从函数更新标签文本的正确方式是什么?

从函数更新标签文本的正确方式是使用DOM操作来更新标签的textContent或innerHTML属性。通过获取到需要更新的标签元素,可以使用JavaScript中的DOM操作方法来修改标签的文本内容。

具体步骤如下:

  1. 使用document.getElementById()、document.querySelector()等方法获取到需要更新的标签元素,可以通过元素的id、class、标签名等方式进行选择。
  2. 使用textContent属性来更新标签的纯文本内容,例如:element.textContent = "新的文本内容"。
  3. 使用innerHTML属性来更新标签的HTML内容,例如:element.innerHTML = "<b>加粗文本</b>"。

更新标签文本的正确方式可以保证页面的内容正确显示,并且避免了直接操作HTML字符串带来的安全风险。
