It occurs to me that I have neglected to post about the most bloody useful utility I’ve ever written:
While the main version is a jQuery plugin, I find myself using the non-jQuery version more often, so that’s the one I’ll describe here.
doWhen does is allow you to create a single “virtual event” in the form of a test function which, when it returns
true, runs a callback function.
Let’s say we were loading a library and wanted a quick way to do something when the library is ready:
!! ensures the result is a
boolean. Every 100 milliseconds (configurable), it will run the first function. The first time that function returns
true, it runs the second function.
I use this extremely frequently, even in wee code snippets, thanks to the tiny footprint (about 1/3kB minified).
See the github page for options.
Open question: is Event the place to put this? Keep in mind this isn’t extending the object’s prototype, so shouldn’t cause conflicts in other code.
I am considering whether there’s a need for an ajax capable one which periodically checks a remote state.
