我一直在研究几个免费的组织结构图库。我尝试了一些:orgchart(由 dabeng)、d3-mitch-tree 和 Treant.js。我成功地在我的 React 应用程序中使用了前两个,尽管只是用于基本用途。
我只是努力对 Treant.js 做同样的事情。这不是直截了当的。在解决 Treant.js 的问题之前,我必须快速了解 CommonJs。
浏览了它的源代码,我看到它使用了 CommonJs 模块系统,所以它的 javascript 模块必须使用 require 语句来包含,而不是 import 声明。你可以在下面看到我的代码。
但是,当运行应用程序时,它显示错误:
“未定义拉斐尔”
在调试的时候,我找到了错误的原因。 Treant.js 文件依赖于 raphael 库,该库用于其 handleOverflow 函数。所以我在 Treant.js 文件的那个函数中添加了一行来包含如下依赖:
// Create Raphael instance, set scrollbars if necessary
handleOverflow: function(treeWidth, treeHeight) {
// I added this statement which didn't exist in original file
var Raphael = require("./vendor/raphael")
// ...
这是我的代码:
import React from "react";
import "treant-js/Treant.css"
import "treant-js/basic-example.css"
var Treant = require("treant-js/Treant")
export default class MyTreantJs extends React.Component {
constructor(props) {
super(props);
this.treant = null
this.chart_config = null
}
componentDidMount() {
const loginpathname = window.sessionStorage.getItem("appHomePathName", homepathname)
const index = loginpathname.indexOf("public")
const homepathname = loginpathname.substring(0,index)
const imageurl = homepathname + "/public/images/headshots/"
const config = {
container: "#basic-example",
connectors: {
type: 'step'
},
node: {
HTMLclass: 'nodeExample1'
}
},
ceo = {

];
this.treant = new Treant(this.chart_config)
}
render(){
return (
<div id="basic-example" style={{height:"600px", width:"1200px"}}></div>
);
}
}
这里,basic-example.css 文件是从示例文件夹中复制而来的。
图表的配置也取自示例文件夹。我使用浏览器的 sessionStorage 来查找图像的位置。
到目前为止,我的代码运行良好。
编辑:
上面的代码仍然不起作用。 请勿修改 Treant.js 源代码。相反,请使用以下内容:
import React from "react";
import "treant-js/Treant.css"
import "treant-js/examples/basic-example/basic-example.css"
import Raphael from "raphael";
window.Raphael = Raphael
var Treant = require("treant-js/Treant")
Treant = Treant.Treant
Treant 不导入 raphael,但它希望 raphael 实例在全球范围内可用。这就是为什么在我们的应用程序中导入 raphael 后,我们需要以下语句:
window.Raphael = Raphael
注意声明:
Treant = Treant.Treant
这是必要的,因为 Treant(在查看控制台时)是一个具有属性的对象,也名为 Treant。
