html页面在本地工作但在云端时不工作

标签: javascript html d3.js cloud9-ide

我正在尝试在简单的网页上呈现d3.js图表​​。图表非常简单。我从cloud9运行它,这通常是一个非常好的错误免费的基于云的IDE。但是,当我运行它时,页面是空白的。我可以得到简单的javascript函数,但是(警告和“你好世界”等),但不是d3.js.我不知道为什么。所以我在cloud9中运行html,然后从浏览器中“查看源代码”并将代码逐字复制粘贴到我的Mac笔记本电脑上的本地html页面并运行它,它工作正常。所以基本上我不明白为什么它在cloud9上不起作用。这是代码..

我刚刚在云端9中尝试过。当我运行html文件时,它给了我一个https链接。 Chrome正确地抱怨在安全页面上加载非安全资源:

Mixed Content: The page at 'https://demo-project-larsenmtl.c9.io/html/index.html' was loaded over HTTPS, but requested an insecure script 'http://d3js.org/d3.v3.min.js'. This request has been blocked; the content must be served over HTTPS.
index.html:38 Uncaught ReferenceError: d3 is not defined

尝试使用http链接或从支持https的cdn加载d3,例如cloudflare:

https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.5/d3.min.js

您有以下两次:

</head>
<body>

因此HTML无效。
