為什麼 console.log 在 IE8 最終版本中消失？

IE8's Hide-and-Seek Console.log

The absence of console.log in the final release of IE8 has perplexed developers, given its presence in the beta. The discrepancy stems from the fact that console.log is only accessible through the Developer Tools panel.

Unveiling the Console.log

To enable console.log, simply toggle the Developer Tools panel using F12. Surprisingly, it remains functional even after closing the panel.

Addressing the Quirky Behavior

This apparent bug may leave developers wondering if it will be fixed. While no definite answer exists, the bug may persist.

Workarounds for Debugging

To circumvent the console.log limitations, developers can employ the following workarounds:

• Function trace:

function trace(s) {
  if ('console' in self && 'log' in console) console.log(s)
  // Uncomment the line below to receive silent notifications instead
  // of alert pop-ups.
  // else alert(s)
}

• Simplified function:

function trace(s) {
  try { console.log(s) } catch (e) { alert(s) }
}

These workarounds allow developers to write debugging statements without relying solely on the console.log function.
