Why Does My IE JavaScript Only Work After Opening Developer Tools?

IE JavaScript Enigma: Only Works After Opening Developer Tools

Despite encountering numerous issues on various browsers, the peculiar behavior observed in Internet Explorer stands out. In this instance, JavaScript remains inoperative until the developer tools are initiated with F12. While this workaround temporarily resolves the issue, a thorough understanding of the underlying cause is essential.

Debugging Wonder or Debugging Foil?

The observed behavior suggests the presence of debugging code within the JavaScript. More specifically, calls to console.log() or other console functions may be the culprit. The console object in IE remains inactive until the developer toolbar is activated. Attempting to invoke the console object prior to this activation results in an "undefined" error. However, once the toolbar has been invoked, the console is established, rendering subsequent console calls operable.

Resolving the Enigma

To address this issue, several solutions are at your disposal:

  • Console Cleanup: Meticulously review your code, removing any references to console. As a general principle, debugging code should not be incorporated into production code.
  • Conditional Invocation: Consider wrapping your console references within an if() statement or other conditional construct. This ensures that the console object is present before attempting to invoke it.
