Question

我有一个简单的脚本，当您使用jQuery mobile和Google Maps API v3单击按钮时，会在地图上添加标记。我想在该标记中添加一个基本的infoWindow，这样当你点击它时，就会显示“Hello World”。

这似乎应该很容易，但我似乎无法使语法正确。我正在添加像这样的标记

$('#map_canvas').gmap('addMarker', { 'position': chicago } );

我似乎找不到任何一个很好的例子，当你设置标记时你也设置了一个infowindow。

这是我的代码。如果保存在jquery-ui-map-3.0-rc\demos\目录中，则所有路径都是正确的。点击“添加更多标记”后，chicago位置的标记会添加到地图中。我希望能够点击该标记并弹出一个信息窗口，上面写着“Hello World！”。

                $('.add-markers').click(function() {

            </div>
        </div>      
    </body>
</html>

如果我将$(document).ready(function()){}内的代码更改为以下内容，则标记甚至不再显示。

        $(document).ready(function()
        {
            initialize();
            $('.add-markers').click(function() {
                //$('#map_canvas').gmap('addMarker', { 'position': chicago, 'content': "Hello World!"} );
                $('#map_canvas').gmap({'callback': function() {
                    var self = this;
                    self.addMarker({'position': chicago }).click(function() {
                        self.openInfoWindow({ 'content': 'Hello World!' }, this);
                    });
                    }});
                });
            });

我添加了请求的打开信息窗口。请检查以下代码：
