Mastering jquery's Selector

The selector can be traced to at least the CSS selector. jquery's source code is embedded in a named Sizzle object, in fact, is the selector. In the JQuery official online show sizzle belongs to "other jQuery Foundation Projects", sizzle can be independent for a separate project, thus it is not difficult to realize the importance of the selector. Look at the following three pages, by contrast, jquery chooses the organ-side document to look the most "messy".

Http://www.w3.org/TR/css3-selectors   
CSS Selector standard document   
        
https://github.com/jquery/sizzle/wiki/ Sizzle-documentation   
Sizzle document   
        
http://api.jquery.com/category/selectors/   
jquery Select Organ side document

jquery1.9.0 source code has this line:

Jquery.find = Sizzle;

Importing Jquery.js and sizzle.js, you can see that jquery.find and sizzle are really the same thing.

Ijs.showobjectnames ("Window.jQuery.find");     
Ijs.showobjectnames ("window.") Sizzle ");

    [Object] Window.jQuery.find
        |--[function] attr
        |--[function] Compile
        |--[function] Contains
        |--[function] Error
        |--[function] GetText
        |--[function] Isxml
        |--[function] Matches
        |--[function] Matchesselector
        |--[function] Setdocument
        |--[function] Uniquesort
        |--[object] Selectors
    
    [Object] window. Sizzle
        |--[function] attr
        |--[function] Compile
        |--[function] Contains
        |--[function] Error
        |--[function] GetText
        |--[function] Isxml
        |--[function] Matches
        |--[function] Matchesselector
        |--[function] Setdocument
        |--[function] Uniquesort
        |--[object] Selectors

Since sizzle claims to be "supports virtually all CSS 3 selectors", it might be a good idea to refer to the following list of the documents and find a better piece of the document (click on the link to see the grammatical details), isn't it?

(Note: This table is always a display problem, so the HTML code is edited, one of the Replacements is (<a\shref= "[^" >]* ">) [^<]* (</a>) replaced by $ $)
