imacros查找滚动条的滚动量 [英] imacros find how much a scrollbar is scrolled

问题描述

情况:尽管我遇到了很多困难，但我还是试图制作一种可衡量滚动条在特定页面上滚动了多少的微距摄影机:

SITUATION: I am trying to make an imacro that will measure how much a scrollbar is scrolled on a specific page, though I have had various difficulties:

以下javascript代码通常用于此目的:

The following javascript code is often used for this purpose:

var vertical = document.getElementById("myDIV").scrollTop;
alert("amount scrolled vertically: " + vertical);

ATTEMPT#1:

但是，当我尝试在 js 文件的 firefox imacros扩展中使用该代码时，出现以下错误:

However, when I tried using that code in the firefox imacros extension in a js file, I get the following error:

ReferenceError:未定义文档，第1行(错误代码:-991)

产生错误的代码:

var info = document.getElementById("myDIV").scrollTop;
alert("info");

ATTEMPT#2:

所以我接下来尝试的是以下代码:

So what I tried next was the following code:

var info = window.content.document.getElementById("myDIV").scrollTop;
alert("info");

但是会出现以下错误:

错误:多进程Firefox，第208行中不支持访问内容窗口(错误代码:-991)

问题:，我是否可以测量 firefox imacros扩展程序中滚动的数量?如果是这样，怎么办?可悲的是，过去几天我一直坚持这一点.

QUESTION: Is there a way for me to measure the amount scrolled in the firefox imacros extension? And if so, how? I have sadly been stuck on this for the past few days.
