我目前正在学习upskill教程“ The Essential Web Developer Course”(当前在第162课上),在该教程中,我尝试将Stripe与高级会员的费用联系起来。本教程使用的是旧版的gem和库等,这就是为什么我要告诉你的原因。
问题是,在Stripe将我的客户令牌发回给我之后。它不会存储在我的数据库中,也不会登录到成员身份。相反,我的提交按钮将保持禁用状态,并显示字符串“ Processing”。
开发控制台显示以下消息:“未捕获的TypeError:无法读取未定义的属性'submit'”。
我需要更改什么?有……。与我的save_with_subscription方法有关?
attr_accessor :stripe_card_token
def save_with_subscription
if valid?
customer = Stripe::Customer.create(description: email, plan: plan_id, card: stripe_card_token)
self.stripe_customer_token = customer.id
save!
end
它的js文件:
/* global $, Stripe */
//Document ready.
$(document).on('turbolinks:load', function(){
var theForm = $('#pro_form');
var submitBtn = $('#form-signup-btn');
//Set Stripe public key.
Stripe.setPublishableKey( $('meta[name="stripe-key"]').attr('content') );
//When user clicks form submit btn,
submitBtn.click(function(event){
//prevent default submission behavior.
event.preventDefault();
submitBtn.val("Processing").prop('disabled', true);
//Collect the credit card fields.
var ccNum = $('#card_number').val(),
cvcNum = $('#card_code').val(),
expMonth = $('#card_month').val(),
expYear = $('#card_year').val();
//Use Stripe JS library to check for card errors.
var error = false;
//Validate card number.
if(!Stripe.card.validateCardNumber(ccNum)) {
error = true;
alert('The credit card number appears to be invalid');
}
//Validate CVC number.
if(!Stripe.card.validateCVC(cvcNum)) {
error = true;
alert('The CVC number appears to be invalid');
}
//Validate expiration date.
if(!Stripe.card.validateExpiry(expMonth, expYear)) {
error = true;
alert('The expiration date appears to be invalid');
}
if (error) {
//If there are card errors, don't send to Stripe.
submitBtn.prop('disabled', false).val("Sign Up");
} else {
//Send the card info to Stripe.
Stripe.createToken({
number: ccNum,
cvc: cvcNum,
exp_month: expMonth,
exp_year: expYear
}, stripeResponseHandler);
}
return false;
});
//Stripe will return a card token.
function stripeResponseHandler(status, response) {
//Get the token from the response.
var token = response.id;
//Inject the card token in a hidden field.
theForm.append( $('<input type="hidden" name="user[stripe_card_token]">').val(token) );
//Submit form to our Rails app.
theForm.get(0).submit();
}
});
