jquery's API official Web site is: http://api.jquery.com, this should be the most authoritative (I recommend this to see)
If the speed, or the English level is not enough to force, you can search Chinese web pages,
For example, I found this page: Http://www.css88.com/jqueryapi probably translated the jquery official document
Documents, after all, are documents, but when they are actually applied, they are real.
Today, take the development environment of the Machine (ie/firefox/safari/chrome) did a measurement (jQuery1.9.0), recorded as follows:
