How to adjust table headers in Angular-Datatables

This highlights how to programmatically adjust table headers after rendering angular-datatables. Note that sometimes before adjusting the headers so that they will aligned with the table body (

), a delay (via setTimeout()) is needed as the adjustment may be interrupted or prevented by any of the tables’ parent elements.

Using Composer from Java Developer’s Perspective

Background Composer is a dependency manager for PHP. It makes your life easy. If you are a Java developer and have used Apache Maven, you’ll find Composer a familiar tool. Unlike Maven, dependencies are declared in a file called composer.json

How to create classes in JavaScript

Background [wp_ad_camp_1] I must admit I used to dislike JavaScript and UI development. First, I related JavaScript to Web UI design at which I am very not good at. I do not have an artistic side when it comes to

JavaScript Object Creation and Object Methods and Properties

[wp_ad_camp_1] If you’ve read this, it merely declares JavaScript can do OOP. It did not talked about other (more advanced) OOP stuff like access modifiers, encapsulation – behaviors and properties, and inheritance. On this article, we’ll talk more on object

JavaScript scope in functions vs Java scope in methods

For years, JavaScript to me was a mere validation tool or script for web applications. I hated it. I avoided using it. This time JavaScript gets the same respect from me as Java does. If you plan to “own” (or master if you can) JavaScript and you are coming from blocked-scoped languages like Java, C#, C and C++, this is one of key things you need to keep in mind…

Working with Reference Types in JavaScript

JavaScript has both primitive and reference types. It has three primitive types: string, numeric, and boolean. Internally, these are small and fixed-sized collection of bytes that are easily and predictably manipulated at the low (primitive) levels of the JavaScript interpreter. Example of strings are ‘This is a string’ and “This is another string”. Numeric values – 1, and 3.1416. Boolean values – true or false. On the other hand, reference types are different. They include objects (including JS built-in objects), Arrays, and functions. Essentially, they can have any number of properties or elements with various types (both primitives and references), so they cannot be manipulated as easily as fixed-size primitive v

JavaScript Arrays with Elements of Different Data Types

Array with different types of data? Weird stuff! Generally, an array is collection of similar items. In Computer Science 101, this means the items are of the same data type. We have an array of integers, boolean values or strings. But in JavaScript, arrays can have elements of different types.

Type Checking in JavaScript

Okay, JavaScript is a loosely-typed language, which means you do not declare the data type of a variable explicitly. In a basic variable assignment expression, e.g., var i = 4;, the value that assigns to the variable determines the data type of the variable. As you assign different types of data to the same variable, its data type changes as well. Given the nature of JavaScript, finding out what data type a variable represents before using it is very important.
