javascript - 使用orgchart时出错: Cannot read property '_aZ' of null

Question

我正在尝试使用此组织结构图库 http://www.getorgchart.com

使用很少的节点可以完美地工作，但是，当我尝试加载整个组织(大约 1100 个具有多个嵌套级别的主题)时，我收到此控制台错误:

未捕获类型错误:无法读取 null 的属性“_aZ”

并且无法显示图表。

任何帮助将不胜感激。 谢谢!

经过一番研究，我解决了这个问题。

问题是你需要先由 parent 订购你的数据源(文档中没有说明)；让我们在在客户端上初始化在线演示中看一下这个示例:

    $('#people').getOrgChart({
    theme: "vivian",
    primaryColumns: ["name", "title", "phone", "mail", "postcode"],
    imageColumn: "image",
    gridView: true,
    dataSource:[            
        { id: 1, parentId: null, name: "Elizabeth Horton", title: "Founder", phone: "(03) 9252 4642" , image: "images/f-46.jpg", mail:"elizabeth.horton@live.com", postcode: "PH2 2SR" },
        { id: 2, parentId: 1, name: "Emily Horton", title: "Fork lift operator", phone: "(08) 9015 4407", image: "images/f-45.jpg", mail:"emily.horton@live.com", postcode: "BA5 0AP"  },
        { id: 3, parentId: 1, name: "Robert Nolan", title: "Blockmason", phone: "(02) 6747 7998", image: "images/f-41.jpg", mail:"robert.nolan@live.com", postcode: "BH9 4NG"  },
        { id: 4, parentId: 1, name: "Callum Anderson", title: "System operator", phone: "(03) 5314 0473", image: "images/f-43.jpg", mail:"callum.anderson@live.com", postcode: "HR6 8ZF"  },
        { id: 5, parentId: 4, name: "Courtney John", title: "System operator", phone: "(03) 5314 0473", image: "images/f-42.jpg", mail:"courtney.john@live.com", postcode: "OL4 6WF"  }
    ]
});

如果我将组织负责人伊丽莎白·霍顿 (Elizabeth Horton) 的顺序更改为数据源的底部，如下所示:

$('#people').getOrgChart({
    theme: "vivian",
    primaryColumns: ["name", "title", "phone", "mail", "postcode"],
    imageColumn: "image",
    gridView: true,
    dataSource:[            
        { id: 2, parentId: 1, name: "Emily Horton", title: "Fork lift operator", phone: "(08) 9015 4407", image: "images/f-45.jpg", mail:"emily.horton@live.com", postcode: "BA5 0AP"  },
        { id: 3, parentId: 1, name: "Robert Nolan", title: "Blockmason", phone: "(02) 6747 7998", image: "images/f-41.jpg", mail:"robert.nolan@live.com", postcode: "BH9 4NG"  },
        { id: 4, parentId: 1, name: "Callum Anderson", title: "System operator", phone: "(03) 5314 0473", image: "images/f-43.jpg", mail:"callum.anderson@live.com", postcode: "HR6 8ZF"  },
        { id: 5, parentId: 4, name: "Courtney John", title: "System operator", phone: "(03) 5314 0473", image: "images/f-42.jpg", mail:"courtney.john@live.com", postcode: "OL4 6WF"  },
        { id: 1, parentId: null, name: "Elizabeth Horton", title: "Founder", phone: "(03) 9252 4642" , image: "images/f-46.jpg", mail:"elizabeth.horton@live.com", postcode: "PH2 2SR" }
    ]
});

我收到此错误:

Uncaught TypeError: Cannot read property '_aZ' of null

所以我希望回答我自己的问题可以帮助其他有同样问题的人。

干杯!
