How to get div value dynamically with jquery and php - php

Question

I have to get the value of something when I press an accordion div. This div=" accordion" has this structure:
<div class="accordion">
<? if ($_SESSION[SITE]['user']['id'] == $message['yp_from']) { ?> <div class="row"><span class="bold">From: </span> <span>Me</span>
<span class="grey9"> <?= $this->tools_lib->date_format($message['yp_time']); ?></span>
<? } else { if ($message['yp_state_from'] == 0) {?>
<div class="row"><span class="bold">From: </span><span><?= $this->tools_lib->name_separate($message['yp_name']) ?></span>
<div id="idMens<?= $message['id'] ?>" style="display:none;" class="showNew"><?= $message['id'] ?></div></span>
<h5 id="new"> New </h5>
<?} else { ?>
<div class="row"><span class="bold">From: </span><span><?= $this->tools_lib->name_separate($mensaje['yp_name']) ?></span>
<? }
} ?>
</div>
<p><?= $message['yp_message'] ?><p>
</div>
I want to get · $mensaje['id'] · value from the "div id="idMens"". I was trying to do it with jquery. but I have problems to get the correct value, it always take the first item value, I mean the last dinamically typed.
Im trying to use this jquery code. but I think is not well formed code..
<script>
$(document).ready(function(){
$('.accordion').find('div').click(function(){
$(this).next().slideToggle();
$('.showNew').on('click', function() {
var idm =this.id;
});
var form_data = {
to: $('#',idm).html()
}
$.ajax({
url: _baseurl+""+_lang+"/messages/updateState/", // ruta del controlador y accion
type: 'POST',
data: form_data,
success: function(data){
$('#new').hide();
}
});
}).next().hide();
});
</script>
Thank you!

Finally I did it. I'm fool... it was so easy. I was in the wrong way.
I did it creating other function:
function changeState(id){
var form_data = {
to: id
}
$.ajax({
url: _baseurl+""+_lang+"/messages/updateState/", // ruta del controlador y accion
type: 'POST',
data: form_data,
success: function(data){
$('#new').hide();
}
});
}
And calling it in the first div. with onclick. I pass the dinamic id as a parameter and therefore I can use it well.
Thank you
