JavaScript学习总结(十四)——JavaScript编写类的扩展方法

在​J​a​v​a​S​c​r​i​p​t​中​可以使​用​类的p​r​o​t​o​t​y​p​e属性来​扩​展​类的属​性​和​方​法,在实际开发当中,当JavaScript内置的那些类所提供的动态方法和动态属性不满足我们实际开发时,我们就可以通过"prototype"属性给自定义类添加方法和属性或者扩展原有的类中的方法和属性。

一、扩展JavaScript内置类,添加动态方法

语法格式:

  类名.prototype.方法名 = function([param1],[param2],....[paramn]) {

    .................

  }

  [param1],[param2],....[paramn]这些参数都是可选的

  使用这种方式给类添加的扩展方法都是动态的,动态方法是针对类的实例对象的,所以调用必须要用"对象.方法名"的形式去调用,不能用"类名.方法名"的形式去调用!

1.1、使用prototype属性扩展String类

  String类是JavaScript内置的一个类,但是这个String类没有quote方法,此时就可以使用String类的prototype属性去扩展String类了,为String类添加一个实例方法(动态方法),这样每一个String类对象就都有quote方法了,这就达到了将String类扩展的效果,增强了String类的使用。

1 /*扩展为String类,为String类增加quote(两边加字符)方法*/
2 String.prototype.quote = function(quotestr) {
3 if (!quotestr) {
4 quotestr = "\"";
5 }
6 return quotestr + this + quotestr;
7 };

测试String类新添加的quote方法

1 alert("abc".quote());
2 alert("abc".quote("|"));

1.2、使用prototype扩展Number类

1 Number.prototype.add=function(n){
2 //哪个对象调用this所在的函数,那么this代表的就是哪个对象实例
3 return this+n;
4 }

测试Number类新添加的add方法

1 var i= new Number(10);//等价于var i=10;
2 alert("i.Add(10).Add(30)的结果是:"+i.Add(10).Add(30));
3 var b=40;
4 alert("b.Add(90)的结果是:"+b.Add(90));

测试结果:

1.3、使用prototype扩展Array类

 1 Array.prototype.findVal=function(val){
2 var index=-1;
3 //哪个对象调用this所在的函数,那么this代表的就是哪个对象实例
4 for(var i=0;i<this.length;i++){
5 if(val==this[i]){
6 index=i;
7 break;
8 }
9 }
10 return index;
11 }

测试Array类新添加的findVal方法

1 var arr = new Array();
2 arr[0]="孤傲苍狼";
3 arr[1]="白虎神皇";
4 arr[2]="灭世魔尊";
5 alert("arr.FindVal(\"白虎神皇\")返回的索引是:"+arr.FindVal("白虎神皇"));

  以上三个小例子就是使用类的prototype属性扩展了String类,Number类,Array类,分别给这三个类添加了本身不存在的quote,add,findVal方法,JavaScript所有的类都可以使用prototype去扩展,当觉得类本身提供的方法和属性不满足实际应用需求时,就可以根据需要进行扩展,为类添加新的方法和属性,增强类的使用功能!

二、扩展JavaScript内置类,添加静态方法

  JavaScript是可以给类添加静态的扩展方法的,语法格式如下:

  类名.方法名 = function([param1],[param2],....[paramn]) {

    .................

  }

  [param1],[param2],....[paramn]这些参数都是可选的

  使用这种方式给类添加的扩展方法都是静态的,动态方法是针对类的实例对象的,所以调用必须要用"对象.方法名"的形式去调用,而静态方法是针对类的,用"类名.方法名"的形式去调用!

  C#中的String类有一个静态的Format方法非常强大,在拼接字符串时特别方便,JavaScript的String类并没有Format方法,但是我们可以去扩展String类,为String类添加类似C#中的String类的静态的Format方法

范例:扩展String类,添加Format静态方法,模仿C#中的String.Format方法

 1 // ----------------------------------------------------------------------
2 // <summary>
3 // 扩展String类,添加Format静态方法,模仿C#中的String.Format方法
4 // </summary>
5 // <returns>str</returns>
6 // ----------------------------------------------------------------------
7 if (!String.Format) {
8 String.Format = function () {
9 if (arguments.length == 0) {
10 return null;
11 }
12 var str = arguments[0];
13 if (arguments[1] instanceof Array) {
14 var arr = arguments[1];
15 for (var i = 0; i < arr.length; i++) {
16 var re = new RegExp('\\{' + i + '\\}', 'gm');
17 str = str.replace(re, arr[i]);
18 }
19 } else {
20 for (var i = 1; i < arguments.length; i++) {
21 var re = new RegExp('\\{' + (i - 1) + '\\}', 'gm');
22 str = str.replace(re, arguments[i]);
23
24 }
25 }
26 return str;
27 }
28 }

测试为String类扩展的Format静态方法

1 var str="我是{0},我在总结{1}和{2}的学习,我很喜欢{3}这2门语言!";
2 //使用"类名.方法名"的形式去调用类的静态方法
3 str = String.Format(str,"孤傲苍狼","java","JavaScript","'java'和'JavaScript'");//把str中的占位符{0},{1},{2},{3}用具体的内容替换掉
4 alert(str);

运行结果:

  这个小例子就是扩展了String类,给String类添加了一个静态的Format方法,JavaScript所有的类都可以添加静态扩展方法,当觉得类本身提供的静态方法和静态属性不满足实际应用需求时,就可以根据需要进行扩展,为类添加新的静态方法和静态属性,增强类的使用功能!

  以上就是对JavaScript编写类的扩展方法的总结,大家可以根据实际情况对JavaScript内置的那些类编写扩展方法,满足在开发中实际需求!有一个比较著名的prototype.js库就是针对JavaScript内置的那些类进行扩展,编写了大量的扩展方法!学习编写JavaScript扩展方法时,可以去多多参考prototype.js的写法,我本人现在也在看prototype.js的源码,过段时间再和大家分享我的心得吧!文章中如果有写得不对的地方,欢迎朋友们指正,感激不尽!
