Need alternative POST method for window.open, showmodeldialog and startDownload

Question

In Javascript currently these functions are sending GET request window.open, showmodeldialog and startDownload.

What is the alternative method to send these request as POST.

Answer 1

You can try something like this

<form id="myForm" method="POST" action="..." target="myWindow">
   <!-- Whatever you need -->
</form>

And in your javascript:

<script>
  window.open("about:blank", "myWindow", /*additional params...*/);
  document.getElementById('myForm').submit();
</script>
