前端利用bpmn-js实现工作流

# bpmn-js (pre-packaged version) This is a packaged version of [bpmn-js](https://github.com/bpmn-io/bpmn-js) for standalone usage or via [bower](http://bower.io). ## Usage Download individual files from the [dist folder](https://github.com/bpmn-io/bower-bpmn-js/tree/master/dist) or fetch them with dependencies via `bower install bpmn-js`. Include the file(s) into your project ```html <!-- bpmn-js viewer --> <script src="bower_components/bpmn-js/dist/bpmn-viewer.js"></script> <!-- or --> <!-- bpmn-js modeler --> <script src="bower_components/bpmn-js/dist/bpmn-modeler.js"></script> <script> // bundle exposes the viewer / modeler via the BpmnJS variable var BpmnViewer = window.BpmnJS; var xml; // ADD BPMN 2.0 XML HERE var viewer = new BpmnViewer({ container: 'body' }); viewer.importXML(xml, function(err) { if (err) { console.log('error rendering', err); } else { console.log('rendered'); } }); </script> ``` Checkout the [examples repository](https://github.com/bpmn-io/bpmn-js-examples) for a complete example of [how to use bpmn-js with bower](https://github.com/bpmn-io/bpmn-js-examples/tree/master/simple-bower). ## License Use under the terms of the [bpmn-js license](http://bpmn.io/license).
