机构懒加载,选人时候,如果该机构下面没人,就取消加载并且不显示箭头
<a-tree checkable :load-data="onloadData" @check="onCheck" :tree-data="treeData" :replace-fields="replaceFields" :loadedKeys="loadedKeys" :expandedKeys="expandedKeys" @expand="onExpand" >
//异步加载数据 onloadData(treeNode) { return new Promise((resolve,reject)=>{ let taskId = treeNode.dataRef.id; if (treeNode.dataRef.meta == 1) { taskId = taskId ? taskId.substr(2, taskId.length) : ""; console.log(‘treeNode.dataRef.children‘, treeNode); commonApi.subOrgAndUserTreeNode(taskId).then((data) => { if (data.length > 1) { treeNode.dataRef.children.splice(0,treeNode.dataRef.children.length) treeNode.dataRef.children = data; this.treeData = [...this.treeData]; } else { treeNode.dataRef.isLeaf = true; this.treeData = [...this.treeData]; } }).finally(() => { resolve() }); } else { resolve(); return; } })
