What Does JavaScript Void(0) Mean

While opening websites, we often encounter the error JavaScript: Void (0). It primarily occurs because the internet browser is unable to read the JavaScript. Now, there are several reasons, why the internet browser fails to read the JavaScript. Let’s consider them one by one.

Popup Window Blocker

One of the foremost causes of JavaScript: Void (0) error is popup window blocker. The main function of this software is to block those windows that pop up whenever you visit a website. These windows contain promotional messages, and for a majority of internet users, they are nothing, but irritants. Popup window blocker successfully blocks the popup windows, but at times, it also prevents the JavaScript from functioning properly. This lead to JavaScript: Void (0) error.

To avoid the error from arising, either uninstall the anti popup software or change its configuration settings. Another remedy is to select some other anti popup software that effectively blocks the popup windows as well as allows the JavaScript to work accurately.

Proxy Server

Proxy servers do two things simultaneously, firstly, they allow the user to browse banned sites with ease, and secondly, they efficiently hide the true identity of the user. While executing both these jobs, these servers also block the JavaScript and cause JavaScript: Void (0) error. The best way to overcome the error is to stop using the proxy servers or switch over to those servers that do not work against the JavaScript.

Internet Browser

Sometimes JavaScript: Void (0) error occurs because of the fault of the internet browser. In some browsers the script is disabled due to which the error occurs. In such instances, you have to enable the JavaScript. If you are using Windows Internet Explorer, then to enable the script, you would have to go the Tools menu and select the Internet Options. Thereafter, you would have to click at the Security tab and choose Custom Level; check the scripting box to enable the JavaScript.

On a few occasions, upgradation of internet browser also becomes essential. The JavaScript: Void (0) error occurs because the script is written for the new browser and you are using the outdated version of the browser. In such a case, you are left with no other option than to download the latest version of the browser.

Yet another reason for JavaScript: Void (0) error is poorly written JavaScript. Here the only thing that you can do is to request the webmaster to rectify the script.
