How to Enable JavaScript Errors in IE

By Chris Hoffman

Internet Explorer runs JavaScript files embedded on Web pages. JavaScript files are small programs written in the JavaScript programming language. Errors in JavaScript files can cause problems on Web pages. If you're debugging a Web page or a JavaScript file, you can enable the script debugger feature in Internet Explorer. The debugger provides detailed JavaScript error messages that appear when errors occur on Web pages. This feature is disabled by default.

Click the gear icon near the top-right corner of the Internet Explorer window and click "Internet Options."

Click the "Advanced" tab at the top of the Internet Options window.

Scroll down to the "Browsing" section in the list of advanced options.

Uncheck the "Disable Script Debugging (Internet Explorer)" check box by clicking it.

Click "OK."
