Question

我使用谷歌API和IGN API（法国地图）开发自己的地图，我想添加一个谷歌地图搜索框，但即使仔细阅读谷歌地图API，也无法找到成功的方法。

这就是我所拥有的： http://www.tiphainebuccino.com/site/Map/LaCarteAuxTresors_2.html

这是我要添加的内容（不会丢失我的实际设置）： https://developers.google.com/maps/documentation/javascript/examples/places-searchbox?hl=fr

我不明白如何混合两个HTML代码。有人可以帮帮我吗？我在html + javascript工作，而且我是初学者：）

谢谢

Answer 1

我在your map上收到此错误：

Uncaught TypeError: Cannot read property 'SearchBox' of undefined

加载API时需要include the places library。

变化：

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

要：

<script type="text/javascript" src="http://maps.google.com/maps/api/js?libraries=places&sensor=false"></script>

您的页面上也没有id =“pac-input”的元素。将其添加到您的HTML标记：

<input id="pac-input"></input>
