i have form 1 hidden value want submit without refreshing page or response message server. how can implement in ajax? form. have form in same page.

<form id = "id_form" action = "validate.php" method = "post">  <input type = "hidden" name = "task_id" id = "task_id" value = <?php echo $_get['task_id'];?>> </form>

similar zafar's answer using jquery

actually 1 of examples on jquery site https://api.jquery.com/jquery.post/

$(document).ready(function() {     $.post("validate.php", $("#id_form").serialize()); });

you can .done(), .fail(), , .always() if want response said did not want.

in pure javascript

body.onload = function() {     var xmlhttp = new xmlhttprequest();     xmlhttp.open("post","validate.php",true);     xmlhttp.setrequestheader("content-type","application/x-www-form-urlencoded");     xmlhttp.send("task_id=" + document.getelementbyid("task_id").value); };
