Intrinsic event attributes (like onclick) are horrible. Internally they implement with:

Use of the with statement is not recommended, as it may be the source of confusing bugs and compatibility issues.

Consequently, you are actually calling document.clear() instead of your global clear().

The quick fix for this is to rename the function to something else or explicitly call window.clear().

The better solution is to bind your event handlers with addEventListener instead of intrinsic event attributes.
