Salesforce Lightning: Countdown timer
Today we will have a look at how to create a lightning component for countdown timer which can be used on pages where an operation needs to be completed within a specific time period. Example, an online exam or a banking transaction which expires after a specific time period. The component contains a datetime field which represents the end time. Once the user selects the date and time and clicks on Start Timer button, the countdown timer will start. Below is the lightning component: CountdownTimer.cmp <aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId" access="global" > <aura:attribute name="endTime" type="String"/> <aura:attribute name="timeLeft" type="String"/> <lightning:tile label="Time Left" class="slds-page-header"> {!v.timeLeft} </lightning:tile>
