Scrolla en DIV.


Conaj

Recommended Posts

Hej!

 

Jag har försökt hitta något GRATIS script eller en tutorial på hur man ska gå till väga för att scrolla en div.

 

Jag laddar in text (PHP) i en div på en sida. Jag skulle nu vilja ha 2 knappar (länkar) som jag kan scrolla innehållet upp och ner.

 

Jag har fösökt med DynAPI. Men då dokumentationen är i det närmaste obefintlig så har jag ingen lust att implementera kod som jag inte vet vad den gör.

 

Kan något tala om hur man gör (exempelscript) eller någon bra tutorial.

 

Tack på förhand.

Behövs inte krånglas till...

<style type="text/css">
<!--
#myDiv {
  width:100px;
  height:50px;
  border:1px solid #000000;
  overflow: auto;
  }
-->
</style>

Vill inte ha scrollbars...de är så fula i andra webbläsare...därför vill jag använda mig av Javascript.

 

Fler förslag?

You set the width and height of the divs inside the style tag, you only have to

change the divScrollTextCont, Remember to set the clip the same as the width and height.

You can remove the divUp and divDown layers if you want.

This script should also work if you make the divScrollTextCont position:relative.

Then you should be able to place this inside a table or something. Just remember

that Netscape crash very easily with relative positioned divs and tables.

 

Updated with a fix for error if moving over layer before pageload.

/***************

Multiple Scripts

If you have two or more scripts that use the onload event, probably only one will run (the last one).

Here is a solution for starting multiple scripts onload:

1. Delete or comment out all the onload assignments, onload=initScroll and things like that.

2. Put the onload assignments in the body tag like in this example, note that they must have braces ().

Example: <body onload="initScroll(); initTooltips(); initMenu();">
