Support "defer" as well as "async"?

It might be nice if this could handle defer scripts as well as async, as an option.

e.g. having a consolidated interface to allow notification either type of scripts being parsed. Would allow async scripts to wait on defer ones, etc.

Yep - I guess this is a similar request to https://github.com/muicss/loadjs/issues/84 - if there’s an easy way to set those flags innately in the library, would prevent a lot of extra boilerplate needed in consumers. And should hopefully be a tiny change?

Let me think about this some more… in the mean time you can use the before callback to set the defer attribute:

loadjs(['/path/to/foo.js', '/path/to/bar.js'], {
  success: function() {},
  error: function(pathsNotFound) {},
  before: function(path, scriptEl) {
    scriptEl.setAttribute('defer', 'defer');
  }
});
