Question

我创建了一个地点搜索Google地图，喜欢搜索学校类型之类的地点，我为私人和公共场所创建了一个标记，搜索框可用，但是当我单击Enter时，它不会显示公共/私人场所学校，这是因为我的代码吗？在图标上？或标记？

唯一的问题是当我单击Enter时，它不显示其标记

未声明图标。您需要检查输入内容以查看是否输入了私立学校或公立学校，然后相应地设置图标。

// Create a marker for each place.
var marker = new google.maps.Marker({
        map: map,
        title: place.name,
        position: place.geometry.location
});

if(place.name.toLowerCase() === 'private school') {
  marker.setIcon('http://i67.tinypic.com/2utkz8k.png');
}
else if(place.name.toLowerCase() === 'public school') {
  marker.setIcon('http://i68.tinypic.com/xcnnz4.png');
}

markers.push(marker);

我的搜索没有在Google地图中显示其标记的问题是什么？
