Dependency-free JavaScript onLoad

Question

I'm working on a JavaScript library which needs to give the user the ability to run some code on load. Of course, I'm familiar with window.onload, and things like $(function() {}); with jQuery. But I don't want to be dependent on another library, and I want this particular function (along with the rest of the lib, of course) to be cross-browser.

So is there an accepted way of attaching to the onload function without overriding another library's load functionality (or having mine overwritten if they include another lib after mine)?

Answer 1

Expose an initialization/onload method and require it be called by the consumer on load. In other words, push the issue off to whomever is using the library and will likely have a convenient method like that offered by jQuery.

This is a solved problem but it isn't simple: the answer to "$(document).ready equivalent without jQuery" has the code of how jQuery does this.
