Retrieving value from inside checkbox column

Retrieving value from inside checkbox column

Hello,
I have a datatable that has multiple column checkboxes. Each column that has a checkbox has an ID that is being rendered via a query from my database. Up until recently I had only implemented datatables that had only one column checkbox and used the row selection extension that works great. Now, I'm implementing a datatable that will have multiple column checkboxes that will be selected individually.
I'm attempting to get the value from inside the columns that have a checkbox checked. So far, I have not been able to get any values using the onClick jquery with an alert box for testing. Code:

Datatable initialization:

<script type="text/javascript">

$(document).ready(function(){
    $.fn.dataTable.ext.errMode = 'none';
// Setup Data Table
    $('#studentAtt').DataTable(
        {
            
            'initComplete': function(setings,json){
                $('div.overlay').remove();
            },
            'lengthChange':false,
                'processing': true,
            'orderClasses': false,
            'scrollY': 300,
            'scroller':false,
            'paging':true,
            'pageLength': 50,
            'scrollCollapse':false,
                        'columnDefs': [
                 {
                    'targets': [0,10,11],
                    'checkboxes': {
                       'selectRow': false
                    }
                 },
                {
                     'targets':[1],
                     'visible':false
                }
              ],
              'select': {
                 'style': 'multi'
              },
              'order': []

        });

                $('#studentAtt tbody').on('click','tr td:nth-child(1) input', function () {
            var currentRow1=$(this).closest('tr');
        var col1=currentRow1.find('td:eq(0)').text();
        alert('Column1 CHCKB Value: ' + col1 );
    } );
});
</script>

HTML datatable, being loaded by database query call:

<cfoutput>
<table id="studentAtt" class="display" cellspacing="0" style="width:100%;">
        <thead>
            <tr>
                 <th style="width:10px;"></th>
                <th style="font-size:10px; width:55px; ">State ID</th>
                <th style="font-size:10px; width:55px; ">Local ID</th>
                <th style="font-size:10px;">Last</th>
                <th style="font-size:10px;">First</th>
                <th style="font-size:10px;">Middle</th>
                <th style="font-size:10px;">Campus</th>
                <th style="font-size:10px;">Grade</th>
                <th style="font-size:10px;">Status</th>
                <th style="font-size:10px;">Pre. Alg. Enrolled</th>
                <th style="font-size:10px;">Pre. Alg. Completed</th>
            </tr>
        </thead>
        <tbody>
<cfloop query="getStudents">
<tr> 
<td width="10">>#GUID#</td>
<td style="font-size:10px; ">#TEXAS_UNIQUE_ID#</td> 
<td style="font-size:10px; ">#LOCAL_ID#</td> 
<td style="font-size:10px;">#STU_LAST#</td>
<td style="font-size:10px;">#STU_FIRST#</td>  
<td style="font-size:10px;">#STU_MIDDLE#</td> 
<td style="font-size:10px;">#CAMPUS#</td> 
<td style="font-size:10px;">#GRADE#</td> 
<td style="font-size:10px;">#STATUS#</td> 
<td >#GUID#</td>
<td>#GUID#</td>


</tr> 
</cfloop>
</tbody>
<tfoot></tfoot>
</table>
</cfoutput>

The alert box doesn't display anything, however If I change the column to the second column, TEXAS_UNIQUE_ID, I get the value in this colunm:

                $('#studentAtt tbody').on('click','tr td:nth-child(1) input', function () {
            var currentRow1=$(this).closest('tr');
        var col1=currentRow1.find('td:eq(1)').text();
        alert('Column1 CHCKB Value: ' + col1 );
    } );

I have also tested, changing third line above to:
var col1=currentRow1.find('td:eq(0)').html();

but that only displays on the alert on click event:
"Column1 CHCKB Value: <input type="checkbox" class="dt-checkboxes">"

I can't seem to get the value below the checkbox assigned to the column. Any insight will be greatly appreciated.

Thanks,

Daniel

    We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

    Cheers,

    Colin
