在另一个Javascript文件中包含Javascript文件

[英]Including Javascript file inside another Javascript file

I have two classes, say ParentClass and ChildClass in 2 separate files. 我有两个类,分别在2个单独的文件中说ParentClassChildClass I am directly invoking a function inside ChildClass and I want to include the ParentClass dynamically when the ChildClass is invoked. 我直接在ChildClass内部调用一个函数,并且想在调用ChildClass时动态包含ParentClass I DON'T want to use any external library or packages such as jQuery , require.js etc. Also I DON'T want to use ES6 or nodejs require as said here , because of browser compatibility issues. 希望使用任何外部库或包jQueryrequire.js等。此外,我希望使用ES6nodejs require为说这里的,因为浏览器兼容性问题。


Here is how my files looks like, 这是我的文件的样子,

parentclass.js parentclass.js

var ParentClass = function(param1, param2) {
    // Class related code here
};

ParentClass.prototype.parentClassFunction = function() {
     // Code for the function here...
};

childclass.js childclass.js

var ChildClass = function(param1, param2) {
    // Some class related code here...

    this.parentClassFunction();

    // Some other code...
};

ChildClass.prototype = Object.create(ParentClass.prototype);

HTML file HTML文件

.....
<head>
  ...
  <script src="childclass.js"></script>
  ...
</head>
<body>
  ...
  <script>
    var value = new ChildClass(10, 20);
  </script>
  ...
</body>

Is there any way by which I can achieve this? 有什么办法可以实现这一目标? Your help is appreciated. 感谢您的帮助。

Thanks in advance. 提前致谢。 :) :)

NOTE : I had a brief look into this , this and this question. 注意 :我对这个这个这个问题做了简短的研究。

Best option is to bundle all the files with a precompiler or something like that. 最好的选择是将所有文件与预编译器或类似的东西捆绑在一起。

in your childclass.js you should use require('parentclass.js') or import use something like Browserify to solve the dependencies automagically. 在childclass.js中,您应该使用require('parentclass.js')或import使用类似Browserify之类的方法自动解决依赖关系。

If you are use ES6 features you can use import: 如果您使用的是ES6功能,则可以使用导入:

for example: 例如:

import { Childclass } from '/path/to/childclass';

Here is the documentation for import: 这是要导入的文档:
