I have the following userjs which is intended to remove
anchor part of the URL but still jump to it:
// ==UserScript==
// @name PurgeAnchor
// @include *
// ==/UserScript==
(function() {
var reg=/^(.*)\#(.*)$/;
var match=reg.exec(location);
function ObjectPosition(obj) {
var curtop = 0;
if(obj.offsetParent)
while(1)
{
curtop += obj.offsetTop;
if(!obj.offsetParent)
break;
obj = obj.offsetParent;
}
else if(obj.y)
curtop += obj.y;
return curtop;
}
if(match) {
document.location.replace(match[1]);
sessionStorage.setItem("
anchor", match[2]);
}
window.addEventListener("load", (function() {
var anchor=sessionStorage.getItem("
anchor");
if(anchor!==null) {
var obj=document.getElementById(anchor);
if(obj===null) {
obj=document.getElementsByName(anchor)[0];
}
var pos=0;
if(obj!==null) {
pos=ObjectPosition(obj);
window.scrollTo(0, pos);
}
sessionStorage.removeItem("
anchor");
}
}), false);
})()
The problem is that if I have an empty <a> tag with the name set, it fails to jump. obj.scrollIntoView() also fails.
