我有谷歌地图在地图上动态地从我的数据库加载位置。问题是它没有显示每个位置正确的显示信息。它仅显示所有标记上最后一个产品的信息。我需要以某种方式迭代每个标记。我的代码如下:
<section class="content jumbotron jumbotron-full-height">
<div class="item slide-1">
<div id="home-map"></div>
</div>
</section>
<script>
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('home-map'), {
center: {lat: 52.1326, lng: 5.2913},
zoom: 6,
mapTypeId: 'roadmap',
styles: [
{
featureType: 'all',
stylers: [
{ saturation: 0 }
]
},{
featureType: 'road.arterial',
elementType: 'geometry',
stylers: [
{ hue: '#00ffee' },
{ saturation: 0 }
]
},{
featureType: 'poi.business',
elementType: 'labels',
stylers: [
{ visibility: 'off' }
]
},{
featureType: 'road',
elementType: 'labels',
stylers: [
{ visibility: 'on' }
]
}
]
});
{% for product in products %}
var contentString = '<div class="info-window">'+
'<div id="siteNotice">'+
'</div>'+
'<div id="window-content">'+
'{% set path = product.image is not null ? product.image.path|imagine_filter(filter|default('sylius_shop_map_thumbnail')) : 'http://placehold.it/200x200' %}'+
'<img src="{{ path }}" />'+
'<h1>{{ product.code }}</h1>'+
'</div>'+
'<h2>{{ product.city }} - {{ product.country }}</h2>'+
'<p><strong> Description: </strong>{{ product.shortDescription }}</p>'+
'<p><strong> Price: </strong>from {{ product.price|sylius_price }} a day.</p>'+
'<a class="btn btn-primary" href="{{ path("sylius_shop_product_show", {"slug": product.slug}) }}">more info</a>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString,
maxWidth: 600
});
var marker = new google.maps.Marker({
position: {lat: {{ product.latitude }}, lng: {{ product.longitude }}},
map: map,
title: '{{ product.city }}',
label: '{{ product.address }}'
});
marker.addListener('click', function() {
infowindow.open(map, marker);
});
{% endfor %}
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC1c34AXAQ5Y3yV43Alj_ieMRaDPb0qZ44&callback=initMap" async defer>

答案 0 :(得分:0)
问题是您没有动态设置其内容。为此,您必须从另一个函数
创建标记 <section class="content jumbotron jumbotron-full-height">
<div class="item slide-1">
<div id="home-map"></div>
</div>
</section>
<script>
var map,infowindow;
function initMap() {
map = new google.maps.Map(document.getElementById('home-map'), {
center: {lat: 52.1326, lng: 5.2913},
zoom: 6,
mapTypeId: 'roadmap',
styles: [
{
featureType: 'all',
stylers: [
{ saturation: 0 }
]
},{
featureType: 'road.arterial',
elementType: 'geometry',
stylers: [
{ hue: '#00ffee' },
{ saturation: 0 }
]
},{
featureType: 'poi.business',
elementType: 'labels',
stylers: [
{ visibility: 'off' }
]
},{
featureType: 'road',
elementType: 'labels',
stylers: [
{ visibility: 'on' }
]
}
]
});
infowindow = new google.maps.InfoWindow({
maxWidth: 600
});
{% for product in products %}
createMarker(product )
{% endfor %}
}
function createMarker(product){
var contentString = '<div class="info-window">'+
'<div id="siteNotice">'+
'</div>'+
'<div id="window-content">'+
'{% set path = product.image is not null ? product.image.path|imagine_filter(filter|default('sylius_shop_map_thumbnail')) : 'http://placehold.it/200x200' %}'+
'<img src="{{ path }}" />'+
'<h1>{{ product.code }}</h1>'+
'</div>'+
'<h2>{{ product.city }} - {{ product.country }}</h2>'+
'<p><strong> Description: </strong>{{ product.shortDescription }}</p>'+
'<p><strong> Price: </strong>from {{ product.price|sylius_price }} a day.</p>'+
'<a class="btn btn-primary" href="{{ path("sylius_shop_product_show", {"slug": product.slug}) }}">more info</a>'+
'</div>';
var marker = new google.maps.Marker({
position: {lat: {{ product.latitude }}, lng: {{ product.longitude }}},
map: map,
title: '{{ product.city }}',
label: '{{ product.address }}'
});
marker.addListener('click', function() {
infowindow.setContent(contentString);
infowindow.open(map, marker);
});
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC1c34AXAQ5Y3yV43Alj_ieMRaDPb0qZ44&callback=initMap" async defer>
</script>
务必将infowindow声明为全局变量
