请各位大神帮忙看看，代码一样为啥一个可以用一个不能用
不能正常运行的：
<STYLE>
.spanstyle{
COLOR: #0066ff;FONT-FAMILY: 隶书;FONT-SIZE: 14pt;FONT-WEIGHT: normal;POSITION: absolute;TOP: -50px;VISIBILITY: visible
}
</STYLE>
<SCRIPT language="javascript" type="text/javascript">
var message="欢 迎 来 到 javascript 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" type="text/javascript">

document.write("<span id='span"+i+"' class='spanstyle'>");
document.write(message[i]);

}
if(document.layers){
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove=handlerMM;
</SCRIPT>
<SCRIPT language="javascript" type="text/javascript">
function pageload(){
makesnake();
window.setTimeout("pageload();",2);
}
</SCRIPT>
<html>
<body onload=javascript:pageload()>
</body>
</html>
可以正常运行的：

请高手们帮忙解决下，顺便教点js常见的错误，谢谢了
[解决办法]
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;
｝
看看你这2个大括号和别的有什么区别。。。
你是在中文下输入的吧。。改过就好了
