如何检测节点何时离开组？ JqTree

时间：2015-08-11 13:51:52

标签： javascript jquery jqtree

我已经获得了这棵树，每次将节点移动到另一个节点时，我都会发送id child及其parent's，但我＆＃39 ; d还想检测孩子何时被移到父母之外。

在firebug上查看

澄清：

例如，我有两个节点：

  

node1（无父对象）

     

node2（无父对象）

然后，我在node1 中移动node2：

（然后我使用：if (event.move_info.position == 'inside');）

检查位置
  

node2（无父对象）

     
    

node（node2）

  

我还想检查我将node1移到node2之外的时间：

但没有 event.move_info.position == 'outside'

发件人：

  

node2（无父对象）

     
    

节点（node2）

  

以

  

node1（无父对象）
  node2（无父对象）

你可以开导我吗？

提前致谢。

答案 0 :(得分：0)

在不知疲倦地工作之后，我终于弄明白了，它有效，有一套4 if s 

$(document).ready(function() {

  //Mandar o response aqui no data
  var data = [{
    label: '1',
    id: 1,
    children: [{
      label: '2',
      id: 2
    }, {
      label: '3',
      id: 3
    }]
  }, {
    label: '4',
    id: 4,
    children: [{
      label: '5',
      id: 5
    }]

  }];



  $('#tree1').tree({
    data: data,
    autoOpen: false,
    dragAndDrop: true
  });

  console.log("Original Structure" + $('#tree1').tree('toJson'));

  $('#tree1').bind(
    'tree.move',
    function(event) {
      console.log('______________________________________');
      console.log('moved_node', event.move_info.moved_node.id);
      console.log('target_node', event.move_info.target_node.id);
      console.log('position', event.move_info.position);
      console.log('previous_parent', event.move_info.previous_parent.id);
      console.log('___');
      console.log("target's parent", event.move_info.target_node.parent.id);

      var myNode = event.move_info.moved_node.id;
      var target = event.move_info.target_node.id;
      var myXDad = event.move_info.previous_parent.id;
      var targetsDad = event.move_info.target_node.parent.id;

      if (event.move_info.position == 'after') {

        if (target === myXDad) {
          if (targetsDad === undefined) {
            var family = ('vpai=' + 0 + '&vfilho=' + myNode);
            alert(family);
            send(family);
          } else {
            //get your target's dad as your dad
            var family = ('vpai=' + targetsDad + '&vfilho=' + myNode);
            alert(family);
            send(family);
          }
        } else if (!(myXDad === targetsDad)) {
          //get target's dad as your dad
          var family = ('vpai=' + 0 + '&vfilho=' + myNode);
          alert(family);
          send(family);
        }

      }

      if (event.move_info.position == 'inside') {
        var family = ('vpai=' + event.move_info.target_node.id + '&vfilho=' + event.move_info.moved_node.id)
        alert(family);
        send(family);
      }

      function send(family) {
        $.ajax({
          type: 'POST',
          url: 'sistema.agrosys.com.br',
          data: family,
          success: function(data, textStatus) {
            console.log('DONE: Request has been successfully sent');
          },
          error: function(xhr, textStatus, errorThrown) {
            alert('Envio Falhou\n\nERR: ' + errorThrown);
          }
        });
      }



    }
  );
