Question

我能够根据显示信息框的用户输入创建多个标记，我当前的问题是如何根据用户选择的值放置不同的多个不同标记，例如用户选择的学校，标记将显示学校图标和其他用户选择的教堂，并将显示教堂图标。感谢

创建标记时为标记提供ID ..

var marker = new google.maps.Marker({
        position: latlng,
        map: map,
        icon: icons,
        id:"school"  //or church to your respective markers
    });

显示提取标记..

function hide_markers(){
  for(var i = 0; i<markers.length; i++){
    if(markers[i].id !=  "school")
    {
      markers[i].setVisible(false); //hide the markers whose id is not school
    }
  }
}

基于用户选择的下拉字段的多个不同的Google标记
