集成BPMN-JS來Modeler中的反應成分

Question

我一直在努力的bpmn-js modeler的反應成分結合，但一直未能得到任何結果。任何人都可以幫助我的代碼？所有的要求已經完成。這對我很有幫助。由於

Answer 1

我創建誰加載庫似乎工作確定一小部分，也許你一直在嘗試它不使用陣營生命週期來實現，是非常重要的知道這個工作如何實現大部分的結果庫使用DOM元素，該元素是唯一可用的渲染後，所以我用componentDidMount保證。

這裏是基本的演示： https://www.webpackbin.com/bins/-KnHgXtsXlkcJJo735S4

組件例如：

import React from 'react' 
import BpmnViewer from 'bpmn-js' 

class bpmnView extends React.Component{ 
    constructor(){ 
    super(); 
    this.viewer = new BpmnViewer(); 
    this.generateId = 'bpmnContainer'+ Date.now(); 
    } 
    render(){ 
    return <div id={this.generateId}></div>; 
    } 
    componentDidMount(){ 
    this.viewer.attachTo('#'+ this.generateId); 

     // import function 
    function importXML(xml,Viewer) { 

    // import diagram 
    Viewer.importXML(xml, function(err) { 

     if (err) { 
     return console.error('could not import BPMN 2.0 diagram', err); 
     } 

     var canvas = Viewer.get('canvas'), 
      overlays = Viewer.get('overlays'); 


     // zoom to fit full viewport 
     canvas.zoom('fit-viewport'); 

     // attach an overlay to a node 
     overlays.add('SCAN_OK', 'note', { 
     position: { 
      bottom: 0, 
      right: 0 
     }, 
     html: '<div class="diagram-note">Mixed up the labels?</div>' 
     }); 

     // add marker 
     canvas.addMarker('SCAN_OK', 'needs-discussion'); 
    }); 
    } 


    // a diagram to display 
    // 
    // see index-async.js on how to load the diagram asynchronously from a url. 
    // (requires a running webserver) 
    var diagramXML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<definitions xmlns=\"http://www.omg.org/spec/BPMN/20100524/MODEL\"\r\n
