问题
Newbie here. I did an ajax to count the users and display it on my badge, however, whenever I'm clicking on 1 button (Modal with table), it is displaying on all badges. For example. I have 4 users in my first row modal table. The #4 count is displayed to all of my badges. Which is something that is weird. My target is to display the count in my badge dynamically. I have provided a video and images below for better explanation.
https://streamable.com/z6dqgi << This is the output of what I made. (Look at the badge count behaviour)
This is what I aim/target for.

As you have use .navbar-badge this will target all elements which has that class that's the reason its changing all span tags. Instead , as you are already getting data-id of button you can use this to target only required span using $("span[data-id=" + view_id + "]").text("sometext") .
Demo code :
$(document).ready(function() {
$(".allTable").on("click", function() {
var view_id = $(this).data('id')
/*$.ajax({
//somecodes of ajx ..
*/
// $("span[data-id="+view_id+"]").text(Object.keys(item).length);
$("span[data-id=" + view_id + "]").text(10);
// other codes ..
/* }
});*/
})
