No JavaScript needed if you use a button instead:

如果您使用按钮，则不需要JavaScript:

<form action="your_url" method="post">
  <button type="submit" name="your_name" value="your_value" class="btn-link">Go</button>
</form>

You can style a button to look like a link, for example:

你可以将一个按钮设计成一个链接，例如:

.btn-link{
  border:none;
  outline:none;
  background:none;
  cursor:pointer;
  color:#0000EE;
  padding:0;
  text-decoration:underline;
  font-family:inherit;
  font-size:inherit;
}

You have to use Javascript submit function on your form object. Take a look in other functions.

必须在表单对象上使用Javascript提交函数。看看其他函数。

<form action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

You need to use javascript for this.

为此需要使用javascript。

<form id="form1" action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="document.getElementById('form1').submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

In case you use MVC to accomplish it - you will have to do something like this

如果您使用MVC来完成它——您将不得不做这样的事情

 <form action="/ControllerName/ActionName" method="post">
        <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
        <input type="hidden" name="mess" value=<%=n%>/>
    </form>

I just went through some examples here and did not see the MVC one figured it won't hurt to post it.

我只是在这里浏览了一些例子，并没有看到MVC，我认为发布它不会有什么坏处。

Then on your Action in the Controller I would just put <HTTPPost> On the top of it. I believe if you don't have <HTTPGET> on the top of it it would still work but explicitly putting it there feels a bit safer.

然后，在控制器中的操作上，我只需将放在它的顶部。我相信如果上面没有，它仍然可以工作，但是显式地把它放在那里会更安全一些。

There really seems no way for fooling the <a href= .. into a POST method. However, given that you have access to CSS of a page, this can be substituted by using a form instead.

似乎真的没有办法欺骗

Unfortunately, the obvious way of just styling the button in CSS as an anchor tag, is not cross-browser compatible, since different browsers treat <button value= ... differently.

不幸的是，将CSS中的按钮作为锚标记的明显方式，不是跨浏览器兼容的，因为不同的浏览器处理

Incorrect:

<form action='actbusy.php' method='post'>
  <button type='submit' name='parameter' value='One'>Two</button>
</form>

The above example will be showing 'Two' and transmit 'parameter:One' in FireFox, while it will show 'One' and transmit also 'parameter:One' in IE8.

上面的示例将在FireFox中显示“Two”并传输“parameter:One”，而在IE8中，它将显示“One”并传输“parameter:One”。

The way around is to use hidden input field(s) for delivering data and the button just for submitting it.

方法是使用隐藏的输入字段(s)来传递数据，并使用按钮来提交数据。

<form action='actbusy.php' method='post'>
   <input class=hidden name='parameter' value='blaah'>
   <button type='submit' name='delete' value='Delete'>Delete</button>
</form>

Note, that this method has a side effect that besides 'parameter:blaah' it will also deliver 'delete:Delete' as surplus parameters in POST.

注意，这个方法有一个附加的效果，除了“参数:blaah”，它还会发送“delete: delete”作为POST中的剩余参数。

You want to keep for a button the value attribute and button label between tags both the same ('Delete' on this case), since (as stated above) some browsers will display one and some display another as a button label.

您希望为按钮保留标记之间的值属性和按钮标签(在本例中是“Delete”)，因为(如上所述)一些浏览器将显示一个，另一些浏览器将显示另一个作为按钮标签。
