谷歌地图V3处理点击信息窗口里面的元素

问题描述 投票：1回答：2

总而言之一句话，我尽量做到：

  • 在地图上的信息窗口单，因为许多标记，
  • 附连到标记信息窗口内容
  • 信息窗口上的标记的点击打开从附着属性=>内容
  • 信息窗口包含2个按钮=>设定的开始，设定的目标
  • 如果起点和目标设定，计算路径

我想了很多，这是相当困难的一个处理程序附加到按钮的信息窗口内。我找到了最好的提示是这样的一个：Adding event to element inside Google Maps API InfoWindow

我想这至今：

<script>
function initialize() {
    var mapOptions = {
        center: new google.maps.LatLng(50.903033, 11.359863),
        zoom: 6,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        disableDefaultUI: true,
        zoomControl: true,
        scaleControl: true,
        overviewMapControl: true
    };
    var map = new google.maps.Map(document.getElementById('limousine-map'),
        mapOptions);
    var directionsService = new google.maps.DirectionsService();
    var directionDisplay = new google.maps.DirectionsRenderer();
    directionDisplay.setMap(map);
    directionDisplay.setPanel(document.getElementById('route-details'));
    var infoWindow = new google.maps.InfoWindow();
    var endPoint = false;
    var startPoint = false;


var marker = new google.maps.Marker({
    map: map,
    position: new google.maps.LatLng(50.903033, 11.359863),
    title: 'Test1'
});
marker.infoWindowContent = [
    '<div id="infoWindow"><strong>Test</strong>',
    '<button class="button" id="selectStart">Start</button>'+
    '<button class="button" id="selectTarget" style="float: right;">Target</button></div>'
].join('<br>');

google.maps.event.addListener(marker,'click',function(){
    infoWindow.close();
    infoWindow = new google.maps.InfoWindow({
        content: this.infoWindowContent
    });
    infoWindow.open(map,this);
    clickedLocation = this;
    google.maps.event.addListener(infoWindow, 'domready', function() {
        $('#infoWindow button').on('click',function(){
            console.log(clickedLocation);
            if($(this).attr('id') == 'selectStart'){
                startPoint = clickedLocation;
            }
            if($(this).attr('id') == 'selectTarget'){
                endPoint = clickedLocation;
            }
            recalcRoute();
        });
    });
});

var marker2 = new google.maps.Marker({
    map: map,
    position: new google.maps.LatLng(52.903033, 12.359863),
    title: 'Test2'
});
marker2.infoWindowContent = [
    '<div id="infoWindow"><strong>Test2</strong>',
    '<button class="button" id="selectStart">Start</button>'+
            '<button class="button" id="selectTarget" style="float: right;">Target</button></div>'
].join('<br>');

google.maps.event.addListener(marker2,'click',function(){
    infoWindow.close();
    infoWindow = new google.maps.InfoWindow({
        content: this.infoWindowContent
    });
    infoWindow.open(map,this);
    clickedLocation = this;
});



//Route painting
function recalcRoute(){
    if(startPoint != false && endPoint != false){
        var request = {
            origin: startPoint,
            destination: endPoint,
            travelMode: google.maps.TravelMode.DRIVING,
            unitSystem: google.maps.UnitSystem.METRIC
        };
        directionsService.route(request, function(response, status){
            if(status == google.maps.DirectionsStatus.OK){
                $('#route-details').parent().fadeIn();
                directionDisplay.setDirections(response);
            }
        });
    }else{
        directionDisplay.setDirections(null);
    }
}

}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

我得到了处理工作，但随后的路由计算不起作用。我得到这样一个错误

Uncaught Error: Invalid value for property <origin>: [object Object] 
thrown at line: directionsService.route(request, function(response, status){

我如何绑定一个事件信息窗口内的按钮，还自称recalcRoute？我也试着设置onclick上的按钮，而是参考recalcRoute是未知的。

为什么$('#infoWindow button').on('click',function(){ console.log('test'); });不工作？

  1. 从HTML点击听众访问的变量，他们需要在全球范围内。
  2. 该路线服务的起点和终点必须google.maps.LatLng可以地理编码为地址，而不是google.maps.Marker对象的对象或字符串。标志物的google.maps.LatLng可以与被检索： marker.getPosition（）。

您应该能够建立contentWindow的HTML，然后单击只需一次操作，然后一遍一遍地使用它们。

在需要改变的contentWindow的唯一的事情就是标题，以反映点击标记的标题。

像这样的东西应该这样做：

function initialize() {
    var mapOptions = {
        center: new google.maps.LatLng(50.903033, 11.359863),
        zoom: 6,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        disableDefaultUI: true,
        zoomControl: true,
        scaleControl: true,
        overviewMapControl: true
    };
    var map = new google.maps.Map(document.getElementById('limousine-map'), mapOptions);
    var directionsService = new google.maps.DirectionsService();
    var directionDisplay = new google.maps.DirectionsRenderer();
    directionDisplay.setMap(map);
    directionDisplay.setPanel(document.getElementById('route-details'));

    var Route = {
        var request = {
            origin: null,
            destination: null,
            travelMode: google.maps.TravelMode.DRIVING,
            unitSystem: google.maps.UnitSystem.METRIC
        };
        this.setOrigin = function(m) { request.origin = m.getPosition(); };
        this.setDestination = function(m) { request.destination = m.getPosition(); };
        this.calc = function() {
            if(request.origin && request.destination) {
                directionsService.route(request, function(response, status) {
                    if(status == google.maps.DirectionsStatus.OK) {
                        $('#route-details').parent().fadeIn();
                        directionDisplay.setDirections(response);
                    }
                });
            } else {
                directionDisplay.setDirections(null);
            }
        }
    };

    var route = new Route();
    var clickedLocation;

    var $infoWindowContent = $([
        '<div class="infoWindowContent">',
        '<h3></h3>',
        '<button class="setOrigin">Start</button>',
        '<button class="setDestination" style="float: right;">Target</button>',
        '</div>'
    ].join(''));
    $infoWindowContent.find(".setOrigin").on('click', function() {
        route.setOrigin(clickedLocation);
        route.calc();
    });
    $infoWindowContent.find(".setDestination").on('click', function() {
        route.setDestination(clickedLocation);
        route.calc();
    });

    var infoWindow = new google.maps.InfoWindow();
    infoWindow.setContent($infoWindowContent.get(0));

    //Assuming array markerData to contain the data necessary for bujilding markers ...
    $.each(markerData, function(i, m) {
        var marker = new google.maps.Marker({
            map: map,
            position: new google.maps.LatLng(m.lat, m.lng),
            title: m.title
        });

        google.maps.event.addListener(marker, 'click', function() {
            clickedLocation = this;
            infoWindow.close();//necessary?
            $infoWindowContent.find("h3").text(this.getTitle());
            infoWindow.open(map, this);
        });
    });

}
google.maps.event.addDomListener(window, 'load', initialize);

未经测试

笔记：

  • 我包裹起来一切都与在Route()构造的路线，用一个实例route。
  • 我假定所有的标记数据被最初包含在markerData阵列，这是通过循环来创建许多标记物是必要的。
