我正在为wordpress制作一个聊天机器人，用于与api.ai或dialogflow进行通信 我当前用于显示卡的代码如下所示：

var html = "<div class=\"myc-conversation-bubble myc-conversation-response myc-is-active myc-image-response\"><img src=\"" + imageUrl + "\"/></div>";
html+="<div class=\"myc-card-title\">" + title + "</div>"
html += "<div class=\"myc-card-subtitle\">" + subtitle+ "</div>";
html += "<input type=\"button\" " + "style=\"background-color:rgb(221, 153, 51);text-transform: none\"" + "class=\"myc-quick-reply\" value=\"" +buttons[0]+ "\" />";
var innerHTML = "<div class=\"myc-conversation-bubble-container myc-conversation-bubble-container-response\"><div class=\"myc-conversation-bubble myc-conversation-response myc-is-active myc-quick-replies-response\">" + html + "</div>";

var html=”“；
html+=“”+标题+“”
html+=“”+字幕+“”；
html+=“”；
var innerHTML=“”+html+”；

我正确地获取了图像、标题和副标题，但按钮显示为[object object]，正确的方法是什么？

按钮文本位于

文本属性中

尝试将
按钮[0]
替换为
按钮[0]。文本在您的示例中，按钮是一个对象数组，具有属性文本。因此，请尝试
按钮[0]。文本提供完整的
JSON
。
