Pseudo JavaScript Console

Netscape has a handy feature called the JavaScript Console, which allows direct input of JavaScript statements displays any error messages. This is very valuable for debugging and experimentation.

This page attempts to provide at least part of that functionality in Internet Explorer and other non-Netscape browsers. Just use the form above to type in some code and try running it.

Warning: be careful what you type. Some JavaScript code can cause problems for browsers.
