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?

Answer 1

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.

For example,

delete console.log 

would also restore console.log:

console.log = null; console.log;         // null  delete console.log; console.log;         // function log() { [native code] }
