我想知道当我使用 Google Maps API v3 单击 infoWindow 时如何触发事件。在此示例中，当我单击标记时，会显示一个信息窗口，其中包含一条独特的消息，具体取决于我单击的标记。我还希望能够单击信息窗口并显示一个警报，上面写着

“您点击了（__填写空白位置_）的信息窗口

我发现了一些使用 Google Maps API v2 和 jQuery 的示例，但不仅仅是简单的旧 Google Maps API v3。

好的，我想通了infoWindow，但后来我也想通了，InfoBox因为它更漂亮，更可定制。我是 JavaScript 新手，这些闭包可能非常棘手。

InfoWindow 对象没有“单击”事件，因此您不能这样做

google.maps.event.addListener(infowindow, 'click',....

相反，您可以将事件处理程序附加到 DOM 对象，例如

function addMarker(latLng, name){

var marker = new google.maps.Marker({
    map:map,
    position:latLng
});

G.event.addListener(marker,'click',function(mev){
        var div = document.createElement('div');
        div.innerHTML = name;
        div.onclick = function(){iwClick(name)};
        infoWindow.setContent(div);
        infoWindow.setPosition(mev.latLng);
        infoWindow.open(map);

    });
}

function iwClick(str){
    alert(str);
};

你用它来称呼它

var chicago = new google.maps.LatLng(41.850033, -87.6500523);
addMarker(chicago,'chicago');

为了使信息窗口可点击，或者您想在点击信息窗口内的任何标签时触发功能，dom 必须准备好。因此，当 dom 准备好时，您可以调用一个函数。

google.maps.event.addListener(infowindow, 'domready', function() {
            document.getElementById('yourId').addEventListener("click", yourFucntionToCall);
            function yourFucntionToCall() {
              Your fucntion code......
            }
          });

谢谢！艾琳就是你！你解决了我的问题！我已经打了4天了！如果您不熟悉闭包，则*会很痛苦。

这是我的工作代码（Sencha Touch 2 和 Google maps API v3）。它只允许打开一个信息窗口。

var openedInfoWindow = null;
var boxList = [];
var marker, i;

//build info box object
var infoWindow = new google.maps.InfoWindow({
    enableEventPropagation: true,
});

//handle close
google.maps.event.addListener(infoWindow, 'closeclick', function() {
    openedInfoWindow = null;
});

//loop trough store data...
for(i in data) {
    //data
    var itemData = data[i].getData();

    //marker
    var geopos = new google.maps.LatLng(itemData['lat'], itemData['lng']);
    var marker = new google.maps.Marker({
        position: geopos,
        //icon: image,
        map: map,
        title: itemData['title'],
        id: i,
        animation: google.maps.Animation.DROP
    });

    //add info window content to DOM
    var boxText = document.createElement("div");
    boxText.id = i;
    boxText.className = "labelText" + i;
    boxText.data = itemData;
    boxText.innerHTML = '<b>' + itemData['title'] + '</b>' + (itemData['distance'] ? ' (' + itemData['distance'] + ')' : '') + '<br />' + (itemData['address'] != itemData['title'] ? itemData['address'] : '') + (itemData['price'] ? '<br />' + itemData['price'] : '') + '<br /><a class="button">Meer info</a>';
    boxList.push(boxText);

    //add marker click event
    google.maps.event.addListener(marker, 'click', (function(marker, i) {
        if (openedInfoWindow != null)
            openedInfoWindow.close();

        return function() {
            infoWindow.setContent(boxList[this.id]);
            infoWindow.open(map, marker);
            openedInfoWindow = infoWindow;
        }
    })(marker, i));

    //when infowindow is clicked, open view...
    google.maps.event.addDomListener(boxList[i],'click',(function(marker, i) {
        return function(){
            iStuddy.app.pushView('kames_detail',boxList[i].data);
        }
    })(marker, i));
}

我的解决方案：尝试在 xml 中使用 onClick

<InfoWindow  onCloseClick={props.onToggleOpen}>
     <div onClick={()=>{alert('hello')}} class="wow slideInLeft">
        <img src="https://i.imgur.com/7IgBxnH.jpg" width="150px" />
        <div>nhà trọ cho thuê</div>
         <div>1.500.000đ</div>
     </div>
 </InfoWindow>

谢谢你们的评论。我设法（在阅读了您的建议后）构建了一个无需修改Infowindow代码即可工作的示例。

infoWindow本身应该只包含一个具有唯一 id 的占位符div：

    <InfoWindow
        marker={this.state.activeMarker}
        visible={this.state.showingInfoWindow}
        onOpen={e => {
          this.onInfoWindowOpen(this.props, e);
        }}
      >
        <div id="xyz" />
      </InfoWindow>

在Mapcontainer内部，您定义了一个 onInfoWindowOpen 回调，它插入一个带有 onClick 事件的组件/容器并将其渲染到占位符div：

    onInfoWindowOpen = () => {
        const button = (<button 
        onClick={
            () => {
            this.viewClinic(this.state.selectedPlace.slug)
            }
            }>
            View Details
        </button>);
        ReactDOM.render(React.Children.only(button),document.getElementById("xyz"));
        }

这是一个工作示例：
