D3.js - 对JSON文件的令人费解的解释？

Question

我正在使用的JSON文件的解释方式与我预期的不同。

外部JSON文件：

{"organizations":[{"member":{"source":"TCAN","target":"Resilient Toronto","category-source":"organization","category-target":"organization"}},{"member":{"source":"City of Toronto","target":"","category-source":"organization","category-target":""}},{"member":{"source":"Resilient Toronto","target":"City of Toronto","category-source":"organization","category-target":"organization"}},{"member":{"source":"Rita Bijons","target":"ZCO","category-source":"volunteer","category-target":"organization"}},{"member":{"source":"Rita Bijons","target":"Green 13","category-source":"volunteer","category-target":"community group"}},{"member":{"source":"Green 13","target":"TCAN","category-source":"community group","category-target":"organization"}},{"member":{"source":"ZCO","target":"TCAN","category-source":"organization","category-target":"organization"}}]}

我不明白为什么源字段被解释为对象而category-source不被解释为对象。是因为这个名字吗？为什么源对象中有类别字段？名字未定义？显然我缺少一些基本的理解。有没有记录在哪里？

Answer 1

我刚用PrettyPrint测试了你的JSON，并且格式正确。因此，问题在于您使用的软件/代码来显示（格式化）JSON数据。

Answer 2

看起来您正在通过force layout运行数据，并且它与您的媒体资源名称“来源”相冲突。具体来说，force.links调用将通过添加“source”和“target”属性来更改数据，这些属性看起来就像您引用的结构。

检查您是否在任何时候将数据传递给force.links。
