How can I submit a POST form using the <a href="..."> tag?

Question

How can I submit a POST form to showMessage.jsp using just the <a href="..."> tag?

<form action="showMessage.jsp" method="post">     <a href="showMessage.jsp"><%=n%></a>     <input type="hidden" name="mess" value=<%=n%>/> </form> 

Answer 1

No JavaScript needed if you use a button instead:

<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:

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

Answer 2

You need to use javascript for this.

<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>
