Lightning Table With Multiple Checkbox Select Options

Here is an example of Lightning Contact List data table with multiple checkbox select option.

Apex Controller:

public class ContactAuraController {
    
    @AuraEnabled
    Public static List<Contact> getContactList(){
        //get all contact list
        List<Contact> conList = [SELECT Id, Name, Account.Name, Phone, Email FROM Contact LIMIT 10];
        return conList;
    }
}

Component:

<!--

    <aura:handler name="init" action="{!c.doInit}" value="{!this}"/>

USA Standard Telephone Formatting in Lightning Experience

I had a requirement to automate a Phone number field to USA standard format. As of now in Lightning there is no such feature exists.

Here is an example:
Phone: 9831078379
USA Standard Format: (983) 107-8379

Component:

<aura:component>
    <div class="slds-m-around_xx-large">
        <lightning:input type="text" maxlength="10" onblur = "{!c.formatPhoneNumber}" aura:id="Phone" label="Phone" name="Phone"/>
    </div>
</aura:component>

JS Controller:

({
    formatPhoneNumber: function(component, helper, event) {
        var phoneNo = component.find("Phone");
        var phoneNumber = phoneNo.get('v.value');
        var s = (""+phoneNumber).replace(/\D/g, '');
        var m = s.match(/^(\d{3})(\d{3})(\d{4})$/);
        var formattedPhone = (!m) ? null : "(" + m[1] + ") " + m[2] + "-" + m[3];
        phoneNo.set('v.value',formattedPhone);
    }
})

Output:

Bound and Unbound Expressions in Lightning Components

When we work with components, the first thing we do is declaring the attributes and initialize them. We use expressions for initializing our components. There are two types of expressions, bound and unbound that are used to perform data binding in Lightning Components.

Bound Expression: Bound Expression is represented as {!v.str}. Whenever the value of the string is changed, this expression will reflect the change and also affect the components where it is used, we can say the value change dynamically through this expression.

Unbound Expression: Unbound Expression is represented as {#v.str}. Whenever the value of the string is changed, this expression will not reflect the change, we can say the value remains static through this expression.

Here is an example of lightning component with Bound and Unbound Expressions:

Sample Component:

<aura:component>
    <aura:attribute name="str" type="string" default="Hello World!"/>
    <ui:outputText value="Enter a string value : "/>
    <ui:inputText value="{!v.str}"/>
    <br/>
    <ui:outputText value="Unboud Expression : "/>
    <ui:outputText value="{#v.str}"/>
    <br/>
    <ui:outputText value="Bound Expression : "/>
    <ui:outputText value="{!v.str}"/>
</aura:component>

Output:
bound-and-unbound-expressions

The value in bound expression variable changes on change of the input, but the value of unbound expression remains the same.
