CSS ::file-selector-button / / No Comments We all love beautifully styled form controls but, due to the differences between operating system displays, styling them can be painful. Due to that pain, we’ve created scores of libraries to mock these controls. Unfortunately that sometimes comes at the cost of accessibility, performance, etc. One control that has traditionally been tough to style is the input[type=file] element. Said input variation visually contains a button and text, all being clickable. Bit of a Frankenstein’s monster if you ask me. Can we style the button part though? We can! To style the button button portion of input[type=file], you can use ::file-selector-button: input[type=file]::file-selector-button... more → Posted in: JavaScript Tagged with: fileselectorbutton
Detect XR Support with JavaScript / / No Comments A few years ago I wrote an article about how to detect VR support with JavaScript. Since that time, a whole lot has changed. “Augmented reality” became a thing and terminology has moved to “XR”, instead of VR or AR. As such, the API has needed to evolve. The presence of navigator.xr signals that the browser supports the WebXR API and XR devices: const supportsXR = 'xr' in window.navigator; I really like using in for feature checking rather than if(navigator.xr), as simply invoking that could cause some initialization to take place. In future posts we’ll explore identifying and connecting to different devices.

How to Open a Tor Brave Window from Command Line / / No Comments I love the Brave web browser for many reasons: ad blocking, Brave rewards, crypto integration, and even a Tor tab feature. I’ll often use the Tor feature but wanted to know how I could automated opening Tor windows from command line. To open a Brave Tor tab, you can use the following command: open -a "Brave Browser" --args --incognito --tor Any time I want to remotely open a Tor tab, I can do so via a shell script. Commands are such an underused but valuable utility for apps! The post How to Open a Tor Brave Window from Command Line appeared first on David Walsh Blog.

Another Update to my Slideshow Web Component – JavaScript Support / / No Comments Last month I shared a simple web component I built to embed slideshows onto web pages. If you didn’t get a chance to read that, you can see it in action in this CodePen below: See the Pen Slideshow Web Component by Raymond Camden (@cfjedimaster) on CodePen. After I wrote this, Šime Vidas shared an excellent update to my component with some great modifications. I talked about this version in a blog post, and it’s the version I’ll be using for my post today. What am I covering today? When I demonstrated how to use my web component, it was done via a script include (well, it’s on CodePen, but you get the idea), and then a bit of HTML. Here’s an example. (And... more → Posted in: JavaScript Tagged with: Another, Component, JavaScript, Slideshow, Support, update
How to Create a Diff of Two Images / / No Comments When I was a child, I loved looking for Waldo in the “Where’s Waldo?” book series. These days I’m a sucker for TMZ’s “What’s the Big Frigin Difference” images, where TMZ slightly changes an image and you have to spot the differences between the two. That got me to thinking — how easily could I automate diff’ing two images? This StackOverflow post was gold. To create a diff of two similar images, we’ll use ImageMagick’s convert command line utility with a large host of configurations: convert '(' image1.png -flatten -grayscale Rec709Luminance ')' '(' image2.png -flatten -grayscale Rec709Luminance ')' ... more → Posted in: JavaScript Tagged with: create, Diff, images
How to Open an App from Anywhere on Mac Command Line / / No Comments Many engineers like myself live in the command line, and perform actions from command line that most others would click an icon for. I’ve always found opening apps from command line on Macs painful. You need to references the Applications directory, add .app to the name, etc. I just want to open apps by name. To open an app from any directory by its simple name, you can use the -a argument to open: open -a Cyberduck # Works regardless of case as well open -a CyBeRdUcK I love -a for a command like open. Being able to open any app by name is exactly what I want! The post How to Open an App from Anywhere on Mac Command Line appeared first on David Walsh Blog.

Customizing HTML Form Validation / / No Comments Form validation has always been my least favorite part of web development. You need to duplicate validation on both client and server sides, handle loads of events, and worry about form element styling. To aid form validation, the HTML spec added some new form attributes like required and pattern to act as very basic validation. Did you know, however, that you can control native form validation using JavaScript? validity Each form element (input, for example) provides a validity property which represents a ValidityState. ValidityState looks something like this: // input.validity { badInput: false, customError: true, patternMismatch: false, rangeOverflow: false, rangeUnderflow: false,... more → Posted in: JavaScript Tagged with: Customizing, form, HTML, Validation
