滚动到锚点
我有以下 userjs,旨在删除 URL 的锚点部分,但仍然跳转到它:
// ==UserScript==
// @name PurgeAnchor
// @include *
// ==/UserScript==
(function() {
var reg=/^(.*)\#(.*)$/;
var match=reg.exec(location);
function ObjectPosition(obj) {
var curtop = 0;
if(obj.offsetParent)
while(1)
{
curtop += obj.offsetTop;
if(!obj.offsetParent)
break;
obj = obj.offsetParent;
}
else if(obj.y)
curtop += obj.y;
return curtop;
}
if(match) {
document.location.replace(match[1]);
sessionStorage.setItem("anchor", match[2]);
}
window.addEventListener("load", (function() {
var anchor=sessionStorage.getItem("anchor");
if(anchor!==null) {
var obj=document.anchors.item(anchor);
// var obj=document.getElementById(anchor);
// if(obj===null) {
// obj=document.getElementsByName(anchor)[0];
// }
var pos=0;
if(obj!==null) {
pos=ObjectPosition(obj);
window.scrollTo(0, pos);
}
sessionStorage.removeItem("anchor");
}
}), false);
})()
问题是,如果我有一个带有名称集的空 标记,它无法跳。
obj.scrollIntoView()
也失败。 Opera-10.52_pre6306,Gentoo。
I have the following userjs which is intended to remove anchor part of the URL but still jump to it:
// ==UserScript==
// @name PurgeAnchor
// @include *
// ==/UserScript==
(function() {
var reg=/^(.*)\#(.*)$/;
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.anchors.item(anchor);
// 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.

好吧,花了一段时间,但我想我终于明白了:
Ok, it took a while, but I think I finally got it:
