Datatables onchange event for input field - datatables

I have input fields in my project with a special class (date_input_field). On change these fields format the data that user has entered. The problem is that these fields work fine absolutely everywhere EXCEPT DataTables. I tried rowCallback in my datatable itself, but it didn't help. Why? And how can I fix that?
$(".date_input_field").change(function () {
...format the data
});
var table2 = $("#stopsTable").DataTable({
ajax: {
url: "/api/stops/" + confirmationId,
dataSrc: ""
},
columns: [
{
data: "date1",
render: function (data) {
var arr = data.split("T")[0].split("-");
return "<input class='form-control date_input_field' type='text' value='" + arr[2] + "-" + arr[1] + "-" + arr[0]+"'/>" ;}}
],
order: [[0, "asc"]],
scrollY: '50vh',
scrollCollapse: true,
paging: false,
rowCallback: function (row, data) {
$(row).css("cursor", "pointer");
$(".date_input_field").change(function () {
$(this).attr("value", "01");
});
}
});

Sorry for stupid question.
I tried the code below and it works.
rowCallback: function (row, data) {
$(row).css("cursor", "pointer");
$(row).on("change", ".date_input_field", function () {
var input = $(this);
input.val("1111111111");
});
}

when the user edits the input on the cell this will console log the edited field with its input id rowCallback is the function which can trigger / perform on any cell inside the datatable
var datatable = $('#datatable').DataTable({
rowCallback: function (row, data) {
$(row).on("change", ".edit_qty_class", function () {
var input = $(this);
input.attr('value', input.val())
console.log()
console.log($(this).attr('id'), input.val())
});
},
columns: [{
data: "id",
render: function(data, type, full, meta) {
return meta.row + 1
}
},
{
data: "id",
title:"QTY SEND",
render: function(data, type, full, meta) {
var dataID = 'edit_qty_' + data.id
return `<input type="number" id="`+dataID+`" name="`+dataID+`" class="edit_qty_class" value="0">`
}
},
})

Single dropdown filtering for Datatable

I've been struggling for a few days now, trying to get a single dropdown to filter my table. Upon selection of the eraId, the columns should be refreshed to only show the columns of the selected eraId.
This is how my tables looks like:
I've read a lot of examples on Datatables website or forums but I can't seem to find something working.
I have managed to create a dropdown menu containing the different EraIds as filter (I have simplified the example below with only 3 eraIds) but after selecting an entry in the dropdown, the table gets empty and the column list is not refreshed.
I think the problem is that I first retrieve the columns names, based on the eraId and then draw the table accordingly, displaying only the resources from the specific eraId. I have tried several things but did not manage.
Ideally I should callback getPlayerResourceTable with the selected eraId or update the column list with the resources on the selected eraId.
Javascript:
var columns = [];
function getPlayerResourceTable($selectedEraId) {
$.ajax({
type: "POST",
url: "./graphs.php",
data: { call_function : 'getResourceTableColumns', eraId: $selectedEraId},
success: function (data) {
data = JSON.parse(data);
columnNames = Object.keys(data.data);
for (var i in data.data) {
columns.push({data: data.data[i],
title: data.data[i]});
}
$('#playerResourceTable').DataTable( {
processing: true,
serverSide: false,
filter: true,
columns: columns,
ajax: {
url: './graphs.php',
type: 'POST',
data: { call_function: 'playerResourceTable', column_fields : data.data, eraId: $selectedEraId}
},
initComplete: function () {
this.api().columns( 0 ).every( function () {
var column = this;
var select = $('<select><option value=""></option></select>')
.appendTo( $("#playerResourceTablesWrapper .dataTables_filter"))
.on( 'change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column.search( this.value ).draw();
} );
select.append( '<option value="1">Era 1</option>' )
select.append( '<option value="2">Era 2</option>' )
select.append( '<option value="3">Era 3</option>' )
} );
}
});
}
});
}
$(document).ready(function() {
$selectedEraId = 1;
getPlayerResourceTable($selectedEraId);
} );
PHP:
getResourceTableColumns returns the column list with query similar to SELECT columnName FROM ages WHERE eraId = ?
playerResourceTable returns the resources for each column (type of resource) with query similar to SELECT ".$field_list." FROM user_resources
I also thought of removing WHERE eraId = ? in my MySQL query and filtering the columns on the client side but no luck either.
I eventually ended up separating both functions and destroying/re-creating the table when changing Era.
function getColumns($selectedEraId) {
var columns = [];
$.ajax({
type: "POST",
url: "./graphs.php",
data: { call_function : 'getResourceTableColumns', eraId: $selectedEraId},
success: function (data) {
data = JSON.parse(data);
for (var i in data.data) {
columns.push({data: data.data[i],
title: data.data[i]});
}
if ( $.fn.dataTable.isDataTable( '#playerResourceTable' ) ) { // If the table already exists, detroy it before creating it again
$('#playerResourceTable').DataTable().destroy();
}
getPlayerResourceTable($selectedEraId, columns); // Will recreate the table with the new columns
}
});
}
function getPlayerResourceTable($selectedEraId, columns_to_show) {
$city_id = 91;
$playerResourceTable = $('#playerResourceTable').DataTable( {
processing: true,
serverSide: false,
filter: true,
columns: columns_to_show,
ajax: {
url: './graphs.php',
type: 'POST',
data: { call_function: 'playerResourceTable', column_fields : columns_to_show, city_id : parseInt($city_id)}
},
initComplete: function () {
this.api().columns( 0 ).every( function () {
var column = this;
var select = $('<select id="selectEraId" ><option value=""></option></select>')
.appendTo( $("#playerResourceTablesWrapper .dataTables_filter"))
.on( 'change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column.search( this.value ).draw();
} );
dropdown_string = getEraDropdown($selectedEraId);
} );
$('#selectEraId').on('change', function() {
$selectedEraId = this.value;
columns_to_show = getColumns($selectedEraId);
});
}
});
}

Knockout-Kendo Chart - remove and add series

My project is MVC 5, I am using the following to generate a chart with multiple series:
HTML:
<button data-bind="click: addItem">Add</button>
<button data-bind="click: removeItem">Remove</button>
<div data-bind="kendoChart2: { title: { text: 'Graph Sample' },
series: seriesConfig,tooltip: {visible: true,template: '#= series.name #: #= value #'} , seriesDefaults: {
type: 'line',style: 'smooth'}}"> </div>
Javascript
var MainViewModel = function () {
var self = this;
this.Systolic = ko.observableArray([]);
this.Diastolic = ko.observableArray([]);
this.HeartRate= ko.observableArray([]);
$.ajax({
type: "GET",
url: '/Charts/GetChart',
contentType: "application/json; charset=utf-8",
async: false,
cache: false,
dataType: "json",
success: function (result) {
//Diastolic
if (result && result.Systolic.length > 0) {
for (var i = 0; i < result.Systolic.length; i++) {
self.Systolic.push(result.Systolic[i].Systolic);
}
};
....
},
error: function (err) {
alert(err.status + " : " + err.statusText);
}});
this.seriesConfig = ko.observableArray([
{name: "Systolic", data: this.Systolic()},
{name: "Diastolic",data: this.Diastolic()}]);
this.addItem = function() {
this.seriesConfig.push({ name: "Heart Rate", data: this.HeartRate() });
};
this.removeItem = function() {
this.seriesConfig.remove({ name: "Diastolic", data: this.Diastolic() });
};
}.bind(this);
ko.kendo.bindingFactory.createBinding(
{
name: "kendoChart",
bindingName: "kendoChart2",
watch: {
data: function(value) {
ko.kendo.setDataSource(this, value);
},
series: function(value) {
this._sourceSeries = value;
this.refresh();
this.redraw();}
}
});
window.viewModel = new MainViewModel();
ko.applyBindings(window.viewModel);
The chart works great, however can't add or remove series?
Note:
the addItem works, I get the value of the new series:
series: function (value) {
alert(value[2].name);
this.seriesConfig = value;
this.refresh();
this.redraw();
}
I also tried load all series then use the following hide a series:
$("#kendoChart").getKendoChart().options.series[1].visible = false;
$("#kendoChart").getKendoChart().redraw();
Does not work, I think the chart name does not register.
I am not familiar with knockout-kendo, just with knockout in general, so if fixing obvious problem as described below will not work, you might need to refresh bindings. Looking at this example however this is not needed, so most likely you got caught by a simple fact that array's remove performs simple == comparison and it fails to find equal object in the array.
Here is a simplified example (although you might know it already, but just in case):
var a="abc";
var b="abc";
var aa = [1,2,3,"a","b","c"];
var data1 = {name: a, data: aa};
var data2 = {name: b, data: aa};
now, comparison a==b returns true and clearly data slots are the same, however data1==data2 is false. That is because it's a different object.
So in your example in removeItem you create and pass a new object to remove, not the one in the array, so == comparison fails and nothing is removed as that newly created object isn't in your observable array.
I suggest comparing the name only similar to item.age < 18 comparison from knockout.js documentation on observable arrays:
this.seriesConfig.remove( function (item) { return item.name == "Diastolic"; } )
I believe, this should do the trick.

Column Visibility is not restored from a saved state via stateLoadCallback

I have added the Column Visibility button to choose to show or hide certain columns. I'm saving the state in a database, I call the stateSaveCallback function via a click on a button.
I cant find documentation about retrieving data this way, so I just link to the page and pass variables to get the data back from the database, and then load that using stateLoadCallback.
Now all this works fine, EXCEPT the column visibility is not restored. It is in the JSON data being returned though.
Here is my full code:
$(document).ready(function() {
$.extend( jQuery.fn.dataTableExt.oSort, {
"date-uk-pre": function (a){
return parseInt(moment(a, "DD/MM/YYYY").format("X"), 10);

return a - b;
},

return b - a;
}
});

In my case datatables rejects old data according to "stateDuration" and "time" properties..
Solution: ignore state duration
"stateSave": true,
"stateDuration": -1,
Above case:
"visible":"false" may should be "visible":false
After a while of debugging this myself here's what worked for me..
This issue is that all the values in your JSON are strings and they need to be of correct datatypes for the datatables plugin.
Within the "stateSaveCallback" ajax request to save your state I did the following to the json string and then it saved all the values properly which then loaded the state as it should.
"stateSaveCallback": function (settings, data) {
var save_name = $('.save_name').val();
// Send an Ajax request to the server with the state object
$.ajax( {
"url": EE.BASE + "&C=addons_modules&M=show_module_cp&module=ion&method=state_save&action=save&save_name="+save_name,
//"data": data,
"data": JSON.stringify(data), // change to this..
"dataType": "json",
"type": "POST",
"success": function (response)
{
//console.log(response);
}
} );
},

x-editable price format issue

i have an issue in x-editable plugin, how to display prices in correct format in x-editable ? i would like to get the values as in price format like xx,xxx.xx ?
My code is
var editVehiclePrice = function (el, options) {
var options = $.extend(true, {
url: Utils.siteUrl() + 'dashboard/sell_vehicle/inline_vehicle_edit/',
ajaxOptions: {
dataType: 'json'
},
mode: 'inline',
}, options || {
params: function(params) {
params.veh_id = $(this).data('vehid');
return params;
},
success: function(response, newValue) {
if(response.status == 0) return response.msg;
console.log(Utils.numberFormat(newValue,2));
$(response.to_update).text(newValue);
},
validate: function(value) {
if($.trim(value) == '') {
return 'This field is required';
}
}
});
$(el).editable(options);
}
That console.log will display correct format value..but when i update it displays number in normal format.. Please help me
if we want to display any changes after editing, we should add
display: function(value, response) {
var k = Utils.numberFormat(value,2);
$(this).text(k);
},
The price will display in the number format.
Just to add to Anju's reply, Utils.numberFormat(value,2); is not defined. you can replace that with number.toFixed(2).replace(/(\d)(?=(\d{3})+.)/g, '$1,'); or wrap it into a utility function

Jquery Datatables expand row and get detail via Ajax

Is it possible to get the detail for each row through Ajax?
I found a starting point here:
http://datatables.net/release-datatables/examples/api/row_details.html
but it doesn't use ajax.
I'm thinking about modifying fnFormatDetails() function and place the ajax call there.
But i'm looking for another better answer.
Thanks.
It's very simple. All you have to do is put your details in a separate field within the "data" array:
E.g. your JSON might look like as follows:
{
"draw": "${drawId}",
"recordsTotal": "${totalRecords}",
"recordsFiltered": "${filteredRecords}",
"data": [
{
"empName": "${employee.name}",
"empNumber": "${employee.number}",
"empEmail": "${employee.email}",
"extraDetails" : [
["${employee.salary}", "${employee.title}"]
]
}
]
}
Then in your javascript, you can simply access this extra details by using JavaScript arrays. E.g.
var row = employeeTable.row( tr );
var rowData = row.data();
alert(rowData.extraDetails[0][0]);
alert(rowData.extraDetails[0][1]);
You need not to go for ajax if you have the data in your row.
Try oTable.fnGetData(rowIndexor|trNode)
you can try this and it will work.
First: create your datatable.
var table = $('#myTable').DataTable( {
ajax: '/api/staff',
columns: [
{
className: 'details-control',
orderable: false,
data: null,
defaultContent: ''
},
{ data: "name" },
{ data: "position" },
{ data: "office" },
{ data: "salary" }
],
order: [[1, 'asc']] } );
Second: Event handlers
$('#myTable tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row( tr );
if ( row.child.isShown() ) {
row.child.hide();
tr.removeClass('shown');
}
else {
row.child( format(row.data()) ).show();
tr.addClass('shown');
} } );
Third: Ajax request and formatting the response
function format ( rowData ) {
var div = $('<div/>')
.addClass( 'loading' )
.text( 'Loading...' );
$.ajax( {
url: '/api/staff/details',
data: {
name: rowData.name
},
dataType: 'json',
success: function ( json ) {
div
.html( json.html )
.removeClass( 'loading' );
}
} );
return div; }
you can pass any row argument to format method.
