Pop-up blockers are one of the main reasons for this error message to occur. These pop-up blockers frequently prevent some windows from appearing. The adverts from various types of websites are usually the windows that are blocked.

While the blockers are intended for such windows, they can also prevent some Java-based scripts from completing their tasks. However, if you do not want to see these error messages repeatedly, you can easily modify your pop-up blocker’s choices by going to the options and changing your pop-up blocker’s preferences.

It’s also vital to check the fine print before installing a pop-up blocker to see if it would block scripts like Java.

How to Solve the Javascript Void(0) Problem

Many internet users encounter this issue when they try to click a link and receive an error code in the browser’s status bar that prevents the link from working. Though this error message appears quite a number of times, the actual causes may differ for different people, and resolving these issues requires understanding the most common causes for this error message.

  • Problem 1: The most common source of this error message is a popup blocker that prevents JavaScript from running while also closing windows that appear as advertising on various websites.


Making changes to the popup blocker’s options based on your needs and thereby removing the popup blocker is the solution to this problem. You can either download alternative anti-popup software or read popup blocker product reviews to see whether they are genuinely causing these error messages.

  • Problem 2: Faulty web proxy servers (which are used to access certain prohibited websites) can also block numerous scripts.  


This issue can be avoided by either not utilizing the proxy server at all or by using a proxy server that works better and does not interfere with the download of various scripts. Check the proxy server’s compatibility with other websites and programs as well.

  • Problem 3: This error message could also be caused by a badly written JavaScript.


The answer is to tell the webmaster about the problem, who will then have to rewrite the JavaScript.

  • Problem 4: Your browsers’ JavaScript may be disabled, and this must be enabled.

To enable this in Internet Explorer, click to the Security tab of the Tools menu and enable the JavaScript option in Web features; to enable this in Firefox, go to the Tools menu and enable the JavaScript option in Web features.

  • Problem 5: In some circumstances, the JavaScript implementation in web browsers may be flawed.


This necessitates a change or just an upgrade to your web browser.

There is a simple way to avoid the “javascript:void(0)” error message in the first place because we know that “javascript:void(0)” can cause certain browsers to display your web pages in unusual ways, and because the “javascript:void(0)” statement is frequently encountered when a link has no URL attached to it, and the browser doesn’t know what to do and returns the error message.

To prevent the browser from looking for the URL, use the “return false;” statement instead. Find each and every “javascript:void(0)” reference within that particular page by making use of a text editor.

After that, replace the hash (#) symbol with just a “.” syntax, and you’re done. To make the complete link reference look like a Link, add the “return false” declaration to the sentence. Replace “callFunction()” with the name of your function, then save and exit the file.
