javascript - 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. Writing down in JavaScript console console I get the following output:

> console
Object
assert: function () {}
count: function () {}
debug: function () {}
dir: function () {}
dirxml: function () {}
error: function () {}
group: function () {}
groupEnd: function () {}
info: function () {}
log: function () {}
profile: function () {}
profileEnd: function () {}
time: function () {}
timeEnd: function () {}
trace: function () {}
warn: function () {}

I'm using Google Chrome version 13.0.782.112 on Linux.

Prototype JavaScript framework, version 1.6.0.3

Is there a quick way to solve this?

Since original console is in window.console object, try restoring window.console from iframe:

var i = document.createElement('iframe');
i.style.display = 'none';
document.body.appendChild(i);
window.console = i.contentWindow.console;
// with Chrome 60+ don't remove the child node
// i.parentNode.removeChild(i);

Works for me on Chrome 14.
