随鼠标的彩色字符

鼠标移动即可见到效果!

欢迎光临 javascript 精彩世界 !

脚本说明:
第一步:把如下代码加入<head>区域中
<STYLE>.spanstyle {
	COLOR: #0066ff; FONT-FAMILY: 隶书; FONT-SIZE: 14pt; FONT-WEIGHT: normal; POSITION: absolute; TOP: -50px; VISIBILITY: visible
}
</STYLE>

第二步:把如下代码加入<body>区域中
<SCRIPT language=javascript>
	var message="欢  迎  光  临  javascript 精 彩 世 界  !";
	var x,y;
	var step=12;
	var flag=0;

message=message.split("");
	var xpos=new Array();
	for (i=0;i<=message.length-1;i++) {
		xpos[i]=-50;
	}

var ypos=new Array();
	for (i=0;i<=message.length-1;i++) {
		ypos[i]=-50;
	}

function handlerMM(e) {
		x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX+10;
		y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY;
		flag=1;
	}

function makesnake() {
		if (flag==1 && document.all) {
    			for (i=message.length-1; i>=1; i--) {
   				xpos[i]=xpos[i-1]+step;
				ypos[i]=ypos[i-1];
    			}
			xpos[0]=x+step;
			ypos[0]=y;

for (i=0; i<=message.length-1; i++) {
    				var thisspan = eval("span"+(i)+".style");
    				thisspan.posLeft=xpos[i];
				thisspan.posTop=ypos[i];
				thisspan.color=Math.random() * 255 * 255 * 255 + Math.random() * 255 * 255 + Math.random() * 255;
    			}
		}
		else if (flag==1 && document.layers) {
    			for (i=message.length-1; i>=1; i--) {
   				xpos[i]=xpos[i-1]+step;
				ypos[i]=ypos[i-1];
    			}
			xpos[0]=x+step;
			ypos[0]=y;

for (i=0; i<message.length-1; i++) {
    				var thisspan = eval("document.span"+i);
    				thisspan.left=xpos[i];
				thisspan.top=ypos[i];
				thisspan.color=Math.random() * 255 * 255 * 255 + Math.random() * 255 * 255 + Math.random() * 255;
			}
		}
	}
</SCRIPT>

<SCRIPT language=javascript>
	for (i=0;i<=message.length-1;i++) {
    		document.write("<span id='span"+i+"' class='spanstyle'>");
		document.write(message[i]);
    		document.write("</span>");
	}

if (document.layers) {
		document.captureEvents(Event.MOUSEMOVE);
	}
	document.onmousemove = handlerMM;
</SCRIPT>

<SCRIPT language=javascript>
	function pageonload() {
		makesnake();
		window.setTimeout("pageonload();", 2);
	}
</SCRIPT>

第三步:把<body>改为
<body bgcolor="#fef4d9" onload=javascript:pageonload()>
