状态栏特效

文字在状态栏上从左往右一个一个地显示，就象你打出的字一样

代码：<script language="JavaScript">
var msg = "欢迎来到网页特效世界，请多提意见。谢谢! " ;
var interval = 120
var spacelen = 120;
var space10=" ";
var seq=0;
function Helpor_net() {
len = msg.length;
window.status = msg.substring(0, seq+1);
seq++;
if ( seq >= len ) {
seq = 0;
window.status = '';
window.setTimeout("Helpor_net();", interval );
}
else
window.setTimeout("Helpor_net();", interval );
}
Helpor_net();
</script>
