Try This Example.
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$( document ).ready(function() {
$("button").click(function() {
alert(this.id); // or alert($(this).attr('id'));
});
});
</script>
</head>
<body>
<button id="some_id1"></button>
<button id="id2"></button>
<button id="id3"></button>
<button id="id4"></button>
<button id="id5"></button>
</body>

$('body').append("<button data-value='val' class='my_remark_btn'>val</button>") $(document).on('click', '.my_remark_btn', function() { alert($(this).attr('data-value')) })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
- Button has no
value. - Use data attribute like
data-value. - Get it like
$(this).attr('data-value')using this context for clicked button. - Use event delegation for dynamically added elements.

Have a try of this
jQuery
$('.my_remark_btn').click(function(){ // when a button is clicked
var value = $(this).value; // get the value of that specific button
alert(value); // alert the value to the page (to make sure it is correct)
remark_aftr_click(value); // run function, with value as a parameter
});
function remark_aftr_click(val){
$.ajax({
url: "my_remark_act.php",
cache: true,
type: "POST",
data: {go: val}, // post data to Ajax with CORRECT value
success: function(data){
alert(data); // alert returned data
}
});
}
Why your code was not working :
When you were retrieving the value of .my_remark_btn before, you were only ever getting the value of the first element with that specific class.
How you can get it to work :
Instead, you need to pass the value as a parameter within your function (while using this as a selector to get the value of that specific button).
Hope this helps :-)

You can use JQuery. try the below code.
// this will fire for all button having class '.my_remark_btn'
$('.my_remark_btn').click(function(){
// using $(this) you will get the current element
var value = $(this).val();
console.log(value);
});
In you code you are accessing value by var k = $(".my_remark_btn").val(); , This will only return value of the first button with class my_remark_btn .

You need $(this).attr("value") like below:-
<script type="text/javascript">
$('.my_remark_btn').click(function(){
var k = $(this).attr("value");
$.ajax({url: "my_remark_act.php",
cache: true,
type: "POST",
data: {go:k},
success: function(data_remark_mi){
alert(data_remark_mi);
}
});
});
</script>
Example:-
$('.my_remark_btn').click(function(){ var k = $(this).attr("value"); alert(k); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button value ="1" class="my_remark_btn">1</button><br> <button value ="2" class="my_remark_btn">2</button>
