userscript | Greasemonkey 脚本

I'm generating two files, userscript.meta.js and userscript.user.js. I need the output of userscript.meta.js to be placed at the very beginning of userscript.user.js.

Add-Content doesn't seem to accept a parameter to prepend and Get-Content | Set-Content will fail because userscript.user.js is being used by Get-Content.

I'd rather not create an intermediate file if it's physically possible to have a clean solution.

How to achieve this?

I'm looking for a browser addon, userscript or some simple way that would display the URL of a link on the mouse position instead of the bottom left corner, like this for example.

Edit: It was easier than I thought, got it working with an one line userscript.

I want to change the values of the buttons on the page with Tampermonkey, but I can't change it because it says the button is undefined?

HTML part

Trying to write a userscript for TamperMonkey to be running in browser for bypassing a waiting time as a training. Here is the script used in that page:

I am a user of this website. The reason that I want to get elements of the website is its web design is so inconvenient that I tried to write a script, not manully, to modify some elements' value. But I encountered an issue that I cannot access an element by getElementsByName("name") or getElementById("name") UNTIL I inspect the element by CTRL + SHIFT + C in developer mode. BTW, I can't get Elements even after inspecting on Firefox ESR 78.10.1.

You guys can tried to see what is the problem. This is the screenshot on Edge Chromium as I try to get the username .

As I have researched, some says the page is not fully loaded, but I wrote this js to test if it is loaded.

I have a tampermonkey script with this header:

I'm trying to find the corresponding code for puppeteer to automate a button press.

In a userscript it can be done easily via

I did this tampermonkey script to parse my gmail inbox items and add a button linking to our Redmine Issue Tracker, so I can open the thread without having to open the email. This button I added, immediately open a new tab and switch focus to it.

It works fine, except that every time I click the button, it also opens the email on the Gmail page/browser tab. To fix this, I added a setTimeout(function() { window.history.go(-1); }, 1000) to jump back after opening the link.

The problem is that this does not allow me to open several issues at once, i.e., by holding the Ctrl+Click because it opens the email and jumps back (big flickering).

How could I stop the email from opening when I click on the button I added?

I tried setting the timeout to 0, i.e., setTimeout(function() { window.history.go(-1); }, 0), but this does not helps because GMail opens the email both, in the current browser tab/page and in a new page (along with my Redmine page), then I have 2 new pages opened when I click my button with Ctrl+Click.

1. Is there something I could add to setTimeout(..., 0) which could cancel the email opening before it starts? (So I can open several tabs at once by Holding the Ctrl button)
2. Or is there a way to remove the click event from opening the email when I click on the button I just added? (So I can open several tabs at once by Holding the Ctrl button)

For the life of me I cannot get this to work.

I'm trying to write a userscript with tampermonkey that is @require'ing two jQuery resources - jQuery and jQuery UI.

Every single time, chrome's console gives me two to four errors, and they all looks like this:

core-c30de8a3f5468380db0b.js:1 GET about:blank net::ERR_UNKNOWN_URL_SCHEME

When I remove the two @requires, those errors go away. I've tried it with and without the window.jQ, http and https, pulling from jQuery directly and the Google ajax version, I've tried running at document start and document idle, I've tried about everything. All the rest of the script works, but requiring doesn't and obviously the jQuery bit doesn't.

Here is everything I have so far:
