Javascript对象,表现方式一:
1 person = new Object(); 2 person.firstname = "An"; 3 person.lastname = "na"; 4 person.age = 12; 5 alert(person.age);
Javascript对象,表现方式二:
1 function person(firstname, lastname, age) { 2 this.firstname = firstname; 3 this.lastname = lastname; 4 this.age = age; 5 } 6 var newPerson = new person("An", "na", 12); 7 alert(newPerson.firstname)
Javascript对象,表现方式三:
1 var person = { firstname: "An", lastname: "na", age: 12 }; 2 alert(person.firstname);
Jquery扩展简单,简单应用如下:
1 <!DOCTYPE html> 2 3 <html lang="en" xmlns="http://www.w3.org/1999/xhtml"> 4 <head> 5 <meta charset="utf-8" /> 6 <title></title> 7 <script type="text/javascript" src="jquery-1.7.1.min.js"></script> 8 <script type="text/javascript"> 9 //jquery 扩展: 10 jQuery.extend({ 11 my: function () { 12 alert("初试jquery扩展"); 13 } 14 })(jQuery); 15 //使用: 16 $.my(); 17 18 //jquery对象扩展: 19 jQuery.fn.extend({ 20 self: function () { 21 alert("jquery对象扩展"); 22 } 23 }) 24 //使用: 25 $("span").self();//需要用对象. 26 </script> 27 </head> 28 <body> 29 <span>jquery对象扩展</span> 30 </body> 31 </html>
