替换节点名称 [英] Replace Node Name

问题描述

是否可以替换节点名称?喜欢:

Is it possible to replace a nodes name? Like:

HTML:

<strong id="element">Text</strong>

Javascript:

Javascript:

var element = document.getElementById("element");
    element.nodeName = "b";

据我所知这是行不通的，如果不可能以这种方式实现，那怎么办?

As I see it's not working, if it's not possible in this way, then how can it be done?

为什么我需要它:

我正在构建一个文本编辑器，IE 在 execCommand() 函数中使用 strong 而不是 b，我想改变它，我试图从头开始构建 execCommand("bold") 但有很多即使在 IE 8 和 9 之间也存在问题和差异.所以现在我决定更改它的节点名称，这真的很容易，但不起作用.. :(

I'm building a Text Editor, and IE uses strong instead of b in the execCommand() function and I would like to change that, I tried to build the execCommand("bold") from scratch but there is a lots of problem and differences even between IE 8 and 9. So now I decided to change it's node name, it would be really easy, but doesn't works.. :(

注意:我只需要它在 Internet Explorer 中工作.

Note: I need this to work only in Internet Explorer.

谢谢

推荐答案

不需要，但您可以轻松替换节点:

No, but you can replace the node easily:

var oldNode = document.getElementById('element'),
    newNode = document.createElement('b'),
    node,
    nextNode;

node = oldNode.firstChild;
while (node) {
    nextNode = node.nextSibling;
    newNode.appendChild(node);
    node = nextNode;
}

newNode.className = oldNode.className;
// Do attributes too if you need to
newNode.id = oldNode.id; // (Not invalid, they're not both in the tree at the same time)
oldNode.parentNode.replaceChild(newNode, oldNode);

实例

非常感谢 Haochi 指出replaceChild，我已经做到了:

Many thanks to Haochi for pointing out replaceChild, I had done this:

oldNode.parentNode.insertBefore(newNode, oldNode);
oldNode.parentNode.removeChild(oldNode);

现场示例 ...但 replaceChild 更简洁.

Live example ...but replaceChild is cleaner.
