使用npm安装bpmn.js
npm install --save bpmn-js
vue使用bpmn
在main.js中引入样式
import 'bpmn-js/dist/assets/diagram-js.css'
import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css'
vue页面引入并使用bpmn
<template>
<div class="bpmn">
<div id="container" style="height:800px"></div>
</div>
</template>
<script>
import BpmnModeler from 'bpmn-js/lib/Modeler'
export default {
name: 'Bpmn',
data () {
return {
bpmnModeler: null
}
},
mounted () {
this.initData()
},
methods: {
initData () {
const container = document.getElementById('container')
this.bpmnModeler = new BpmnModeler({
container: container
})
this.bpmnModeler.createDiagram(() => {
this.bpmnModeler.get('canvas').zoom('fit-viewport')
})
}
}
}
</script>
运行结果
保存bpmn为xml
handleSave () {
this.bpmnModeler.saveXML({ format: true }).then(res => {
localStorage.setItem('bpmnModelerXML', JSON.stringify(res))
})
}
