Design BPMN 2.0 modeler in a Vue.js application based on bpmn-js.
yarn add vue-bpmn-modeler
# main.js
import VueBpmnModeler from "vue-bpmn-modeler";
Vue.use(VueBpmnModeler);
# yourPage.vue
<style lang="less">
@import "~vue-bpmn-modeler/lib/vue-bpmn-modeler.css";
</style>
组件会显示设计器,参数 v-model="modeler",会通过画图操作实时返回对应的xml数据和svg数据,用于保存初始化的模板。
<template>
<BpmnModeler v-model="modeler"></BpmnModeler>
</template>
<script>
export default {
name: "BpmnModeler",
props: {
diagramXML: String
},
watch: {
diagramXML(val) {
this.openDiagram(val)
}
},
data() {
modeler: {
// 模型xml数据
// model xml data
xmlData: "",
// svg图片数据
// svg data
svgImage: ""
}
},
// 详细代码请参考源码
// see source code for detail
mounted() {
},
methods: {
openDiagram(xml) {
if (xml) {
this.modeler.importXML(xml, function(err) {
if (err) {
console.error(err);
} else {
}
});
this.xmlData = xml;
} else {
this.modeler.createDiagram();
let _self = this;
setTimeout(() => {
/**
* 修改xml属性值 isExecutable = false => true
* isExecutable = false 后端部署流程时 不会创建流程定义数据
*/
let modelerCanvas = _self.modeler.get("canvas");
let rootElement = modelerCanvas.getRootElement();
let modeling = _self.modeler.get("modeling");
// modeling.updateProperties(rootElement, {
// // isExecutable: true
// });
// 设定开始节点名称和结束节点名称
// set StartEvent name 'start' and EndEvent name 'end'
rootElement.children.forEach(n => {
if (n.type === 'bpmn:StartEvent') {
modeling.updateProperties(n, {
name: '开始',
});
} else if (n.type === 'bpmn:EndEvent') {
modeling.updateProperties(n, {
name: '结束',
});
}
})
});
}
}
}
};
</script>
When the process starts, the process will complete first task by default, and the TODO tasks will be orange.
when the first task completed and met condition 1, the process coming to 'costcenter' task, Completed tasks displayed in green.
参数介绍: xmlData: 表示流程图的xml数据 taskList: 表示流程的历史记录 可以通过服务的接口 historyService 获得
<template>
<BpmnViewer :xmlData="xmlData" :taskData="taskList"></BpmnViewer>
</template>
<script>
export default {

modeler: {
// 模型xml数据
xmlData: "",
// 任务列表
taskList: [{
// 任务定义的key

}]
}

}
this.$refs.modeler.replace(addOrReplace).then((taskList) => {
// new task list, incluce taskId
console.log(taskList);
