I'm looking to set my own validations on my Adyen payment module. Specifically I want to eliminate people's ability to insert incorrect characters in card holder name field (like emojis, etc).
You are able to customize the validation logic implementing one of the handlers
onChange: (state, component) => {
// triggered at every change
console.error("onChange " + JSON.stringify(state.data));
},
onSubmit: (state, component) => {
// triggered upon submit
console.error("onSubmit " + JSON.stringify(state.data));
// grab holderName
var holderName = state.data.paymentMethod.holderName;
// apply your validation...
if(validationOk) {
makePayment(state.data)
// etc etc
}
}
Check Web Dropin integration guide. Make sure to check which version you are using (to refer to the relevant documentation), however the workflow is similar.

On a web page I wish to display an element which depends on the state of some JavaScript. State like in a state machine. Currently the possible states are these (but I may add more):
input: display some input elements for the user to set. The user can click a button to start some JavaScript processing and move to the working state.
working: display a progress bar informing the user that the script is running. The user can cancel the computation (moving back to the input state) or the computation can end (moving to either the result or error state).
result: display the computation result. The user can go back to input with a button.
error: display the error. The user can go back to input with a button.
The JavaScript part is ready and working, but I'm unsure how to do this in HTML + CSS.
Current solution and its issue
Currently I've been doing it with classes: I set a class to a common ancestor element with the same name of the state and I display the right elements based on it. Something like this:
const parent=document.querySelector("#parent");
let timer=null;
function input(){
parent.classList.remove("working","result","error");
parent.classList.add("input");
}
function run(){
parent.classList.remove("input");
parent.classList.add("working");
timer=setTimeout(result,1500)
}
function stop(){
clearTimeout(timer);
input();
}
function result(){
parent.classList.remove("working");
if(Math.random()>0.5){parent.classList.add("result");}
else{parent.classList.add("error");}
}
input();
#input{display:none;}
#working{display:none;}
#result{display:none;}
#error{display:none;}
#parent.input #input{display:block;}
#parent.working #working{display:block;}
#parent.result #result{display:block;}
#parent.error #error{display:block;}
<div id="parent">
<div id="input">INPUT. RUN</div>
<div id="working">WORKING. STOP</div>
<div id="result">RESULT. RESTART</div>
<div id="error">ERROR. RESTART</div>
</div>
This solution works but it feels unstable: in theory it would be possible for the parent element to have no classes (in which case nothing is displayed) or multiple ones (in which case you'd see multiple states at once). This shouldn't happen, but the only thing preventing it is the correctness of my script.
Question
Are there better ways to implement this idea of states, so that the HTML elements can't end up in inconsistent states?
Let’s consider the role which HTML plays in a state machine on the web. A machine has moving parts, it is dynamic, so the core of any machine on the web must be implemented in Javascript. HTML is useful only to provide the interface between the user and the machine. It’s a subtle distinction but it fundamentally changes the way you write it.
Have you ever used React? React provides the framework to create entire web applications as “state machines”. React’s mantra is “UI is a function of state”. In a React app, you have a single variable which contains the current state, rendering code which builds the UI based on the state, and core code (mostly event handlers) which updates the state.
Even if you don’t want to build in React, you can use the same general idea:
keep the current state in a Javascript variable (typically you’d use an object, but in this case we only need a string)
write a rendering function which reads the state and then builds the appropriate HTML to represent that state
in the event handlers for your links, do any operations which are required, update the state and call the rendering function
let state = null
let timer = null
// core code
const input = () => {
state = 'input'
render()
}
const run = () => {
state = 'working'
render()
timer = setTimeout(result,1500)
}
const stop = () => {
clearTimeout(timer)
state = 'input'
render()
}
const result = () => {
if(Math.random()>0.5)
state = 'result'
else
state = 'error'
render()
}
// rendering code
const render = () => {
let x = state
switch(state) {
case 'input':
x += ' run'
break
case 'working':
x += ' stop'
break
case 'result':
x += ' restart'
break
case 'error':
x += ' restart'
break
}
document.getElementById('container').innerHTML = x
}
// initialisation code
state = 'input'
render()
<div id="container"></div>
I am trying to get Kendo Grid data which is hydrated from client side to a MVC controller method. My view contains several single fields like name, date of birth etc and tabular field which I hooked with a Kendo Grid. Since its a new operation I have no data in the grid ( and other fields) and user enters them from client side.
I have no idea how to proceed on this. Ideally I would like to get this data to a list in my viewmodal. So that when the user hits save, I have all other data and the grid data coming into a controller method.
I am able to successfully bind a list with kendo grid and display it. I have very little experience on JavaScript and Kendo and web programming.
If any of you can point me to the right direction, sample code would be greatly appreciated.
$("#departmet").kendoGrid({
dataSource: dataSource,
height: 250,
scrollable: true,
sortable: true,
filterable: true,
pageable: {
input: true,
numeric: false
},
columns: [
"DepartmentName",
"SubDivision"
]
});
From experience I know their documentation is not easy to navigate. It seems there is the documentation and then the API. The API is usually what you will always want to find. What you will need is the information from here https://docs.telerik.com/kendo-ui/api/javascript/ui/grid. If I understand the question correctly. There are several ways you can achieve posting. You could make use of editor templates. Click the Open in Dojo to get an idea how it looks.
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/editable.template
With this you do not have to worry about modifying the data via javascript. Assuming your grid is surrounded with a form element it will get posted when submitted. Note paging is not accounted for here. Also, this method by default can auto post after each edit. If you don't want this behavior then you will have to have advanced knowledge of the API.....Correction on that last statement. The API is different when dealing with the data all on the client side. Click the Open in Dojo to see it all on the client side. If you are not wanting to use editor templates and want to manage the data editing yourself then you need to use the grid methods provided.
Once you have your grid created. To access the data source of the grid you will need to get the dataSource.
$('#departmet').data('kendoGrid').dataSource;
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource
If you need to use a different data source(or change it) you can use the setDataSource method below(grid function).
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/setdatasource
To add to the data source use the add function to add a new object.
$('#departmet').data('kendoGrid').dataSource.add({ id: 2, name: 'name'});
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/add
It is important with kendo to ALWAYS use the methods provided to change the data source so that the proper events can fire to update the UI accordingly. This includes if you need to set a property on a specific data item. In that case you need to use the set method on the item itself.
After you are done modifying your data. Within javascript get the data and either create DOM elements within a form
//JQuery sudo code example
var data = $("#departmet").data("kendoGrid").dataSource.data();
var dataLen = data.length;
var myForm = $('#my-form'); //Already within DOM
for (var i = 0; i < dataLen; i++) {
var item = data[i];
var idEl = $('<input type="hidden" name="userData[' + i + '].id" />');
idEl.val(item.id);
var nameEl = $('<input type="hidden" name="userData[' + i + '].name" />');
nameEl.val(item.name);
myForm.append(idEl);
myForm.append(nameEl);
}
myForm.submit();
This assumes your controller function(??) on the backend is expecting an array of objects with the property name of userData.
Alternatively, you can post it via ajax. For example, the ajax jquery function. Passing your data as the data of the ajax call.
http://api.jquery.com/jquery.ajax/
Don't want to ramble. Let me know if you need more help.
SO won't let me comment yet so have to add another answer. You will not need to define the data source within the .NET code when dealing with client only data. Just use this.
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
)
If you will have data coming from the backend then you need to use the generic-less constructor and pass in the object else keep what you have.
Html.Kendo().Grid(Model.MyList)
However, if you are preprocessing some client data on the screen that you want to initialize then you will need to do this on ready. Don't worry about the schema part of the data source. It already knows this when you used the .NET MVC wrapper because you gave it the schema(type) via the generic or the parameter provided.
var initialDS= new kendo.data.DataSource({
data: [
{ ActionName: "Some Name", ActionType: "Some Type" }
]
});
$(document).ready(function () {
$('#docworkflow').data('kendoGrid').setDataSource(initialDS);
});
As I mentioned in the other answer. Use the data source functions for adding additional data to the data source. No need to setDataSource each time you want to add. Just
//Assuming you have 2 inputs on the screen the user is entering info into
var nameEntry = $('#action-name').val();
var typeEntry = $('#action-type').val();
$('#docworkflow').data('kendoGrid').dataSource.add({ ActionName: nameEntry , ActionType: typeEntry });
So after some efforts I come up with. But I don't know where to specify the
data in the html code. Is it possible this way?
#(Html.Kendo().Grid <DockData.Action> ()
.Name("docworkflow")
.Columns(columns =>
{
columns.Bound(e => e.ActionName);
columns.Bound(e => e.ActionType);
}).DataSource( **How do I load a script variable here***)
//This script variable should be fed to the above code.
This variable is populatedwhen the user adds data from the UI which works fine.
var dataSource = new kendo.data.DataSource({
data: result,
schema: {
model: {
fields: {
ActionName: { type: "string" },
ActionType: { type: "string" }
}
}
},
pageSize: 20
});
A user can change the language manually from the website. But for better user experience, I would like to change it automatically based on the users' browser language. I have a global Controller and can use init() and then redirect.
Please give me tips to do it right.
You should remember the chosen language for a user, if they had selected one previously, I store this in the database, in a user_preference table.
Then you need to intercept the request, it can be done in the application configuration file, using the on beforeRequest property.
If you don't have stored a preference for the current user, or the user is a guest, use the browser language to set the application language.
Configuration file
use app\models\User;
...
'on beforeRequest' => function ($event) {
$user_lang = '';
if (!Yii::$app->user->isGuest) {
// Check if you have stored a language preference for the user
$user_lang = User::findIdentity(Yii::$app->user->id)->getUserPreference('lang');
}
if (!empty($user_lang)) {
// If you have a stored preference for the user, use it
Yii::$app->language = $user_lang;
} else {
// If you don't have a preference, use the browser language
// Get the browser language from the headers
$browser_lang = Yii::$app->request->headers->get('accept-language');
// Alternatively get the headers from the event
// $event->sender->request->headers->get('accept-language')
// Calculate the language you want to provide based on the browser language
$language_code = LanguageHelper::calculatei18nCode($browser_lang);
Yii::$app->language = $language_code;
}
},
...
If you wanted to keep your configuration file clean, you could use filters instead to intercept the request.
Your LanguageHelper::calculatei18nCode($browser_lang) method would try to find a match for the browser language in the available languages, if it didn't find one it could return the closest match, or the default application language.
LanguageHelper
public static function calculatei18nCode ($browser_lang) {
// For example, if you are offering one translation file for french
if (stripos($browser_lang, 'fr')) {
return 'fr';
}
...
return 'en';
}
I`m trying to insert a custom link to a special page in VisualEditor toolbar. See the image below.
See Image
I googled a lot but without success. Someone please give a path...
My answer is based on the following resources:
MediaWiki core JS doc (ooui-js)
VisualEditor JS doc (+ reading code of both repositories used for VE, mediawiki/extension/VisualEditor and VisualEditor)
Also, I'm pretty sure, that there is no documented way of adding a tool to the toolbar in VE, as far as I know. Although it's possible to add a tool to a group, which is already added, mostly used for the "Insert" tool group, like in Syntaxhighlight_GeSHi). There is, probably, a much easier or "better" way of doing this :)
First, VisualEditor provides a way to load additional modules (called plugins) when the main part of VE loads (mostly, when you click the "Edit" button). The modules needs to be registered via the global variable $wgVisualEditorPluginModules (or the equivalent in extension.json, if you're using the new extension registration). In your extension registration file, you should initialize a module (with your required script files to add the tool) and add it as a VE plugin.
Example PHP (old extension registration via PHP files):
// other setup...
$wgResourceModules['ext.extName.visualeditor'] = array(
'localBasePath' => __DIR__,
'remoteExtPath' => 'extName'
'dependencies' => array(
'ext.visualEditor.mwcore',
),
'scripts' => array(
'javascripts/ve.ui.ExtNameTool.js',
),
'messages' => array(
'extname-ve-toolname',
),
);
$wgVisualEditorPluginModules[] = 'ext.extName.visualeditor';
// other setup...
extension.json (new JSON-based extension registration):
// other setup...
"ResourceModules": {
"ext.geshi.visualEditor": {
"scripts": [
"javascripts/ve.ui.ExtNameTool.js"
],
"dependencies": [
"ext.visualEditor.mwcore"
],
"messages": [
"extname-ve-toolname"
]
}
},
"VisualEditorPluginModules": [
"ext.extName.visualeditor"
],
// other setup...
Now, if VE starts, it will load your module, named ext.extName.visualeditor in this example, with the script ve.ui.ExtNameTool.js. In this script, you can now do, what ever you want. As an example, this is a way to add a new module to the end of the toolgroup list in the toolbar:
Example of ve.ui.ExtNameTool.js:
( function () {
// create a new class, which will inherit ve.ui.Tool,
// which represents one tool
ve.ui.extNameTool = function extNameTool( toolGroup, config ) {
// parent constructor
ve.ui.extNameTool.super.apply( this, arguments );
// the tool should be enabled by default, enable it
this.setDisabled( false );
}
// inherit ve.ui.Tool
OO.inheritClass( ve.ui.extNameTool, ve.ui.Tool );
// every tool needs at least a name, or an icon
// (with the static property icon)
ve.ui.extNameTool.static.name = 'extname';
// don't add the tool to a named group automatically
ve.ui.extNameTool.static.autoAddToGroup = false;
// prevent this tool to be added to a catch-all group (*),
although this tool isn't added to a group
ve.ui.extNameTool.static.autoAddToCatchall = false;
// the title of the group (it's a message key,
// which should be added to the extensions i18n
// en.json file to be translateable)
// can be a string, too
ve.ui.extNameTool.static.title =
OO.ui.deferMsg( 'extname-ve-toolname' );
// onSelect is the handler for a click on the tool
ve.ui.extNameTool.prototype.onSelect = function () {
// show an alert box only, but you can do anything
alert( 'Hello' );
this.setActive( false );
}
// needs to be overwritten, but does nothing so far
ve.ui.extNameTool.prototype.onUpdateState = function () {
ve.ui.extNameTool.super.prototype.onUpdateState.apply( this, arguments );
}
// the tool needs to be registered to the toolFactory
// of the toolbar to be reachable with the given name
ve.ui.toolFactory.register( ve.ui.extNameTool );
// add this tool to the toolbar
ve.init.mw.Target.static.toolbarGroups.push( {
// this will create a new toolgroup with the tools
// named in this include directive. The naem is the name given
// in the static property of the tool
include: [ 'extname' ]
} );
} )();
After installing the extension in your LocalSettings.php and starting VE, you should see a new tool in the toolbar with the given name. Clicking it will show an alert box with content "Hello". Like written in the inline comments: In the click handler (onSelect) you can do whatever you want, e.g. open a link in a new tab, e.g. to a Special page. To get the link to a special page I would suggest to use mw.Title to get a localized namespace. For example:
var relativeUrl = mw.Title.newFromText( 'RecentChanges', -1 ).getUrl();
The first parameter of mw.Title.newFromText() is the name of the page, the second parameter is the ID of the namespace (-1 is the default for special pages and should always work).
I hope that helps!
I am not sure I understand your question entirely. It is as simple as selecting some text, clicking the chain icon, then clicking the External Link tab and pasting your link there.
I am not sure what the proper heading / title for this question should be. I am new to WinJS and am coming from a .NET webform and winclient background.
Here is my scenario. I have a navigation WinJS application. My structure is:
default.html
(navigation controller)
(settings flyout)
pages/Home.html
pages/Page2.html
So at the top of the default.js file, it sets the following variables:
var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;
var nav = WinJS.Navigation;
It seems like I cannot use these variables anywhere inside my settings flyout or any of my pages:ready functions. They are only scoped to the default.js?
In the same regard, are there resources on the interwebs (links) that show how to properly share variables, events, and data between each of my "pages"?
The scenario that I immediately need to overcome is settings. In my settings flyout, I read and allow the user to optionally set the following application setting:
var applicationData = Windows.Storage.ApplicationData.current;
var localSettings = applicationData.localSettings;
localSettings.values["appLocation"] = {string set by the user};
I want to respond to that event in either my default.js file or even one of my navigation pages but I don't know where to "listen". My gut is to listen for the afterhide event but how do I scope that back to the page where I want to listen from?
Bryan. codefoster here. If you move the lines you mentioned...
var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;
var nav = WinJS.Navigation;
...up and out of the immediate function, they'll be in global scope and you'll have access to them everywhere. That's one of the first things I do in my apps. You'll hear warnings about using global scope, but what people are trying to avoid is the pattern of dropping everything in global scope. As long as you control what you put in there, you're fine.
So put them before the beginning of the immediate function on default.js...
//stuff here is scoped globally
var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;
var nav = WinJS.Navigation;
(function () {
//stuff here is scoped to this file only
})();
If you are saving some data and only need it in memory, you can just hang it off the app variable instead of saving it into local storage. That will make it available to the whole app.
//on Page2.js
app.myCustomVariable = "some value";
//on Page3.js
if(app.myCustomVariable == "some value") ...
Regarding your immediate need:
like mentioned in the other answer, you can use datachanged event.
Regards sharing variables:
If there are variables that you would like to keep global to the application, they can be placed outside the anonymous function like mentioned in the Jeremy answer. Typically, that is done in default.js. Need to ensure that scripts using the global variables are placed after the script defining the global variable - in default.html. Typically - such variable will point to singleton class. For example: I use it in one of my apps to store authclient/serviceclient for the backend service for the app. That way - the view models of the multiple pages need not create instance of the object or reference it under WinJS namespace.
WinJS has also concept of Namespace which lets you organize your functions and classes. Example:
WinJS.Namespace.define('Utils.Http',
{
stringifyParameters: function stringifyParameters(parameters)
{
var result = '';
for (var parameterName in parameters)
{
result += encodeURIComponent(parameterName) + '=' + encodeURIComponent(parameters[parameterName]) + '&';
}
if (result.length > 0)
{
result = result.substr(0, result.length - 1);
}
return result;
},
}
When navigating to a page using WinJS.Navigation.navigate, second argument initialState is available as options parameter to the ready event handler for the page. This would be recommended way to pass arguments to the page unless this it is application data or session state. Application data/session state needs to be handled separately and needs a separate discussion on its own. Application navigation history is persisted by the winjs library; it ensures that if the app is launched again after suspension - options will be passed again to the page when navigated. It is good to keep the properties in options object as simple primitive types.
Regards events:
Typically, apps consume events from winjs library. That can be done by registering the event handler using addEventListener or setting event properties like onclick etc. on the element. Event handlers are typically registered in the ready event handler for the page.
If you are writing your own custom control or sometimes in your view model, you may have to expose custom events. Winjs.UI.DOMEventMixin, WinJS.Utilities.createEventProperties can be mixed with your class using WinJS.Class.mix. Example:
WinJS.Class.mix(MyViewModel,
WinJS.Utilities.createEventProperties('customEvent'),
WinJS.UI.DOMEventMixin);
Most often used is binding to make your view model - observable. Refer the respective samples and api documentation for details. Example:
WinJS.Class.mix(MyViewModel,
WinJS.Binding.mixin,
WinJS.Binding.expandProperties({ items: '' }));
Here is what I ended up doing which is kinda of a combination of all the answers given:
Created a ViewModel.Settings.js file:
(function () {
"use strict";
WinJS.Namespace.define("ViewModel", {
Setting: WinJS.Binding.as({
Name: '',
Value: ''
}),
SettingsList: new WinJS.Binding.List(),
});
})();
Added that file to my default.html (navigation container page)
<script src="/js/VMs/ViewModel.Settings.js"></script>
Add the following to set the defaults and start 'listening' for changes
//add some fake settings (defaults on app load)
ViewModel.SettingsList.push({
Name: "favorite-color",
Value: "red"
});
// listen for events
var vm = ViewModel.SettingsList;
vm.oniteminserted = function (e) {
console.log("item added");
}
vm.onitemmutated = function (e) {
console.log("item mutated");
}
vm.onitemchanged = function (e) {
console.log("item changed");
}
vm.onitemremoved = function (e) {
console.log("item removed");
}
Then, within my application (pages) or my settings page, I can cause the settings events to be fired:
// thie fires the oniteminserted
ViewModel.SettingsList.push({
Name: "favorite-sport",
Value: "Baseball"
});
// this fires the itemmutated event
ViewModel.SettingsList.getAt(0).Value = "yellow";
ViewModel.SettingsList.notifyMutated(0);
// this fires the itemchanged event
ViewModel.SettingsList.setAt(0, {
Name: "favorite-color",
Value: "blue"
});
// this fires the itemremoved event
ViewModel.SettingsList.pop(); // removes the last item
When you change data that needs to be updated in real time, call applicationData.signalDataChanged(). Then in the places that care about getting change notifications, listen to the datachanged on the applicationData object. This is also the event that is raised when roaming settings are synchronized between computers.
I've found that many times, an instant notification (raised event) is unnecessary, though. I just query the setting again when the value is needed (in ready for example).
