【zTree】zTree的3.5.26静态树与动态树(实用)

1.静态树:

目录结构:(css与js为下载的原文件夹)

代码

<!DOCTYPE html>

        var setting = {
            //多选框显示
            check: {
                enable: true
            },
            data: {
                simpleData: {
                    enable: true,
                    idKey: "id",
                    pIdKey: "pId",
                    rootPId: 0
                }
            },
            callback: {
                onClick: zTreeOnClick,
                onCheck: zTreeOnCheck
            }
        };
        var treeNodes = [{
                "id": 1,
                "pId": 0,
                "name": "test1"
            },
            {
                "id": 11,
                "pId": 1,
                "name": "test11"
            },
            {
                "id": 12,
                "pId": 1,
                "name": "test12"
            },
            {
                "id": 111,
                "pId": 11,
                "name": "test111"
            }
        ];

        //鼠标点击树事件
        function zTreeOnClick(event, treeId, treeNode) {
            alert(treeNode.id + ", " + treeNode.name);
        };
        //鼠标点击前面d复选框事件
        function zTreeOnCheck(event, treeId, treeNode) {
            //    treeNode.checked表示节点d选中状态(true|false)
            alert(treeNode.id + ", " + treeNode.name + treeNode.checked);
        };

        $(document).ready(function() {
            $.fn.zTree.init($("#treeDemo"), setting, treeNodes);

        });
    </script>

    <body>
        <div class="content_wrap">
            <div class="zTreeDemoBackground left">
                <ul id="treeDemo" class="ztree"></ul>
            </div>

        </div>
    </body>

</html>

测试:

点击树:

点击复选框:

2.动态生成带点击事件的树

页面中准备树位置

                            <div class="user_left_tree_info">
                                <div class="user_left_tree_info_title">部门</div>
                                <div class="hr"></div>
                                <div class="ztree" id="treeDemo"></div>
                            </div>

Js请求树数据与生成树结构:

$(function() {
    alert(contextPath)
    var zNodes10;
    $.ajax({
        url : contextPath + '/exam_getDepartmentTree.action',
        async : true,
        dataType : 'json',
        success : function(response) {
            zNodes10 = response.departmentTrees;
            // 生成树结构
            geneDepartmentTree(zNodes10);

        },
        error : function() {
            alert("查询内部部门树失败！！！")
        }
    });
    }
//生成树函数
function geneDepartmentTree(departmentTrees) {
    var setting = {
        view : {
            selectedMulti : false
        },
        check : {
            enable : true
        },
        data : {
            simpleData : {
                enable : true,
                enable : true,
                idKey : "departmentId",
                pIdKey : "upDepartmentId",
                rootPId : null
            },
            key : {
                name : "departmentName",
            }
        },
        callback : {
            onClick : zTreeOnClick
        }
    };
    var treeNodes = departmentTrees;
    $.fn.zTree.init($("#treeDemo"), setting, treeNodes);
}
// 鼠标点击树事件(打印点击的id与名字)
function zTreeOnClick(event, treeId, treeNode) {
    alert(treeNode.departmentId + ", " + treeNode.departmentName);
}

后台返回的JSON数据格式:(主要返回部门ID，上级ID，部门姓名即可构成一颗树)

{"departmentTrees":[{"departmentId":"10","departmentName":"厂级-1"},{"departmentId":"10001","departmentName"
:"部门1_10","upDepartmentId":"10"},{"departmentId":"10001001","departmentName":"班组1_10001","upDepartmentId"
:"10001"},{"departmentId":"10002","departmentName":"部门2_10","upDepartmentId":"10"},{"departmentId":"10002001"
,"departmentName":"班组2_10002","upDepartmentId":"10002"},{"departmentId":"10003","departmentName":"部门3_10"
,"upDepartmentId":"10"},{"departmentId":"11","departmentName":"厂级-2"},{"departmentId":"11001","departmentName"
:"部门1_11","upDepartmentId":"11"},{"departmentId":"12","departmentName":"厂级-3"}]}

结果:

点击树:

3.更复杂的关于树的点击事件参考:

另一个例子:(带有单选按钮的树)

    });
}

/************S   点击事件*********/
function clickNode(e, treeId,treeNode) {
    $("#trainContentTypeId").val(treeNode.typeId);//向隐藏的类别编号赋值
    $("[name='typeId']").val(treeNode.typeId);//向隐藏的类别编号赋值
    $("#yeHao").val("1");
    btnFindFy();
}
/************E   点击事件*********/


function openModal(){
    $("#el_empTrainDoc").modal("show");
}
