6 Fundamental JavaScript 

7 Fundamentals Concepts of JavaScript üEvent-driven, asynchronous programming üInteract with HTML and CSS üOther common programming features • Data processing • API • Browser API: DOM, Geolocation, Canvas & WebGL, WebRTC, etc. • 3rd Party API: Google Maps, OpenStreetMap, etc. https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps/What_is_JavaScript https://developer.mozilla.org/en-US/docs/Learn/Getting_started_with_the_web/JavaScript_basics 

8 Event-driven, Asynchronous Coding • The DOM is loaded • A user clicks an element or scrolls the page • A user types keyboard • Asynchronous request that finishes fetching There are a lot of different type of events. You can respond to any event using an Event Handler/Listener, which is a function that’s called when an event occurs. https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener https://developer.mozilla.org/en-US/docs/Web/Events 

function changeHandler(event) { // When input value is changed ... console.log(event.target.value); } var input = document.getElementById('input'); input.addEventListener('change', changeHandler); 9 Define Event Handler/Listener #1 – addEventListener Change event example for text input Handler function HTML view Console Input texts are shown in the console when the value in input element is changed Handler function Event type Event attaching description Event target “Handler function is executed when Event type in Event target is triggered” 

var input = document.getElementById('input'); input.addEventListener('change', function(event) { // When input value is changed ... console.log(event.target.value); }); 10 Define Event Handler/Listener #2 – addEventListener Handler function can be described as a callback function with inline Change event example for text input HTML view Console Input texts are shown in the console when the value in input element is changed 

11 Define Event Handler/Listener #3 – Inline Event Handler function changeHandler(value) { // When input value is changed ... console.log(value); } HTML view Console Change event example for text input 

12 Define Event Handler/Listener #3 – DOM On-event Handler Load event example for window window.onload = function() { // When window is loaded... console.log('Window is open'); }; var xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.onload = function (success) { // When asynchronous request is succeeded... if (xhr.status === 200) { console.log(xhr.responseText); } }; xhr.onerror = function (error) { // When asynchronous request failed... console.log(error); }; Load/Error event example for XHR This style is a kind of shorthand notation of addEventListener.

15 Kintone JavaScript Events 

16 Conventional JavaScript Events vs Kintone Events Conventional JavaScript Kintone Event target ü Views ü Elements on HTML you build ü Views ü Record ü Field by Kintone built-in Event type ü Click ü Change ü Load etc. ü app.record.index.show ü app.record.change.text_field ü app.record.create.submit etc. Event description addEventListener() kintone.events.on() 

17 Kintone JavaScript Events https://kintone.dev/en/docs/kintone/js-api/ Triggered Timing Event Type 

18 Calculate and Set Age in Conventional JavaScript function calcAge(date) { date = date.split('-'); var year = Number(date[0]); var month = Number(date[1]); var day = Number(date[2]); var birthdate = year * 10000 + month * 100 + day; var today = new Date(); var targetdate = today.getFullYear() * 10000 + (today.getMonth() + 1) * 100 + today.getDate(); return (Math.floor((targetdate - birthdate) / 10000)); } document.getElementById('date').addEventListener('change', function (event) { // When input value is changed ... console.log(event.target.value); var date = event.target.value; var age = calcAge(date); document.getElementById('age').value = age; // Set age into input#age element }); 

function calcAge(date) { date = date.split('-'); var year = Number(date[0]); var month = Number(date[1]); var day = Number(date[2]); var birthdate = year * 10000 + month * 100 + day; var today = new Date(); var targetdate = today.getFullYear() * 10000 + (today.getMonth() + 1) * 100 + today.getDate(); return (Math.floor((targetdate - birthdate) / 10000)); } kintone.events.on('app.record.create.change.Birthdate', function(event) { // When Birthdate field is changed ... console.log(event); var date = event.record.Birthdate.value; var age = calcAge(date); event.record.Age.value = age; // Set age into Age field return event; // Don’t forget to return event object }); 19 Calculate and Set Age in Kintone 

20 Conventional JavaScript Event vs Kintone Event for Calculating Age Example document.getElementById('date').addEventListener('change', function (event) { // When input value is changed ... console.log(event); var date = event.target.value; var age = calcAge(date); document.getElementById('age').value = age; // Set age into input#age element }); kintone.events.on('app.record.create.change.Birthdate', function(event) { // When Birthdate field is changed ... console.log(event); var date = event.record.Birthdate.value; var age = calcAge(date); event.record.Age.value = age; // Set age into Age field return event; // Don’t forget to return event object }); Conventional JavaScript Kintone Handler function Event type Event attaching description Event target 

Define Kintone JavaScript Events kintone.events.on(type, handler); handler function should be written to return event object. function(event) { doSomeSyncProcessing(); return event; } What event object in Kintone can do ü Get/Update field values: event.record.field_code.value ü Enable/Disable fields: event.record.field_code.disabled ü Show error message on each field : event.record.field_code.error ü Show error message on record: event.error etc. Event object has general features as bellow although it has different properties according to event type event.record.Age.disabled = true; event.record.Details.error = 'Required when you discount.'; 21 

22 Define Kintone JavaScript Events kintone.events.on(type, handler); Synchronous Asynchronous for all events except change Asynchronous for change events function(event) { doSomeSyncProcessing(); return event; } function(event) { return somePromiseObject.then(function(response) { doSomeSyncProcessing(); return event; }).catch(function(error) { console.log(error); var message = 'Error Occurred'; event.error = event.error ? event.error + message : message; return event; }); } function(event) { somePromiseObject.then(function(response) { var record = kintone.app.record.get().record; doSomeSyncProcessing(); kintone.app.record.set({record: record}); }).catch(function(error) { console.log(error); var message = 'Error Occurred'; alert(message); }); return event; } 

23 Get/Set Data 

24 Get/Set Data • Get app ID: kintone.app.getId() • Get record ID: kintone.app.record.getId() • Get record values: kintone.app.record.get() • Set record values: kintone.app.record.set(recordObj) etc. https://kintone.dev/en/docs/kintone/js-api/ 

25 Get/Set Data – Example in Console To open Google Chrome DevTools Mac: Command + Option + I Win: Ctrl + Shift + I 

26 Kintone REST API Request from JavaScript 

27 Kintone REST API Request – Example in Kintone JavaScript Event https://kintone.dev/en/docs/kintone/js-api/other/kintone-rest-api-request/#kintone-rest-api-request kintone.api(pathOrUrl, method, params, opt_callback, opt_errback); Parameter Value Required Description pathOrUrl String Yes The path of the Kintone REST API, or the URL obtained with kintone.api.url. method String Yes The HTTP method. Specify one of the following: GET / POST / PUT / DELETE. params Object Yes The parameters to be used with the API, specified as an object. opt_callback Function Optional The callback function called when the API succeeds. opt_errback Function Optional The callback function called when the API fails. Request Parameters Response A kintone.Promise object will be returned if the callback parameter is ignored. Otherwise, there will be no response. 

28 Kintone REST API Request – Example in Kintone JavaScript Event kintone.events.on('app.record.index.show', function(event) { kintone.api(kintone.api.url('/k/v1/records', true), 'GET', { app: kintone.app.getId() }, function(response){ console.log(response); }, function(error){ console.log(error); }); return event; }); kintone.events.on('app.record.index.show', function(event) { return kintone.api(kintone.api.url('/k/v1/records', true), 'GET', { app: kintone.app.getId() }).then(function(response){ console.log(response); return event; }).catch(function(error){ console.log(error); return event; }); }); Asynchronous operation with simple callback Asynchronous operation with Promise https://kintone.dev/en/docs/kintone/js-api/other/kintone-rest-api-request/#kintone-rest-api-request 

Kintone REST API Request – Example in Console 

30 Quick Explanation - Promise 

31 Quick Explanation - Promise ü Promise object Ø This lets asynchronous methods return values like synchronous methods Ø This contains a fulfilled or rejected returning value Ø Promise is in one of these states Ø pending: initial state, neither fulfilled nor rejected Ø fulfilled: meaning that the operation completed successfully Ø rejected: meaning that the operation failed Ø Method chaining with .then() and .catch() Ø That is also called “Thenable object” ü How to create Promise object Ø new Promise() Ø Promise.resolve(), Promise.reject() Ø kintone.api(), kintone.proxy() [limited in Kintone] https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise new Promise(function(resolve, reject) { kintone.api(url, method, body, function(response) { // fulfilled returning value resolve(response); }, function(error) { // rejected returning value reject(error); } ); }); Equivalent kintone.Promise instead of native Promise in the browser cover IE11. kintone.Promise is the polyfill of Promise in Kintone. 

32 Quick Explanation - Promise ü How to retrieve a returning value https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise PromiseObject .then(function(fulfilledReturningValue) { // You can get and use a fulfilledReturningValue in this block #1 }) .catch(function(rejectedReturningValue) { // You can get and use a rejectedReturningValue in this block #2 }); after the PromiseObject operation is completed. When the operation contained in PromiseObject fulfilledReturningValue rejectedReturningValue succeeds fails , you can retrieve and use a in block #1 block #2 

33 Quick Explanation - Promise ü How to create the method chaining of Promise https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise PromiseObject1 .then(function(response1) { return PromiseObject2; }) .then(function(response2) { return PromiseObject3; }) .then(function(response3) { return PromiseObject4; }) ... .then(function(responseSecondToLast) { return PromiseObjectLast; }); Promise object chained with .then() becomes a new Promise object Totally this Promise object has a returning value from PromiseObjectLast when all chained Promise objects are fulfilled. 

PromiseObject1 .then(function(response1) { return PromiseObject2; }) .then(function(response2) { return PromiseObject3; }) .then(function(response3) { return PromiseObject4; }) ... .then(function(responseSecondToLast) { return PromiseObjectLast; }); 34 Quick Explanation - Promise https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise ü Points to be careful of Ø Prevent the chain from breaking Ø Don’t miss several patterns of return Promise object Function returning Promise object var promise = function() { return PromiseObject; }; var promise = function() { return PromiseObject1 .then(function(response1) { return PromiseObject2; }); }; 

35 Ref. 3 Patterns about The Retrieval of The Result Value from Object/Function // Synchronous operation var sum1 = function (v1, v2) { var result = v1 + v2; return result; }; // Asynchronous operation with simple callback var sum2 = function (v1, v2, callback) { var result = v1 + v2; return callback(result); }; // Asynchronous operation with Promise var sum3 = function (v1, v2) { var result = v1 + v2; return Promise.resolve(result); }; var result1 = sum1(1, 2); alert(result1); sum2(3, 4, function (result2) { alert(result2); }); sum3(5, 6).then(function (result3) { alert(result3); }); Definitions Retrievals 

36 Basic JavaScript structure in Kintone with ES5 

37 Write JavaScript with ES5 (function(){ 'use strict'; var handler = function(event) { console.log(event); return event; } kintone.events.on('app.record.index.show', handler); })(); IIFE (Immediately Invoked Function Expression) prevents polluting global scope https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode https://developer.mozilla.org/en-US/docs/Glossary/IIFE Strict mode eliminates some JavaScript silent errors, etc. You can write JavaScript here ü Declare variables ü Declare functions ü Define events https://kintone.dev/en/legal/javascript-coding-guidelines/ UTF-8 without BOM
