IFRAME scroller

**agmoss** · 04-16-2005, 03:36 AM

I am looking for some ideas on how to get the scroller to reset to the top of the external document AND have the initialdelay work. Currently the script allows for the initial delay on the first run through only.

Thanks

Warning: Please include a link to the DD script in question in your post. See this thread for the proper posting format for asking a question.

That being said, the solution here, if I understand you, is to change this:

Code:

function scrollDiv(){
dataobj.style.top=parseInt(dataobj.style.top)-scrollspeed+"px"
if (parseInt(dataobj.style.top)<thelength*(-1))
dataobj.style.top="5px"
setTimeout("scrollDiv()",40)
}

to this:

Code:

function scrollDiv(){
dataobj.style.top=parseInt(dataobj.style.top)-scrollspeed+"px"
if (parseInt(dataobj.style.top)<thelength*(-1)){
dataobj.style.top="5px"
setTimeout("scrollDiv()", initialdelay)
}
else
setTimeout("scrollDiv()",40)
}

Enjoy!

Thanks....didn't seem to work so I likely have not explained well enough. Here's the link to the external.htm file where the script is found. I am looking to have the scroll delay (based on the initialdelay variable) EACH time it is going to scroll through.

Thanks for your help.

Worked here. I'll paste in the whole file. It is set to 5 second initial delay. It will pause for 5 seconds before each run through.

HTML Code:

<!-- External.htm source-->
<html>
<body>

<div id="datacontainer" style="position:absolute;left:1px;top:10px;width:100%" onMouseover="scrollspeed=0" onMouseout="scrollspeed=cache">

Got it....thanks!

Hi! I'm not sure if this is the same problem as I am having, but what I am getting is the external file reloading once the scroller has come to the end of the file and what I would like to happen is for the file to just scroll back up again rather than just jumping back into position. Is this possible?

http://www.spoonofmilk.com/arcproduction/ is the place I am using the script

Thanks!

I think I see what you are after, the scroller jumps to the top but, you would rather it slide in from the bottom. To get that effect, you can change the top restart position (default of 5px) hard coded into the scrollDiv() function on the external page to be about the height of your iframe on the container page (looked like about 250px to me). In plain English, find this function on latest.html:

Code:

function scrollDiv(){
dataobj.style.top=parseInt(dataobj.style.top)-scrollspeed+"px"
if (parseInt(dataobj.style.top)<thelength*(-1))
dataobj.style.top="5px"
setTimeout("scrollDiv()",40)
}

Change it to this:

Code:

function scrollDiv(){
dataobj.style.top=parseInt(dataobj.style.top)-scrollspeed+"px"
if (parseInt(dataobj.style.top)<thelength*(-1))
dataobj.style.top="255px"
setTimeout("scrollDiv()",40)
}
