JS API，而不是网络服务：
我无法显示地方详情回复中包含的0-5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：
但是当我尝试显示 details.reviews 时，它只会显示：
[object Object]，[object Object]，[object Object]，[object Object]，[object Object]
是否有人在显示评论时取得了成功？
function createMarker(place) {
var image = 'img/marker.png';
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
icon: image,
position: place.geometry.location
});
var request = { reference: place.reference };
service.getDetails(request, function(details, status) {
google.maps.event.addListener(marker, 'click', function() {
if (status == google.maps.places.PlacesServiceStatus.OK) {
// Replace empty spaces in navigation link with + symbols
var navLink = details.formatted_address;
navLink = navLink.replace(/\s/g, "+");
$('.navLink').html(navLink);
// Match Rating bar width to rating number
var ratingWidth = (details.rating*20)+"px";
$('.rating-bar > span').css('width', "'"+ratingWidth+"'");
var contentStr = '<h5 class="info-window-title">'+details.name+'</h5><ul class="info-window">';
if (!!details.rating) contentStr += '<li>Rating: <div class="rating-bar"><span style=width:'+ratingWidth+'></span></div><strong>'+details.rating+'</strong></li>';

details.reviews不返回字符串（输出中的内容是此数组的字符串表示形式），它是一个包含最多5个审阅对象的数组。你必须迭代这个数组的项目并自己准备输出。
准备评论的样本函数：
(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;
}
))
