zTree2.6 动态Check赋值
在前台这么写，后台直接SQL查询就能赋值了 <script type="text/javascript"> var setting = { async: { enable: true, url: '/YY_BD_FaultType/JsonCYTimeApp', autoParam: ["id","pId", "name=n"], otherParam: { "otherParam": "zTreeAsyncTest" }, dataFilter: filter }, data: { simpleData: { enable: true } }, check: { enable: true}, callback: { beforeCheck: beforeCheck, onCheck: onCheck } }; function filter(treeId, parentNode, childNodes) { if (!childNodes) return null; for (var i = 0, l = childNodes.length; i < l; i++) { childNodes.name = childNodes.name.replace(/\.n/g, '.'); } return childNodes; } var code, log, className = "dark"; function beforeCheck(treeId, treeNode) { className = (className === "dark" ? "" : "dark"); // showLog(treeNode.name); return (treeNode.doCheck !== false); } function onCheck(e, treeId, treeNode) { if (treeNode.checked == true) { showLog(treeNode.id); } } function showLog(str) { if (!log) log = $("#log"); log.append(str); zhi(str) if (log.children("li").length > 6) { log.get(0).removeChild(log.children("li")) } } function zhi(str) { document.getElementById("ID").value = str; } function checkNode(e) { var zTree = $.fn.zTree.getZTreeObj("treeDemo"), type = e.data.type, nodes = zTree.getSelectedNodes(); if (type.indexOf("All") < 0 && nodes.length == 0) { alert("请先选择一个节点"); } if (type == "checkAllTrue") { zTree.checkAllNodes(true); } else if (type == "checkAllFalse") { zTree.checkAllNodes(false); } else { for (var i = 0, l = nodes.length; i < l; i++) { if (type == "checkTrue") { zTree.checkNode(nodes, true); } else if (type == "checkFalse") { zTree.checkNode(nodes, false); } else if (type == "checkTruePS") { zTree.checkNode(nodes, true, true); } else if (type == "checkFalsePS") { zTree.checkNode(nodes, false, true); } } } } $(document).ready(function () { $.fn.zTree.init($("#treeDemo"), setting); $("#checkTrue").bind("click", { type: "checkTrue" }, checkNode); $("#checkFalse").bind("click", { type: "checkFalse" }, checkNode); $("#checkTruePS").bind("click", { type: "checkTruePS" }, checkNode); $("#checkFalsePS").bind("click", { type: "checkFalsePS" }, checkNode); $("#checkAllTrue").bind("click", { type: "checkAllTrue" }, checkNode); $("#checkAllFalse").bind("click", { type: "checkAllFalse" }, checkNode); }); </script>2.
设置勾选状态，请修改node数据的 checked属性，然后利用updateNode方法更新即可，请注意 checkTypeFlag参数，按照你需要的情况设定。 在v3.0中，将会提供checkNode方法，可以专门用于设置勾选状态，当然updateNode也还保有目前的功能。
3.终
setTimeout(function() { zTree.checkAllNodes(true); },3000);
