jquery: Choosing a document.ready method

问题

I'm new to jquery. I've just read that these 2 are equivalent:

$(document).ready(function() {});

$(function() {});

Which one is better practice, or more accepted? The first one strikes me as clearer in that it states the "document.ready" part - but then again, I'm new to jquery. It could be that to anyone with any experience in jquery, the second option just as clearly implies "document.ready". Which of these options should I choose?

回答1:

Feel free to use either one of them. Just as you think, the latter version is a shorthand for $(document).ready().

The first option was available since the beginning of jQuery releases as oppose to the second option.

Personally I prefer the second version for it is shorter.

回答2:

All three of the following syntaxes are equivalent:

$(document).ready(handler);

$().ready(handler); //(this is not recommended)

$(handler);
