Question

我正在http://www.getorgchart.com

尝试使用此组织结构图库

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，很少有节点可以完美运行，我得到此控制台错误：

未捕获的TypeError：无法读取null的属性'_aZ'

无法显示图表。

任何帮助都会被贬低。谢谢！

经过一番研究，我已经解决了这个问题。

问题是您需要先由父母订购您的dataSource（文档中未说明）;让我们在 在客户端上初始化 在线演示中查看此示例：


    $('#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 Elizabeth Horton 的顺序更改为dataSource的底部，如：


$('#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" }
    ]
});

我收到了这个错误：

未捕获的TypeError：无法读取属性＆＃39; _aZ＆＃39;为null

所以我希望回答我自己的问题可以帮助其他人解决同样的问题。

干杯！

除了在子女之前定义父母之外，如果您不想手动修改1100人JSON数据结构中的id和parentId值，您还需要对{{1 }}：

由此：

getorgchart.js

对此：

getOrgChart.prototype.loadFromJSON = function(c) {
    this._aB = [];
    this._a9 = 0;
    this._a8 = 0;
    this._au = [];
    this._aj = [];
    this._aO = [];
    this._a7 = new getOrgChart.person(-1, null, null, 2, 2);
    for (var a = 0; a < c.length; a++) {
        var e = c[a];
        var b = e[Object.keys(e)[0]];
        var d = e[Object.keys(e)[1]];
        delete e[Object.keys(e)[0]];
        delete e[Object.keys(e)[0]];
        this.createPerson(b, d, e)
    }
    this.draw()
};

getOrgChart.prototype.loadFromJSON = function(c) { this._aB = []; this._a9 = 0; this._a8 = 0; this._au = []; this._aj = []; this._aO = []; this._a7 = new getOrgChart.person(-1, null, null, 2, 2); for (var a = 0; a < c.length; a++) { var e = c[a]; var b = e['id']; var d = e['parentId']; delete e['id']; delete e['parentId']; this.createPerson(b, d, e) } this.draw() };和Object.keys(e)[0]假设Object.keys(e)[1]和id是“人物”对象中的前两个键，如果您没有先定义它们，则不会实际上是真的。

将代码更新为以下内容可让您在初始化之前动态生成parentId参数。
