Question

我已经在我的asp.net网页中实现了paypal checkout express按钮。我怎样才能将orderTotal传递给金额：{total：'0.01'，currency：'USD'}。默认情况下它是'0.01'我想要显示实际的orderTotal。 这是我的代码 paypal.Button.render（{

            env: 'sandbox', // sandbox | production 

               // PayPal Client IDs - replace with your own 
               // Create a PayPal app: https://developer.paypal.com/developer/applications/create 
               client: { 
                sandbox: 'AZDxjDScFpQtjWTOUtWKbyN_bDt4OgqaF4eYXlewfBP4-8aqX3PiV8e1GWU6liB2CUXlkA59kJXE7M6R', 
                //production: 'AVSYgEO5SUewyQ_We4dW5uCXyEZHgcFDfKK15gCqsd7o0edVH5UOhtHK7n2uqkFQOYtjJt0vvemfgNwg' 
               }, 

               // Show the buyer a 'Pay Now' button in the checkout flow 
               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: '0.01', currency: 'USD' } 
                  } 
                  ] 
                 } 
                }); 
               }, 
               commit: true, 
               // 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!'); 
                 onPaypalAuthorize(); 
                }); 
               } 

              }, '#paypal-button-container');

根据您是否使用窗体或MVC。

Web窗体可以使用inline指令 <% =MyTotal %>，你想总。

随着MVC @ model.MyTotal会在哪里工作MyTotal将是你想总要传递给贝宝。

˚F或者例如，WebForms的

amount: { total: <% =MyTotal %>, currency: 'USD' } 

MVC

amount: { total: @Model.MyTotal, currency: 'USD' } 

一对夫妇的需要指出的事。总数需要是一个字符串，并且需要舍入到两位小数点。如果你不这样做，它会反弹和错误。
