here is my link
<a data-toggle="tooltip" data-placement="top" title="Edit" class="btn btn-info" href="close_case_edit.php?pw_case_close_id= <?php $row['pw_case_close_id']; ?>">
On next page I fetch value using php
$pw_case_close_id = $_GET['pw_case_close_id'];
but i want fetch this value using ajax as i want update this page using API
You can use .split() along with .attr()
A sample working example:-
$(document).ready(function(){
var value = $('a.btn-info').attr('href').split('=')[1];
console.log(value);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a data-toggle="tooltip" data-placement="top" title="Edit" class="btn btn-info" href="close_case_edit.php?pw_case_close_id=2"></div>
