News Ticker - Java Script

Question

Hello,
This is the java script I use to create a news ticker on one of my pages. It can be included anywhere in your application - region header, body or footer:
<script language="JavaScript1.2">
Cross browser Marquee script- © Dynamic Drive (www.dynamicdrive.com)

//Specify the marquee's width (in pixels)
var marqueewidth="300px"
//Specify the marquee's height
var marqueeheight="20px"
//Specify the marquee's marquee speed (larger is faster 1-10)
var marqueespeed=1
//configure background color:
var marqueebgcolor="#DEFDD9"
//Pause marquee onMousever (0=no. 1=yes)?
var pauseit=1
//Specify the marquee's content (don't delete <nobr> tag)
//Keep all content on ONE line, and backslash any single quotations (ie: that\'s great):
var marqueecontent='<nobr><font face="Arial"><b>This is where my text goes.<b/></font></nobr>'
marqueespeed=(document.all)? marqueespeed : Math.max(1, marqueespeed-1) //slow speed down by 1 for NS
var copyspeed=marqueespeed
var pausespeed=(pauseit==0)? copyspeed: 0
var iedom=document.all||document.getElementById
if (iedom)
document.write('<span id="temp" style="visibility:hidden;position:absolute;top:-100px;left:-9000px">'+marqueecontent+'</span>')
var actualwidth=''
var cross_marquee, ns_marquee
function populate(){
if (iedom){
cross_marquee=document.getElementById? document.getElementById("iemarquee") : document.all.iemarquee
cross_marquee.style.left=parseInt(marqueewidth)+8+"px"
cross_marquee.innerHTML=marqueecontent
actualwidth=document.all? temp.offsetWidth : document.getElementById("temp").offsetWidth
else if (document.layers){
ns_marquee=document.ns_marquee.document.ns_marquee2
ns_marquee.left=parseInt(marqueewidth)+8
ns_marquee.document.write(marqueecontent)
ns_marquee.document.close()
actualwidth=ns_marquee.document.width
lefttime=setInterval("scrollmarquee()",20)
window.onload=populate
function scrollmarquee(){
if (iedom){
if (parseInt(cross_marquee.style.left)>(actualwidth*(-1)+8))
cross_marquee.style.left=parseInt(cross_marquee.style.left)-copyspeed+"px"
else
cross_marquee.style.left=parseInt(marqueewidth)+8+"px"
else if (document.layers){
if (ns_marquee.left>(actualwidth*(-1)+8))
ns_marquee.left-=copyspeed
else
ns_marquee.left=parseInt(marqueewidth)+8
if (iedom||document.layers){
with (document){
document.write('<table border="0" cellspacing="0" cellpadding="0"><td>')
if (iedom){
write('<div style="position:relative;width:'+marqueewidth+';height:'+marqueeheight+';overflow:hidden">')
write('<div style="position:absolute;width:'+marqueewidth+';height:'+marqueeheight+';background-color:'+marqueebgcolor+'" onMouseover="copyspeed=pausespeed" onMouseout="copyspeed=marqueespeed">')
write('<div id="iemarquee" style="position:absolute;left:0px;top:0px"></div>')
write('</div></div>')
else if (document.layers){
write('<ilayer width='+marqueewidth+' height='+marqueeheight+' name="ns_marquee" bgColor='+marqueebgcolor+'>')
write('<layer name="ns_marquee2" left=0 top=0 onMouseover="copyspeed=pausespeed" onMouseout="copyspeed=marqueespeed"></layer>')
write('</ilayer>')
document.write('</td></table>')
</script>
This works fine and I would like to include some dynamic content into this script. Either some page iteme content or even some query results. My java script knowledge is quite "skinny" so I got to ask how to do that?
Thanks in advance,
Denes

Answer 1

Denes,
I just came across your thread.
Just replace within
var marqueecontent='<nobr><font face="Arial"><b>This is where my text goes.<b/></font></nobr>'...
the: "THIS is where the text goes." with: &P1_text.
and you can manipulate the text dynamically.
Ofcourse you hv to create the item P1_text and shortly after you keyed in s.th. and push "Enter" - then the data is in the Session (look at Session in Developer bar).
After "Enter" the ticker/marquee works with your data.
Alternative 2:
Define in Application Attributes under Static Substitution Strings a "GLOBAL_ITEM" with a value: say: my News - then replace &P1_TEXT. by &GLOBAL_ITEM. (beware of the '.' after the item !!! it has to be there !!
Alternative 3:
Work with a table:
A)Define a table called "NEWS" with the fields News_id, text, active_inactive - work with sequence..
B) Define form and report for data entry. In the form go to the item "active_inactive" and modify iot to be a radio-button with LOV : STATIC: Yes,No
C) still use the item P1_text and in the attributes of the item go to "Source" - select "SQL-Query" and key in:
select text from news where active_inactive = 'Yes' - modify the P1_text item as "hidden"
--> now you can manage your news and just the "Active" news are shown.
Advanced: make sure, that only one record is active !!
Have fun !! (:-)
