How to get selected record Id from apex:inputField in javascript

Question

I have a apex:inputField where I'm getting lookup field. Now I want to get the Id of that selected record in lookup field in my javascript.

I'm able to get the record name but not record id

VF Page:

 <apex:inputField id="accountName" value="{!Oppty.AccountId}" onchange="accountSelected(this.value);" />

function accountSelected(data){
        console.log(' >>> Account changed... '+JSON.stringify(data));
    }

To get the Id of the selected record in your JavaScript function, you can try modifying the accountSelected function to below.

It is named the same as the lookup field's (visible) textbox and is suffixed with _lkid.

function accountSelected(data) {
    var selectedAccountId =document.getElementById('{!$Component.accountName}_lkid').value;
    console.log(' >>> Account Id changed... ' + selectedAccountId);
}
