我试图有一个谷歌地图，它从大地图放大到某个邮政编码，然后在放大到邮政编码后显示搜索到的项目（例如“披萨”）。搜索预设为例如比萨饼，您需要做的就是输入邮政编码。我已经创建了地图邮政编码，但我很难添加搜索功能。我找到了一些最接近我想要的代码，但我可以弄清楚如何删除搜索框并让它搜索预设搜索。（Google Maps API Places Library SearchBox）

这是我的缩放代码

这是我发现我想在没有搜索栏的情况下放入地图缩放代码的示例代码。

          zoom : 7,
          mapTypeId : google.maps.MapTypeId.ROADMAP

        google.maps.event.addListener(searchBox, 'places_changed', function() {

          for (var i = 0, marker; marker = markers[i]; i++) {

提前致谢！我会继续工作，如果我找到什么我会告诉你的。
