且借助该实用程序，您可以避免重复大量代码.

I would say that you could actually create a nice utility from this timer, and use it for multiple purposes and with the utility it'll stop you from repeating large chunks of code.

JavaScript循环示例:

var body = document.body;
var splittedText = ["Hello", "World", "How", "Are", "You", "Today"];

loopThroughArray(splittedText, function (arrayElement, loopTime) {
    body.innerHTML += arrayElement+ ": " + loopTime+ "<br/>";
}, 1000);

function loopThroughArray(array, callback, interval) {
    var newLoopTimer = new LoopTimer(function (time) {
        var element = array.shift();
        callback(element, time - start);
        array.push(element);
    }, interval);

    var start = newLoopTimer.start();
};

// Timer 
function LoopTimer(render, interval) {
    var timeout;
    var lastTime;

    this.start = startLoop;
    this.stop = stopLoop;

    // Start Loop
    function startLoop() {
        timeout = setTimeout(createLoop, 0);
        lastTime = Date.now();
        return lastTime;
    }
    
    // Stop Loop
    function stopLoop() {
        clearTimeout(timeout);
        return lastTime;
    }
    
    // The actual loop
    function createLoop() {
        var thisTime = Date.now();
        var loopTime = thisTime - lastTime;
        var delay = Math.max(interval - loopTime, 0);
        timeout = setTimeout(createLoop, delay);
        lastTime = thisTime + delay;
        render(thisTime);
    }
}
