HTMLSelectElement.remove()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

HTMLSelectElement.remove() 方法从一个 select 元素中删除指定序数的 option 元素。没有传参时为删除当前元素本身:ChildNode.remove()

语法

js
remove(index)

参数

  • index 是从 option HTMLOptionElement 集合中要移除元素的序数。如果序数对应的元素不存在,调用这个方法就没有任何效果。

例子

js
var sel = document.getElementById("existingList");
sel.remove(1);

/*
  上面的代码会将下面的 select 元素结构:

  <select id="existingList" name="existingList">
    <option value="1">Option: Value 1</option>
    <option value="2">Option: Value 2</option>
    <option value="3">Option: Value 3</option>
  </select>

  变成这样:

  <select id="existingList" name="existingList">
    <option value="1">Option: Value 1</option>
    <option value="3">Option: Value 3</option>
  </select>
*/
