如何使用Watson Conversation在屏幕上显示几条消息

问题描述

我正在使用Watson技术(更确切地说是通过对话服务)开发聊天机器人.这是我在Bluemix上使用javascript的第一个应用程序，并且我的聊天机器人的显示消息有问题.我解释:目前我有这个代码:

I'm working on a chatbot with Watson technology and more precisely with conversation service. It's my first application on Bluemix and with javascript and i have an issue with the display message of my chatbot. I explain: currently I have this code :

var text = response.output.text [0];//仅显示第一个值

还有我的函数 displayMessage

function displayMessage(text, user) {

        var chat = document.getElementById('chatBox');
        var bubble = document.createElement('div');
        bubble.className = 'message';  // Wrap the text first in a message class for common formatting

        // Set chat bubble color and position based on the user parameter
        if (user === watson) {
            bubble.innerHTML = "<div class='bot'>" + text + "</div>";
        } else {
            bubble.innerHTML = "<div class='user'>" + text + "</div>";
        }

        chat.appendChild(bubble);
        chat.scrollTop = chat.scrollHeight;  // Move chat down to the last message displayed
        document.getElementById('chatMessage').focus();

        return null;
}

当前的问题是该函数仅显示我的第一个值，但是在某些情况下，我必须显示n条消息(n始终< 10)因此，我考虑创建一个array [10]来用 while(array [i]！= undefined)存储我的消息.但是我的错误是函数displayMessage中的显示-我不知道如何显示多条消息.我试过了:

The problem currently is that the function only displays my first value, but in some cases I have to display n message (n is always < 10)So I think about the creation of an array[10] to store my message with while (array[i] != undefined). But my error is with the display in the function displayMessage - I don't know how display several messages. I tried this:

bubble.innerHTML = "<div class='bot'>" + tab[tmp] + "</div>";

和一个循环，虽然与我的声明相同，但没有用.

and a loop while same as in my declaration but it didn't work.

有人可以帮助我吗?

谢谢

编辑第1个通知您，这是我创建标签页时的第一个循环:

Edit n°1To inform you this is my first loop while creating my tab :

var tab = new Array(response.output.text[0]); // array with my different text
        var tmp = 1;
        while(response.output.text[tmp] != undefined){
            tab[tmp] = response.output.text[tmp]; // only display first value if second is null
            tmp = tmp + 1;
    }

推荐答案

有一种更简单的方法.JS允许您连接"数组中的所有元素:

There is a much easier approach. JS allows you to 'join' all the elements in an array:

text = response.output.text.join(" ");

那应该可以解决问题！
