在Javascript for IE11中将Child的文件输入对象传递给Parent窗口(Passing File Input Object of Child to Parent window in Javascript for IE11)

 终于弄清楚这个了解更多...它现在有意义，但之前没有。 这是新的'display'函数，将由OP中的一个替换。 当然，还需要进行一些其他更改...例如，在新信息窗口中显示所有聚类标记数据，但这是让窗口工作的要点。 
 
 //集群函数做东西函数multiChoice（clickedCluster）{//集群标记 
 var markers = clickedCluster.getMarkers（）; 
 
if (markers.length > 1)
{
    //create the info window
    var infoWindow = new google.maps.InfoWindow({
        content: ''+
            '<p>'+markers.length+' = length</p>'+
            '<p>testing blah blah</p>',
        position: clickedCluster.center_
    });

    //display the infowindow
    infoWindow.open(clickedCluster.map_);

    return false;
}
return true;
 
 }; 

Finally figured this out playing around with it some more... it makes sense now, but didn't before. Here is the new 'display' function to be replaced by the one in the OP. Of course, there are a few other change needed yet... showing all clustered marker data in the new info window for example, but this is the gist of getting the window to work.
 
//cluster function to do stuff function multiChoice(clickedCluster) { //clusters markers
 var markers = clickedCluster.getMarkers();
 
if (markers.length > 1)
{
    //create the info window
    var infoWindow = new google.maps.InfoWindow({
        content: ''+
            '<p>'+markers.length+' = length</p>'+
            '<p>testing blah blah</p>',
        position: clickedCluster.center_
    });

    //display the infowindow
    infoWindow.open(clickedCluster.map_);

    return false;
}
return true;
 
};
