Magento 2 - Get the postcode entered in the Estimate Shipping block

Question

I'm trying to get the postcode that has been entered in the Estimate Shipping block on the basket page. I am trying to grab it from local storage. I have the following code on a template file that is called on the homepage:

<script>
    require(['jquery','Magento_Checkout/js/model/quote'], function($,quote){
        console.log(quote.shippingAddress().postcode)
    })
</script>

This one returns an error in the console: quote.shippingAddress(...) is null

I have also tried to retrieve it via the cart session:

...
use Magento\Checkout\Model\Cart;
...

public function __construct(
    Cart $cart,) {
    $this->cart = $cart;
}

public function getCustomerDeliveryPostcode() {
    $quote = $this->cart->getQuote();
    $shippingAddress = $quote->getShippingAddress();
    $postcode = $shippingAddress->getPostcode();
}

This one returns nothing. Can anyone see what is wrong? Magento 2.3.0

Answer 1

Try below code

protected $cartSess;

public function __construct(
\Magento\Checkout\Model\Session $cartSess
)
{
   $this->cartSess=$cartSess;
}

public function getPostcode()
{
    $quote =$this->cartSess->getQuote();
    foreach ($quote->getAllAddresses() as $address) {
       $postcode = $address->getPostCode();
    }

    return $postcode;

}

I hope it will help...!!!
