在Bing Maps中将光标设置为空心手

key*_*red 2 bing-maps

我正在使用Bing Maps AJAX V7 map API进行开发,我正在尝试将光标设置为不同的东西,同时将鼠标悬停在不同的地图元素上.例如,当鼠标滚过图钉时,这就是我正在做的事情:

Microsoft.Maps.Events.addHandler(g_map, "mousemove", function (event) {
    if (event.targetType === "pushpin") {
        g_map.getRootElement().style.cursor = "pointer";
    }
});

我无法弄清楚的是如何在用户将鼠标移出图钉后恢复正常功能.我想也许可以将光标设置为鼠标中心上的指针,然后返回鼠标左边的非指针,但我不确定这是不是最好的方法.

您正在基本地图上使用该事件,因此我建议在图钉本身上绑定事件,以避免对此特定事件进行不必要的调用.

但是如果你想更新你的代码,这里有一个真正有用的完整例子,因为'hand'是Bing Maps中的默认元素,而鼠标位于基本地图上,请参阅代码:

如果您想要基于图钉事件的推荐方法:
