如何在C＃背后的代码中获取hreflang值

Question

<link rel="alternate" hreflang="zh-cn" /><br />

How to get hreflang value in code behind c#. I tried many ways but still not working.

Answer 1

You can try this way :

<link rel="alternate" id="hrid" hreflang="zh-cn" />

    var v = document.getElementById("hrid").hreflang;

Answer 2

You need to make the <link /> tag a server-side control by adding ID and runat attributes:

<link id="AlternateLink" runat="server" rel="alternate" hreflang="zh-cn" />

You can retrieve the value of the hreflang attribute from your code-behind by using this code:

string hrefLangAttr = AlternateLink.Attributes["hreflang"].ToString();
