代碼不起作用。切換應該可以作業，但它不會呼叫類。開發者選項沒有給我任何線索-有解無憂

**此代碼不起作用我已將所有 js 檔案包含在代碼中，但登錄切換仍然不起作用。甚至開發人員選項也沒有給我們任何線索。

uj5u.com熱心網友回復：

你應該在加載 jQuery 并且 dom 準備好時附加點擊處理程式，即$(function(){ ... here ... });.
toggleclass實際上是toggleClass。
of 的引數toggleClass是類名navbar-tab--open而不是類選擇器.navbar-tab--open，所以它是toggleClass('navbar-tab--open')。

$(function(){
  $('.navbar-toggle').click(() => {
    $('.navbartab').toggleClass('navbar-tab--open');
  })
});
