Ztree使用总结（一次性加载与异步加载）

  • ztree树形显示，结构清晰
    • 一次性加载数据：
    • 异步加载:
    • 异步加载，带上搜索功能
    • 拼音搜索--亲测可行

ztree树形显示，结构清晰

示例如下：

一次性加载数据：

var setting = {async:{autoParam:[],//异步加载需要带的查询参数contentType:"application/x-www-form-urlencoded",//Ajax 提交参数的数据类型。[setting.async.enable = true 时生效]//默认值："application/x-www-form-urlencoded"dataType:"text",//ajax请求返回的数据类型enable:false,//是否是异步请求type:"post",//ajax请求类型url:""//ajax请求的地址},callback:{beforeAsync:null,//异步请求前的回调函数beforeClick:null,//点击前回调函数onAsyncSuccess:null,//异步请求成功回调函数onClick:null,//单击时回调函数},data:{keep:{leaf:false,parent:false},key:{name:"name",title:" ",url:"url"},simpleData:{enable:true,idKey:"id",pIdKey:"pId",rootPId:"0"}},view:{fontCss:{color:"white"}, //文字样式showIcon: true,showLine: true,ShowTitle: true,nameIsHTML: true,expandSpeed: "slow"}
};$(function() {var url = "/function/tree/testRequestData";$.ajax({type: "GET",url: url,data: {},success: function(data) {initThisZtree(data);},error:function(){}});
});/*** 初始化ztree* * @param {Object} data*/
function initThisZtree(data){//初始化ztree三个参数分别是(jQuery对象,ztree设置,树节点数据)var treeObj = $.fn.zTree.init($("#tree"), setting, data); //treeObj.expandAll(true);  //将所有节点展开
}function zOnClick(event, treeId, treeNode) {var treeId = treeNode.id;var treeName = treeNode.name;$("#treeId").val(treeId);$("#treeName").val(treeName);var url = $("#mainframe").attr("src");if(url.indexOf("?stId") > -1){url = url.split("?")[0];}url = url + "?stId=" +treeId;$("#mainframe").attr("src",url);
}
</script>
</body>	
</html>

后台：
后台就是正常controller，接收前端前后，获取节点数据。

	@GetMapping("/testRequestData")@ResponseBodypublic List<ZTreeNode> testTreeData() {HttpSession httpSession = ServletUtils.getSession();String userArea = (String)httpSession.getAttribute("userArea");if(userArea == null || userArea.equals("")) {userArea = "113715890591105063";//113715891161530369   113715890591105063}//List<ZTreeNode> list = treeNodeQuery.getTreeDatasById(userArea);List<ZTreeNode> list = treeNodeQuery.getExpandTreeDatasById(userArea);return list;}

具体的后台查库获取节点信息就不写了，暂无通用性

异步加载:

<script type="text/javascript">
var zNodes ;
//ztree配置
var setting = {async: {enable: true,type:"get",url:"/function/tree/asyncRequestData",autoParam:["id", "level"],dataFilter: filter},data:{simpleData:{enable: true,idKey:'id',pIdKey:'pid',rootPId: 0}},view:{fontCss:{color:"white"}, //文字样式showIcon: true,showLine: true,ShowTitle: true,nameIsHTML: true,expandSpeed: "slow"}

$(document).ready(function(){initZTree();
});function filter(treeId, parentNode, childNodes) {return childNodes;
}
//初始化树
function initZTree(){$.ajax({url:"/function/tree/testRequestData",type:"get",dataType: "json",success: function(data){console.log(data);var zTreeObj = $.fn.zTree.init($("#tree"),setting, data); //让第一个父节点展开//zTreeObj.expandAll(true);//展开一级节点var nodes0 = zTreeObj.getNodesByParam("level", "0");for(var i=0; i<nodes0.length; i++){zTreeObj.expandNode(nodes0[i], true);}//展开二级节点var nodes1 = zTreeObj.getNodesByParam("level", "1");for(var i=0; i<nodes1.length; i++){zTreeObj.expandNode(nodes1[i], true);}},error: function(){}});
}
</script></body>	
</html>

后台：
异步加载后台，分为两步：
1.初始ajax请求，获取根节点，或者自定义想一次性展开的节点数据
2.根据上面最底层以后的数据实现异步加载，通过传入节点的id及level
如下：
第一步如下：

	@GetMapping("/testRequestData")@ResponseBodypublic List<ZTreeNode> testTreeData() {HttpSession httpSession = ServletUtils.getSession();String userArea = (String)httpSession.getAttribute("userArea");if(userArea == null || userArea.equals("")) {userArea = "113715890591105063";//113715891161530369   113715890591105063}//List<ZTreeNode> list = treeNodeQuery.getTreeDatasById(userArea);List<ZTreeNode> list = treeNodeQuery.getExpandTreeDatasById(userArea);return list;}

第二步，异步加载：

	@GetMapping("/asyncRequestData")@ResponseBodypublic List<ZTreeNode> asyncRequestData() {String id = ServletUtils.getParameter("id");String level = ServletUtils.getParameter("level");List<ZTreeNode> list = treeNodeQuery.getAsyncTreeDatasById(id, level);return list;}

异步加载，带上搜索功能

$("#search_content").on('keypress', function (event) {if (event.keyCode == 13) {searchM();}
});function searchM() {var param = $.trim($("input[name='param']").val());var treeObj = $.fn.zTree.getZTreeObj("tree");var node = treeObj.getNodeByParam("name", param, null);if(param != ""){param = encodeURI(encodeURI(param));treeObj.setting.async.otherParam=["param", param];}else {//搜索参数为空时必须将参数数组设为空treeObj.setting.async.otherParam=[];}treeObj.selectNode(node); //让搜索节点在可视区域内treeObj.reAsyncChildNodes(node, "refresh");}function zTreeOnNodeCreated(event, treeId, treeNode) {var param = $.trim($("input[name='param']").val());var treeObj = $.fn.zTree.getZTreeObj("tree");//只有搜索参数不为空且该节点为父节点时才进行异步加载if(param != "" && treeNode.isParent){treeObj.reAsyncChildNodes(treeNode, "refresh");} 
};</script>
</body>	
</html>

后台和异步加载一样，搜索功能不涉及后台逻辑。

附录：
带上ztreeNode.java源码：

public class ZTreeNode implements Serializable{private static final long serialVersionUID = 5886322299632761687L;public String id;public String pId;public String name;	// 名称public boolean open=false;public String file;public Boolean isParent;public String getpId() {return pId;}public void setpId(String pId) {this.pId = pId;}public Boolean getIsParent() {return isParent;}public void setIsParent(Boolean isParent) {this.isParent = isParent;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getPId() {return pId;}public void setPId(String id) {pId = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public boolean getOpen() {return open;}public void setOpen(boolean open) {this.open = open;}public String getFile() {return file;}public void setFile(String file) {this.file = file;}public ZTreeNode(){}public ZTreeNode(String id,String pId,String name,String file){this.id=id;this.pId=pId;this.name=name;this.file=file;}
}

如果节点属性有拓展，可以通过，新建类来继承ztreeNode类。
