本文介绍了在Ztree中进行多选和单选操作的方法，包括选择值的获取与设置、初始化选择状态、点击发送请求、获取所有子节点及清空选中值的实现。通过设置checked参数，可以实现节点的全选和全取消选中。提供了代码示例以供参考。

  • ztree获取所有的子节点

 

 var ChildId = '';
 ChildId = getAllChildrenNodes(treeNode, ChildId);
function getAllChildrenNodes(treeNode, result) {
        if (treeNode.isParent) {
            var childrenNodes = treeNode.children;

ztree清空所有选中值

参数说明： 
checked = true 表示勾选全部节点 
checked = false 表示全部节点取消勾选 
代码示例如下：

var treeObj = $.fn.zTree.getZTreeObj("treeDemo");
treeObj.checkAllNodes(false);

多选树

//部门多选树
    var settingCheckAll = {
        check: {
            enable: true
        },
        view: {
            showIcon: false,
            showLine: true,
            dblClickExpand: true,
            selectedMulti: false
        },
        data: {
            simpleData: {
                enable: true,
                idKey: "id",
                pIdKey: "pId",
                rootPId: 0
            }
        }

    };

动态渲染ztree

    var tUser = $("#userTree");
    var tDept = $("#deptTree");
    var pDept = $("#pDeptTree");


  $.ajax({
        type: "GET",
        url: '/xxx/',
        data: {},
        dataType: 'json',
        cache: false,
        success: function (result) {
            console.log(result)
            var deptList=result.dept_list
            deptList.forEach(function(v,i,a){ 
                zNodesDept.push({
                    "id":a[i].id,
                    "pId":a[i].PDept,
                    "name":a[i].DeptName,
                    "open":0
                })
      
            })
            tUser = $.fn.zTree.init(tUser, settingUser, zNodesDept);
            tDept = $.fn.zTree.init(tDept, settingCheckAll, zNodesDept);
          

        }
