Firebug is a useful Firefox extension to debug JavaScript and more. To not raise error messages on browsers without
|
||
|
|
Firebug, there's a small script called [firebugx.js](http://getfirebug.com/firebug/firebugx.js), which creates empty
|
||
|
|
functions. [Sascha Hameister](http://javascript.io/index.php?/archives/42-Kleiner-Performance-Patch-fuer-firebugx.js.html)
|
||
|
|
has optimized this script a little bit and it now looks like this:
|
||
|
|
|
||
|
|
{% highlight javascript %}
|
||
|
|
// FirebugX for browsers without Firebug
|
||
|
|
if (!window.console || !console.firebug) {
|
||
|
|
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml", "trace",
|
||
|
|
"group", "groupCollapsed", "groupEnd", "time", "timeEnd", "profile", "profileEnd", "count"];
|
||
|
|
|
||
|
|
var emptyFunction = function() {};
|
||
|
|
|
||
|
|
window.console = {};
|
||
|
|
for (var i = 0, count = names.length; i < count; ++i) {
|
||
|
|
window.console[names[i]] = emptyFunction;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
{% endhighlight %}
|
||
|
