I. Classes and modules1. The implementation of the class is based on the prototype inheritance mechanism.Two. Classes and prototypesThree. Classes and constructors1. The constructor is used to initialize the newly created object.2. Use new, so the constructor simply initializes the object state.3.

(selector). At this point, Ext has pushed some common functions to the Ext object, such as Ext. element. fly to Ext. fly, Ext. domQuery. select to Ext. query, but in terms of the total amount of code, it is inferior to jQuery.KISSY combines the modular structure of Ext and introduces the problem that the function access path of Ext is too long, because the with statement in Javascript has such a problem, using aliases to replace objects with deeper l

Is there a PHP class like JavaScript that controls DOM models in HTML? I recommend a class that finds HTMLSQL, which has good functions.
