Question

我在this site上创建了一个自定义复选框，我正在尝试将它与tabindex一起使用，但我知道这个CSS使用的return request .then(result => { console.log(result); return result; }) .catch(error => { console.error(error); throw error; });并不允许使用taborder，所以这是我的问题：如何在保留输入属性的同时在表单中使用此自定义复选框？

Answer 1

您可以将tabindex附加到代表该复选框的标签，然后将键盘事件附加到标签，以便在按下某个键时切换复选框。在这个例子中，我在用户按下空格键时切换它，就像真正的复选框一样。

var checkbox = document.getElementById('myonoffswitch'),
  label = document.querySelector('#myonoffswitch + label');


label.addEventListener('keypress', function (evt) {
  if (evt.key === ' ') {
    checkbox.checked = !checkbox.checked;
  } else if (evt.key === 'Enter') {
    // .form returns a reference to the parent form
    checkbox.form.submit();
  }
}, false);
