I want to send the id of a button when it is clicked using HTTP Post method, I've written the following code. But the server is not receiving the id of the button when I press the button. could anyone please guide me, what's going wrong here? Thanks in Advance.
<HTML>
<head>
<script>
function fun1(element) {
var xhttp = new XMLHttpRequest();
xhttp.open("POST", "/prc", true);
xhttp.send(element.id);
//alert("ID":element.id);
}
</script>
</head>
<body>
<button type="button" onclick="fun1(this)" id="img1">IMAGE</button>
</body>
</html>
