Javascript Errors

Javascript is a type of programming language, intended for cross-platform application development. We encounter Javascript every day when we use our computers, because it is an important part of many of the websites that we visit. Javascript is used for many different elements of websites, including menus, and embedded video and music players. If you have ever encountered a situation where a special function of a website such as the ones mentioned above didn't work, the issue was most likely caused by a Javascript error. Javascript errors can be resolved with a few very simple steps, which will be described in this article. The steps are as follows:

1. Download the latest Java Runtime Environment
2. Check for any updates for Windows or your web browser.
3. Check for malware or a browser hijack.
4. Scan for and correct registry issues.

1. Downloading Java Runtime Environment

Downloading the most recent Java Runtime Environment is as simple as visiting http://www.java.com. Click on the large blue button titled "Free Java Download" to be walked through the remainder of the process. Downloading the most recent Java Runtime Environment will resolve the vast majority of all Javascript issues that may be encountered.

2. Checking for Windows and web browser updates

If you have the most recent Java Runtime Envrionment installed and this has not resolved your issue, there may be an incompatibility with an older version of Windows, or your web browser, at fault. To check for Windows updates, visit http://windowsupdate.microsoft.com. Please note that Windows Update only works with the Internet Explorer web browser. If Internet Explorer is your primary web browser, these updates are also available through the Windows Update website. Updates for Firefox may be downloaded from http://www.mozilla.com.

3. Checking for malware or browser hijacks

Some types of Javascript errors can be caused by malware. Malware can be installed on the computer without your knowledge or permission when you visit a website that has been hacked, or if rogue software is accidentally installed. Malware can include any type of malicious software such as viruses, adware, spyware, and Trojan horses. The most common purpose of malware is to watch a user's keystrokes or browsing habits, often for nefarious purposes such as identity theft. Often, malware can be clumsily programmed, and cause everything from the improper display of websites due to Javascript errors, to complete crashes of Windows. Checking for and removing malware can both resolve Javascript errors, and protect your personal data as well. A list of popular malware removal solutions and their download locations appears below:

• Nod32: http://www.eset.com
• Kaspersky: http://www.kaspersky.com

4. Scanning for and resolving registry issues

There are a number of different reasons why Javascript errors could result from issues with the Windows registry. The registry contains important information about your personal Windows configuration, and it is vital to the operating system and to many of the programs that you run. Over time, as programs are installed and later uninstalled, many things that are added to the registry are not properly removed. This can result in the registry ballooning to many times its original size, which causes the computer to run slowly, and many programs to run improperly, including the web browser. If all of the steps above have been attempted, and you are still encountering Javascript errors, scanning for registry problems may resolve the issue. CCleaner is an extremely popular registry scanner that is free. While scanning for and correcting problems with the registry, it will also scan the hard drive for files that are no longer being used and can be deleted to reclaim hard drive space. CCleaner can be downloaded from http://www.ccleaner.com.

After completing these steps, any Javascript issues that you have encountered should be resolved, enabling you to use all of the special functions of your favorite websites.
