我们是否需要注册自定义标签？ [英] Do we need to register Custom Tag?

问题描述

我一直在阅读有关HTML5自定义元素的这篇文章。

它说我需要在使用它之前注册元素的名称，例如：

  var XFoo = document.registerElement（'x-foo'）; 
 document.body.appendChild（new XFoo（））; 
  

然后我可以开始正常使用它：

 < X-FOO> ...< / X-FOO> 
  

但我只是在未经Chrome，Firefox和IE11注册的情况下尝试使用它。所有似乎都呈现得很好，即使CSS选择器 x-foo 也可以。

我猜我们不再需要注册，因为大多数浏览器都支持它？

谢谢

解决方案

简短回答：否。

作为一种好习惯，总是定义一些不是官方的东西。仅仅因为它适用于所有/大多数浏览器并不能使其正确。这与使用尚未定义的变量相似，然后编译器自动定义它。当然，它可以工作，但这并不能说明问题。

I have been reading this article about HTML5 Custom Element.

It said I need to register the element's name before using it like:

var XFoo = document.registerElement('x-foo');
document.body.appendChild(new XFoo());

Then I can start using it normally:

<x-foo>...</x-foo>

But I just tried using it without registering in Chrome, Firefox, and IE11. All seems to render just fine, even CSS selector for x-foo also works.

I'm guessing that we no longer need to register since most browsers have supported it?

Thanks

解决方案

Short answer: No.

As a good practice, always define things that are not official. Just because it works by all/most browsers does not make it correct. That would be similar to using a variable which is yet to be defined, and then the compiler automatically defining it. Sure, it works, but that does not make it right
