The document discusses Visualforce, a framework for building component-based applications and pages for Salesforce. It provides an overview of Visualforce tags and capabilities like interacting with Apex controllers, calling remote actions via JavaScript, and using the REST API. It also briefly introduces Remote Objects, a new feature in Spring '14 that allows CRUD operations without Apex code.

4. Visualforce

5. Framework
 Server-side compiled web pages
– (Think PHP, JSP, etc.)
 Easily create salesforce UI
 Standard-compliant
 Can Interact With Apex for Custom Logic

6. Device Access Through Web APIs
 Audio/Video Capture
 Geolocation
 Accelerometer

7. Visualforce Tags
<apex:page docType=“html-5.0” />
<apex:input type=“email”/>
<apex:pageBlockSection collapsible=“false” />

8. Styling for Visualforce in S1
 Salesforce1 Styleguide
sfdc-styleguide.herokuapp.com/
 OneStarter jQuery plugin
github.com/joshbirk/onestarter

9. Hashed information block to track server side transports
Viewstate

10. Apex Form
 Required for standard salesforce post
 Incurs Viewstate Overhead
<apex:form>
…
</apex:form

ilbodfubqo3e8ufbw

11. Interacting with the Platform
 Apex Controller Instance Method
 Apex Controller Static Remoting Method
 REST API
 Visualforce Remote Object

12. Apex Instance Method
 Use with apex:actionFunction to access via
Javascript
 ActionFunction requires ViewState
 Reduce ViewState with Transient and Static

13. Apex Remote Action
 Static
 No View State
 Invoked through JS API
 Invokes JS Callback
@remoteAction
global static String myMethod(String
inputParam){
...
}

14. Calling Apex Remote Action
Visualforce.remoting.Manager.invokeAction(’
{!$RemoteAction.RemoteClass.methodName}'
,
param,
function(result, event) {
//...callback to handle result
});

15. Event Object: Success Example
{
"statusCode":200,
"type":"rpc",
"ref":false,
"action":"IncidentReport",
"method":"createIncidentReport",
"result":"a072000000pt1ZLAAY",
"status":true
}

16. Event Object: Failure Example
{
"statusCode":400,
"type":"exception",
"action":"IncidentReport",
"method":"createIncidentReport",
"message":"List has more than 1 row for assignment to SObject",
"data": {"0":
{"Merchandise__c":"a052000000GUgYgAAL","Type__c":"Accident","Desc
ription__c":"This is an accident report"}},
"result":null,
"status":false
}

17. Interacting with the Publisher: Allow Submit
 Make Submit Active
 Payload true/false
Sfdc.canvas.publisher.publish(
{
name:
"publisher.setValidForSubmit", payload:true
});

18. Interacting with the Publisher: Subscribe to Submit
 Attach to Submit Event
Sfdc.canvas.publisher.subscribe({
name: "publisher.post",
onData:function(e) {
// This subscribe fires when the user hits 'Submit'
in the publisher
postToFeed();
}});

19. Interacting with the Publisher: Close Publisher
 Make the Submit Happen
Sfdc.canvas.publisher.publish({name:
"publisher.close", payload:
{ refresh:"true"}});

20. REST API
 For large data transactions
 Use forcetk library for easy access.
github.com/developerforce/Force.com-JavaScript-REST-
Toolkit

21. forcetk: Init and Bind To Session
<apex:includeScript value="{!$Resource.forcetk}"/>
...
var restClient = new forcetk.Client();
var contentId;
var merchId;
restClient.setSessionToken('{!$Api.Session_ID}');
//turn off proxy now that we have session
restClient.proxyUrl = null;
restClient.instanceUrl = '';

22. forcetk: Init and Bind To Session
restClient.create('ContentVersion', {
"Origin": "H",
"PathOnClient": file.name,
"VersionData": imageData
}, function(data) {
...
$('#test-display').text('File Create Complete:' + data.id);
...
}, onErrorSfdc);

23. Spring ’14
(Developer Preview)

24. Remote Objects
 Standard CRUD/Q functionality without Apex
 Similar to remoteTK or SObjectData
 Visualforce components define data models
<apex:jsSObjectBase shortcut="tickets">
<apex:jsSObjectModel name="Ticket__c" />
<apex:jsSObjectModel name="Contact" fields="Email" />
<script>
var contact = new tickets.Contact();
contact.retrieve({
where: {
Email: {
like: query + '%'
}
}
}, function(err, data) {
