I have a list of employees generated dynamically from database, and each employee has got an id, now I want to open a div box on each click with respect to the id's and display their id's in that box. I am not able to access that div with respect to the id selected.
include 'connect.php';
$ert=mysql_query("Select * from login_session where bit='0' and date='$date'") or die(mysql_error());
while($we=mysql_fetch_array($ert)){
$employee_id=$we['employee_id'];
?>
<li> <a href="#" data-employee="<?php echo $we['employee_id']; ?>" class="addClass"><?php echo $we['name'];?></a></li>
<div class="popup-box chat-popup" id="employee_<?php echo $employee_id; ?>">

<script>
$(function(){
$(".addClass").click(function () {
var var1=$(this).data('employee');
$('#employee_'+var1).addClass('popup-box-on');
});
$(".removeClass").click(function () {
var var1=$(this).data('employee');
$('#employee_'+var1).removeClass('popup-box-on');
});
})
</script>
Firstly , inside the anchor tag <a> with class .addClass , you are using $we['employee_id'] and then for it's respective box you are using $employee_id which is null and it results to an undefined variable error.
You should give the trigger and target selectors a unqiue identifiers , such as for .addClass you can use data attributes for appending the data to target something. look below:
<a href="#" data-employee="<?php echo $we['employee_id']; ?>" class="addClass"><?php echo $we['name'];?></a>
and then for respective box id you can assign a unique id to it something like:
<div class="popup-box chat-popup" id="employee_<?php echo $employee_id; ?>">
and at the end inside javascript / jquery , you can trigger them with the data attribute value and by placing the unique identifier we have created for target div. let say .addClass's data attribute contains 34, which is a employee id , and .popup-box will have id="employee_34" as we need to identify them with something unique and not only numbers.
$(function(){
$(".addClass").click(function () {
var var1=$(this).data('employee');
$('#employee_'+var1).addClass('popup-box-on');
});
});
at the end you php and html code should look like this:
include 'connect.php';
$ert=mysql_query("Select * from login_session where bit='0' and date='$date'") or die(mysql_error());
while($we=mysql_fetch_array($ert)){
?>
<li> <a href="#" data-employee="<?php echo $we['employee_id']; ?>" class="addClass"><?php echo $we['name'];?></a></li>
<div class="popup-box chat-popup" id="employee_<?php echo $employee_id; ?>">

<?php } ?>
and your javascript code like below:
$(function(){
$(".addClass").click(function () {
var var1=$(this).data('employee');
$('#employee_'+var1).addClass('popup-box-on');
});
});
and do in this way same for removing the respective box for employee div.
Note
As the popup-box div's are multiple and are already inside the dom , you should not use id selector for remove trigger , as it will target only first div and not others , use an class for removing the div as well such as removeBox
Update for remove
For removing the div, don't use id for removing the div , change your remove button to the following:
<button data-widget="remove" data-employee="<?php echo $we['employee_id']; ?>" class="chat-header-button removeClass pull-right" type="button"><i class="glyphicon glyphicon-off "></i></button>
and use the below jquery code for removing the div
$(function(){
$(".removeClass").click(function () {
var var1=$(this).data('employee');
$('#employee_'+var1).removeClass('popup-box-on');
});
});
