Automated clicking on HTML elements – Chee Wee’s blog

Posted by jpluimers on 2019/12/03

Magic from the JavaScript console: [WayBack] Automated clicking on HTML elements – Chee Wee’s blog: IT solutions for Singapore and companies worldwide.

This is the code he uses because [WayBack] getElementsByClassName returns an array ([WayBack] getElementById returns one reference or null, but many sites still develop without assigning an ID to their elements):

function clickRefresh() {
  ImStillHere = document.getElementsByClassName("Button Success");
  if (ImStillHere.length > 0)
    ImStillHere[0].click();
  document.getElementsByClassName("refresh-widget")[0].click();
}
setInterval(clickRefresh, 1000);

I like the approach. Now I need to find a way to automate this in some kind of plug-in.

Dixin’s Blog – Use Fiddler with Node.js

Posted by jpluimers on 2019/10/30

[Archive.is] Dixin’s Blog – Use Fiddler with Node.js Fiddler is an useful HTTP proxy debugger on Windows. It would be nice if it can work with Node.js applications. To do this, just need to proxy Node.js requests through Fiddler… on port 8888.

There is a snippet for it at github/Dixin/CodeSnippets/…/fiddler.js (now moved to [WayBack] github.com/Dixin/Blog/…/Blog/Dixin.Nodejs/fiddler.js)

It complements a few posts I’ve written about Fiddler using port 8888 as a proxy before:

GitHub – slikts/js-equality-game: The Worst Minesweeper 💣 Ever

Posted by jpluimers on 2019/09/10

[WayBack] GitHub – slikts/js-equality-game: The Worst Minesweeper 💣 Ever:

It’s in response to claims like this one by the well-known author getify:

However, implicit coercion is a mechanism that can be learned, and moreover should be learned by anyone wishing to take JavaScript programming seriously. Not only is it not confusing once you learn the rules, it can actually make your programs better! The effort is well worth it.

You can play it on [WayBack] JavaScript Equality Table Game: Find out how well you know (or don’t know) the JavaScript == operator rules

It reminds me of the hilarious video on Wat – Destroy All Software Lightning Talk : Gary Bernhardt : Free Download, Borrow, and Streaming : Internet Archive

Every time I try, I’m reminded of: You Don’ t Know JavaScript

Posted by jpluimers on 2019/09/05

I forgot how I originally bumped into the book series, but every time I try to program in JavaScript I’m reminded of them: You Don’ t Know JavaScript.

Originally a KickStarter project, they are now on GitHub and there is a Twitter account irregularly posting about them:

… compare two JSON structures and pin-point … the differences – – Nicholas Ring – Google+

Posted by jpluimers on 2019/08/20

I’ve added a few WayBack/Archive.is links to the interesting comments by Zoë Peterson from Scooter Software (of Beyond Compare fame) at [WayBack] … compare two JSON structures and pin-point … the differences – – Nicholas Ring – Google+:

Beyond Compare 4 has an optional “JSON sorted” file format that uses jq to pretty print and sort JSON data before comparing it. It’s not included out of the box yet, but you can get a copy here:

If you’re interested in an actual algorithm and not just an app, I don’t have a suggestion handy, but could dig one up. Tree alignment is more complicated than sequence alignment and we did do research into it, but it was quite a few years ago and didn’t get incorporated into BC. XML alignment algorithms were being actively researched back in the aughts and they should trivially transfer to JSON.
…

It looks like our research mostly ended around 2002, and I wasn’t personally involved in it, so I don’t know how helpful this will be, but here’s what I have:

The general idea in the thread is that JSON – though not as formalised as XML – does have structure, so if you can normalise it, then XML ways of differencing should work.

Normalisation also means that you need to normalise any floating point, date time, escaping, quoting, etc. Maybe not for the faint of heart.

Web Audio Modem

Posted by jpluimers on 2019/07/04

Geekpr0n: [WayBack] Web Audio Modem

What do you do when you cannot copy text between computers due to lack of internet connectivity? I built a modem using the Web Audio API, allowing data transfer via audio.

It is on github at martme/webaudio-modem: Encode and decode text using the Web Audio API to enable offline data transfer between devices.

There are three demo pages at [WayBack] martinmelhus.com – Web Audio Encoder too:
