javascript 間隔時間越來越長

Question

我在按鈕上為 animation 編寫了代碼

cta.addEventListener("mouseover", () => {
            setTimeout(() => {
                audio.play()
                audio.volume = .06;

                imgs[0].style.transform = "translate(0, 0)";
                
                setTimeout(() => {
                    imgs[2].style.transform = "translate(0, 0)";
                }, 150);
                
                setTimeout(() => {
                    imgs[1].style.transform = "translate(0, 0)";
                }, 200);
                
                setTimeout(() => {
                    imgs[5].style.transform = "translate(0, 0)";
                }, 250);
                
                setTimeout(() => {
                    imgs[3].style.transform = "translate(0, 0)";
                }, 300);
                setTimeout(() => {
                    imgs[4].style.transform = "translate(0, 0)";
                }, 600);
            }, 100);
        });

但這不是很愉快。

如何改進此代碼？ 只做一個 setInterval 並讓這個值隨着每次執行而增加？？

Answer 1

稍微好一點的代碼版本：

cta.addEventListener("mouseover", () => {
    setTimeout(() => {
        audio.play()
        audio.volume = .06;

        imgs[0].style.transform = "translate(0, 0)";
        transformImage(imgs[2], 150);
        transformImage(imgs[1], 200);
        transformImage(imgs[5], 250);
        transformImage(imgs[3], 300);
        transformImage(imgs[4], 600);
    }, 100);
});

function transformImage(img, interval) {
    setTimeout(() => {
        img.style.transform = "translate(0, 0)";
    }, interval);
}

進一步改進：

cta.addEventListener("mouseover", () => {
        setTimeout(() => {
            audio.play()
            audio.volume = .06;

            imgs[0].style.transform = "translate(0, 0)";
            let offset = 150;
            imgs.forEach(img => transformImage(img, offset+=50));
        }, 100);
    });
    
    function transformImage(img, interval){
            setTimeout(() => {
                img.style.transform = "translate(0, 0)";
        }, interval);
    }

我能看到的唯一改進方法是使用 for 循環：

 cta.addEventListener("mouseover", () => { setTimeout(() => { audio.play() audio.volume =.06; let times = [0, 200, 150, 300, 600, 250] times.forEach(function(let idx in times) { setTimeout(() => { imgs[idx].style.transform = "translate(0, 0)"; }, times[idx]); } }, 100);) });
