{
    echoJson(GetDepts(Constants.OptionAllVal, dropListService.GetDepts(LoginUser)));
}

/// <summary>
/// 获取部门树

private List<Dictionary<string, object>> GetDepts(int parentDeptId, List<IMP_Dept> allDeptList)
{
    List<Dictionary<string, object>> dicList = new List<Dictionary<string, object>>();

    List<IMP_Dept> deptList = allDeptList.FindAll(a => a.PId == parentDeptId);
    if (deptList.Count == 0 && parentDeptId != Constants.OptionAllVal) return null;

    foreach (IMP_Dept dept in deptList)
    {
        Dictionary<string, object> dic = new Dictionary<string, object>();
        dic.Add("id", dept.Id);
        dic.Add("text", dept.Name);
        dic.Add("checkbox", true);

        List<Dictionary<string, object>> childDicList = new List<Dictionary<string, object>>();

        //当前部门下的子部门
        List<Dictionary<string, object>> childDeptDicList = GetDepts(dept.Id, allDeptList);
        if (childDeptDicList != null)
        {
            childDicList.AddRange(childDeptDicList);
        }

        //当前部门下的员工
        List<Dictionary<string, object>> childEmployeeDicList = GetEmployees(dept);
        if (childEmployeeDicList != null)
        {
            childDicList.AddRange(childEmployeeDicList);
        }

        if (childDicList != null)
        {
            dic.Add("state", parentDeptId == Constants.OptionAllVal ? "open" : "closed");
            dic.Add("children", childDicList);

}

        dic.Add("attributes", attributes);
        dicList.Add(dic);
    }

    return dicList;
}

二、HTML代码

三、JS代码

 

一、引用CSS和JS

<link href="~js/easyui/easyui.css" rel="stylesheet" type="text/css" />
<script src="~js/easyui/jquery.easyui.min.js" type="text/javascript"></script>
<input type="text" id="subject" name="subject">

 

$('#dept').combotree({
    url: '#{GetDeptTree}',
    required: false,
    onSelect: function (node) {
        $.ajax({
            type: "POST",
            url: "#{GetJobs}",
            data: "deptId=" + node.id,
            success: function (data) {
                $("#job").html(data);
            }
        });
    }
});

$('#dept').combotree('setValue', "#{employmentNeeds.Dept.Id}");

 

叁 、后台代码:

//部门员工树
$('#Employee').combotree({
    url: '#{GetEmployees}',
    required: false,
    onSelect: function (node) {
        //控制只能选叶子节点
        //返回树对象  
        var tree = $(this).tree;
        //选中的节点是否为叶子节点,如果不是叶子节点,清除选中  
        var isLeaf = tree('isLeaf', node.target);
        if (!isLeaf) {
            //清除选中  
            $('#Employee').combotree('clear');
            return;
        }

        //员工基本信息赋值
        var att = eval("({" + node.attributes + "})");
        $("#spanDeptName").html(att.DeptName);
        $("#spanJobName").html(att.JobName);
        $("#spanEmpCode").html(att.EmpCode);
        $("#spanEntryTime").html(att.EntryTime);
    }
});

方法

扩大的主意继承于 combo,下边是拉长和覆盖措施combotree.

名称 参数 说明
options none 返回选择对象。
tree none 返回对象的树。下面的例子显示了如何获得选中的树节点。

var t = $('#cc').combotree('tree');    // 获得树对象
var n = t.tree('getSelected');      // 获得选中节点显示(文本);
loadData data 加载本地组合树数据。代码示例:

$('#cc').combotree('loadData', [{id: 1,text: 'Languages',children: [{id: 11,text:'Java'},{id: 12,text: 'C++'}]}]);
reload url 再次请求远程树数据。通过“url”参数覆盖原始url值。
clear none 清除的组件值。
setValues values 设置组件值数组。代码示例:

$('#cc').combotree('setValues', [1,3,21]);
setValue value

设置组件的值。代码示例:

$('#cc').combotree('setValue', 6);
