我正在尝试在 React Js 中为 NLP/POS-tagger 项目创建一个解析器树。我发现 GoJs 提供了一个很酷的解析器树 GoJs-parser-tree ,但我找不到 React js 实现的文档。我尝试了一些示例,但我无法将它与 react 一起使用 这是我需要在 react 中使用它的代码

<h3>GoJS Parse Tree</h3>
<div id="myDiagramDiv" style="border: solid 1px black; width:100%; height:500px"></div>
<p>A <em>parse tree</em> is an ordered, rooted tree representing the structure of a sentence, broken down to parts-of-speech.</p>
<p>
This diagram uses a custom <a>TreeLayout</a> called <b>FlatTreeLayout</b> that places all leaf nodes at the same Y position.
It also makes use of a <b>TreeExpanderButton</b> on the node template. See the <a href="../intro/buttons.html">Intro page on Buttons</a> for more GoJS button information.
</p>
<p>
The abbreviations used in this diagram are:
<ul>
<li><b>NP</b>, a noun phrase</li>
<li><b>VP</b>, a verb phrase</li>
<li><b>PP</b>, a prepositional phrase</li>
<li><b>DT</b>, a determiner</li>
<li><b>JJ</b>, an adjective</li>
<li><b>NN</b>, a common noun</li>
<li><b>VBZ</b>, a third person singular present verb</li>
<li><b>VBN</b>, a past participle verb</li>
</ul>

这是我在尝试使用它时得到的代码 react
import React, {Component} from 'react';
import go from 'gojs';
const goObj = go.GraphObject.make;
export default class GoJs extends Component {
constructor (props) {
super (props);
this.renderCanvas = this.renderCanvas.bind (this);
this.state = {myModel: null, myDiagram: null}
}
renderCanvas () {
let model = goObj (go.TreeModel);
let diagram = goObj (go.Diagram, this.refs.goJsDiv, {initialContentAlignment: go.Spot.Center});
this.setState({myModel: model, myDiagram: diagram},
() => {
model.nodeDataArray = this.props.data;
diagram.model = model;
this.setState({myModel: model, myDiagram: diagram});
}
);
}
componentDidMount () {
this.renderCanvas ();
}
componentWillUpdate (prevProps) {
if (this.props.data !== prevProps.data) {
console.log ('Updating');
const model = this.state.myModel;
const diagram = this.state.myDiagram;
model.nodeDataArray = this.props.data;
diagram.model = model;
this.setState({myModel: model, myDiagram: diagram});
}
}
render () {
return <div ref="goJsDiv" style={{'width': '500px', 'height': '500px', 'backgroundColor': '#DAE4E4'}}></div>;
}
}
GoJs.propTypes = { data: React.PropTypes.string.isRequired };
GoJs.defaultProps = { data: '[]' };
我无法弄清楚缺少什么,我从中得到的结果一团糟。
最佳答案
在花了几个小时在这里和那里更改代码之后,我设法将这里需要的东西变成了我的最终代码

this.state = {myModel: null, myDiagram: null}
}
renderCanvas () {
function FlatTreeLayout () {
go.TreeLayout.call(this); // call base constructor
}
go.Diagram.inherit(FlatTreeLayout, go.TreeLayout);
// This assumes the TreeLayout.angle is 90 -- growing downward
/** @override */
FlatTreeLayout.prototype.commitLayout = function () {
go.TreeLayout.prototype.commitLayout.call(this); // call base method first
// find maximum Y position of all Nodes
var y = -Infinity;
this.network.vertexes.each(function(v) {
y = Math.max(y, v.node.position.y);
});
// move down all leaf nodes to that Y position, but keeping their X position
this.network.vertexes.each(function(v) {
var node = v.node;
if (node.isTreeLeaf) {
node.position = new go.Point(node.position.x, y);
}
});
};
let model = goObj (go.TreeModel);
let diagram = goObj (go.Diagram, this.refs.goJsDiv, {
allowCopy: false,
allowDelete: false,
allowMove: false,
initialContentAlignment: go.Spot.Center,
initialAutoScale: go.Diagram.Uniform,
layout:
goObj(FlatTreeLayout, // custom Layout, defined below
{ angle: 90,
compaction: go.TreeLayout.CompactionNone }),
"undoManager.isEnabled": true
});
diagram.nodeTemplate = goObj(go.Node, "Vertical",
{ selectionObjectName: "BODY" },
goObj(go.Panel, "Auto", { name: "BODY" },
goObj(go.Shape, "RoundedRectangle",
new go.Binding("fill"),
new go.Binding("stroke")),
goObj(go.TextBlock,
{ font: "bold 12pt Arial, sans-serif", margin: new go.Margin(4, 2, 2, 2) },
new go.Binding("text"))
),
goObj(go.Panel, // this is underneath the "BODY"
{ height: 15 }, // always this height, even if the TreeExpanderButton is not visible
goObj("TreeExpanderButton")
)
);
diagram.linkTemplate = goObj(go.Link,goObj(go.Shape, { strokeWidth: 1.5 }));
this.setState({myModel: model, myDiagram: diagram},
() => {
model.nodeDataArray = this.props.data;
diagram.model = model;
this.setState({myModel: model, myDiagram: diagram});
}
);
}
componentDidMount () {
this.renderCanvas ();
}
componentWillUpdate (prevProps) {
if (this.props.data !== prevProps.data) {
console.log ('Updating');
const model = this.state.myModel;
const diagram = this.state.myDiagram;
model.nodeDataArray = this.props.data;
diagram.model = model;
this.setState({myModel: model, myDiagram: diagram});
}
}
render () {
return <div ref="goJsDiv" style={{'width': '500px', 'height': '500px', 'backgroundColor': '#DAE4E4'}}></div>;
}
}
GoJs.propTypes = { data: React.PropTypes.string.isRequired };
GoJs.defaultProps = { data: '[]' };
由于它是一个哑(无状态)组件,我们必须通过 props 从父组件传递数据。
来自父组件
render(){
return(
<div>
<PTagBox data={nodeDataArray}/>
</div>
);
}
其中 PTagBox 是dumb组件或子组件
