Google Places JS API Show Reviews - google-maps-api-3

Question

JS API, not web service:
I'm having trouble displaying the 0-5 reviews included with the Place Details Responses:
https://developers.google.com/maps/documentation/javascript/places#place_details_responses
So far I have been able to display these items:
details.name
details.rating
details.open_now
details.formatted_address
details.types
details.formatted_phone_number
But when I try to show details.reviews it just displays:
[object Object],[object Object],[object Object],[object Object],[object Object]
Has anyone had any success displaying the reviews?
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>';
if (!!details.open_now) contentStr += '<li class="open-now">'+details.open_now+'</li>';
contentStr += '<li>'+details.formatted_address+'</li>';
contentStr += '<li class=gray>'+details.types+'</li>';
// Check for platform to send appropriate app link
if ((navigator.platform.indexOf("iPhone") != -1)) {
contentStr += '<li class="link"><a class=navLink href=http://maps.apple.com/?daddr=Current+Location&saddr='+navLink+'><i class="fa fa-automobile"></i> Get Directions</a></li>';
} else {
contentStr += '<li class="link"><a class=navLink href=https://www.google.com/maps/dir/Current+Location/'+navLink+'><i class="fa fa-automobile"></i> Get Directions</a></li>';
}
if (!!details.formatted_phone_number) contentStr += '<li class="link"><i class="fa fa-phone"></i> '+details.formatted_phone_number+'</li>';
if (!!details.reviews) contentStr += '<li>'+details.reviews+'</li>';
contentStr += '</ul>';
infowindow.setContent(contentStr);
infowindow.open(map,marker);
} else {
var contentStr = "<h5>No Result, status="+status+"</h5>";
infowindow.setContent(contentStr);
infowindow.open(map,marker);
}
});
});
}

details.reviews doesn't return a string(what you get in the output is the string-representation of this array), it's an array which contains up to 5 review-objects. you must iterate over the items of this array and prepare the output on your own.
A sample-function which prepares the reviews:
(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;
}
))
