来自< A>的POST标签 [英] POST from an <A> tag

问题描述

是否可以从< a> 标签执行POST？我知道锚标签通常只是为GETs，我知道我可以使用JavaScript来做到这一点（如 JavaScript post request like a form submit ），但对我来说似乎有点混乱。有没有办法做到这一点直HTML？

解决方案

有没有办法 POST <



从这个DTD片段可以看出（ a a a href =http://www.w3.org/TR/html401/struct/links.html#adef-href =noreferrer> HTML 4.01规范）：



 <！ELEMENT A  -   - （％inline;）*  - （A） -  anchor  - > 
<！ATTLIST A 
％attrs; - ％coreattrs，％i18n，％events  -  
 charset％Charset; #IMPLIED  - 链接资源的字符编码 -  
 type％ContentType; #IMPLIED  - 咨询内容类型 -  
名称CDATA #IMPLIED  - 指定链接结束 -  
 href％URI; #IMPLIED  - 链接资源的URI  -  
 hreflang％LanguageCode; #IMPLIED  - 语言代码 -  
 rel％LinkTypes; #IMPLIED  - 前向链接类型 -  
 rev％LinkTypes; #IMPLIED  - 反向链接类型 -  
 accesskey％字符; #IMPLIED  - 辅助键字符 -  
形状％形状; rect  - 用于客户端图像映射 -  
 coords％Coords; #IMPLIED  - 用于客户端图像映射 -  
 tabindex NUMBER #IMPLIED  - 按切换顺序的位置 -  
 onfocus％Script; #IMPLIED  - 获得焦点的元素 -  
 onblur％Script; #IMPLIED  - 元素失去焦点 -  
> 
  

没有属性控制是否使用 POST 或> 元素。

如果您想滥用语义，您必须来编写脚本。

Is it possible to do a POST from just an <a> tag? I know anchor tags are usually just for GETs, and I know I can use javascript to do this (like in JavaScript post request like a form submit) but to me that seems a little messy. Is there a way to do this with straight HTML?

解决方案

There is no way to POST an a element using only HTML.

As can be seen from this DTD fragment (HTML 4.01 spec):

<!ELEMENT A - - (%inline;)* -(A)       -- anchor -->
<!ATTLIST A
  %attrs;                              -- %coreattrs, %i18n, %events --
  charset     %Charset;      #IMPLIED  -- char encoding of linked resource --
  type        %ContentType;  #IMPLIED  -- advisory content type --
  name        CDATA          #IMPLIED  -- named link end --
  href        %URI;          #IMPLIED  -- URI for linked resource --
  hreflang    %LanguageCode; #IMPLIED  -- language code --
  rel         %LinkTypes;    #IMPLIED  -- forward link types --
  rev         %LinkTypes;    #IMPLIED  -- reverse link types --
  accesskey   %Character;    #IMPLIED  -- accessibility key character --
  shape       %Shape;        rect      -- for use with client-side image maps --
  coords      %Coords;       #IMPLIED  -- for use with client-side image maps --
  tabindex    NUMBER         #IMPLIED  -- position in tabbing order --
  onfocus     %Script;       #IMPLIED  -- the element got the focus --
  onblur      %Script;       #IMPLIED  -- the element lost the focus --
  >

There is no attribute that controls whether to use POST or GET with an a element.

You have to script it, if you want to abuse the semantics.
