我真的需要帮助一些人!!!! 如何在Google地图中的infowindow中创建一个按钮？ infowindow包含来自数据库的数据。我尝试在infowindow（infowincontent）内创建一个按钮或链接但是没有成功。 提前致谢
这是创建标记的代码
<script>
function initialize() {
initMap();
initAutocomplete();
}
function initAutocomplete() {
var infoWindow = new google.maps.InfoWindow;
// Create the search box and link it to the UI element.
var input = document.getElementById('pac-input');
var searchBox = new google.maps.places.SearchBox(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
// Bias the SearchBox results towards current map's viewport.
map.addListener('bounds_changed', function() {
searchBox.setBounds(map.getBounds());
});
var markers = [];
// Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener('places_changed', function() {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
// For each place, get the icon, name and location.
var bounds = new google.maps.LatLngBounds();
places.forEach(function(place) {
if (!place.geometry) {
console.log("Returned place contains no geometry");
return;
}
var icon = {
url: place.icon,

};
// Create a marker for each place.
markers.push(new google.maps.Marker({
map: map,
icon: icon,
title: place.name,
position: place.geometry.location
}));
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
map.fitBounds(bounds);
});

您可以为infowindows构建您喜欢的HTML代码这是一个链接，但您可以使用所有标记元素或使用css自定义链接
var myContentString =
'<div id="your_id" style="your_style...."><a href="your_link">' +
'My link Text comes here' +
'</a></div>';
var infowindow = new google.maps.InfoWindow({
content: myContentString,
maxWidth: 600
});
