错误验证W3C HTML5 img noscript facebook.com [英] Errors validation W3C HTML5 img noscript facebook.com
问题描述
我正在尝试将我的页面验证为HTML 5（W3c）。我有以下错误：这里不允许使用img元素（作为noscript元素的子元素）。当head的子元素时，noscript元素必须只包含以下子元素：link，style和meta。
I am trying to validate my page as HTML 5 (W3c). And I have the following error: The "img" element is not allowed here (as a child of the "noscript" element). The "noscript" element, when a child of "head", must contain only the following child elements: "link", "style", and "meta".
现场 https://developers.facebook.com/docs / ads-for-websites / conversion-pixel-code-migration 推荐我的代码：
将升级的代码段复制并粘贴到< head> ;以及< / head> ;在您要跟踪转化的网站的HTML代码中。例如，要跟踪注册，请将代码放在您的网站上'注册完成'网页。
On site https://developers.facebook.com/docs/ads-for-websites/conversion-pixel-code-migration recommendation for my code:
"Copy and paste the upgraded code snippet between <head>; and </head>; in the HTML code of your website where you want to track conversions. For example, to track registrations, place the code on your 'registration completed' web page."
请参阅源代码：
<head>
<script type="text/javascript">
var fb_param = {};
fb_param.pixel_id = '1234567890';
fb_param.value = '10.00';
fb_param.currency = 'USD';
(function(){
var fpw = document.createElement('script');
fpw.async = true;
fpw.src = '//connect.facebook.net/en_US/fp.js';
var ref = document.getElementsByTagName('script')[0];
ref.parentNode.insertBefore(fpw, ref);
})();
</script>
<noscript><img height="1" width="1" alt="" style="display:none" src="https://www.facebook.com/offsite_event.php?id=1234567890&value=10.00¤cy=USD" /></noscript>
</head>
是否可以修改此代码并通过验证（在头部）？
Is it possible to modify this code and pass validation (in head section)?
推荐答案
W3C的HTML5规范定义了头中的html5-20141028 / scripting-1.html #the-noscript-elementrel =nofollow> noscript 元素 这样的元素：
W3C’s HTML5 specification defines the content model of a noscript element in the head element like this:
[...]任何顺序，零个或多个
链接元素，零个或多个样式元素，零个或多个元元素。
[…] in any order, zero or more
linkelements, zero or morestyleelements, and zero or moremetaelements.
如您所见，除了 link / <$ c之外，它不能包含任何其他内容$ c> style / meta 元素。所以不，在<$ c里面的 noscript 元素内修改任何东西都不可能允许 img $ c> head 元素。
As you can see, it cannot contain anything else than link/style/meta elements. So no, it’s not possible to modify anything to allow an img inside of a noscript element inside of the head element.
但是你可以在 img 里面code> noscript 如果你将 noscript 元素放在正文中，在这种情况下，内容模型是：
But you can have an img inside of noscript if you place the noscript element in the body, as the content model is in that case:
透明，但必须没有
noscript元素后代。
透明表示它与其父元素具有相同的内容模型。因此，例如，如果 noscript 位于 div 内，它可能包含的任何内容div 可能包含（除了另一个 noscript ）。
Transparent means that it has the same content model as its parent element. So for example, if the noscript is inside a div, it may contain anything that a div may contain (except of another noscript).
