js 替换超链接

// 获取所有的超链接元素
var links = document.getElementsByTagName('a');

// 遍历并替换 href 属性
for (var i = 0; i < links.length; i++) {
  if (links[i].href.indexOf('old-domain.com')!== -1) {
    links[i].href = links[i].href.replace('old-domain.com', 'new-domain.com');
  }
}

// 获取包含特定文本的超链接
var oldLink = document.querySelector('a[href="http://old-link.com"]');

if (oldLink) {
  var newLink = document.createElement('a');
  newLink.href = 'http://new-link.com';
  newLink.textContent = oldLink.textContent;
  oldLink.parentNode.replaceChild(newLink, oldLink);
}
