使用Javascript从响应中删除HTML代码块

const parser = new DOMParser();
const htmlDoc = parser.parseFromString(responseText, 'text/html');

const blockToRemove = htmlDoc.getElementById('blockId');

blockToRemove.parentNode.removeChild(blockToRemove);

const xhr = new XMLHttpRequest();
xhr.open('GET', 'http://example.com/response', true);
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    const responseText = xhr.responseText;
    const parser = new DOMParser();
    const htmlDoc = parser.parseFromString(responseText, 'text/html');
    const blockToRemove = htmlDoc.getElementById('blockId');
    blockToRemove.parentNode.removeChild(blockToRemove);
    const modifiedResponse = htmlDoc.documentElement.outerHTML;
    // 处理修改后的响应内容
  }
};
xhr.send();
