Question

我有以下代码来了解地图。除缩放参数外，一切正常。无论我为缩放设置什么，它总是显示相同的缩放级别。我该怎么办？

$('#pagemap').live("pageshow", function() {

            $('#map_canvas').gmap().bind('init', function(evt, map) {

                $('#map_canvas').gmap('getCurrentPosition', function(position, status) {

                        if ( status === 'OK' ) {

                            var clientPosition = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);

                            $('#map_canvas').gmap('option', 'mapTypeId', google.maps.MapTypeId.SATELLITE);

                            $('#map_canvas').gmap('option', 'zoom', 13);            

                            $('#map_canvas').gmap('addMarker', {'position': clientPosition, 'bounds': true});

                        }
                });   
            });
      });

Answer 1

您需要将标记的'bounds'选项更改为false。

$('#map_canvas').gmap('addMarker', {'position': clientPosition, 'bounds': false});

如果将属性边界设置为true，则地图将自动计算视口和缩放，覆盖构造函数中的任何缩放集块引用

Answer 2

我遇到了解决方案的问题。如果我将边界设置为false，则地图将保持在其初始中心坐标的中心。好的。那么为什么我的地图集中在一个远离针的点？好的，没问题。但是，如果我仍想在添加标记后设置特定的缩放级别？

$("your-selector").gmap('addMarker', { 
    'position': latlng, 
    'bounds': true
}, function(map, marker) {
    map.set('zoom', 12);
}).click(function() {
    $(this.container).gmap('openInfoWindow', { 'content': 'TEXT_AND_HTML_IN_INFOWINDOW' }, this);
});

你只需回调gmap功能。但是人们，是不是该修正这个插件的API文档中所有损坏链接的时候了？难道没有时间为任何插件编写指定且清晰的Javascript文档吗？让我们互相帮助，这种方式相当复杂。我们正在失去很多时间。

试试这个，看看这个＆＃34; zoom：9＆＃34;在代码中缩放级别......
