使用Notepad++编程:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Json Practice</title> <script type="text/javascript"> var obj1={user:"John",age:22,country:"China"}; var obj2={user:"Mike",age:33,country:"Brazil"}; var obj3={user:"Tony",age:11,country:"Korea"}; var obj4={u1:obj1, u2:obj2, u3:obj3}; document.write(obj1.user+" is "+obj1.age+" years old "+"from "+obj1.country); obj1.country="Mexio"; document.write("<hr/>"); document.write(obj1.user+" is "+obj1.age+" years old "+"from "+obj1.country); document.write("<hr/>"); document.write(obj4.u2.name+" is "+obj4.u2.age+" years old "+" from "+obj4.u2.country); document.write("<hr/>"); document.write(obj4.u3.country); document.write("<hr/>"); document.write(obj4["u3"]["country"]); </script> </head> <body> </body> </html>
结果：
注意：注释不能用<!-- -->，不然无法显示，用//来注释，亲测。
