Strongly Typed Events in TypeScript using an event list (Part 3)
In this tutorial I explore how an event list can be used to support scenarios with classes with a multitude of events. There is a way to decrease the number of private backing variables using an EventList
Using strongly typed events in TypeScript with interfaces (Part 2)
In a previous tutorial I explained how events can be implemented as properties on a class using Strongly Typed Events for TypeScript. Let’s explore how these work on interfaces. Interfaces work a little different, because they don’t have getters and setters on them (at least nog in TypeScript 1.8). Let’s explore how these work on interfaces.
Strongly typed event handlers in TypeScript (Part 1)
As a C# programming I have a lot of interest in the TypeScript project. Lately I’ve been playing around with it to look what it can do. I found myself in need of some event handling, so I decided to build something that looks like the event handling .Net gives you.
Many small applications need to store user credentials, but it’s hard to create a good username/password infrastructure. What if you could just use a small XML file with credentials that don’t actually stores the password, but just a hash and some salt.
Little life saver: parsing HTML entities
How to do a ‘select-all’ focus on a TextArea upon tab?
When tabbing through the fields I realized that the input focus behaves different from the TextArea. The TextArea doesn’t select its text… but it can be fixed by adding some jQuery.
Click to ‘select all’ on the PRE element
When you want to display code, you’re probably working with pre elements. The fact that they can contain markup make them really effective for syntax highlighting. I’ve used Knockout en comment binding to generate code into a pre field and that’s really cool.
Subscribe to all changes of an entire Knockout ViewModel
Knockout is amazing. It is fast and intuitive. I use the subscribe function a lot, but I found myself lacking a general subscribe that allows me to track the changes of an entire ViewModel, so I created one myself that even supports unsubscribe and throttling.
Solving Knockout JS calculated bindings Syntax Error
Doing calculations on Knockout data-binds might result into a “Uncaught SyntaxError: Unable to parse bindings” error. Solution: use an anonymous function!
