PayPal express checkout integration with multiple buttons on one page

Question

I currently have a list of items with a Paypal button associated with each of them. Each item will be purchased separately by clicking on its associated button.

<ul>
    <li data-id="1">Item 1 <div class="paypal-button"></div></li>
    <li data-id="2">Item 2 <div class="paypal-button"></div></li>
    <li data-id="3">Item 3 <div class="paypal-button"></div></li>
</ul>

<script src="https://www.paypalobjects.com/api/checkout.js"></script>

<script>
    paypal.Button.render({
        // options
    }, '.paypal-button');
</script>

Unfortunately, it seems that paypal.Button.render() will only render the first element that it finds.

Is it possible to do this call on multiple elements?

Answer 1

You need to give each element a unique id, then call render multiple times:

<ul>
    <li data-id="1">Item 1 <div id="button-1"></div></li>
    <li data-id="2">Item 2 <div id="button-2"></div></li>
    <li data-id="3">Item 3 <div id="button-3"></div></li>
</ul>

<script src="https://www.paypalobjects.com/api/checkout.js"></script>

<script>
    [ '#button-1', '#button-2', '#button-3' ].forEach(function(selector) {
        paypal.Button.render({
            // options
        }, selector);
    });
</script>
