Javascript 基于用户选择的下拉字段的多个不同Google标记

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的选定值放置不同的多个标记，例如，用户选择的学校，标记将显示学校图标，而其他用户选择的教堂将显示教堂图标。谢谢

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
    });

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
    }
  }
}

显示提取标记时

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

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
    }
  }
}

函数隐藏标记（）{
对于（var i=0；i能否请您更具体一点，我不想隐藏任何标记您想选择specefic标记或动态更改其图标？基本上，我有一个用户可以选择位置的表单，提交表单后会发生什么？在谷歌地图中显示它。我想根据用户选择的图标更改图标p花边，当前它仅显示最后一个图标变量
