Javascript Bing地图-在图钉上调用单击事件
我有以下bing地图: 当在左侧列表中选择一家商店时,地图会自动在该图钉上居中,我现在需要做的是调用该图钉的click()句柄(或显示相关的信息框) 问题是,我正在将PIN推入一个Javascript Bing地图-在图钉上调用单击事件,javascript,bing-maps,Javascript,Bing Maps,我有以下bing地图: 当在左侧列表中选择一家商店时,地图会自动在该图钉上居中,我现在需要做的是调用该图钉的click()句柄(或显示相关的信息框) 问题是,我正在将PIN推入一个Microsoft.Maps.EntityCollection()调用了dataLayer,因此我无法直接调用map.entities.get(),或者更确切地说,如果我尝试以这种方式调用它,get()不会返回任何内容 注意这段代码底部的zoomMap()函数,我已经注释掉了有问题的行 如何调用click事件 var-

我只是在2,3个地方对你的代码做了一点修改,使之接近你的目标。请检查以下内容:
