Override window.alert
For years the only bit of feedback web developers could get was via alert("{str}") calls. These days we have the web console but, in rare cases, we don't have a console and alert calls are our only window into a value at a given time.
One problem: if an alert sneaks into production code, your site looks like it's been hacked. Your site looks like it's malware! To prevent any of those issues, you can add this snippet to your production build:
window.alert = console.log
This tiny line of JavaScript could save your site from catastrophe. There are many cases for overriding native functionality and this is a great example!
![Page Visibility API]()
One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?

One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
![Image Reflection with jQuery and MooTools]()
One subtle detail that can make a big difference on any web design is the use of image reflections. Using them too often can become obnoxious but using reflections on large, "masthead" images is a classy enhancement. Unfortunately creating image reflections within your...
![Printing MooTools Accordion Items]()
Sometimes we're presented with unforeseen problems when it comes to our JavaScript effects. In this case, I'm talking about printing jQuery and MooTools accordions. Each "closed" accordion content element has its height set to 0 which means it will be hidden when the...
it’s an interesting idea, and I’m not saying the world is perfect, but if instead of using this to avoid pushing debug code onto production, how would I go about testing for stuff like alerts and other weird edge cases
In older IE browsers the browser will crash if console.log is called when the debug window is closed. Will this work then?
override window.alert in IE for logggint using $.ajax to call WebService or REST API ?
