左右滚动字幕的代码

登陆--控制面板--首页内容维护--自定义公告栏--点击进入编辑界面,新增一个项目如"公告",把光标移到编辑框,输入:

滚动字幕：(上下)

DIV

align=center

DIV

style="OVERFLOW:

auto;

WIDTH:

159px;

HEIGHT:

145px"

MARQUEE

class=p131

scrollAmount=1

scrollDelay=60

direction=up

height=145

onmouseover="this.stop()"

onmouseout="this.start

()"

align="left"

WIDTH:

200px;

P

align=leftFONT

size=3

文字/FONT/P/MARQUEE

(左右)

marquee

direction="left"

scrollamount="1"

scrolldelay="10"

border="0"

width=500

然后点"显示源代码"保存

进入"定制我的首页"里"添加模块"在各个添加的"公告"前打"√"，保存设置即可

关于动态左右滚动字代码

主题名称：图像特殊效果br

br

特效名称：左右移动的图片br

br [修改图片名称即可][共2步]

br1、将以下代码加入到HEML的head/head之间：

script LANGUAGE="JavaScript"!--

step = 0;

obj = new Image();

function anim(xp,xk,smer) //smer = direction

{

obj.style.left = x;

x += step*smer;

if (x=(xk+xp)/2) {

if (smer == 1) step--;

else step++;

}

else {

if (smer == 1) step++;

else step--;

}

if (x = xk) {

x = xk;

smer = -1;

}

if (x = xp) {

x = xp;

smer = 1;

}

// if (smer 2) smer = 3;

setTimeout('anim('+xp+','+xk+','+smer+')', 50);

}

function moveLR(objID,movingarea_width,c)

{

if (navigator.appName=="Netscape") window_width = window.innerWidth;

else window_width = document.body.offsetWidth;

obj = document.images[objID];

image_width = obj.width;

x1 = obj.style.left;

x = Number(x1.substring(0,x1.length-2)); // 30px - 30

if (c == 0) {

if (movingarea_width == 0) {

right_margin = window_width - image_width;

anim(x,right_margin,1);

}

else {

right_margin = x + movingarea_width - image_width;

if (movingarea_width x + image_width) window.alert("No space for moving!");

else anim(x,right_margin,1);

}

}

else {

if (movingarea_width == 0) right_margin = window_width - image_width;

else {

x = Math.round((window_width-movingarea_width)/2);

right_margin = Math.round((window_width+movingarea_width)/2)-image_width;

}

anim(x,right_margin,1);

}

}

//--/script

br2、将以下代码加入到HEML的body/body之间：

img src="1548.jpg" name="picture"

style="position: absolute; top: 70px; left: 30px;" BORDER="0" WIDTH="140" HEIGHT="40"

script LANGUAGE="JavaScript"!--

setTimeout("moveLR('picture',300,1)",10);

//--/script

看这个对你有不有帮助!
