getting the value of a hidden input - php

Question

I have this code:
<div id = "askpost" class="row">
<input type="hidden" name="askid" id="askid" value="<?php echo $askpostid ?>">
</div>
and i want to get the id of the hidden input but when tried using this:
<script>
$(document).ready(function() {
$('input[name="iaskcomment"]').on('keyup', function(e){
e.preventDefault();
var comment = $(this).val();
var ask_id = $(this).siblings('.askid').val();
alert(ask_id); <----undefined
});
});
</script>
i even used this code :
var sid = $(this).closest("div#askpost").find("input[type='hidden']").val();
but also i get "undefined". what i wanted to do is to get the id of $askpostid

Answer 1

direct use $("#askid").val(). No need to use anything like siblings()
Example:-
$(document).ready(function() {
$('input[name="iaskcomment"]').on('keyup', function(e){
e.preventDefault();
var comment = $(this).val();
var ask_id = $('#askid').val();
alert(ask_id);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id = "askpost" class="row">
<input name = "iaskcomment"><br>
<input type="hidden" name="askid" id="askid" value="2">
</div>
Note:- Your code doesn't have any input with name iaskcomment. I have added in my example to just show you how it will work.So check at your end.
