bpmn-js（五）线条上添加决策表达式bpmn-js确实强⼤，但资料也确实太少。可能也只有作者知道咋玩，为了给线条加上表达式这么个功能 ⽣⽣的看了2天源码才搞定。 const moddle = deler._moddle; var conditionExpression = ('bpmn:FormalExpression', { body: ion });const modeling = ("modeling");Properties(t, { conditionExpression: conditionExpression });最终xml效果如下： 22222 confirmSelModule() { let condition = this.$dition(); if(ion==null){ this.$set(ckNode,'condition',condition) }else{ ion = condition; } st = this.$cList(); let list=[] if(ng!==null){ list=[...ng]; } const data={id:,name:,decision:on,defaultNode:tNode,list:list}; this.$($M('SET_GATEWAY_LIST','appIssueStore'),data); g = false; const moddle = deler._moddle; var conditionExpression = ('bpmn:FormalExpression', { body: condition }); const modeling = ("modeling"); Properties(ckNode, { conditionExpression: conditionExpression }); },记录下，免得下次忘了。
