我試圖在Rails 3.2應用程序中使用Google可視化庫。我在application.html.erb以下谷歌可視化庫不加載Rails 3.2和咖啡
<head>
<title>Website</title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<%= csrf_meta_tags %>
</head>
我已經在我的stuff.js.coffee如下:
google.load('visualization', '1', packages: ['gauge'])
google.setOnLoadCallback(drawChart)
drawChart ->
data = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Memory', 80],
['CPU', 55],
['Network', 68]
])
options = {
width: 400, height: 120,
redFrom: 90, redTo: 100,
yellowFrom:75, yellowTo: 90,
minorTicks: 5
}
chart = new google.visualization.Gauge(document.getElementById('result'))
chart.draw(data, options)
我得到一個js錯誤時的頁面加載:未捕獲ReferenceError:谷歌沒有定義
如果我將圖表設置/創建js上移到application.hmtl.erb中,它一切正常。顯然沒有按照正確的順序在這裏加載。
