下面框中为脚本显示区
脚本说明： 把如下代码加入<body>区域中: <SCRIPT LANGUAGE="JavaScript"> <!-- Begin msg ="I love javascript very much!"; align="center"; speed=250; up=true; spas=" "; for (a=0;a<=12;a++) {spas+=" "} msg=spas+msg+spas; j=eval(-1); stop=msg.length; document.write("<form name='form'><table border=0 cellspacing=0 " +"cellpadding=0 align="+align+">"); for (i=1;i<=13;i++) { document.write("<tr><td><input type=text name=\"box"+i+"\" size=1>"); document.write("</td></tr>"); } document.write("</table></form>"); function scrollIt() { j++; with (document.form) { if ((j+12) <= stop) { box1.value = msg.charAt(j); box2.value = msg.charAt(j+1); box3.value = msg.charAt(j+2); box4.value = msg.charAt(j+3); box5.value = msg.charAt(j+4); box6.value = msg.charAt(j+5); box7.value = msg.charAt(j+6); box8.value = msg.charAt(j+7); box9.value = msg.charAt(j+8); box10.value = msg.charAt(j+9); box11.value = msg.charAt(j+10); box12.value = msg.charAt(j+11); box13.value = msg.charAt(j+12); } else { j=0; } } setTimeout("scrollIt()",speed); } scrollIt(); // End --> </SCRIPT>
