在vanilla js中选择<a>选项时如何更改<select> href

const selectElement = document.querySelector('select');
const linkElement = document.querySelector('a');

selectElement.addEventListener('change', function() {
  // 在这里执行更改<a>元素href属性的操作
});

const selectedIndex = selectElement.selectedIndex;
const selectedOption = selectElement.options[selectedIndex];
const optionValue = selectedOption.value;
const optionText = selectedOption.text;

linkElement.setAttribute('href', optionValue);

const selectElement = document.querySelector('select');
const linkElement = document.querySelector('a');

selectElement.addEventListener('change', function() {
  const selectedIndex = selectElement.selectedIndex;
  const selectedOption = selectElement.options[selectedIndex];
  const optionValue = selectedOption.value;
  
  linkElement.setAttribute('href', optionValue);
});
