One string method that I found today in Python is the count function to determine how many times a given substring appears in a string. Below is the equivalent of this function in JavaScript: It is important to note that if you pass a regular expression as the target instead Read more…
One thing that I started working on last year, but unfortunately never released, was a version of jPaq which provides the ability to pick whether or not prototypal functions are created. The reason I started working on this was to somewhat satisfy the complaints of those who feel that native Read more…
One thing I needed to do recently was indent a series of strings with a variable number of tabs or spaces. Thusly, I decided to create the following function which can be used by anyone that would need such a function: The JS annotation pretty much sums up how you Read more…
A cool function that exists in Python is the range function which actually creates a list of numbers within the specified range. Once again, since I love JavaScript, here a quick imitation of this function: Of course, this is probably not a complete imitation, but as you can see it Read more…
Yesterday I wrote this post about a way to loosely imitate having array comprehensions in JavaScript. After thinking about it a bit more, I thought it would be best to change the function to be more like this: I wanted to remove the declaration of a variable which will be Read more…
In my job I have recently switched over to primarily coding in Python and I am loving the change. One thing that I find interesting is list comprehensions. Still, since my first love is JavaScript, I wanted to be able to do something similar in JavaScript and had remembered coming Read more…
Recently I have wanted to be able to inject JavaScript into pages that I visit for work purposes. At first I was using a bookmarks with JavaScript URLs to execute the code every time. Still, I wanted to have a way to inject the JavaScript code automatically on specific sites. Read more…
In this post I proved that the String.prototype.split function can behave differently in IE8 and below than it does in other browsers. For that reason, I wrote the following code that will fix the issue so that split should work the same in all browsers: It is important to note Read more…
At times I use the String#split function in order to create an array from a string based on a RegExp delimiter. Unfortunately, today I realized that some browsers act differently than others. Let’s consider the following example: In most browsers, the value of the above variable would be true which Read more…
At times you may need to add a dynamically created stylesheet to a page via JavaScript. You can do just that with the following function: It is important to note that the above function simply create the STYLE tag with the specified stylesheet content. It does not add it to Read more…
