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!
![Create Namespaced Classes with MooTools]()
MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does. Many developers create their classes as globals which is generally frowned up. I mostly disagree with that stance, but each to their own. In any event...
![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?
![Introducing LazyLoad 2.0]()
While improvements in browsers means more cool APIs for us to play with, it also means we need to maintain existing code. With Firefox 4's release came news that my MooTools LazyLoad plugin was not intercepting image loading -- the images were loading regardless of...
![Dynamic Waveform Visualizations with wavesurfer.js]()
Waveform images are an awesome addition to boring audio widgets. They can be functional as well as aesthetically pleasing, allowing users to navigate audio visually. I recently found wavesurfer.js, an amazing waveform image utility that uses to Web Audio API to create super customizable...
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 ?
