我无法弄清楚错误是什么，错误：未捕获的 ReferenceError

Question

I can't figure out what the error is (Error: Uncaught ReferenceError)

(slidesWrapper = document.querySelector(wrapper)) - at slider

  const slides = document.querySelectorAll(slide),
    slider = document.querySelector(container),
    prev = document.querySelector(prevArrow),
    next = document.querySelector(nextArrow),
    total = document.querySelector(totalCounter),
    current = document.querySelector(currentCounter);
  (slidesWrapper = document.querySelector(wrapper));
    (width = window.getComputedStyle(slidesWrapper).width);
    (slideField = document.querySelector(field));

The data is exported to another document

Uncaught ReferenceError: slidesWrapper is not defined

slider({
    container: ".offer__slider",
    slide: ".offer__slide",
    nextArrow: ".offer__slider-next",
    prevArrow: ".offer__slider-prev",
    totalCounter: "#total",
    currentCounter: "#current",
    wrapper: ".offer__slider-wrapper",
    field: ".offer__slider-inner"
  });




  

Answer 1

You are defining multiple variables with a single const where each variable is seperated by a comma.

This is what the code should be:

const slides = document.querySelectorAll(slide),
    slider = document.querySelector(container),
    prev = document.querySelector(prevArrow),
    next = document.querySelector(nextArrow),
    total = document.querySelector(totalCounter),
    current = document.querySelector(currentCounter,
    slidesWrapper = document.querySelector(wrapper),
    width = window.getComputedStyle(slidesWrapper).width,
    slideField = document.querySelector(field);
