Interacting with the Platform

Apex Controller Instance Method

Apex Controller Static Remoting Method

REST API

Visualforce Remote Object

Apex Instance Method

Use with apex:actionFunction to access via Javascript

ActionFunction requires ViewState

Reduce ViewState with Transient and Static

Apex Remote Action

Static

No View State

Invoked through JS API

Invokes JS Callback

@remoteAction

global static String myMethod(String

inputParam){

...

}

Calling Apex Remote Action

Visualforce.remoting.Manager.invokeAction(’

{!

$RemoteAction.RemoteClass.methodName}',

param,

function(result, event) {

//...callback to handle result

});

Event Object: Success Example

{

"statusCode":200,

"type":"rpc",

"ref":false,

"action":"IncidentReport",

"method":"createIncidentReport",

"result":"a072000000pt1ZLAAY",

"status":true

}

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

}

Interacting with the Publisher: Allow Submit

Make Submit Active

Payload true/false

Sfdc.canvas.publisher.publish(

{

name: "publisher.setValidForSubmit",

payload:true

});

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();

}});

Interacting with the Publisher: Close Publisher

Make the Submit Happen

Sfdc.canvas.publisher.publish({name:

"publisher.close", payload:

{ refresh:"true"}});

REST API

For large data transactions

Use forcetk library for easy access.

github.com/developerforce/Force.com-JavaScript-REST-Toolkit

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 = '';

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);

Spring ’14(Developer Preview)

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) {
