As I was writing jPaq v2.0, one of the things I wanted in quite a few cases were functions in which the this object could be parameterized without using the theFunction.apply() function or the theFunction.call(). Here is an example of what is often done with native prototypal functions: Even though, Read more…
Have you ever had to work with a spreadsheet which contained a column full of dates, but you actually needed to see column full of the corresponding days of the week by name? Believe it or not, translating dates to the name of the day of the week is quite Read more…
At times, I have had to add commas to numbers in order to make them look better in different applications. Even though there isn’t a native way to do this in JavaScript, the code can be quite short, sweet and to the point: The downside of the above function is 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…
Most people that have written JavaScript realize that the and operator is && and the or operator is ||. Did you know, though, that these operators are short-circuit operators?

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…
Working Solution – Custom Function I have to say that using PostgreSQL has been great compared to MySQL. Recently, though, I ran into an issue while working with iReports designer. I needed to be able to accept a string of comma-delimited integers and then JOIN on those ID’s. Therefore, I Read more…
Two of the most widely used JavaScript functions that are now deprecated are the escape() and unescape() functions. This means that in order to ensure that your code will continue to work in all future browsers, you should use one of the alternative functions as was indicated on MDN: encodeURI() Read more…
