JavaScript is currently one of the most popular web programming languages today. The original intention of the script was to allow programmers to write client-side scripts, enabling user interaction. However, since then, the popular programming language has evolved into all spheres of software development, such as games programming and application development. An IDE (Integrated Development Environment) is what is used whenever debugging and writing JavaScript code.
JavaScript errors, like so many other errors you can and may encounter on your computer system, are triggered by many different things, such as the following:
If you don’t want to be pestered with repeated JavaScript error messages or the yellow error icon, it is possible for you to disable warnings, in Internet Explorer. To do this, simply do the following:
Error Type: Random Application Glitch
Solution: If you’re greeted with a Void 0 error message, then it’s recommended that you restart your system, and then attempt to run the application again.
Error Type: JavaScript Web Implementation Broken
Solution: If you experience the JavaScript error message right after the installation of a browser extension or the browser itself, then that’s a strong indication of a poor or damaged installation. In order to fix this problem, you will need to reinstall the extension or browser. Just be sure to uninstall the application before you reinstall it.
Error Type: Registry Error
Solution: If after attempting all of the above solutions, for the various JavaScript errors, you’re still getting the Void 0 error message, then it’s likely the result of a conflict within the Windows registry.
The exact cause of the error may be due to a corrupted, invalid or missing registry key(s). To fix the problem, you will need to reconfigure the registry key(s), which can be a very complex task, not to mention, dangerous, as deleting the wrong registry key is capable of rendering your system inoperable.
That said, the best way for you to fix or repair issues with the registry is to use a registry cleaner tool, there are many of these tools around, some paid others free, I suggest you try a free one first.
Error Type: The vital components of JavaScript had been disabled
Solution: One thing you should be aware of is that the following components, Java applets, ActiveX Controls and Active Scripting are all essential to JavaScript for it to run correctly on your browser. If all three of these components are disabled, it can and does occasionally result in a JavaScript Void (0) error message.
Fixing the problem is fair, using the instructions on Disable Active Script Debugging, simply locate and Enable JavaScript.
What Causes JavaScript Errors?
JavaScript errors, like so many other errors you can and may encounter on your computer system, are triggered by many different things, such as the following:
- A random application glitch causing it to crash.
- The user visits a website that contains malicious files.
- The Windows registry being corrupted by a third-party application.
- JavaScript implementation on the web browser is broken due to a corrupted install.
- If when attempting to load a website in Internet Explorer you encounter the yellow icon, your next cause of action should be to double click on it. By doing this, it will provide you with additional information on the cause of the error, such as the particular line of code.
- Once you know which line(s) of code in the website is incorrect, you can open a JavaScript or HTML editor and make the necessary changes. Usually it’ll be something simple, i.e. a semicolon in the wrong place.
Disable Active Script Debugging
If you don’t want to be pestered with repeated JavaScript error messages or the yellow error icon, it is possible for you to disable warnings, in Internet Explorer. To do this, simply do the following:
