If you'd like a "back to top" button to appear alongside the section headers in articles, just add the following code to your user Javascript or your common Javascript: <syntaxhighlight lang="javascript"> $( function () { var elems = document.getElementsByClassName('editsection'); // *** NOTE: ClassName may need to be 'mw-editsection' instead for (i = 0; i < elems.length; i++) { var span = document.createElement('span'); var link = document.createElement('a'); link.href = '#top'; link.appendChild(document.createTextNode('back to top')); span.appendChild(document.createTextNode('[')); span.appendChild(link); span.appendChild(document.createTextNode('] ')); elems[i].insertBefore(span, elems[i].firstChild); } }); </syntaxhighlight>
This only works if the user is logged in and can edit the page.
