Execute a script based on target #

Hi,

I’m trying to link a button to #checkoutID and when a user clicks the button I need to execute the stripe checkout script.

stripe.redirectToCheckout({
  lineItems: [{
    price: '{{checkoutID}}', 
    quantity: 1,
  }],
  mode: 'payment',
  successUrl: 'https://example.com/success',
  cancelUrl: 'https://example.com/cancel',
}).then(function (result) {
});

Due to certain features on my page, this is the simplest solution I have found so far.

Does anyone know of a code that would read anything after the # , save it into a variable and if it contains “checkout” the above script would be executed?

For example if the user clicks button A, which points to #checkoutID, the script will execute, and take the user to checkout.
