javascript - 删除指定元素的函数

Question

我需要创建一个函数来获取用户输入(CSS 选择器)并删除所有这些元素。这是目前为止的功能

function removeBySelector(selector) {
  var thisOne = document.querySelectorAll(selector);
  for(var i = 0; i<thisOne.length; i++) {
    document.removeChild(thisOne[0]);
  };
};

以及启动它的 HTML

<button type="button" name="button" onclick="removeBySelector(prompt('Type the selector e.g p/ p.pClass'));">Remove By Selector</button>

Answer 1

将方法更改为

function removeBySelector(selector) 
{
  var thisOne = document.querySelectorAll(selector);
  for(var i = 0; i<thisOne.length; i++) 
  {
    thisOne[i].parentNode.removeChild( thisOne[i] ); //changed parentElement to parentNode
  };
}
