在另一个JavaScript文件中包含一个JavaScript文件

Question

I am a newbie in developing JavaScript libraries. I've a basic doubt on how to include a js file into another js file that is dependent on the former. For example, I'm building a javascript library that replicates the class structures present in the Server code.There are cases for example, where class B is contained in class A . I want to make a seperate js file to denote class B and then include this in the definition of class A . How do I go about this ?

I appreciate your help.

Thanks!

Answer 1

You can define a function in b.js which returns B class (function) and call it inside class A

b.js
getClassB function (){
    //define your B class here and return it at the end
    return B;
}

a.js
class/function A(){
    var B = getClassB();
}

Answer 2

If you are using it in html page, simply import class A file first and then class B file like

<script src="path_to_class_a_file"></script>
<script src="path_to_class_b_file"></script>
