Scroll to Top
Looking to implement a scrolling to "top button".
Example: http://www.animeinspirations.com/
My forum: http://forums.animeinspirations.com/
Not sure what I am doing wrong, if I am implementing the code incorrectly or if the javascript is written wrong.
Board Version: phpBB3
I don't necessarily need the javascript, but its probably required to have the floating image that scrolls with the page. Additionally, if someone has a fix to implement a static scroll to top (basic click this link, sends you to top of page kind of deal) that can be attached to an image (near the footer for example) that would work as well.
I realize this is a tricky one, appreciate any support.
Works. Much appreciated.

- Code:
//** jQuery Scroll to Top Control script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** Available/ usage terms at http://www.dynamicdrive.com (March 30th, 09')
//** v1.1 (April 7th, 09'):
//** 1) Adds ability to scroll to an absolute position (from top of page) or specific element on the page instead.
//** 2) Fixes scroll animation not working in Opera.
var scrolltotop={
//startline: Integer. Number of pixels from top of doc scrollbar is scrolled before showing control
//scrollto: Keyword (Integer, or "Scroll_to_Element_ID"). How far to scroll document up when control is clicked on (0=top).
setting: {startline:100, scrollto: 0, scrollduration:1000, fadeduration:[500, 100]},
controlHTML: '<img src="http://4.bp.blogspot.com/-4EhTTBYpH7I/UQxorsZeTGI/AAAAAAAAChc/fFJupss47cA/s1600/jquery_scroll_icon.png" style="width:48px; height:48px" />', //HTML for control, which is auto wrapped in DIV w/ ID="topcontrol"
controlattrs: {offsetx:5, offsety:5}, //offset of control relative to right/ bottom of window corner
anchorkeyword: '#top', //Enter href value of HTML anchors on the page that should also act as "Scroll Up" links
state: {isvisible:false, shouldvisible:false},
scrollup:function(){
if (!this.cssfixedsupport) //if control is positioned using JavaScript
this.$control.css({opacity:0}) //hide control immediately after clicking it
var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto)

.attr({title:'Scroll Back to Top'})
.click(function(){mainobj.scrollup(); return false})

if (document.all && !window.XMLHttpRequest && mainobj.$control.text()!='') //loose check for IE6 and below, plus whether control contains any text
mainobj.$control.css({width:mainobj.$control.width()}) //IE6- seems to require an explicit width on a DIV containing text
