Question

从https://github.com/jacomyal/sigma.js下载了sigma.js zip 尝试基本加载gexf文件。不幸的是，html - load-external-gexf.html不会加载任何图形。

 *
 * The object given as the second parameter is the base of the instance
 * configuration object. The plugin will just add the "graph" key to it

sigma.parsers.gexf('data/arctic.gexf', {

文件arctic.gexf也出现在数据目录下。我使用的是Google Chrome 37

问题是什么？我能够在示例目录下加载其他示例htmls，但load-external-json.html也不起作用。

Answer 1

假设您没有在服务器上运行托管，因为Chrome的默认安全设置 - 它不会从硬盘驱动器加载文件（除非您正在运行服务器）。

使用开发人员工具，您会看到 XMLHttpRequest无法加载错误。

使用Firefox，您将不会遇到此限制，并且您无需运行服务器即可加载这些示例。

Sigma js无法加载外部gexf
