前言
zTree 是一個依靠 jQuery 實現的多功能 “樹插件”。優異的性能、靈活的配置、多種功能的組合是 zTree 最大優點。
支持靜態 和 Ajax 異步加載節點數據.
在開發中我們常需要用到樹狀的展示.

JS方式一-簡單json數據格式

<SCRIPT type="text/javascript"> <!-- var setting = { }; var zNodes =[ { name:"父節點1 - 展開", open:true, children: [ { name:"父節點11 - 折疊", children: [ { name:"葉子節點111"}, { name:"葉子節點112"}, { name:"葉子節點113"}, { name:"葉子節點114"} ]}, { name:"父節點12 - 折疊", children: [ { name:"葉子節點121"}, { name:"葉子節點122"}, { name:"葉子節點123"}, { name:"葉子節點124"} ]}, { name:"父節點13 - 沒有子節點", isParent:true} ]}, { name:"父節點2 - 折疊", children: [ { name:"父節點21 - 展開", open:true, children: [ { name:"葉子節點211"}, { name:"葉子節點212"}, { name:"葉子節點213"}, { name:"葉子節點214"} ]}, { name:"父節點22 - 折疊", children: [ { name:"葉子節點221"}, { name:"葉子節點222"}, { name:"葉子節點223"}, { name:"葉子節點224"} ]}, { name:"父節點23 - 折疊", children: [ { name:"葉子節點231"}, { name:"葉子節點232"}, { name:"葉子節點233"}, { name:"葉子節點234"} ]} ]}, { name:"父節點3 - 沒有子節點", isParent:true} ]; $(document).ready(function(){ $.fn.zTree.init($("#treeDemo"), setting, zNodes); }); //--> </SCRIPT>異步zTree加載
前面的配置相同,在此不再闡述.主要是js不同.
異步JS
var setting = { //可勾選 check: { enable: true }, data : { simpleData : { enable : true } }}; function initTree(){ var payFreq = $("#payFreq").val(); var fyType = $('#fyType').val(); var setHzType = $('#setHzType').val(); $.ajax({ url : "/demo/initTree", data : {payFreq:payFreq, fyType:fyType, setHzType:setHzType }, success: function(object){ var nodes = ""; //拼接simple格式的json字符串 $.each(object.data, function(i,item) { nodes+="{id:'"+item.id+"', pId:'"+item.pid+"', name:'"+item.name+"', isParent:'"+item.isParent+"'},"; }); var zNodes = "["+nodes+"]"; var json = eval('(' + zNodes + ')'); //console.log(json); zTreeInit(json); } }); } /* 初始化樹 */ function zTreeInit(json) { $.fn.zTree.init($("#treeDemo"), setting, json); var zTree = $.fn.zTree.getZTreeObj("treeDemo"); //全部展開 zTree.expandAll(true); //Y代表勾選時,N代表取消勾選 p代表父節點,s代表字節點 setting.check.chkboxType = { "Y" : "ps", "N" : "ps" }; }java代碼
Controller層
@RequestMapping("initTree") @ResponseBody public DataMessage initTree(String setHzType,String payFreq,String fyType){ params.put("setHzType", setHzType); params.put("fyType", fyType); params.put("fkmattr_xt", fkmattr_xt); //獲取treeinfo列表 List<TreeInfo> treeInfos = feeTransferService.initTree(params); return DataMessage.successData(treeInfos); }tree實體類
public class TreeInfo { private String id; private String pid; private String name; private String isParent; }說明

或參見zTree GitHub 里面更多的示例和說明。
