Restoring console.log()

Question

For some reason, the prototype framework (or another JavaScript code) that is shipped with Magento is replacing standard console functions, so I can\'t debug anything. Writi

Answer 1

function restoreConsole() {
  // Create an iframe for start a new console session
  var iframe = document.createElement('iframe');
  // Hide iframe
  iframe.style.display = 'none';
  // Inject iframe on body document
  document.body.appendChild(iframe);
  // Reassign the global variable console with the new console session of the iframe 
  console = iframe.contentWindow.console;
  window.console = console;
  // Don't remove the iframe or console session will be closed
}
