我正在嘗試迭代圖像數(shù)組，單獨(dú)顯示每個(gè)圖像并使用按鈕移至下一個(gè)圖像。但是，當(dāng)單擊按鈕時(shí)，它會移動到下一個(gè)圖像，但在第二個(gè)圖像之后，它不會移動到第三個(gè)圖像，等等任何人都可以找到循環(huán)卡住的地方嗎？function changeImage() { var imageArray = ["/Users/rate/images/images/practice/sun1.jpg", "/Users/rate/images/images/practice/sun2.jpg", "/Users/rate/images/images/practice/sun3.jpg", "/Users/rate/images/images/practice/sun4.jpg"] var currentImage = 0; currentImage += 1; if (currentImage >= imageArray.length) { currentImage = 0; } document.getElementById("mainImage").src = imageArray[currentImage]}<!DOCTYPE html><html><head> <title> App Icons? </title> <link rel="stylesheet" type="text/css" href="/Users/Website/css/mainstyle.css"> <script type="text/javascript" src="/Users/rate/js/main.js"></script></head><body class="body"> <div> <div> <hr> <div class=topbar> <h1> Do you find this App Icon aesthically pleasing</h1> </div> <hr> <div id=displayedImage> </div> <img src="/Users/rate/images/images/practice/sun1.jpg" id="mainImage" /> <div id=answer> <label> Strongly Agree </label> <label><input type="radio" name="answer" value="1" required><span>1</span></label> <label><input type="radio" name="answer" value="2" required><span>2</span></label> <label><input type="radio" name="answer" value="3" required><span>3</span></label> <label><input type="radio" name="answer" value="4" required><span>4</span></label> <label><input type="radio" name="answer" value="5" required><span>5</span></label> <label> Strongly disagree</label> <hr> </div> <input type="button" onclick="changeImage()" value="I am complete">
如何獲取數(shù)組上的第二個(gè)索引
料青山看我應(yīng)如是
