Question

嗨，我在Angular 5中集成了PayPal。我使用此功能渲染Paypal按钮

ngAfterViewChecked(): void {
    if (!this.addScript) {
      this.addPaypalScript().then(() => {
        this.abbonamenti.forEach((item, index) => {
          paypal.Button.render(this.payPalConfig +index, '#paypal-checkout-btn' + index);
          this.paypalLoad = false;
        })
        })
      }
  }

这需要为每个按钮加载不同的PayPal配置：

    payPalConfig = {
  env: 'sandbox',
    client: {
                sandbox:    'AfOCNI-QeZrhkX2lT5e4xY0S2KTfgoDarEXwk4mkK0ge4EoeW25VN5cg5ZlNRrdJrWUctHWBGGbP4d2V',
                production: 'AUiobQL_EOnmPB4ytmb5ZZHbLZT4hXk7UZgMzGwkd8HFIR6qZ5qJZM3JOb91O4y5frw4197ygPyfbor0'
            },
    commit: true,

            // payment() is called when the button is clicked
            payment: function(data, actions) {

              // Make a call to the REST api to create the payment
                return actions.payment.create({
                    payment: {
                        transactions: [
                            {
                                amount: { total: 40, currency: 'EUR' }
                            }
                        ]

            }
                });
            },
    // onAuthorize() is called when the buyer approves the payment
            onAuthorize: function(data, actions) {

                // Make a call to the REST api to execute the payment
                return actions.payment.execute().then(function() {
                    window.alert('Payment Complete!');
                });
            }
  };

，但是某些串联或索引也不起作用。如果我尝试在函数名称中添加+索引，则会出现语法错误。我不知道。我很沮丧。

您不能在对象上应用+运算符。参见下面的行

paypal.Button.render(this.payPalConfig +index, '#paypal-checkout-btn' + index);

上面一行中的this.payPalConfig是object，它导致了此错误。

您应该删除+和index，只需传递直接对象

 paypal.Button.render(this.payPalConfig, '#paypal-checkout-btn' + index);

配置应为

      payPalConfig = new PayPalConfig(PayPalIntegrationType.ClientSideREST, PayPalEnvironment.Sandbox, {
        commit: true,
        client: {
          sandbox: 'yourSandboxClientId',
        },
        button: {
          label: 'paypal',
        },
        onPaymentComplete: (data, actions) => {
          console.log('OnPaymentComplete');
        },
        onCancel: (data, actions) => {
          console.log('OnCancel');
        },
        onError: (err) => {
          console.log('OnError');
        },
        transactions: [{
          amount: {
            currency: 'USD',
            total: 9
          }
        }]
      });

运算符“ +”不能应用于类型
