如何让脚本打开页面？

const inputs = document.querySelectorAll('input');

const obj = {
  a: {
    path: '',
    isChecked: false
  },
  b: {
    path: '',
    isChecked: false
  },
  c: {
    path: '',
    isChecked: false
  },
}

inputs.forEach(addListener);

function addListener(input) {
  input.addEventListener('click', onClickHandler);
}

function onClickHandler(e) {
  changeObjectValues(obj[e.target.name], e.target.value, true);
  const checkedInputs = getСlosestCheckedInputs(e.target);

  if (checkedInputs.length > 0) uncheckInputs(checkedInputs);

  if (isAllChecked()) {
    const url = 'https://site.ru' + Object.keys(obj).map(getPath).join('');
    alert(url);
  }
}

function getPath(key) {
  return obj[key].path;
}

function isAllChecked() {
  return Object.keys(obj).every(isChecked);
}

function isChecked(key) {
  return obj[key].isChecked === true;
}

function changeObjectValues(obj, path, isChecked) {
  obj.path = path;
  obj.isChecked = isChecked;
}

function getСlosestCheckedInputs(target) {
  const inputs = target.parentNode.parentNode.querySelectorAll('input[type="checkbox"]');
  const checkedInputs = [];

  inputs.forEach(function getCheckedInput(input) {
    if (input.checked && input != target) checkedInputs.push(input);
  });

  return checkedInputs;
}

function uncheckInputs(checkedInputs) {
  checkedInputs.forEach(function uncheck(input) {
    input.checked = false;
  })
}
