javascript篇：javascript对象

此系列文章记录javascript的内置对象,包含内容如下(参照W3School的介绍来做的笔记)：

• Array
• Boolean
• Date
• Math
• Number
• String
• RegExp
• Functions
• Events
• Window系列，DOM系列

　　javascript对象大多包含一个constructor属性，返回对应的函数对象的引用,这有时候会有点小用处呢：

 1 <script type="text/javascript">
 2
 3 var test=new Array();
 4
 5 if (test.constructor==Array)
 6 {
 7 document.write("This is an Array");
 8 }
 9 if (test.constructor==Boolean)
10 {
11 document.write("This is a Boolean");
12 }
13 if (test.constructor==Date)
14 {
15 document.write("This is a Date");
16 }
17 if (test.constructor==String)
18 {
19 document.write("This is a String");
20 }
21
22 </script>

 1 <script type="text/javascript">
 2
 3 function employee(name,job,born)
 4 {
 5 this.name=name;
 6 this.job=job;
 7 this.born=born;
 8 }
 9
10 var bill=new employee("Bill Gates","Engineer",1985);
11
12 document.write(bill.constructor);
13
14 </script>
