Select2 group with Infinite scroll

I am using select2 group option with infinite scroll and data are coming by Ajax calling per page 10. Here is some problem arises, suppose user 1 has 15 data and user 2 has 15 data, at first 10 data are coming from user 1 and in next page 10 (5 data for user1 and 5 data for user2). no problem for data getting but the problem is user 1 group showing double. How can I prevent double display to my select2 options group? Has there any way to make an option group again?

Demo

Just try to use the following code
templateResult: function(data) {
if (typeof data.children != 'undefined') {
$(".select2-results__group").each(function() {
if (data.text == $(this).text()) {
return data.text = '';
}
});
}
return data.text;
}
NOTE: Need to group from server side, Other wise you have to make master details from client side.

the accepted answer didn't work for me and I don't see why should that work. A return in the $.each will not return from the templateResult() function.
Here is an approach that worked for me.
It is not necessary to build a nested list by getNestedChildren(list) on javascript side. It is much easier to build it on server side instead.
The appearance of search results in the dropdown (options and the optgroups) can be customized by using the templateResult option. I removed the duplicated optgroups and labels by this option.
check the templateResult: formatOptions, part of the code
$(document).ready(function() {
$("#pictures_tag_input").select2({
placeholder: "Search for options",
templateResult: formatOptions,
ajax: {
url: "https://jsonplaceholder.typicode.com/users/1/todos",
dataType: "json",
global: false,
cache: true,
delay: 250,
minimumInputLength: 2,
data: function(params) {
return {
q: params.term,
_page: params.page || 1,
_limit: 10
};
},
processResults: function(data, params) {
params.page = params.page || 1;
return {
results: data,
pagination: {
more: true
}
};
} //end of process results
} // end of ajax
});
function formatOptions(item, container, $el) {
// optgroups section
if (item.children && item.children.length > 0) {
// don't format the repeated optgroups!
if ($(".select2-results__group").text() === item.text) {
return;
}
if ($('[aria-label="' + item.text + '"]').length > 0) {
return;
}
// the first occasion of the given optgroup
return $el;
}
// options section
// here you can implement your own logic
// if you want to customise the output of the options
$el.addClass('something-special-result result');
return $el;
}
});

maybe the problem is a source of a data
You call user 1 .... server return a 1
You call user 2 .... server return a 1
You call user 3 .... server return a 2
You call user 4 .... server return a 2
You call user 5 .... server return a 3
You call user 6 .... server return a 3
curent_user = 1;
$(document).ready(function() {
http: $("#pictures_tag_input").select2({
placeholder: "Search for options",
ajax: {
url: "https://jsonplaceholder.typicode.com/users/1/todos",
dataType: "json",
global: false,
cache: false,
minimumInputLength: 2,
data: function(params) {
console.log("params",params || 1);
return {
q: params.term, // search term
_page: curent_user,
_limit: 10 // page size
};
},
processResults: function(data, params) {
curent_user += 2;
var datx = getNestedChildren(data);
console.log("data: ", data);
return {
results: datx,
pagination: {
more: true
}
};
} //end of process results
} // end of ajax
});
function getNestedChildren(list) {
var roots = [];
for (i = 0; i < list.length; i += 1) {
node = list[i];
if (roots.length === 0) {
var obj = {
text: "User " + node.userId,
children: [{ id: node.id, text: node.title }]
};
roots.push(obj);
} else {
var obj = {
text: "User " + node.userId,
children: [{ id: node.id, text: node.title }]
};
var rootArray = $.map(roots, function(val, i) {
var vl = "User " + node.userId;
if (val.text === vl) return val;
else return undefined;
});
if (rootArray.length > 0) {
var obj1 = {
id: node.id,
text: node.title
};
rootArray[0].children.push(obj1);
} else {
roots.push(obj);
}
}
}
return roots;
}
});
so if you skip a one step
You call user 1 .... server return a 1
You call user 3 .... server return a 2
You call user 5 .... server return a 3

I just found a better solution which does not result in a (duplicated) optgroup being rendered as an empty option:
processResults: function( json, params ){
setTimeout( function() {
var $prevOptions = false;
var $prevGroup = false;
// loop
$('.select2-results__option[role="group"]').each(function(){
// vars
var $options = $(this).children('ul');
var $group = $(this).children('strong');
// compare to previous
if( $prevGroup && $prevGroup.text() === $group.text() ) {
$prevOptions.append( $options.children() );
$(this).remove();
return;
}
// update vars
$prevOptions = $options;
$prevGroup = $group;
});
}, 1 );
return json;
}
Advanced Custom Fields uses the exact same code for their WordPress plugin in order to fix this issue, ajax-load and group posts from different post-types.

Integrating Braintree Client token into braintree.client.create

I have limited experience working with JavaScript and am attempting to pass a client token generated on my server into the braintree client create of Braintree's javascript code. I do not know how to pass the ClientToken out of the jQuery post and into the authorization section of braintree.client.create. A portion of my code is below:
<script src="https://js.braintreegateway.com/web/3.34.0/js/client.min.js"></script>
<script src="https://js.braintreegateway.com/web/3.34.0/js/hosted-fields.min.js"></script>
<script src="https://www.paypalobjects.com/api/checkout.js" data-version-4></script>
<script src="https://js.braintreegateway.com/web/3.34.0/js/paypal-checkout.min.js"></script>
<script>
var form = document.querySelector('#register-form');
var submit = document.querySelector('input[type="submit"]');
var ClientToken;
var authPosting = jQuery.post('/path/to/php_scripts/getClientToken.php');
authPosting.done(function( data ) {
ClientToken = data;
console.log(ClientToken);
});
braintree.client.create({
authorization: 'ClientToken'
}, function (clientErr, clientInstance) {
if (clientErr) {
console.error(clientErr);
return;
}
braintree.hostedFields.create({
client: clientInstance,
styles: {
'input': {
'font-size': '15px',
'font-family': 'roboto, verdana, sans-serif',
'font-weight': 'lighter',
'color': 'black'
},
':focus': {
'color': 'black'
},
'.valid': {
'color': 'black'
},
'.invalid': {
'color': 'black'
}
},
fields: {
number: {
selector: '#card-number',
placeholder: ''
},
cvv: {

expirationDate: {

placeholder: 'MM/YY'
},
postalCode: {

}
}
}, function(err, hostedFieldsInstance) {
if (err) {
console.error(err);
return;
}
function findLabel(field) {
return jQuery('.hosted-field--label[for="' + field.container.id + '"]');
}
hostedFieldsInstance.on('focus', function (event) {
var field = event.fields[event.emittedBy];
findLabel(field).addClass('label-float').removeClass('filled');
jQuery(".error-msg").hide();
});
// Emulates floating label pattern
hostedFieldsInstance.on('blur', function (event) {
var field = event.fields[event.emittedBy];
var label = findLabel(field);
if (field.isEmpty) {
label.removeClass('label-float');
} else if (field.isValid) {
label.addClass('filled');
} else {
label.addClass('invalid');
}
});
hostedFieldsInstance.on('empty', function (event) {
var field = event.fields[event.emittedBy];
findLabel(field).removeClass('filled').removeClass('invalid');
});
hostedFieldsInstance.on('validityChange', function (event) {
var field = event.fields[event.emittedBy];
var label = findLabel(field);
if (field.isPotentiallyValid) {
label.removeClass('invalid');
} else {
label.addClass('invalid');
}
});
//Submit function
jQuery("#register-form").validate({
submitHandler: function(form) {
event.preventDefault();
hostedFieldsInstance.tokenize(function (err, payload) {
if (err) {
if (err.code === 'HOSTED_FIELDS_FIELDS_EMPTY') {
var msg = "All credit card fields are required.";
jQuery(".error-msg").text(msg);
jQuery(".error-msg").show();
} else if (err.code === 'HOSTED_FIELDS_FIELDS_INVALID') {
var invalidFields = err.details.invalidFieldKeys;
invalidFields.forEach(function (field) {
if (field == "number") {
var myid = "card-number";
var myobj = "credit card number";
} else if (field == "expirationDate") {
var myid = "expiration-date";
var myobj = "expiration date";
}
jQuery("#" + myid).append("<div class='error-msg'>Please enter a valid " + myobj + ".</div>");
});
} else {
var msg = "There was an error on the form."
alert (msg);
}
return;
}
vfirst = jQuery( "input#firstname" ).val(),
vlast = jQuery( "input#lastname" ).val(),
vemail = jQuery( "input#email" ).val(),
vproof = jQuery( "input[name='proof']" ).val(),
vprice = jQuery( "tr#total td.price" ).data('price'),
vcourse = 1950,
vnonce = 'fake-valid-nonce',
url = '/path/to/php_scripts/placeOrder.php';
// This is where you would submit payload.nonce to your server
// alert('Submit your cc nonce to your server here!');
});
//form.submit();
}
});
});
....more code below....
</script>
Any suggestions would be greatly appreciated.

Answering my own question:
CLIENT_AUTHORIZATION = jQuery.parseJSON(jQuery.ajax({
url: "/path/to/php_scripts/TokenScript.php",
dataType: "json",
async: false
}).responseText);
braintree.client.create({
authorization: CLIENT_AUTHORIZATION.token
}, function (clientErr, clientInstance) {
if (clientErr) {
console.error(clientErr);
return;
} code continues.....
The CLIENT_AUTHORIZATION.token is whatever the token was named on the client authorization script.

Datatables select first row after first load and reload

I'm using datatables and I have to select the first row of table.
The problem is select the first row when the table are reload (the table show the rooms of a building, so user can change the building).
This is my code:
function showRoom(idBuilding){
document.getElementById("roomTable").removeAttribute("style");
if ( ! $.fn.DataTable.isDataTable( '#roomTable' ) ) {
roomTable = $('#roomTable').DataTable({
responsive:true,
select: true,
"autoWidth": false,
"language": {
"emptyTable": "No room available!"
},
"ajax":{
"url": "/buildings/"+ idBuilding + "/rooms/",
"data": function ( d ) {
d.idRoomType = idRoomType;
},
"dataSrc": function ( json ) {
if (typeof json.success == 'undefined')
window.location.href = "/500";
else if (json.success){
return json.result.data;
}else{
notifyMessage(json.result, 'error');
return "";
}
},
"error": function (xhr, error, thrown) {
window.location.href = "/500";
}
},
"columns": [
{ "data": "name" },
{ "data": "capacity"},
{data:null, render: function ( data, type, row ) {
var string ="";
for (index = 0; index < data.accessories.length; ++index){
string = string + '<i aria-hidden="true" class="'+ data.accessories[index].icon+'" data-toggle="tooltip" title="'+data.accessories[index].name+'"style="margin-right:7px;" ></i>';
}
return string;
}
},
],
"fnInitComplete": function(oSettings, json) {
if (roomTable.rows().any()){
roomTable.row(':eq(0)').select();
selectedRoom(0);
}
initializeCalendar();
}
});
}
else {
roomTable.ajax.url("/buildings/"+ idBuilding + "/rooms/?idRoomType=" + idRoomType).load(selectFirstRow());
}
roomTable.off('select')
.on( 'select', function ( e, dt, type, indexes ) {
selectedRoom(indexes);
} );
roomTable.off('deselect').on( 'deselect', function ( e, dt, type, indexes ) {
reservationForm.room = -1;
$('#calendar').fullCalendar('option', 'selectable', false);
$("#calendar").fullCalendar("refetchEvents");
} );
}
function selectFirstRow(){
if (roomTable.rows().any()){
roomTable.row(':eq(0)').select();
selectedRoom(0);
}
initializeCalendar();
}
function selectedRoom(index){
var room = roomTable.rows( index ).data().toArray()[0];
reservationForm.room = room.idRoom;
$('#calendar').fullCalendar('option', 'minTime', room.startTime);
$('#calendar').fullCalendar('option', 'maxTime', room.endTime);
$('#calendar').fullCalendar('option', 'selectable', true);
$("#calendar").fullCalendar("refetchEvents");
}
On the first load all work fine, but when
roomTable.ajax.url("/buildings/"+ idBuilding + "/rooms/?idRoomType=" + idRoomType).load(selectFirstRow());
is called it seems to select the row before reload the table, so I have no row select (keep select the row of first load but now it is not visible).
Do you have idea how can I select on the load after?
UPDATE: the temporary solution is to use destroy: true but I would like a better solution like this:
if ( ! $.fn.DataTable.isDataTable( '#roomTable' ) ) {
roomTable = $('#roomTable').DataTable({
destroy: true, //it is useful because with standard code I have problem with first row selection, now it create the table each time
responsive:true,
select: true,
"autoWidth": false,
"language": {
"emptyTable": "No room available!"
},
"ajax":{
"url": "/buildings/"+ building.idBuilding + "/rooms/",
"data": function ( d ) {
d.idRoomType = idRoomType;
},
"dataSrc": function ( json ) {
if (typeof json.success == 'undefined')
window.location.href = "/500";
else if (json.success){
return json.result.data;
}else{
notifyMessage(json.result, 'error');
return "";
}
},
"error": function (xhr, error, thrown) {
window.location.href = "/500";
}
},
"fnDrawCallback": function(oSettings) {
if (roomTable.rows().any()){
roomTable.row(':eq(0)').select();
selectedRoom(0);
}
},
"fnInitComplete": function() {
initializeCalendar();
},
"columns": [
{ "data": "name" },
{ "data": "capacity"},
{data:null, render: function ( data, type, row ) {
var string ="";
for (index = 0; index < data.accessories.length; ++index){
string = string + '<i aria-hidden="true" class="'+ data.accessories[index].icon+'" data-toggle="tooltip" title="'+data.accessories[index].name+'"style="margin-right:7px;" ></i>';
}
return string;
}
},
],
});
}
else {
roomTable.ajax.url("/buildings/"+ idBuilding + "/rooms/?idRoomType=" + idRoomType).load(selectFirstRow());
}
But fnDrawCallback is called before ajax so I don't have the value, datatables keep on loading...

The fnInitComplete callback is called only when the datatable is initialized, so only once. You can use the fnDrawCallback, which is called every time the datatables redraws itself.
Just change fnInitComplete to fnDrawCallback. More about datatable callbacks (legacy version) here.

kendo grid inline edit dropdown will not expand on tab navigation

I'm having an issue with Kendo Grid in Angular where the custom drop down I've implemented will not open when tab navigating to that column. The built in text and number editor fields are editable on tab navigation but my custom drop down will not expand. I have to click on it to get the drop down effect.
My goal here is to allow the user to log an an entire row of data without having to take their hands off the keyboard.
My column is defined like so:
gridColumns.push({
field: currentField.FieldName.replace(/ /g, "_"),
title: currentField.FieldName,
editor: $scope.dropDownAttEditor,
template: function (dataItem) {
return $scope.dropDownTemplate(dataItem, currentField.FieldName);
}
});
My gridOptions are defined as follows:
$scope.gridOptions = {
dataSource: new kendo.data.DataSource({
transport: {
read: {
url: appconfig.basePath + '/api/DrillHoleManager/DrillHoleInterval',
type: 'POST',
contentType: 'application/json'
},
update: {
url: appconfig.basePath + '/api/DrillHoleManager/DrillHoleIntervalUpdate',
type: 'POST',
contentType: 'application/json'
},
parameterMap: function (data, operation) {
if (operation === "read") {
data.DrillHoleId = $scope.entity.Id;
data.DrillHoleIntervalTypeId = $stateParams.ddhinttypeid;
// convert the parameters to a json object
return kendo.stringify(data);
}
if (operation === 'update') {
// build DrillHoleIntervalDto object with all ATT/CMT values to send back to server
var drillHoleInterval = { Id: data.Id, Name: data.Name, From: data.From, To: data.To };
drillHoleInterval.Attributes = [];
drillHoleInterval.Comments = [];
var attributeFields = $.grep($scope.currentFields, function (e) { return e.DrillHoleTabFieldType == DrillHoleTabFieldTypeEnum.IntervalAttribute });
$.each(attributeFields, function (idx, attributeField) {
drillHoleInterval.Attributes.push({
Id: attributeField.AttributeDto.Id,
LookupId: data[attributeField.FieldName.replace(/ /g, "_")]
});
});
var commentFields = $.grep($scope.currentFields, function (e) { return e.DrillHoleTabFieldType == DrillHoleTabFieldTypeEnum.IntervalComment });
$.each(commentFields, function (idx, commentField) {
drillHoleInterval.Comments.push({
Id: commentField.CommentDto.Id,
Value: ((data[commentField.FieldName.replace(/ /g, "_")] != "") ? data[commentField.FieldName.replace(/ /g, "_")] : null)
});
});
return kendo.stringify(drillHoleInterval);
}
// ALWAYS return options
return options;
}
},
schema: { model: { id : "Id" }},
serverPaging: false,
serverSorting: false,
serverFiltering: false
//,autoSync: true
}),
columns: gridColumns,
dataBound: onDataBound,
autoBind: false,
navigatable: true,
scrollable: false,
editable: true,
selectable: true,
edit: function (e) {
var grid = $("#ddhintgrid").data("kendoGrid");
//grid.clearSelection();
grid.select().removeClass('k-state-selected');
// select the row currently being edited
$('[data-uid=' + e.model.uid + ']').addClass('k-state-selected');
e.container[0].focus();
}
};
Here is a custom event to handle the 'Tab' keypress. The point of this is I want a new record automatically added to the grid if the user presses 'Tab' at the end of the last line:
$("#ddhintgrid").keydown(function (e) {
if (e.key == "Tab") {
var grid = $("#ddhintgrid").data("kendoGrid");
var data = grid.dataSource.data();
var selectedItem = grid.dataItem(grid.select());
var selectedIndex = null
if (selectedItem != null) {
selectedIndex = grid.select()[0].sectionRowIndex;
if (selectedIndex == data.length - 1) { // if the bottom record is selected
// We need to manually add a new record here so that the new row will automatically gain focus.
// Using $scope.addRecord() here will add the new row but cause the grid to lose focus.
var newRecord = { From: grid.dataSource.data()[selectedIndex].To };
var currentCmtFields = $.grep($scope.currentFields, function (e) { return e.DrillHoleTabFieldType == DrillHoleTabFieldTypeEnum.IntervalComment; });
$.each(currentCmtFields, function (idx, currentCmtField) {
newRecord[currentCmtField.FieldName.replace(/ /g, "_")] = null;
});
grid.dataSource.insert(data.length, newRecord);
// edit the new row
grid.editRow($("#ddhintgrid tr:eq(" + (data.length) + ")"));
}
}
}
});
Here is my template for the drop down column:
$scope.dropDownTemplate = function (dataItem, fieldName) {
var currentLookups = $.grep($scope.currentFields, function (e) { return e.FieldName == fieldName; })[0].AttributeDto.Lookups;
var selectedLookup = $.grep(currentLookups, function (e) { return e.Id == dataItem[fieldName.replace(/ /g, "_")]; })[0];
// With the custom dropdown editor when going from null to a value the entire lookup object (id, name) is placed in the
// dataItem[field_name] instead of just the id. We need to replace this object with just the id value and return the name of
// the lookup to the template.
if (typeof selectedLookup == 'undefined' && dataItem[fieldName.replace(/ /g, "_")] != null) {
selectedLookup = angular.copy(dataItem[fieldName.replace(/ /g, "_")]);
dataItem[fieldName.replace(/ /g, "_")] = selectedLookup.Id;
}
if (selectedLookup != null && selectedLookup != '') {
return selectedLookup.Name;
}
else {
return '';
}
};
And finally here is the custom editor for the drop down column:
$scope.dropDownAttEditor = function (container, options) {
var editor = $('<input k-data-text-field="\'Name\'" k-data-value-field="\'Id\'" k-data-source="ddlDataSource" data-bind="value:' + options.field + '"/>')
.appendTo(container).kendoDropDownList({
dataSource: $.grep($scope.currentFields, function (e) { return e.FieldName == options.field.replace(/_/g, ' '); })[0].AttributeDto.Lookups,
dataTextField: "Name",
dataValueField: "Id"
});
};
I know this is a lot to take in but if you have any questions just let me know.
My ultimate goal is that I want the user to be able to navigate the grid using the 'Tab' key and edit every field without having to use the mouse.

Cannot reload data in Fuelux Datagrid

I have tried to reload the data populated by an ajax call but I cant get it to work, it shows the old data even after using the reload method. The thing is that if I change some variables to populate a different data and try to call the following code without refreshing the page it does not reload the updated data =/ Here is my code:
function populateDataGrid() {
$.ajaxSetup({async: false});
var gridinfo="";
$.post("lib/function.php",{activity: activity, shift: shift, date: date},
function (output){
gridinfo = JSON.parse(output);
});
$.ajaxSetup({async: true});
// INITIALIZING THE DATAGRID
var dataSource = new StaticDataSource({
columns: [
{
property: 'id',
label: '#',
sortable: true
},
{
property: 'date',
label: 'date',
sortable: true
},
....
],
formatter: function (items) {
var c=1;
$.each(items, function (index, item) {
item.select = '<input type="button" id="select'+c+'" class="select btn" value="select" onclick="">';
c=c+1;
});
},
data: gridinfo,
delay:300
});
$('#grid').datagrid({
dataSource: dataSource
});
$('#grid').datagrid('reload');
$('#modal-fast-appointment-results').modal({show:true});
}

I found a solution... I had to create a new DataSource (lets call it "AjaxDataSource") and add the ajax request functionality within the data constructor:
(function (root, factory) {
if (typeof define === 'function' && define.amd) {
define(['underscore'], factory);
} else {
root.AjaxDataSource = factory();
}
}(this, function () {
var AjaxDataSource = function (options) {
this._formatter = options.formatter;
this._columns = options.columns;
this._delay = options.delay || 0;
this._data = options.data;
};
AjaxDataSource.prototype = {
columns: function () {
return this._columns;
},
data: function (options, callback) {
var self = this;
setTimeout(function () {
var data;
$.ajax({
url: 'getdata.php',
type: 'POST',
data: 'param1:param1,param2,param2,...,paramN:paramN', // this is optional in case you have to send some params to getdata.php
dataType: 'json',
async: false,
success: function(result) {
data = result;
},
error: function(data){
//in case we want to debug and catch any possible error
// console.log(data);
}
});
// SEARCHING
if (options.search) {
data = _.filter(data, function (item) {
var match = false;
_.each(item, function (prop) {
if (_.isString(prop) || _.isFinite(prop)) {
if (prop.toString().toLowerCase().indexOf(options.search.toLowerCase()) !== -1) match = true;
}
});
return match;
});
}
var count = data.length;
// SORTING
if (options.sortProperty) {
data = _.sortBy(data, options.sortProperty);
if (options.sortDirection === 'desc') data.reverse();
}
// PAGING
var startIndex = options.pageIndex * options.pageSize;
var endIndex = startIndex + options.pageSize;
var end = (endIndex > count) ? count : endIndex;
var pages = Math.ceil(count / options.pageSize);
var page = options.pageIndex + 1;
var start = startIndex + 1;
data = data.slice(startIndex, endIndex);
if (self._formatter) self._formatter(data);
callback({ data: data, start: start, end: end, count: count, pages: pages, page: page });
}, this._delay)
}
};
return AjaxDataSource;
}));
After defining the new DataSource, we just need to create it and call the datagrid as usual:
function populateDataGrid(){
// INITIALIZING THE DATAGRID
var dataSource = new AjaxDataSource({
columns: [
{
property: 'id',
label: '#',
sortable: true
},
{
property: 'date',
label: 'date',
sortable: true
},
....
],
formatter: function (items) { // in case we want to add customized items, for example a button
var c=1;
$.each(items, function (index, item) {
item.select = '<input type="button" id="select'+c+'" class="select btn" value="select" onclick="">';
c=c+1;
});
},
delay:300
});
$('#grid').datagrid({
dataSource: dataSource
});
$('#grid').datagrid('reload');
$('#modal-results').modal({show:true});
}
So now we have our datagrid with data populated via ajax request with the ability to reload the data without refreshing the page.
Hope it helps someone!
