javascript - Be notified when the Android soft-keyboard is collapsed on web page

Question

We have a text input that shows suggestions when we enter values into it. The input value should be reset when the input field loses focus:

const input = document.querySelector('#input');
const suggestions = document.querySelector('#suggestions');

const items = [
  "test",
  "test-2",
  "some-other-value",
  "etc",
  "more suggestions"
];

function getListItem(item) {
  return `<li>${item}</li>`;
}

input.addEventListener('input', filter);
input.addEventListener('focusout', (event) => {
  event.target.value = "";
  filter(event);
});

function filter(event) {
  const value = event.target.value;
  const filteredSuggestions = items.filter(item => item.includes(value.toLowerCase()));
  let htmlContent = '';
  for (const item of filteredSuggestions) {
    htmlContent += getListItem(item);
  }
  suggestions.innerHTML = htmlContent;
};

<input id="input" />
<ul id="suggestions">
</ul>
