validation - HTML 验证错误 : Bad value tooltip for attribute rel on element a: Keyword tooltip is not registered

Question

我应该关注以下 HTML 验证错误吗？

        …rel="tooltip" data-placement="bottom" data-original-title="Permalink"></a></li>
        Syntax of link type valid for <a> and <area>:
        A whitespace-separated list of link types listed as allowed on <a> and <area> in the HTML specification or listed as an allowed on <a> and <area> on the Microformats wiki without duplicate keywords in the list. You can register link types on the Microformats wiki yourself.

Answer 1

“rel”值工具提示不是 html 5 中的有效属性。

替换 rel属性与 data-rel您的代码中的属性(绝对有效)。

例如:
$("a[rel]").tooltip();至 $("a[data-rel]").tooltip();
