javascript - Google map 嵌入 + 搜索框

标签 javascript google-maps google-maps-api-3

我正在尝试为我的网站制作一张 map ，它将显示一些餐馆的标记。 我还希望人们能够搜索 map ，这样他们就可以查找地址并能够看到该地区的餐馆。 我得到了带有我想要的标记的 map 代码:

 <script src='https://maps.googleapis.com/maps/api/js?key=&sensor=false&extension=.js'></script>

我找到了这段代码来添加搜索框(带有自动完成功能，这对我来说很重要): https://google-developers.appspot.com/maps/documentation/javascript/examples/places-searchbox

但我似乎不知道如何将两者混合在一起以使它们一起工作。我的编码知识仍然非常有限:(

我非常感谢您的帮助!

谢谢
