如何用javascript模糊除一个元素以外的所有元素

const blurElement = document.querySelector('.blur-element');
const allElements = document.querySelectorAll(':not(.blur-element)');

.blur {
  filter: blur(5px);
}

allElements.forEach(element => {
  element.classList.remove('blur');
});

allElements.forEach(element => {
  if (element !== blurElement) {
    element.classList.add('blur');
  }
});

const blurElement = document.querySelector('.blur-element');
const allElements = document.querySelectorAll(':not(.blur-element)');

allElements.forEach(element => {
  element.classList.remove('blur');
});

allElements.forEach(element => {
  if (element !== blurElement) {
    element.classList.add('blur');
  }
});
