load() method deprecated?

I was browsing through the jQuery api and noticed that the load method is on the deprecated list.

Categories: Deprecated | Events > Document Loading

I usually use this method to check if images are completly loaded. Why is it deprecated? And what am I supposed to be using instead?

See bug #11733, which documents this deprecation:

The .load() method is an ambiguous signature, it can either be an ajax load or attach/fire a "load" event. CCAO cannot tell them apart since it's a dynamic decision based on arguments.

To avoid ambiguities related to the method's signature, it is now recommended to use on() instead. For instance:

$("selector").load(function() {
    // ...
});

Should become:

$("selector").on("load", function() {
    // ...
});
