可以文本显示的公告栏
一个可以文本显示的公告栏，可以在多处使用，绝对不可错过！
脚本说明:
第一步：把如下代码加入<head>区域中
<script language="JavaScript">
<!--Activate Cloaking Device
var i = 0;
// used to cycle thru messages
var TextNumber = -1;
// array of messages
var TextInput = new Object();
// used to load manipulate message
var HelpText = "";
// used to load message
var Text = "";
// length of timeout (smaller is faster)
var Speed = 50;
// used to display message number
var message = 0;
// used to position text in ver 2.0
var addPadding = "rn";
// Each element of TextInput represents a single message.
TextInput[0] = "今天注意了有新的任务布置";
TextInput[1] = "欢迎你的光临！本站为你提供大量javascript下载";
TextInput[2] = "重点介绍Javascript";
TextInput[3] = "与制作网页特效密切相关的技术";
TextInput[4] = "本站同时有影音空间等栏目";
TextInput[5] = "还有新闻及健康方面的资料";
TextInput[6] = "还有宽带网方面的大量技术文章";
TextInput[7] = "本站网址：http://www.phprm.com";
TotalTextInput = 7; // (0, 1, 2, 3, 4, 5, 6, 7)
// Positioning and speed vary between versions.
var Version = navigator.appVersion;
if (Version.substring(0, 1) == 3) {
Speed = 200;
addPadding = "";
}
for (var addPause = 0; addPause <= TotalTextInput; addPause++) {
TextInput[addPause] = addPadding + TextInput[addPause];
}
var TimerId
var TimerSet = false;
// Called by >>> button (display next message) .
function nextMessage() {
if (!TimerSet) {
TimerSet = true;
clearTimeout(TimerId);
if (TextNumber >= TotalTextInput) {
alert("This is the end of the list!");
TimerSet = false;
} else {
TextNumber += 1;
message = TextNumber + 1;
document.forms[0].elements[2].value = message;
Text = TextInput[TextNumber];
HelpText = Text;
}
teletype();
}
}
// Gets and displays character from rollMessage() .
// Variable Speed controls length of timeout and thus the speed of typing.
function teletype() {
if (TimerSet) {
Text = rollMessage();
TimerId = setTimeout("teletype()", Speed);
document.forms[0].elements[0].value = Text;
}
}
// Pulls one character at a time from string and returns (as Text) to function teletype() for displaying.
function rollMessage() {
i++;
var CheckSpace = HelpText.substring(i - 1, i);
CheckSpace = "" + CheckSpace;
if (CheckSpace == " ") {
i++;
}
if (i >= HelpText.length + 1) {
TimerSet = false;
Text = HelpText.substring(0, i);
i = 0;
return (Text);
}
Text = HelpText.substring(0, i);
return (Text);
}
// Initially called by onLoad in BODY tag to load title.
function initTeleType() {
Text = "rn Manual Tele-Type Display";
document.forms[0].elements[0].value = Text;
}
// Called by <<< button (get previous message).
function lastMessage() {
if (!TimerSet && TextNumber != -1) {
TimerSet = true;
clearTimeout(TimerId);
if (TextNumber <= 0) {
alert("This is the beginning of the list!");
TimerSet = false;
} else {
TextNumber -= 1;
message = TextNumber + 1;
document.forms[0].elements[2].value = message;
Text = TextInput[TextNumber];
HelpText = Text;
}
teletype();
}
}
// Deactivate Cloaking --></script>
第二步：在<body>区域中加入如下代码:
<form> <table CELLSPACING="0" CELLPADDING="0" WIDTH="17%"> <tr> <td width="100%" colspan="3" valign="top"><div align="center"><p><textarea NAME="teletype" ROWS="3" COLS="28" wrap="yes"></textarea> </td> </tr> <tr align="center"> <td width="40%" valign="top" bgcolor="#0000A0"><input TYPE="button" VALUE="公告栏" onClick="lastMessage()"></td> <td width="30%" bgcolor="#0000A0" valign="top"><input TYPE="text" value="共8条" SIZE="5" name="1"></td> <td width="30%" bgcolor="#0000A0" valign="top"><input TYPE="button" VALUE="阅 读" onClick="nextMessage()"></td> </tr> </table> </form>
