Cannot read property '_aData' of undefined(…) - Datatables - javascript

I'm trying to read data() from a cell in a datatable which has a button inside it, but I'm getting en error.
This is my Datatable definition:
$("#example").DataTable({
destroy: true,
"columnDefs": [{
orderable: false,
targets: 0
}],
"columns": [
{
"data": "slno",
"fnCreatedCell": function (nTd, sData, oData, iRow, iCol) {
$(nTd).html('' + oData.slno + '');
},
},
{ "data": "status_message" },
{ "data": "crm_services_id" },
{ "data": "subject_id" },
{ "data": "severity_id" },
{"data": "user_id" },
{ "data": "status_id" },
{
"data": "caller_number",
"fnCreatedCell": function (nTd, sData, oData, iRow, iCol) {
$(nTd).html('<button class="btn btn-primary" id= "' + oData.subjectID + '">Call Customer</button>');
},
}
],
select: {
style: 'os',
selector: 'td:first-child'
},
"data": response,
"sDom": '<"top">tip'
});
And here is where I'm trying to fetch the data:
var table = $("#example").DataTable();
$('#example tbody').on('click', 'button', function () {
var subjectID = $(this).attr('id');
var thisData = table.row($(this).parents('tr')).data();
var userID = thisData[7];
sendCallRequest(subjectID, userID);
});
Here is the error I'm getting:
Cannot read property '_aData' of undefined(…)
Any suggestions please?

Try unbinding the event for your buttons before you re-assign them:
var table = $("#example").DataTable();
$('#example tbody').off('click');
$('#example tbody').on('click', 'button', function () {
var subjectID = $(this).attr('id');
var thisData = table.row($(this).parents('tr')).data();
var userID = thisData[7];
sendCallRequest(subjectID, userID);
});
Why am I suggesting this: I have a pretty similar problem, where DataTables is not able to call the rowReorder event. I also create my table via AJAX / dynamically (which you seem to do aswell), so obviously my event listener (in my case for table.on('row-reorder')) was bound multiple times. After first removing the event listener and readding it, finally I got this to work.

How do I Link a TD in dataTable?

I have a function like this. How do I hyperlink specific columns? Lets say I want to have the Download FIle render like this Download File And where uploadFile/file is the path of my download link. When I try to run this function, it not fill the table. Could you guys help me out?
function tabela() {
var table = $("#example1").DataTable({
"ajax": "pages/forms/request.php",
"columns":
[
{ "data": "ID" },
{ "data": "SERIAL_NUMBER" },
{ "data": "AUDITOR" },

$(nTd).html("<a href='uploadFiles/" + oData.ARQUIVO + "'>Download File</a>");
},
{ "data": "DATA" },
]
}
);
}
tabela();

Trying to access dataTable variable outside ajax is giving undefined

I have a jquery autocomplete that once a value is selected it loads a datatable with checkbox from an ajax call. Then while submitting the form I need to access the datatable variable to iterate each row to get the selected ones, but the datatable variable appears as undefined.
I'm doing the same as in this example, only difference is the data is coming from an Ajax request.
Can you please help me understand why is that happening?
$(document).ready(function() {
var campId;
var t_OmnitureCode;
// Campaign input autocomplete
$("#campaign").autocomplete({
source: function(request, response) {
$.ajax({
url: "promotion",
type: "GET",
data: {
term: request.term,
action: "searchCampaign"
},
dataType: "json",
success: function(data) {
if (!data.length) {
var result = [{
label: "no match found",
value: "-1"
}];
response(result);
} else {
response($.map(data, function(item) {
return {
label: item.name,
value: item.campaignId
}
}));
}
}
});
},
select: function(event, ui) {
event.preventDefault();
campId = ui.item.value;
if (campId != "-1") {
this.value = ui.item.label;
// This will apply datatables getting the content from an Ajax call
t_OmnitureCode = applyDataTableOmnitureCode(campId);
}
},
focus: function(event, ui) {
event.preventDefault();
this.value = ui.item.label;
}
});
// Handling form submission
$("#frm_promotion").on("submit", function(e) {
var form = this;
// Variable for datatable "t_OmnitureCode" is undefined below
var rows_selected = t_OmnitureCode.column(0).checkboxes.selected();
EDIT:
Just realized that even while assigning the variable (t_OmnitureCode = applyDataTableOmnitureCode(campId);) it is undefined, not sure why.
Here is the applyDataTableOmnitureCode code:
function applyDataTableOmnitureCode(campId) {
$("#tbl_omnitureCode").DataTable({
destroy: true,
scrollX: true,
fixedColumns: {
leftColumns: 1
},
"ajax": {
"url": "promotion",
"type": "GET",
"data": {
action: "searchOmnitureCodesByCampaignId",
campaignId: campId
},
"dataSrc": ""
},
"columns": [
{ "data": "key" },
{ "data": "omnitureCode" },
{ "data": "urlAppName" },
{ "data": "language" },
{ "data": "channel" },
{ "data": "createDateTime", "defaultContent": "" },
{ "data": "updateDateTime", "defaultContent": "" }
],
"columnDefs": [
{ "targets": 0, "checkboxes": { "selectRow": true } }
],
"select": {
"style": "multi"
},
"order": [[1, "asc"]],
"fnInitComplete": function() {
$("#omnitureCodeSection").show();
}
});
};
You may need to grab your DataTables object into a variable before using that:
var t_OmnitureCode = $("#tbl_omnitureCode").DataTable();
var rows_selected = t_OmnitureCode.column(0).checkboxes.selected();
And, by the way, your method of populating DataTable with external ajax-call is suboptimal. There's an ajax option for that purpose where you can specify all the necessary parameters and get better integration with DataTables API and better performance (as you don't really need to destroy and create your DataTable upon each refresh).
You would simply need to trigger .ajax.reload() whenever you need to refresh your table data.
It's a matter of scope : You declare the variable table inside $(document).ready function.
You may want to put it outside in the global scope :
var table;
$(document).ready(function() {
table = $('#example').DataTable({
...
});

Event only fires once when making Ajax request in jQuery

I have a couple of drop downs that are populated from SharePoint using SPServices. This part works great. But then, I have a button that on click loads data from SharePoint and uses the dropdown texts as filter to fetch the data that will populate a table using the DataTables plugin. This part works only once; if I click the button again, nothing happens.
This is how I populate the dropdowns:
$(document).ready(function () {
var theYear; // Selected Year
var theRO; // Selected RO
//Fills the Dropdown lists (Year and RO)
$().SPServices({
operation: "GetListItems",
async: false,
listName: "{ListID}",
CAMLViewFields: "<ViewFields><FieldRef Name='Fiscal_x0020_Year' /><FieldRef Name='Regional_x0020_Office' /></ViewFields>",
completefunc: function (xData, Status) {
//Add Select Value option
$("#dropdown").prepend($('<option>', {
value: '',
text: 'Select Fiscal Year'
}));
$("#dropdownRO").prepend($('<option>', {
value: '',
text: 'Select Regional Office'
}));
//Fetching Data from SharePoint
$(xData.responseXML).SPFilterNode("z:row").each(function () {
var dropDown = "<option value='" + $(this).attr("ows_Fiscal_x0020_Year") + "'>" + $(this).attr("ows_Fiscal_x0020_Year") + "</option>";
var dropDownRO = "<option value='" + $(this).attr("ows_Regional_x0020_Office") + "'>" + $(this).attr("ows_Regional_x0020_Office") + "</option>";
$("#dropdown").append(dropDown);
$("#dropdownRO").append(dropDownRO);
/////////////Deletes duplicates from dropdown list////////////////
var usedNames = {};
$("#dropdown > option, #dropdownRO > option").each(function () {
if (usedNames[this.text]) {
$(this).remove();
} else {
usedNames[this.text] = this.value;
}
});
////Deletes repeated rows from table
var seen = {};
$('#myTable tr, #tasksUL li, .dropdown-menu li').each(function () {
var txt = $(this).text();
if (seen[txt]) $(this).remove();
else seen[txt] = true;
});
});
} //end of completeFunc
}); //end of SPServices
$('.myButton').on('click', function () {
run()
});
}); //End jQuery Function
This is the function I need to run every time I click on "myButton" after changing my selection in the dropdowns:
function run() {
theYear = $('#dropdown option:selected').text(); // Selected Year
theRO = $('#dropdownRO option:selected').text(); // Selected RO
var call = $.ajax({
url: "https://blah-blah-blah/_api/web/lists/getByTitle('Consolidated%20LC%20Report')/items()?$filter=Fiscal_x0020_Year%20eq%20'" + theYear + "' and Regional_x0020_Office eq '" + theRO + "'&$orderby=Id&$select=Id,Title,Fiscal_x0020_Year,Notices_x0020_Received,Declined_x0020_Participation,Selected_x0020_Field_x0020_Revie,Selected_x0020_File_x0020_Review,Pending,Pending_x0020_Previous_x0020_Yea,Controversial,GFP_x0020_Reviews,NAD_x0020_Appeals,Mediation_x0020_Cases,Monthly_x0020_Cost_x0020_Savings,Monthly_x0020_Expenditure,Regional_x0020_Office,Month_Number", //Works, filters added

I'm not a programmer, I'm just trying to learn. I would appreciate any help. Thanks in advance
I would guess that you are replacing the part of the page where the button lives. (you really need to format your code more neatly for SO... use JSFiddle.net and their TidyUp button).
If that is the case you need to use a delegated event handler:
$(document).on('click', '.myButton', function () {
run()
});
This listens at a static ancestor of the desired node, then runs the selector when the event occurs, then it applies the function to any matching elements that caused the event.
document is the fallback parent if you don't have a convenient ancestor. Do not use 'body' for delegated events as it has odd behaviour.

invoke javascript on button click of a datatable row

Im using dataTable and I have the following:
var oTable = $('#example').dataTable({
bProcessing: true,
sAjaxSource: "/Cart/addresses",
'iDisplayLength': 5,
aaSorting: [],
aoColumns: [
{ "mData": "Contact" },
{ "mData": "Address" },
{ "mData": "Postcode" },
{
"mData": null,
"mRender": function (data, type, full) {
return '<button type="button" class="btn btn-success use-address" onclick="doFunction();" role="button" data-adcode="' + full.ADCode + '">' + 'Use Address' + '</button>';
}
}
]
});
I have tried the following, i basically want to be bale to use adcode when the button is clicked:
$('.use-address').click(function () {
var adccode = $(this).data("adcode");
});
function doFunction()
{
var adccode = $(this).data("adcode");
}
This wont work, in firebug it doesnt hit either of these.
Note the datatable is added dynamically (after clicking a button.)
Any ideas why it aint working?
Thanks
Try to use event delegation here:
$('#example').on('click','.use-address',function () {
var adccode = $(this).data("adcode");
});

jQuery Datatables.net - refresh table - getting null sAjaxSource

I have the following function which should update a datatable in my ASP.NET site master page:
function refreshTable(oTable) {
var table = $(oTable).dataTable();
var oSettings = table.fnSettings();
//Retrieve the new data with $.getJSON. You could use it ajax too
$.getJSON(oSettings.sAjaxSource, null, function (json) {
table.fnClearTable(this);
for (var i = 0; i < json.aaData.length; i++) {
table.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
table.fnDraw();
});
}
This function is then called to refresh a table if an attachment is added to the site - this is the datatable settings that it should refresh.
var DeleteClicked = false;
var oTable;
$(document).ready(function () {
oTable = $('#infoTable').dataTable({
"aaSorting": [[6, "desc"]],
"bProcessing": true,
"sAjaxSource": '/Web/Handlers/infoTableHandler.ashx',
"aoColumns": [
{ "mData": "ID", "bVisible": false },
{ "mData": "Type" },
{ "mData": "Received" },
{
"mData": "Action", "sWidth": "100px", "mRender": function (data, type, row) {
var id = row.ID;
return "<input type=button id=" + id + " onclick='DeleteFile(" + id + ")' class=buttonBlue value=Delete />";
},
},
{ "mData": "IsImage", "bVisible": false }
],
"bDeferRender": true,
});
However - if I open Developer Tools in Chrome I get an error message saying sAjaxSource is null so i cannot then get the value from it - so oSettings is null and then I cannot get access to the sAjaxSource - anyone see anything wrong here?
you're basically reinitializing your dataTable in the first row of refreshTable. Try instead:
function refreshTable() {
var oSettings = oTable.fnSettings();
...
}
and refer directly to the global oTable instead of your local table variable
