问题描述
问 题
<a name='xxx'>与<a href='xxx'>有什么区别吗？
<!DOCTYPE html>
<html>
<body>
<a name="html">HTML Tutorial</a><br>
<a name="css">CSS Tutorial</a><br>
<a name="xml">XML Tutorial</a>
<p>innerHTML of the first anchor:
<script>
document.write(document.anchors[0].innerHTML);
</script>
</p>
</body>
</html>解决方案
官方说明：
For reasons of backwards compatibility, the returned set of anchors only contains those anchors created with the name attribute, not those created with the id attribute.
所以document.anchors只会返回有name属性的<a>节点。
另外，这种方式已经废弃，最好不要使用
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
