Google Places API示例
[英]Google Places API example
問題描述
問題
我一直試圖讓這個谷歌地圖API示例工作，但在完全從谷歌的網站復制代碼后，該示例無法正確呈現。 即地圖完全無法渲染，搜索欄是-350px的頁面等。
看看我的意思，看看這個JSfiddle 。
這個例子在Google上面提到的文檔頁面上運行得很好，所以我知道它正在做的事情。 有任何想法嗎？
編輯：我從谷歌的網站獲得了CSS，但仍然存在問題。
以下是導致問題的代碼：

JS字段不接受外部資源的Google Maps API庫。 （我不確定為什么）所以你需要將<script>標簽插入到body字段中。
並且JS字段自動生成“window.onload”。 您不必在JS字段中編寫“google.maps.event.addDomListener”。

<input id="searchTextField" type="text" size="50">
<input type="radio" name="type" id="changetype-all" checked="checked">

<input type="radio" name="type" id="changetype-establishment">

你會注意到javascript控制台中的錯誤：
Failed to load resource: the server responded with a status of 404 (Not Found) http://fiddle.jshell.net/maps/documentation/javascript/examples/default.css
Uncaught ReferenceError: google is not defined fiddle.jshell.net/agconti/NpYwE/show/:133
您沒有在小提琴上正確包含Google API腳本。
Google會放置API圖標
