Sample script I found which would disable the submit button:

<script type="text/javascript">
function checkEnableSubmit() {
var text1 = document.getElementById('text1'),
submitBtn = document.getElementById('submitBtn');
submitBtn.disabled = (text1.value != "GOLD");
}
</script>

Allowing the user to enter in a custom amount would allow us to bill clients using this plugin. We could e-mail invoices and just give them a link to our payment page allowing them to enter in the amount of their invoice and submit it online.

You could create an ajax script that disables the “Submit” button if an amount below .50 is entered and gives you an error message.

Any way to enter in a custom amount?

I’ve checked every other Stripe payment gateway and this is the single lacking feature.

Not to mention your plugin is one of the few that is compatible with 3.9
