Get the data that is being loaded by jquery in PHP CodeIgniter - php

Question

I have this dropdown menu using form_helper in CodeIgniter:
<?php if($materialType): ?>
<?php
$material_options = array();
foreach($materialType as $rows){
$material_options[$rows->id] = $rows->category;
}
echo form_dropdown('materialType',$material_options,'','id="materialType"');
?>
<?php endif; ?>
<div id="materials"></div>
The code above is inside a <form> tag and I have this script:
<script type="text/javascript">
var base_url = "<?php echo base_url(); ?>";
</script>
<script>
$(document).ready(function(){
$(document).on('change','#materialType',function(){
loadthis();
});
function loadthis(){
var ID = $('#materialType').val();
var dataString = 'id='+ ID ;
$.ajax({
type: "POST",
url: base_url + "index.php/admin/get_material",
data: dataString,
cache: false,
success: function(data)
{
$('#materials').html(data);
}
});
}
loadthis();
});
</script>
And here is the code that is being loaded:
<div id="materials">
<?php if($materials): ?>
<table>
<th>Name</th>
<th>Description</th>
<?php foreach($materials as $row): ?>
<tr>
<td><?php echo $row->mname; ?></td>
<td><?php echo $row->mdesc; ?></td>
<td>
<button class="try" value="<?php echo $row->id; ?>">Add</button>
</td>
</tr>
<?php endforeach; ?>
</table>
<?php else: ?>
<div class="alert alert-error" style="width:300px;">No Resource Available!</div>
<?php endif; ?>
$(document).on('click','.try',function(){
alert($(this).val());
return false;
});
And what i want is if the Add button is being click I can get the ID,mname and store it until the form is submitted.
How can I do that using .data() in jquery? or Any ideas on how to store it until the form is being submit.

Answer 1

I didn't thoroughly look at your code, but I noticed when you print your table rows in a loop you have the id="try" assigned to all of the rows. the html id-attribute is a unique identifier so the JS that is alerting the value will only return the value of the first id it will find (at least that's what i think). Try to use a class instread of an id and then use this in your js.
$(document).on('click','.try',function(){
alert($(this).val());
return false;
});
