Q. What is a JavaScript error?

A. This is a very common error that you will typically get either while running an application on your computer that uses Java as a programming language, or when you are browsing a website. It simply means that there is an error in the code of the program or site and that it cannot function properly.

Q. What are the most common JavaScript errors that can occur?

A. While there are several, we’ll look at the top two that can happen. First, you may get a Java Runtime error message. This means that the program has stopped working due to an issue with the code. The program basically tries to start but when it reaches a line of code that is wrong, it can’t go any further. Second, this type of error can occur when you go to a website and get a pop up box that is filled with code. Unless you are a Java programmer, this won’t make much sense. However, it’s really nothing to worry about as a user, since the problem is not on your computer, but rather on the site you are visiting.

Q. How do I fix these errors?

A. If the problem is occurring on an application that you are personally running, it’s a good idea to close the program and restart it. If it still happens, a line of code may have become corrupted. In this case, you’ll need to uninstall the program and then reinstall it. If you continually have this error and it’s the first time you used the application, then it may just mean that the program itself is corrupt and therefore unusable. Contact the manufacturer to let them know.

If the problem happens when you are visiting a website, there really isn’t anything that you can do. In some cases, you can try closing your browser, reopening it and visiting the site again. However, the most common problem is that the site owner has an error in their code. It’s always nice to let the site owner know this is happening, since they may not be aware of it.

Until they get it fixed however, you will most likely not be able to view their page.

Q. How do I keep this from happening again?

A. While you cannot control the programming on another site, you can make sure that you are using the most recent JavaScript engine. This refers to software on your computer that makes it possible to view Java applets and programs. Go to Sun Microsystem’s site and download the latest update. This should fix the problem for you. If it is still occurring, you may also need to update your browser. It’s always a good idea to take time every month or so to make sure that you are running the latest version of your browser and Java. Most come with an automatic updater that will let you know when you need to download a new patch.
