Using JavaScript in
Visualforce Pages

14.
Why Use JavaScript?
• Build Engaging User Experiences
• Leverage JavaScript Libraries
• Build Custom Applications

15.
JavaScript in Visualforce Pages
Visualforce Page
JavaScript Remoting
Remote Objects
(REST)

16.
Demo Examples

17.
JavaScript Remoting
• Asynchronous page responses
• Most responsive and fastest way to grab data and perform DML
• All static data
• Decouples the page from the controller
• Lets you perform tasks on the page without reloading the entire page
• Can help alleviate View State issues
• Code still executes in the context of the user viewing the page
3 Parts:
1. In Apex Class: static @RemoteAction in Apex
2. On Visualforce Page: calls Remote Action in JavaScript
3. On Visualforce Page: response handler for result in JavaScript

18.
JavaScript Remoting - Server-Side
global with sharing class HotelRemoter {
@RemoteAction
global static List<Hotel__c> findAll() {
return [SELECT Id,
Name,
Location__Latitude__s,
Location__Longitude__s
FROM Hotel__c];
}
}

19.
"global with sharing"?
• global
– Available from outside of the application
• with sharing
– Run code with current user permissions. (Apex code runs in system context by default -- with
access to all objects and fields)

20.
JavaScript Remoting - Visualforce Page
<script>
Visualforce.remoting.Manager.invokeAction(
'{!$RemoteAction.HotelRemoter.findAll}',
function (result, event) {
if (event.status) {
for (var i = 0; i < result.length; i++) {
var lat = result[i].Location__Latitude__s;
var lng = result[i].Location__Longitude__s;
addMarker(lat, lng);
}
} else {
alert(event.message);
}
}
);
</script>

21.
Using JavaScript and CSS Libraries
• Hosted elsewhere
<script src="https://maps.googleapis.com/maps/api/js"></script>
• Hosted in Salesforce
– Upload individual file or Zip file as Static Resource
– Reference asset using special tags
– Covered in Static Resources Exercise later

22.
Lab 3: Using JavaScript in Visualforce Pages
• Write the HotelMap Visualforce Page

23.
Using the REST APIs

24.
When?
Get access to Salesforce data from outside Salesforce:
• Integrate Salesforce in existing apps
• Build consumer apps
• Device integration (Internet of Things)

25.
Mobile SDK Example
OAuth
REST APIs

26.
Browser Cross-Origin Restrictions
OAuth
REST APIs
app.js
index.html
HTTP Server
Cross Origin Policy

27.
Using a Proxy
OAuth
REST APIs

30.
Connected App

31.
Salesforce REST Toolkit
https://github.com/developerforce/Force.com-JavaScript-REST-Toolkit

32.
Lab 10: Using the REST APIs
• Create a consumer app hosted outside Salesforce

33.
Windows Users
After installing Node.js:
1. Add c:Program FilesNodejs to your path
or
Run "C:Program FilesNodejsnpm" install
2. Create an "npm" directory in
C:Users[yourname]AppdataRoaming

34.
Using Static Resources

35.
What are Static Resources?
• Files uploaded to Salesforce instance for use in Visualforce pages
– .js
– .css
– .jpg, .png, .gif, etc.
• Can be uploaded individually or as archive (.zip or .jar)

36.
Static Resources

37.
Visualforce and HTML Page Generation
• By default, Visualforce generates HTML page elements:
– <html>
– <head>
– <body>
• <apex:> tags ensure corresponding HTML elements are inserted at the right place
– <apex:stylesheet>
– <apex:includeScript>

38.
Referencing Static Resources
// Single file
<apex:stylesheet value="{!$Resource.bootstrap}"/>
<apex:includeScript value="{!$Resource.jquery}"/>
<apex:image url="{!$Resource.logo}"/>
// ZIP file
<apex:stylesheet value="{!URLFOR($Resource.assets, 'css/main.css')}"/>
<apex:image url="{!URLFOR($Resource.assets, 'img/logo.png')}"/>
<apex:includeScript value="{!URLFOR($Resource.assets, 'js/app.js')}"/>

39.
Controlling HTML Page Generation
• You can also take full control over HTML elements generation and position:
<apex:page docType="html-5.0” applyHtmlTag="false” applyBodyTag="false">
• Add arbitrary components to Visualforce components that will be “passed through” to
rendered HTML
• prefix the attribute with "html-”
• used to improve usability with HTML5 features such as placeholder “ghost” text,
pattern client-side validation, and title help text attributes.
• … and use standard HTML tags
• <link rel="stylesheet" href="…">
• <script src="…">

40.
Referencing Static Resources
// Single file
<link href="{!$Resource.bootstrap}" rel="stylesheet"/>
<img src="{!$Resource.logo}"/>
<script src="{!$Resource.jquery}"></script>
// ZIP file
<link href="{!URLFOR($Resource.assets, 'css/main.css')}" rel="stylesheet"/>
<img src="{!URLFOR($Resource.assets, 'img/logo.png')}"/>
<script src="{!URLFOR($Resource.assets, 'js/app.js')}"></script>

41.
Lab 11: Static Resources
• Host single page application in Visualforce page

42.
Using Canvas
Applications

43.
What is a Canvas App?
• A web app integrated in your Salesforce environment
• Can be written in any language
– Java, .NET, PHP, Ruby on Rails, Node.js, etc.
• Transparently authenticated
• Context aware (logged in user, current object, etc.)

44.
Use Cases
• Internal App
• Third-Party / Partner App
• External systems with web facade

45.
Where Can It Be Integrated?
• Publisher
• Page Layouts
• Visualforce Pages
• Tabs
• Mobile Cards

46.
Defining a Canvas App

47.
Transparent Authentication
• When loading Canvas app, Salesforce instance posts Base64 encoded data to app
endpoint including:
– Authenticated token
– Context (logged in user, current object, etc)
• App decodes data using client secret
• Can use authenticated token to make REST API calls

48.
Node.js example
var decode = require('salesforce-signed-request');
var secret = process.env.CONSUMER_SECRET;
app.post('/signedrequest', function(req, res) {
var signedRequest = req.body.signed_request;
var decodedRequest = decode(signedRequest, secret);
var oauthToken = decodedRequest.client.oauthToken;
var instanceUrl = decodedRequest.client.instanceUrl;
var context = decodedRequest.context;
});

49.
Lab 12: Canvas
• Deploy Node.js web app to Heroku
• Integrate app in Contact page layout

50.
Writing Unit Tests

51.
Unit Testing
• Code to test code
• Increases quality and predictability
• Unit test coverage is required to move code to production
– Must have at least 75% of code covered
– Coverage = lines of code exercised by tests / total line of code

52.
Anatomy of a Test Class
@isTest
private class myClass {
static testMethod void myTest() {
// 1. Prepare temporary data
// 2. Start Test
// 3. Execute some code
// 4. Stop Test
// 5. Assert
}
}

53.
Create Temporary Data
Datetime now = System.now();
// Create speaker
Speaker__c sp = new Speaker__c(First_Name__c='Al', Last_Name__c='Smith');
insert sp;
// Create two sessions starting at the same time
Session__c s1 = new Session__c(Name='Session1', Session_Date__c=now);
insert s1;
Session__c s2 = new Session__c(Name='Session2', Session_Date__c=now);
insert s2;
// Book speaker for session1
Session_Speaker__c booking1 = new Session_Speaker__c(Session__c=s1.Id, Speaker__c=sp.Id);
insert booking1;

54.
Test and Assert
Test.startTest();
// Try to book speaker for session2
Session_Speaker__c booking2=
new Session_Speaker__c(Session__c=s2.Id, Speaker__c=sp.Id);
Database.SaveResult result = Database.insert(booking2, false);
Test.stopTest();
// Insert should fail: can't book same speaker for 2 sessions happening
// at same time
System.assert(!result.isSuccess());

55.
Running Tests

56.
Lab 13: Unit Testing
• Write the TestDoubleBooking class
• Run the test

57.
Batch and Schedule

58.
What's a Batch?
• Long-running process that runs without manual intervention
• Started programmatically

59.
Defining a Batch Job
global class SendReminderEmail implements Database.Batchable {
global SendReminderEmail(String query, String subject, String body) {
// Constructor: accept parameters
}
global Database.QueryLocator start(Database.BatchableContext bc) {
// Select scope (records to process)
}
global void execute(Database.BatchableContext bc, List<Speaker__c> scope) {
// Process data
}
global void finish(Database.BatchableContext bc) {
// Post processing operations
}
}

60.
Running the Batch Job
String q = 'SELECT First_Name__c, Last_Name__c, Email__c ' +
'FROM Speaker__c WHERE Email__c != null';
SendReminderEmail batch = new SendReminderEmail(q,
'Final Reminder', 'The conference starts next Monday');
Database.executeBatch(batch);

61.
What's Scheduled Job?
• Unattended background program execution
• Occurs at a specified time
• Optionally repeated at a specified interval

62.
Defining a Scheduled Job
global class ScheduledEmail implements Schedulable {
global void execute(SchedulableContext sc) {
String q = 'SELECT First_Name__c, Last_Name__c, Email__c ' +'FROM Speaker__c
WHERE Email__c != null';
SendReminderEmail batch = new SendReminderEmail(q,
'Final Reminder', 'The conference starts next Monday');
Database.executeBatch(batch);
}
}

63.
Scheduling the Job (using Code)
ScheduledEmail job = new ScheduledEmail();
// Run at 8AM on February 10th
// (Seconds Minutes Hours Day_of_month Month Day_of_week Years)
// Can use wildcards
String schedule = '0 0 8 10 2 ?';
String jobId = System.schedule('Final reminder', schedule, job);

64.
Scheduling the Job (using Clicks)

65.
Monitoring Scheduled Jobs

66.
Lab 14: Batching and Scheduling
• Write the SendReminderEmail class
• Run the batch
