Question

So I'm trying to loop through this array and change an image source every few seconds. 所以我试图遍历这个数组并每隔几秒就改变一次图像源。 Right now I have an onload event calling a setTimeOut method which should change the image 5 seconds after the page has loaded I would think, but it is doing it instantly. 现在我有一个onload事件调用一个setTimeOut方法，该方法应该在页面加载后5秒更改图像，我会想，但它会立即执行。 What is the problem? 问题是什么？ Here is my code: 这是我的代码：

<html>
<head>
    <title>Ad Rotaror</title>
    <script type="text/javascript">
        var i = 0;
        var ads = new Array(4);
                  ads[0]='promo1.gif';
                  ads[1]='promo2.gif';
                  ads[2]='promo3.gif';
                  ads[3]='promo4.gif';
                  ads[4]='promo5.gif';

        function change()
        {
            if(i > 4)
                i = 0;

            document.images[0].src = ads[i];
            i++;
        }
    </script>
</head>
<body>
    <img src="promo1.gif" onload="setInterval(change(), 5000)" />
</body>
</html>

Answer 1

Change 'change()' to 'change'. 将'change（）'更改为'change'。 You are calling the function immediately. 您正在立即调用该函数。
