[Vue-Treeselect Warning] Unloaded branch node detected. “loadOptions” prop is required to load its children

Vue-Treeselect中返回的数据中child为null，所有需要将为null的删除

    getOfficeTree() {
    
    
        this.treeData = [res.data];
        this.getTreeName(this.treeData)
    },
    getTreeName(list) {
    
    
      let _this = this;
      list.forEach((item, index) => {
    
    
        let a = item;
        if (index < list.length) {
    
    
          if (a.child == null) {
    
    
            delete a.child
          }
        }
        if (a.child && a.child.length > 0) {
    
    
          if (a.child && a.child.length > 0) {
    
    
            _this.getTreeName(a.child);
          }
        }
      });
      return;
    },

最终this.treeData的值将改变：去掉的所有child:null
