You can pass value to server using ajax calls. See the following code. Here We use a confirm box to get user confirmation.
function deleteEmployee(empId){
var confirm=confirm("Do you want to delete?");
if (confirm)
{
var url = "path/to/delete.php";
var data = "emp_id="+empId;
$.ajax({
type: "POST",
url: "otherfile.php",
data: data ,
success: function(){
alert("Employee deleted successfully.");
}
});
}
}
In delete.php you can take the employee id by using $_POST['emp_id']
