适用版本：
DZ 5.0
开发此插件体会：
继本人开发的 D4版本此插件得到了不少朋友的支持！
http://www.discuz.net/viewthread.php?tid=301123
从DZ 版本升级后本人没时间开发此插件！而此插件开发也很简单！可没人做！
有很多朋友来消息询问我D5版本的怎么还不出来
故本人在此通宵开发此插件！
需要修改部分：
include/common.js
index.php
templates/default/discuz.htm
开始操作：
打开include/common.js
在最后插入:
var marqueeInterval=new Array();
var marqueeId=0;
var marqueeDelay=3000;
var marqueeHeight=15;
function initMarquee() {
var str=marqueeContent[0];
document.write('<div id=marqueeBox style="overflow:hidden;height:'+marqueeHeight+'px" onmouseover="clearInterval(marqueeInterval[0])" onmouseout="marqueeInterval[0]=setInterval(\'startMarquee()\',marqueeDelay)"><div>'+str+'</div></div>');
marqueeId++;
marqueeInterval[0]=setInterval("startMarquee()",marqueeDelay);
}
function startMarquee() {
var str=marqueeContent[marqueeId];
marqueeId++;
if(marqueeId>=marqueeContent.length) marqueeId=0;
if(document.getElementById('marqueeBox').childNodes.length==1) {
var nextLine=document.createElement('DIV');
nextLine.innerHTML=str;
document.getElementById('marqueeBox').appendChild(nextLine);
} else {
document.getElementById('marqueeBox').childNodes[0].innerHTML=str;
document.getElementById('marqueeBox').appendChild(document.getElementById('marqueeBox').childNodes[0]);
document.getElementById('marqueeBox').scrollTop=0;
}
clearInterval(marqueeInterval[1]);
marqueeInterval[1]=setInterval("scrollMarquee()",20);
}
function scrollMarquee() {
document.getElementById('marqueeBox').scrollTop++;
if(document.getElementById('marqueeBox').scrollTop%marqueeHeight==(marqueeHeight-1)){
clearInterval(marqueeInterval[1]);
}
}复制代码
打开 templates/default/discuz.htm
搜索
<!--{if !empty($announcements)}-->复制代码
将
<div id="announcement" style="clear: both; width: {TABLEWIDTH}">$announcements</div>
<script type="text/javascript">announcement();</script>复制代码
替换为
<div id="announcement" style="clear: both; width: {TABLEWIDTH}"><script language="javascript">
var marqueeContent=new Array();
$announcements
initMarquee();
</script></div>复制代码
打开index.php
将：
if(empty($gid)) {
$announcements = $space = '';
if($_DCACHE['announcements']) {
foreach($_DCACHE['announcements'] as $announcement) {
if(empty($announcement['redirect'])) {
$announcements .= $space.'<a href="announcement.php?id='.$announcement['id'].'#'.$announcement['id'].'"><span class="bold">'.$announcement['subject'].'</span> '.
'('.gmdate($dateformat, $announcement['starttime'] + $timeoffset * 3600).')</a>';
} else {
$announcements .= $space.'<a href="'.$announcement['message'].'" target="_blank"><span class="bold">'.$announcement['subject'].'</span> '.
'('.gmdate($dateformat, $announcement['starttime'] + $timeoffset * 3600).')</a>';
}
$space = ' ';
}
}复制代码
替换为
if(empty($gid)) {
$announcements = $space = '';
$announcementn = 0;
if($_DCACHE['announcements']) {
foreach($_DCACHE['announcements'] as $announcement) {
if(empty($announcement['redirect'])) {
$announcements .= 'marqueeContent['.$announcementn.']=\'<a href="announcement.php?id='.$announcement['id'].'#'.$announcement['id'].'"><span class="bold">'.$announcement['subject'].'</span>('.gmdate($dateformat, $announcement['starttime'] + $timeoffset * 3600).')</a>\';';
} else {
$announcements .= 'marqueeContent['.$announcementn.']=\'<a href="'.$announcement['message'].'" target="_blank"><span class="bold">'.$announcement['subject'].'</span>('.gmdate($dateformat, $announcement['starttime'] + $timeoffset * 3600).')</a>\';';
}
$announcementn++;
}
