### Access Stripe Instance in front-end JS

{% hint style="danger" %}
Make sure to fetch the form handlers after DOM is ready.
{% endhint %}

Let's say you want to get Stripe [payment element](https://docs.stripe.com/js/element/payment_element) in [Checkout Element Form](https://docs.payaddons.com/elements/checkout-element-form-pro): 

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.getElement('payment')
```

{% endcode %}

Let's say you want to get Stripe [card element](https://docs.stripe.com/js/elements_object/create_element?type=card) in [Checkout Credit Card Form](https://docs.payaddons.com/elements/checkout-credit-card-form-pro): 

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.getElement('card')
```

{% endcode %}

Then we can execute the Stripe native method such as update in the front end.

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.update({ amount: total });
```

{% endcode %}
