Javascript直接定义对象实例[_javascript技巧

JavaScript可以不必定义对象类别而直接定义对象实例:
var person = {
name : "",
age : 0,
toString: function() {
document.writeln("[name]:"+this.name+"
"+"[age]:"+this.age);
}
}

完整的HTML例子：
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>JavaScript</title> <script language="javascript" type="text/javascript"> var person = { name : "", age : 0, toString: function() { document.writeln("[name]:"+this.name+" "+"[age]:"+this.age); } } </ script> </head> <body> <script type="text/javascript"> person.name="robbin"; person.age=30; person.toString(); </ script> </body> </html>
[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]
