下拉列表从列表中删除空白项

嗯,这很难说明

这个密码怎么样?

HTML格式

  <% sort_options = [{text: "Text0", id: 0}, {text: "Text1", id: 1}] %>
  <%= select_tag id='dropdown_sorter_tag', options_for_select(sort_options.collect{ |k| [k[:text], k[:id]] }, sort_options.collect{ |k| [k[:text], k[:id]] }[2]), include_blank: true %>

const selectElement = document.querySelector('#dropdown_sorter_tag')

selectElement.addEventListener('change', (e) => {
  if (!selectElement.value) {
    return
  }
  const options = selectElement.querySelectorAll('option')
  for (let i = 0; i < options.length; i += 1) {
    if (options[i].value) {
      continue
    }
    options[i].remove()
  }
})
