does anybody know a command to bind "scroll to top"/ "jump to top" function to a button?
I found something more fancy, but would like to have a more simple version: https://chrome.google.com/extensions/detail/chiikmhgllekggjhdfjhajkfdkcngplp
Much appreciated.
Well, you can just do the following, scroll to X=0, and Y=0, and thats it https://developer.mozilla.org/en/window.scroll
window.scroll(0, 0);
If you want to hook that up to Google Chrome Extensions, all you need to do is create a JavaScript file and inject it to your page:
background.html
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.executeScript(tab.id, {code: 'window.scroll(0, 0);'});
});
manifest.json
Make sure you have the tabs permission and browser action:
...
...
"browser_action": {
"default_icon": "some_icon.png",
},
"permissions": [
"tabs",
"http://*/*"
],
...
...
I havn't tested that, but it will give you an idea how to send a command from Chrome to Website through extensions via browser action button. Once you click on that button, it will execute a script to scroll that page to the top.absolute top.

(Simple, no over-thinking.)
To create an element with id "top" at the beginning of body, and assign the href of the "go to top" button to "#top", or add an event listener to it.
If you want it to show on the page persistently, use CSS rule position: fixed and appropriate other attributes.
Chrome extensions are html/js, right ? So just set the scrollTop attribute of <body> to 0. Maybe there'is a more elegant way but this work :
<script>
function setScroll()
{
document.getElementsByTagName("body")[0].scrollTop = 0;
}
</script>
<input type="button" value="Set scrollTop to 50" onclick="setScroll();" />
