LIGHTNING AURA ATTRIBUTE

Aura attribute is the first thing you need to define in your salesforce lightning component.
Similar to the variable declaration with its data type, we will define a variable first and we will use that variable in further code.

So let's get started, we will use <aura:attribute/> tag to define aura attribute.

The example of the aura attribute is :

=================================================

<aura : attribute name="Num1" type="Integer"/>

=================================================

So as you can see in the above example aura attribute tag is defined as <aura:attribute>, Where name and type are required whenever you are defining aura attribute in salesforce.

Now to access this variable Num1 and display value hold by attribute we use {!v.Num1}, Where {!v.xxx} is used to get value hold by attribute.

So basically lightning aura attributes are used to display something on front-end in application or component and for the back-end, we will use a .js controller. 

Hence you can also define your aura attribute inside a lightning application.

For Example :

=============================================

<aura:application>

    <aura:attribute name="salesforcekid" type="String" default="World"/>

  <h1>

    Hello {!v.salesforcekid}!

  </h1>

</aura:application>

=============================================

Output :

=============================================

Hello World

=============================================

• Now something interesting and my favorite that is to display Button or Textbox on lightning component.
• So to display button we use <ui:button/> tag with a label and to provide the action after clicking of a button you need to call client side controller i.e. .js controller method.
• Don't worry because we are gonna cover that as well.
• Button press action is defined as press="{c.method}" to call a method from client-side controller.
• For Example :

=============================================

<aura:component>

  <aura:attribute name="name" type="String"/>

   <h1>

        Welcome to salesforce {!v.name}

     </h1>

      <ui:button label="Click Me" press="{!c.myname}"/>

   

</aura:component>

=============================================

• Above component will call myname method from .js controller and provide value to {!v.name}.
• We will see how to set a value into an attribute and display the result in the upcoming episodes of this series.
• So the output of the above aura component is like this :

=============================================

Welcome to salesforce kid

=============================================

In this way, you can create and use aura attribute in salesforce lightning
