jquery中EasyUI实现同步树

在JS中,将显示树的url地址写成control的地址即可.

control:

 @RequestMapping(value = "/tree")

 public void tree(HttpServletRequest request, HttpServletResponse response) throws IOException {

  this.writeJson(response, bookService.getTree());

 }

dao:

 /**

  * 获取树

  */

 @Override

 public List<Tree> getTree(){

  try {

   List<Tree> trees = new ArrayList<Tree>();

   List<TBookType> root = this.search(0);

   if(root != null && root.size() > 0){

    for(TBookType tb : root){

     Tree rootnode = this.getNode(tb);

     rootnode.setState("open");

     trees.add(rootnode);

    }

   }

   return trees;

  } catch (Exception e) {

   e.printStackTrace();

   return null;

  }

 }

 /**

  * 递归

  */

 private Tree getNode(TBookType node){

  if(node == null){

   return null;

  }

  try {

   Tree treenode = new Tree();

   treenode.setId(String.valueOf(node.getId()));

   treenode.setText(node.getName());

   treenode.setPid(String.valueOf(node.getPid()));

   List<TBookType> children = this.search(node.getId());

   if(children != null && children.size() > 0){

    treenode.setState("closed");

    for(TBookType child : children){

     Tree childnode = this.getNode(child);

     if(childnode != null){

      treenode.getChildren().add(childnode);//递归

     }

    }

   }

   return treenode;

  } catch (Exception e) {

   throw new BusinessException("获取数据出错!", e);

  }

 }

以上就是使用EasyUI实现同步树的全部核心代码了，希望大家能够喜欢。
