EasyUI combotree 使用技巧

 

 

$('#areaName').combotree({
            url: '../Ajax/Common.ashx?Method=GetCombotreeData',
            multiple: true,
            checkbox: true,
            isShowPic: false,
            onCheck: function (node, checked) {
                //   MainJs.RemoveNodeAll('areaName');
            },
            onLoadSuccess: function (node, data) {
                var rootNode = data[0];//第一个节点
                if (rootNode) {
                    var t = $('#areaName').combotree('tree'); // 获取树对象
                    var node1=t.tree('find', rootNode.id);
                    t.tree("uncheck", node1.target); //取消所有的选中
                }
            }
        });

默认选中根节点的方法

 onLoadSuccess: function (node, data) {
                var t = $('#WAY_JY').combotree('tree'); // 获取树对象
                var rootNode = t.tree('getRoot');//基础节点
                //var node1 = t.tree('find', rootNode.id);
                t.tree("uncheck", rootNode.target); //取消所有的选中
            }

 json格式

[
  {
    "id": 1,
    "text": "My Documents",
    "children": [
      {
        "id": 11,
        "text": "Photos",
        "state": "closed",
        "children": [
          {

            "checked": true
          }
