JavaScript Object-Oriented programming

bad wording.

 function createperson(name,qq) {//Constructors    /* The new constructor will automatically be the new Object object, var this = new object ();     Finally, the new this object is returned, return this; */     This. name=name;//Property name     This. qq=qq;//Properties QQ     This. showname= function() {Alert (' My name is: '+ This. name); } This. showqq= function() {Alert (' My QQ number is: '+ This. QQ); }}varobj=NewCreateperson (' user1 ',' 1234 ');varObj2=NewCreateperson (' User2 ',' 5678 ') alert (Obj.showname = = Obj2.showname);//false/* The showname of the two new build objects are different for new objects, and memory consumption is affected by excessive performance. * /

good wording.

 function createperson(name,qq) {//Constructors     This. name=name;//Property name     This. qq=qq;//Properties QQ}createperson.propotype.showname= function() {Alert (' My name is: '+ This. name);} createperson.propotype.showqq= function() {Alert (' My QQ number is: '+ This. QQ);}varobj=NewCreateperson (' user1 ',' 1234 ');varObj2=NewCreateperson (' User2 ',' 5678 ') alert (Obj.showname = = Obj2.showname);//true/ * At this point the two obj showname are the same * /

Object-Oriented Programming : Add attributes (variables) with constructors, and use prototypes to add methods (functions).
into the prototype, and put it in the constructor differently. Because name, QQ is indeterminate, and the method shown is the same.

Object- oriented : When working with objects, focus only on the functionality provided by the object, without paying attention to its internal details, such as jquery

CSS		JavaScript
Class	Add to a group of elements at once	Prototype
Style	Add to one element at a time	A method to add to an object

A prototype is equivalent to a class in CSS, adds to a set of elements, and can inherit a common

varnewArray（）；

class	Object
Mold	Products (finished)
Array ()	Arr
Can be new Array ()	Do not use new arr ()
Array is a die, does not have the actual function, cannot array.push ()	ARR is a product that is brought to use and can be Arr.push ()
Classes have prototypes that can be Array.prototype	Object has no prototype and cannot be Arr.prototype
