要完成此效果需要两个步骤 第一步：把如下代码加入到<head>区域中 <SCRIPT LANGUAGE="JavaScript"> <!-- Begin function mklist(n) { this.length=n; for (var c=1 ; c <= n ; c++) { this[c]=0; } return this; } function browserdelay() { var retval=500; if (navigator.userAgent.indexOf("Win") != 0) { retval=150; } else if (navigator.userAgent.indexOf("Mac") != 0) { retval=500; } else if (navigator.userAgent.indexOf("X11") != 0) { retval=750; } return retval; } function mkcfg(n) { this.num=1; this.seed=0; this.list=new mklist(n); this.type=new mklist(n); this.delay=browserdelay(); this.timer=0; this.showurl=(5 * 1000); this.looping=true; this.msgdisp=(4 * 1000); this.barwidth=100; return this; } function urlfix(obj) { window.clearTimeout(window.config.timer); window.defaultStatus=obj.href; window.config.timer=window.setTimeout("sbprint()",window.config.showurl); return true; } function scrollit_r2l() { var out=" "; var c=0; if (window.config.seed <= window.config.barwidth && window.config.seed > 0) { for (c=0 ; c < window.config.seed ; c++) { out+=" "; } out+=window.config.list[window.config.num]; window.config.seed--; window.status=out; window.config.timer=window.setTimeout("scrollit_r2l()",window.config.delay); } else if (window.config.seed <= 0) { if (-window.config.seed < window.config.list[window.config.num].length) { out+=window.config.list[window.config.num].substring(-window.config.seed,window.config.list[window.config.num].length); window.config.seed--; window.status=out; window.config.timer=window.setTimeout("scrollit_r2l()",window.config.delay); } else { window.status=" "; window.config.num++; window.config.timer=window.setTimeout("sbprint()",window.config.msgdisp); } } } window.config=new mkcfg(7); window.config.list[1]="这里改写你的第一条信息"; window.config.type[1]=0; window.config.list[2]="这里改写你的第二条信息"; window.config.type[2]=0; window.config.list[3]="这里改写你的第三条信息"; window.config.type[3]=0; window.config.list[4]="这里改写你的第四条信息"; window.config.type[4]=0; window.config.list[5]="这里改写你的第五条信息"; window.config.type[5]=0; window.config.list[6]="这里改写你的第六条信息"; window.config.type[6]=0; window.config.list[7]="这里改写你的第七条信息"; window.config.type[7]=0; function sbprint() { if (window.config.num <= window.config.list.length) { if (window.config.type[window.config.num] == 0) { window.status=window.config.list[window.config.num]; window.config.num++; window.clearTimeout(window.config.timer); window.config.timer=window.setTimeout('sbprint()',window.config.msgdisp); } else if (window.config.type[window.config.num] == 1) { window.config.seed=window.config.barwidth; scrollit_r2l(); } } else if (window.config.looping) { window.config.num=1; window.clearTimeout(window.config.timer); window.config.timer=window.setTimeout('sbprint()',window.config.delay); } } // End --> </script> 第二步：把“onload="window.config.timer=window.setTimeout('sbprint()',window.config.delay);"”加在<body>区域中 例如：<body onload="window.config.timer=window.setTimeout('sbprint()',window.config.delay);">
