Google Places JS API 显示评论

Question

JS API，不是网络服务：

我无法显示包含在地点详情回复中的 0-5 条评论： https://developers.google.com/maps/documentation/javascript/places#place_details_responses

到目前为止，我已经能够显示这些项目：

• details.name
• details.rating
• details.open_now
• details.formatted_address
• details.types
• details.formatted_phone_number

但当我尝试显示 details.reviews 时，它只会显示：

[对象对象],[对象对象],[对象对象],[对象对象],[对象对象]

有没有人成功展示评论？

details.reviews 不返回字符串（您在输出中得到的是该数组的字符串表示形式），它是一个最多包含 5 个评论对象的数组。您必须遍历此数组的项目并自行准备输出。

准备评论的示例函数：

(function (rs /*reviews-array*/ , fx /*review-parser*/ ) {
        var list = document.createElement('ul');
        rs.forEach(function (r) {
            list.appendChild(fx(r));
        });

        return '<ul>' + list.innerHTML + '</ul>';
        //remove the previous line when you want to return a DOMNode
        return list;
    }
    (details.reviews,
        function (r /*single review*/ ) {
            console.log(r.aspects)
            var item = document.createElement('li'),
                review = item.appendChild(document.createElement('ul'))
            props = {
                author_name: 'author',
                rating: 'rating',
                text: 'text'
            };
            item.appendChild(document.createElement('h6'));
            item.lastChild.appendChild(document.createElement('a'));
            item.lastChild.lastChild
               .appendChild(document.createTextNode(r.author_name));
            if (r.author_url) {
                item.lastChild.lastChild.setAttribute('href', r.author_url);
            }
            item.lastChild.appendChild(document.createTextNode('(' + r.rating +
                ')'));
            if (r.aspects && r.aspects.length) {
                item.appendChild(document.createElement('ul'));
                r.aspects.forEach(function (a) {
                    item.lastChild.appendChild(document.createElement(
                        'li'));
                    item.lastChild.lastChild
                        .appendChild(document.createTextNode(a.type +
                            ':' + a.rating))
                });
            }
            item.appendChild(document.createElement('p'));
            item.lastChild.appendChild(document.createTextNode(r.text));
            return item;
        }
    ))
