jQuery中如何使用工作流程图bpmn-js.js 初始化、预览

 先上效果图

 

 

流程图设计：Modeler

<link rel="stylesheet" href="https://unpkg.com/bpmn-js@7.2.0/dist/assets/diagram-js.css" />
<link rel="stylesheet" href="https://unpkg.com/bpmn-js@7.2.0/dist/assets/bpmn-font/css/bpmn.css" />

<script src="https://unpkg.com/bpmn-js@7.2.0/dist/bpmn-modeler.development.js"></script>

使用流程图控件设计流程图

 1 <div id="canvas"> </div>
 2 <script>
 3     $(function(){
 4         var BpmnModeler = window.BpmnJS;
 5         var xml = "<?xml version='1.0' encoding='UTF-8'?><definitions xmlns='http://www.omg.org/spec/BPMN/20100524/MODEL' xmlns:bpmndi='http://www.omg.org/spec/BPMN/20100524/DI' xmlns:omgdi='http://www.omg.org/spec/DD/20100524/DI' xmlns:omgdc='http://www.omg.org/spec/DD/20100524/DC' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' id='sid-38422fae-e03e-43a3-bef4-bd33b32041b2' targetNamespace='http://bpmn.io/bpmn' exporter='bpmn-js (https://demo.bpmn.io)' exporterVersion='5.1.2'><process id='Process_1' isExecutable='false'><startEvent id='StartEvent_1y45yut' name='开始'><outgoing>SequenceFlow_0h21x7r</outgoing></startEvent><task id='Task_1hcentk' name='审批'><incoming>SequenceFlow_0h21x7r</incoming><outgoing>SequenceFlow_06o0wf0</outgoing></task><sequenceFlow id='SequenceFlow_0h21x7r' sourceRef='StartEvent_1y45yut' targetRef='Task_1hcentk' /><task id='Task_13intos' fill='red' name='下一节点'><incoming>SequenceFlow_06o0wf0</incoming><outgoing>SequenceFlow_1oydyx4</outgoing></task><sequenceFlow id='SequenceFlow_06o0wf0' sourceRef='Task_1hcentk' targetRef='Task_13intos' /><endEvent id='EndEvent_0aot3cz' name='结束'><incoming>SequenceFlow_1oydyx4</incoming></endEvent><sequenceFlow id='SequenceFlow_1oydyx4' sourceRef='Task_13intos' targetRef='EndEvent_0aot3cz' /></process><bpmndi:BPMNDiagram id='BpmnDiagram_1'><bpmndi:BPMNPlane id='BpmnPlane_1' bpmnElement='Process_1'><bpmndi:BPMNShape id='StartEvent_1y45yut_di' bpmnElement='StartEvent_1y45yut'><omgdc:Bounds x='152' y='102' width='36' height='36' /><bpmndi:BPMNLabel><omgdc:Bounds x='160' y='145' width='22' height='14' /></bpmndi:BPMNLabel></bpmndi:BPMNShape><bpmndi:BPMNShape id='Task_1hcentk_di' bpmnElement='Task_1hcentk'><omgdc:Bounds x='240' y='80' width='100' height='80' /></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_0h21x7r_di' bpmnElement='SequenceFlow_0h21x7r'><omgdi:waypoint x='188' y='120' /><omgdi:waypoint x='240' y='120' /></bpmndi:BPMNEdge><bpmndi:BPMNShape id='Task_13intos_di' bpmnElement='Task_13intos'><omgdc:Bounds x='400' y='80' width='100' height='80' /></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_06o0wf0_di' bpmnElement='SequenceFlow_06o0wf0'><omgdi:waypoint x='340' y='120' /><omgdi:waypoint x='400' y='120' /></bpmndi:BPMNEdge><bpmndi:BPMNShape id='EndEvent_0aot3cz_di' bpmnElement='EndEvent_0aot3cz'><omgdc:Bounds x='562' y='102' width='36' height='36' /><bpmndi:BPMNLabel><omgdc:Bounds x='569' y='145' width='22' height='14' /></bpmndi:BPMNLabel></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_1oydyx4_di' bpmnElement='SequenceFlow_1oydyx4'><omgdi:waypoint x='500' y='120' /><omgdi:waypoint x='562' y='120' /></bpmndi:BPMNEdge></bpmndi:BPMNPlane></bpmndi:BPMNDiagram></definitions>"; // ADD BPMN 2.0 XML HERE
 6         var modeler = new BpmnModeler({
 7             container: '#canvas'
 8         });
 9         modeler.importXML(xml, function(err) {
10             if (err) {
11                 console.log('error rendering', err);
12             } else {
13                 console.log('rendered');
14             }
15         });
16     });
17 </script>

 

流程图预览：Viewer

<link rel="stylesheet" href="https://unpkg.com/bpmn-js@7.2.0/dist/assets/diagram-js.css" />
<link rel="stylesheet" href="https://unpkg.com/bpmn-js@7.2.0/dist/assets/bpmn-font/css/bpmn.css" />

<script src="https://unpkg.com/bpmn-js@7.2.0/dist/bpmn-viewer.development.js"></script>

使用流程图控件预览流程图

<div id="viewer"> </div>
<script>
    $(function(){
        var BpmnViewer = window.BpmnJS;
        var xml = "<?xml version='1.0' encoding='UTF-8'?><definitions xmlns='http://www.omg.org/spec/BPMN/20100524/MODEL' xmlns:bpmndi='http://www.omg.org/spec/BPMN/20100524/DI' xmlns:omgdi='http://www.omg.org/spec/DD/20100524/DI' xmlns:omgdc='http://www.omg.org/spec/DD/20100524/DC' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' id='sid-38422fae-e03e-43a3-bef4-bd33b32041b2' targetNamespace='http://bpmn.io/bpmn' exporter='bpmn-js (https://demo.bpmn.io)' exporterVersion='5.1.2'><process id='Process_1' isExecutable='false'><startEvent id='StartEvent_1y45yut' name='开始'><outgoing>SequenceFlow_0h21x7r</outgoing></startEvent><task id='Task_1hcentk' name='审批'><incoming>SequenceFlow_0h21x7r</incoming><outgoing>SequenceFlow_06o0wf0</outgoing></task><sequenceFlow id='SequenceFlow_0h21x7r' sourceRef='StartEvent_1y45yut' targetRef='Task_1hcentk' /><task id='Task_13intos' fill='red' name='下一节点'><incoming>SequenceFlow_06o0wf0</incoming><outgoing>SequenceFlow_1oydyx4</outgoing></task><sequenceFlow id='SequenceFlow_06o0wf0' sourceRef='Task_1hcentk' targetRef='Task_13intos' /><endEvent id='EndEvent_0aot3cz' name='结束'><incoming>SequenceFlow_1oydyx4</incoming></endEvent><sequenceFlow id='SequenceFlow_1oydyx4' sourceRef='Task_13intos' targetRef='EndEvent_0aot3cz' /></process><bpmndi:BPMNDiagram id='BpmnDiagram_1'><bpmndi:BPMNPlane id='BpmnPlane_1' bpmnElement='Process_1'><bpmndi:BPMNShape id='StartEvent_1y45yut_di' bpmnElement='StartEvent_1y45yut'><omgdc:Bounds x='152' y='102' width='36' height='36' /><bpmndi:BPMNLabel><omgdc:Bounds x='160' y='145' width='22' height='14' /></bpmndi:BPMNLabel></bpmndi:BPMNShape><bpmndi:BPMNShape id='Task_1hcentk_di' bpmnElement='Task_1hcentk'><omgdc:Bounds x='240' y='80' width='100' height='80' /></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_0h21x7r_di' bpmnElement='SequenceFlow_0h21x7r'><omgdi:waypoint x='188' y='120' /><omgdi:waypoint x='240' y='120' /></bpmndi:BPMNEdge><bpmndi:BPMNShape id='Task_13intos_di' bpmnElement='Task_13intos'><omgdc:Bounds x='400' y='80' width='100' height='80' /></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_06o0wf0_di' bpmnElement='SequenceFlow_06o0wf0'><omgdi:waypoint x='340' y='120' /><omgdi:waypoint x='400' y='120' /></bpmndi:BPMNEdge><bpmndi:BPMNShape id='EndEvent_0aot3cz_di' bpmnElement='EndEvent_0aot3cz'><omgdc:Bounds x='562' y='102' width='36' height='36' /><bpmndi:BPMNLabel><omgdc:Bounds x='569' y='145' width='22' height='14' /></bpmndi:BPMNLabel></bpmndi:BPMNShape><bpmndi:BPMNEdge id='SequenceFlow_1oydyx4_di' bpmnElement='SequenceFlow_1oydyx4'><omgdi:waypoint x='500' y='120' /><omgdi:waypoint x='562' y='120' /></bpmndi:BPMNEdge></bpmndi:BPMNPlane></bpmndi:BPMNDiagram></definitions>"; // ADD BPMN 2.0 XML HERE
        var viewer = new BpmnViewer({
            container: '#viewer'
        });
        viewer.importXML(xml, function(err) {
            if (err) {
                console.log('error rendering', err);
            } else {
                console.log('rendered');
            }
        });
    });
</script>

 

注意：xml为流程图设计好后保存的xml。
