颜色变化的欢迎词

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<Script language="JavaScript">

var someText = "Welcome to www.7stk.com";	// the text
var aChar;
var aSentence;
var i=0;					// a counter

var colors = new Array("FF0000","FFFF66","FF3399","00FFFF","FF9900","00FF00"); // the colors
var aColor;					// the chosen color

function loadText()
{
	// randomly choose color
	aColor = colors[Math.floor(Math.random()*colors.length)];

aChar = someText.charAt(i);
	if (i == 0)
		aSentence = aChar;
	else
		aSentence += aChar;

// 50 iterations max.
	if (i < 50)	i++;
	
	// For IE
	if (document.all)
	{
		textDiv.innerHTML= "<font color='#"+aColor+"' face='Tahoma' size='5'><i>"+aSentence+"</i></font>";
		setTimeout("loadText()",100);
	}
		
	// For Netscape Navigator 4
	else if (document.layers) 
	{
		document.textDiv.document.write("<font color='#"+aColor+"' face='Tahoma' 								size='5'><i>"+aSentence+"</i></font>");
		document.textDiv.document.close();
		setTimeout("loadText()",100);
	}
		
	// For other
	else if (document.getElementById)
	{
		document.getElementById("textDiv").innerHTML = "<font color='#"+aColor+"' 			face='Tahoma'size='5'><i>"+aSentence+"</i></font>";
		setTimeout("loadText()",100);
	}
}
</SCRIPT>
<div id="textDiv"></div>

第二步：把<body>中的内容改为：
<body  onLoad="loadText()">
