Question

我正在使用d3.js图表及其依赖的数据如下：

 var graph = {
                                      "nodes" : [{"name" : "Appointments"},{"name" : "Store Visit"},{"name" : "Visit History"},{"name" : "Resume Store Visit"}], 
                                      "links" : [{"source":"Store Visit","target":"Appointments","value":6},
                                                {"source":"Appointments","target":"Visit History","value":7},
                                                {"source":"Visit History","target":"Store Visit","value":2},
                                                {"source":"Resume Store Visit","target":"Visit History","value":1},
                                                {"source":"Appointments","target":"Resume Store Visit","value":5}]
                                                };

我的REST服务返回完全相同的数据，但属性名称是Source，Target和Value（注意首字母大写）

这会打破错误

Uncaught TypeError: Cannot read property 'weight' of undefinedl.start @ d3.v3.min.js:4(anonymous function) @ userflowd3.html:64(anonymous function) @ d3.v3.min.js:1t @ d3.v3.min.js:1u @ d3.v3.min.js:1

那么，json返回data.items将属性值替换为小写的方式是什么？

Answer 1

所以我必须这样做像

finish_coordinates.X = ...

d3.js图数据属性案例敏感
