Currently, I am working on a solution to prevent users from submitting the stripe form when certain inputs are left empty. To achieve this, I have integrated stripe.js elements into my form and implemented the form submission handling within my vue component.
this.cardNumberElement.on('change', this.enableForm);
this.cardExpiryElement.on('change', this.enableForm);
this.cardCvcElement.on('change', this.enableForm);
Upon reviewing the documentation, I attempted to utilize the change event on inputs, but this approach proved ineffective as users could simply avoid typing anything and still click the submit button.
Below is a snippet of my vue component:
mounted()
{
console.log(this.$options.name + ' component successfully mounted');
this.stripe = Stripe(this.stripePK);
this.elements = this.stripe.elements();
this.cardNumberElement = this.elements.create('cardNumber', {style: this.stripeStyles});
this.cardNumberElement.mount('#card-number-element');
this.cardExpiryElement = this.elements.create('cardExpiry', {style: this.stripeStyles});
this.cardExpiryElement.mount('#card-expiry-element');
this.cardCvcElement = this.elements.create('cardCvc', {style: this.stripeStyles});
this.cardCvcElement.mount('#card-cvc-element');
let stripeElements = document.querySelectorAll("#card-number-element, #card-expiry-element, #card-cvc-element");
stripeElements.forEach(el => el.addEventListener('change', this.printStripeFormErrors));
this.cardNumberElement.on('change', this.enableForm);
this.cardExpiryElement.on('change', this.enableForm);
this.cardCvcElement.on('change', this.enableForm);
},
methods:
{
...mapActions('Stripe', ['addSource', 'createSourceAndCustomer']),
...mapMutations('Stripe', ['TOGGLE_PAYMENT_FORM']),
...mapMutations('Loader', ['SET_LOADER', 'SET_LOADER_ID']),
enableForm:function(event){
if(event.complete){
this.disabled = false;
}
else if(event.empty){
this.disabled = true;
}
},
submitStripeForm: function()
{
this.SET_LOADER({ status:1, message: 'Processing...' });
var self = this;
this.stripe.createSource(this.cardNumberElement).then(function(result) {
if (result.error) {
self.cardErrors = result.error.message;
}
else {
self.stripeSourceHandler(result.source.id);
}
});
},
stripeSourceHandler: function(sourceId)
{
console.log('stripeSourceHandler');
this.cardNumberElement.clear();
this.cardExpiryElement.clear();
this.cvcElement.clear();
if(this.customerSources.length == 0)
{
console.log('createSourceAndCustomer');
this.createSourceAndCustomer({ id: sourceId });
}
else
{
console.log('addSource');
this.addSource({ id: sourceId });
}
},
printStripeFormErrors: function(event)
{
if(event.error)
{
self.cardErrors = event.error.message
}
else
{
self.cardErrors = '';
}
}
}
