A week ago someone asked me how they can format a date so that it returns the MM/DD/YYYY format. The following is a definition for a function that does just that: The following code is an example of how you would use this code: The following is a JSBin page Read more…
There have been many times when I needed a way to define a function (or variable) only if it wasn’t already defined. Since this seems to be such a common situation, I decided to write a function which will only define a variable, in a given namespace if a definition Read more…
One thing that most JavaScript writers do now, which is a good practice, is they create namespaces for their functions and variables. The following is a definition for a function that can be used to easily create namespaces of any depth: I have to admit, this idea is not originally Read more…
It has been a while since I wrote a JavaScript utility function so a few minutes ago, I had the idea to create a function which will allow you to set the default value of a parameter for any given function. After writing the following function, I thought about the Read more…

While testing out jPaq v2.0 in IE6 on GoToChrisWest.com, I found an IE6 bug (go figure). The issue can be illustrated with the following code: The above code should display one thing in the alert box: toString. Unfortunately, when you run the above code in IE6, nothing is displayed to Read more…
I apologize for not writing any posts in the past few weeks, but I promise I was working hard on something big. Besides the normal work at work and my friend’s wedding, I have also been hard at work on the next version of jPaq. I still have more coding Read more…
After reviewing this page, I realized that I need to fix some of the ways that jPaq converts wildcard expressions into regular expressions. The first thing I need to do is have the @ character act as a meta-character equivalent to the + meta-character in a regular expression. The next Read more…
One of the things I had to study up on while creating jPaq was regular expressions. The reason for this is because I wanted a way for those who know how to use wildcard expressions, but not regular expressions, to be able to use equivalent regular expressions. One of the Read more…
