从父 Scope 访问变量的外部函数

Question

I have a block of code that looks something like this:

const $ = prototype;

(function($){

    myFunc();

})(jQuery)

const myFunc = function () {

    console.log($);

}

In this situation the output is going to be prototype . But I want any child functions to have $ as jQuery. Bear in mind that the functions have many children.

I could pass $ as a parameter, or I could define a new local const in each child function. Is there any way that I can avoid this and make $ = jQuery available to all child functions?

Answer 1

maybe you are looking for something like this

    var previous = null;
var current = null;

const myFunc = function () {

  console.log($);
  console.log(this.v)
  childfunc()

}
const childfunc = function(){
  var $=this.v
  console.log($)     
  childofchild()
}
const childofchild = function(){
  var $=this.v
  console.log($)
}

const $ = 'prototype';

(function($){
  v=$
    myFunc();

})('jQuery');
