apex:actionFunction – Salesforce.com

There are times when we have to update components based on events on other parts of visualforce pages.
So below is the code that can be used for reference.
You can use below code for reference here we are updating a checkbox based on
change in account source.
<apex:page extensions=”testComponent” id=”thepage” standardcontroller=”Account”>
<apex:form>
<apex:inputfield value=”{!acc.AccountSource}”>
<apex:actionsupport action=”{!changeCheckBox}” event=”onchange” rerender=”pan” status=”counterStatus”>
</apex:actionsupport></apex:inputfield>
<apex:outputpanel id=”pan”>
<apex:inputfield id=”test” value=”{!acc.check__c}”>
</apex:inputfield></apex:outputpanel>
<apex:actionstatus id=”counterStatus” starttext=” (incrementing…)” stoptext=” (done)”>
</apex:actionstatus></apex:form>
</apex:page>
public with sharing class testComponent {
public testComponent() {
}
public Account acc{get;set;}
public testComponent(ApexPages.StandardController controller) {
acc=[select id,AccountSource,check__c from account where id=’0019000000CJ6QZ’];
}
public pagereference changeCheckBox(){
acc.check__c=true;
return null;
}
}

Salesforce.com: Expression Operators in Salesforce lightning Components

Image
Generally In every component implementation we have a need to  change the UI conditionally, or show/hide a section/column based on certain conditions. We need simple ways to do this instead of having every handler in code. Below are key operators and their syntax to handle any such situation Ternary Operator This expression uses the ternary operator to conditionally output one of two values dependent on a condition. 1 <a class="{!v.location == '/active' ? 'selected' : ''}" href="#/active">Active</a> The {!v.location == ‘/active’ ? ‘selected’ : ”} expression conditionally sets the class attribute of an HTML <a> tag, by checking whether the location attribute is set to /active . If true, the expression sets class to selected . Using <aura:if> for Conditional Markup <aura:attribute name="edit" type="Boolean" default="true"/> <aura:if isTrue=...

Salesforce.com: Scheduled Apex

The Apex Scheduler lets you delay execution so that you can run Apex classes at a specified time. This is ideal for daily or weekly maintenance tasks using Batch Apex. To take advantage of the scheduler, write an Apex class that implements the Schedulable interface, and then schedule it for execution on a specific schedule. Scheduled Apex Syntax To invoke Apex classes to run at specific times, first implement the Schedulable interface for the class. Then, schedule an instance of the class to run at a specific time using the System.schedule method. global class SomeClass implements Schedulable { global void execute(SchedulableContext ctx) { // awesome code here } } The class implements the Schedulable interface and must implement the only method that this interface contains, which is the execute method. The parameter of this method is a SchedulableContext object. After a class has been scheduled, a CronTrigger object is created that represents the scheduled job. It p...
