Calling JavaScript Classes from other files

Hi all,

I was trying to update some of our old JScript files and was hoping to use JavaScript classes for at

least a few cases...unfortunately, I can't seem to do so.

I cannot seem to get the class to be called from another file, and looking at TestComplete documentation, the only way to do that was deprecated a while ago.

Does anyone have any examples of how to do this, or am I right in that it cannot be done?

I've tried using require and using const, but no luck. Below is a sanitized version of what I wrote.

The Class:

<SPAN class="token keyword">class</SPAN> <SPAN class="token class-name">MainClass</SPAN> <SPAN class="token punctuation">{</SPAN>
    <SPAN class="token function">constructor</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token punctuation">)</SPAN> <SPAN class="token punctuation">{</SPAN>
    <SPAN class="token punctuation">}</SPAN>
    <SPAN class="token function">Start</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token punctuation">)</SPAN> <SPAN class="token punctuation">{</SPAN>
    <SPAN class="token function">Close</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token punctuation">)</SPAN> <SPAN class="token punctuation">{</SPAN>
    <SPAN class="token punctuation">}</SPAN>    
<SPAN class="token punctuation">}</SPAN>

module<SPAN class="token punctuation">.</SPAN>exports <SPAN class="token operator">=</SPAN> <SPAN class="token punctuation">{</SPAN><SPAN class="token literal-property property">MainApp</SPAN><SPAN class="token operator">:</SPAN> MainClass<SPAN class="token punctuation">}</SPAN>

The file I'm calling it from:

<SPAN class="token keyword">var</SPAN> main <SPAN class="token operator">=</SPAN> <SPAN class="token function">require</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token string">"Main"</SPAN><SPAN class="token punctuation">)</SPAN><SPAN class="token punctuation">;</SPAN>

<SPAN class="token keyword">const</SPAN> mainApp <SPAN class="token operator">=</SPAN> <SPAN class="token keyword">new</SPAN> <SPAN class="token class-name">main<SPAN class="token punctuation">.</SPAN>MainApp</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token punctuation">)</SPAN><SPAN class="token punctuation">;</SPAN>

mainApp<SPAN class="token punctuation">.</SPAN><SPAN class="token function">Start</SPAN><SPAN class="token punctuation">(</SPAN><SPAN class="token punctuation">)</SPAN><SPAN class="token punctuation">;</SPAN>

    That does not seem to work for the Class. It does work for functions.

    Could you upload both of your codes again, as it doesn't seem to be correctly formatted.

    "That does not seem to work for the Class" - what exactly have you tried?

      Oh yeah...something really went wrong with those.

      As for what I tried...I tried exporting the class, and I've tried requiring the class. I even tried following the module format to see if that would do anything...but I got errors that the constructor could not be called.

      The Class File

      class MainClass{
          constructor() {
          }
          Start() {
          }
          Close() {
          }    
      }

      module.exports = {MainApp: MainClass}


      The file calling the class

      var main = require("Main");

      const mainApp = new main.MainApp();

      mainApp.Start();
