Passing value from one function to another class function using javascript / node js-CodePudding

I am trying to pass value from one page function to another Class function but its not working as expectation

detail.js

const {UserData} = require("./userData");

let commonfield="Asia Origin";

var userData= new UserData();
userData.start(commonField);

userData.js

class UserData extends Commands{
 async start(field){
  console.log(field);
 }
}

Here You can see I tried to pass the value but its not passing the value from detail.js to userData.js class function

CodePudding user response：

You are calling the wrong function:

const {UserData} = require("./userData");

let commonfield="Asia Origin";

var userData= new UserData();

try {
   const result = await userData.start(commonField); // should be start
} 
catch(e) {
   console.log(e);
}

class UserData extends Commands{
 async start(field){
  console.log(field);
  return field;
 }
}

As, start is an async function to get its value you need to use await.

CodePudding user response：

can you remove 'async; and then check it ? i hope, it should be a work.
if not try this way...
const UserData = require("./userData.js");
let commonfield="Asia Origin";
new UserData().save("values printed");
UserData.js
class UserData extends Commands{
 start(field){
  console.log(field);
 }
}
Commands.js
Class Commands{
fun(){console.log("abc");}
