Small javascript utility to wait for jquery or other libraries to load before executing functions.
The most likely use case for this is if you are using a cms which loads a library such as jQuery near the end of the body tag, and the javascript you need to execute comes before that definition (ie. in a blog post).
###How to Use
By default this utility waits for jQuery, however you can pass a string as the first argument to wait for whatever variable you want.
Default:
wfi(function(){
console.log('jQuery is now defined');
});
Example waiting for angular to be defined:
wfi('angular', function(){
console.log('angular is now defined, do stuff');
});You can pass multiple functions, they will get called in succession:
wfi('angular',
function(){
console.log('angular is now defined, do stuff');
},
function(){
console.log('do some more stuff after that');
}
);
