Making href (anchor tag) request POST instead of G

问题:

This question already has an answer here:

  • Make a link use POST instead of GET 9 answers
<a href="employee.action" id="employeeLink">Employee1</a>

when i click the Employee1 link, GET request goes to server. I want to make it POST instead of GET request. Is there a way i can change default GET behaviour of href?

Note:- I know it can be done where we can call javascript function on hyperlink click , then create form and submit it. But i am looking where we can mention some attribute in anchor tag to make POST request instead of GET request?

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.onload=function() {
   document.getElementById("employeeLink").onclick=function() {
     document.getElementById("myForm").submit();
     return false; // cancel the actual link
   }
 }

Without a form we need to make one

 window.onload=function() {
   document.getElementById("employeeLink").onclick=function() {
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
     return false; // cancel the actual link
   }
 }

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">
