我在一个基本的 HTML/JavaSript 类中,我想不出一种方法(以及在哪里放置)一个由五个 bgcolors 组成的数组,并且“使用 stylize() 函数选择一种颜色来随机选择单元格背景”。我必须使用和编辑下面的代码。代码已经可以工作了,我只需要添加 bgcolors 数组并使用它来更改表格单元格 bgcolor。我是 HTML 和 JavaScript 的新手,任何帮助将不胜感激。先感谢您!
<html>
<head>
<title>HTML and JavaScript</title>
<link href="capstone.css" rel="stylesheet" type="text/css"></link>
<script>
var index = 0;
function stylize()
{
index++;
if (index > 20) index =1;
var s = "myStyle" + index;
var e = document.getElementById("MessageText");
e.className = s;
setTimeout("stylize()", 1500);
return;
}
function getRandomInt (min, max)
{
return Math.floor(Math.random() * (max - min + 1)) + min;
}
index = getRandomInt(1, 20);
</script>
</head>
<body onLoad="stylize()">
<table align="center" border="1" bordercolor="black">
<tr>
<td align="center">
<font size="3"><b>STYLE CLASS VIEWER</b></font>
</td>
</tr>
<tr>
<td align="center" height="100" width="400">
<div id="MessageText" class="myStyle1">
Hello World Wide Web!
<div>
</td>
</tr>
</table>
</body>
</html>
