在微软机器人框架

Question

循环文件我一直在尝试Microsoftbot.dialog（“showShirts”动态创建卡，

function (session) { 
    var msg = new builder.Message(session); 
    msg.attachmentLayout(builder.AttachmentLayout.carousel) 
    msg.attachments([ 
     new builder.HeroCard(session) 
      .title("Classic White T-Shirt") 
      .subtitle("100% Soft and Luxurious Cotton") 
      .text("Price is $25 and carried in sizes (S, M, L, and XL)") 
      .images([builder.CardImage.create(session, 'http://petersapparel.parseapp.com/img/whiteshirt.png')]) 
      .buttons([ 
       builder.CardAction.imBack(session, "buy classic white t-shirt", "Buy") 
      ]), 
     new builder.HeroCard(session) 
      .title("Classic Gray T-Shirt") 
      .subtitle("100% Soft and Luxurious Cotton") 
      .text("Price is $25 and carried in sizes (S, M, L, and XL)") 
      .images([builder.CardImage.create(session, 'http://petersapparel.parseapp.com/img/grayshirt.png')]) 
      .buttons([ 
       builder.CardAction.imBack(session, "buy classic gray t-shirt", "Buy") 
      ]) 
    ]); 
    session.send(msg).endDialog(); 
}).triggerAction({ matches: /^(show|list)/i }); bot framework in node js, 
i saw this sample code in the documentation 

我的问题是，而不是手动键入新builder.HeroCard（）.. 。如何创建一个循环从一个JSON数组填充这个？

我已经试过这

var obj = require("./dummy_json"); 
msg.attachments([ 
    obj.shirts.forEach(function(data){ 
     new builder.HeroCard(session) 
      .title(data.title) 
      .subtitle(data.subtitle) 
      .text(data.text) 
      .images([builder.CardImage.create(session, data.image_path)]) 
      .buttons([ 
       builder.CardAction.imBack(session, data.title, "Buy") 
      ]) 
    },this) 
]);

的问题是使y你正在做循环，但似乎你没有添加任何东西到数组中。

尝试是这样的：一个用于/的forEach调用内部

var attachments = []; 
var obj = require("./dummy_json"); 

obj.shirts.forEach(function(data) { 
    var card = new builder.HeroCard(session) 
        .title(data.title) 
        .subtitle(data.subtitle) 
        .text(data.text) 
        .images([builder.CardImage.create(session, data.image_path)]) 
        .buttons([ 
         builder.CardAction.imBack(session, data.title, "Buy") 
        ]) 

    attachments.push(card); 
},this) 

msg.attachments(attachments);
