Question

我正在尝试使用jQuery Mobile，Google Maps API和Google Maps v3的地理位置标记来构建WebApp。我对js没有多少经验，但我努力了。我使用数组中的信息在for循环中创建标记。在Stackoverflow的帮助下，我可以实现我点击标记并获得方向。现在我请你帮助我，因为我只想点击按钮里面一个Infowindow时才能获得指示。我和另一个听众尝试过，但我想我真的不知道这是什么。

这是我的剧本：

<script type="text/javascript" charset="UTF-8">
    var ren = null;
    var GeoMarker = null;

    $(document).on('pageshow', '#index',function(e,data){ 

        $('#content').height(getRealContentHeight());
        // This is the minimum zoom level that we'll allow
        var locations = [

        ];

        var minZoomLevel = 16;
        var myLatlng = new google.maps.LatLng(52.0212250,8.5421740);

        var map = new google.maps.Map(document.getElementById('map_canvas'), {
            zoom: minZoomLevel,
            center: new google.maps.LatLng(52.0212250,8.5421740),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });

        var infowindow = new google.maps.InfoWindow();

        var marker, i;

        var GeoMarker = new GeolocationMarker();
        GeoMarker.setCircleOptions({fillColor: '#ABCDEF'});


        google.maps.event.addListener(GeoMarker, 'position_changed', function() {
            map.setCenter(this.getPosition());

        GeoMarker.setMap(map);


        for (i = 0; i < locations.length; i++) {
            marker = new google.maps.Marker({
                position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                map: map
            });

            google.maps.event.addListener(marker, 'click', (function (marker, i) {
                return function () {
                    infowindow.setContent('<div><h3>' + locations[i][0] + '</h3>' + '<p>' + locations[i][3] + '</p><button id="button" class="ui-btn ui-mini" type="submit">Navigation</button></div>');
                    infowindow.open(map, marker);
                    var navButton = document.getElementById('button');

                google.maps.event.addListener(navButton, 'click', function() {
                    if (ren && ren.getMap()) ren.setMap(null);

                    ren = new google.maps.DirectionsRenderer( {'draggable':false} );
                    ren.setMap(map);

                    })

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

    function getRealContentHeight() {
        var header = $.mobile.activePage.find("div[data-role='header']:visible");

        var content_height = viewport_height - header.outerHeight() - footer.outerHeight();
        if((content.outerHeight() - header.outerHeight() - footer.outerHeight()) <= viewport_height) {
            content_height -= (content.outerHeight() - content.height());
        } 
        return content_height;

你需要监听infowindow的domready事件。 https://developers.google.com/maps/documentation/javascript/reference?csw=1#InfoWindow

infoWindow = new google.maps.InfoWindow();

google.maps.event.addListener(infoWindow, 'domready', function() {

    // Bind the click event on your button here
});

希望这有帮助。

在Google Maps API InfoWindow中查看Button的方向
