工廠方式構造對象：1.原料---建構函式，建立一個對象2.加工---屬性，方法3.出廠---返回結果 範例程式碼：<!DOCTYPE html><html lang="en"> <head> <title>工廠方式</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <script> function createPerson(name,sex){ //建構函式：建立一個對象 //1.原料 var obj = new Object(); //2.加工 obj.name = name; obj.sex = sex; obj.showName = function(){ alert(‘我的名字叫‘+this.name); } obj.showSex = function(){ alert(‘我是‘+this.sex+‘的‘); } //3.出廠 return obj; } var p1 = createPerson(‘sese‘,‘女‘); var p2 = createPerson(‘JJ‘,‘男‘); p1.showName(); p1.showSex(); p2.showName(); p2.showSex(); </script> </head> <body> </body></html>
工廠方式的問題：1.沒有new;2.每個對象都有一套自己的函數——浪費資源。 函數的叫法：函數：獨立的，自由的。方法：屬於一個對象的函數。事件處理函數：用於處理一個事件的函數。建構函式：建立一個對象的函數 = 類。
