ZTree 设置默认选中节点

设置node节点checked选中,有两种方法实现:

（1）、zTree.checkNode(node, true, true);

（2）、node.checked = true;
  zTree.updateNode(node);  设置checked属性之后，一定要更新该节点。

function initZTree() {
	$.ajax({
		url: "/gcsoft/menu/getMenuTreeById.action?id=0",
		type: "post",
		dataType: "json",
		async: false,
		success: function(data) {
			var setting = {
				async: {
					enable: true,
					url: "/gcsoft/menu/getMenuTreeById.action",
					autoParam: ["id", "pid", "name"],
					dataFilter: filter
				},
				data: {
					simpleData: {
						enable: true,
						idKey: 'id',
						pIdKey: 'pid',
						rootPId: 0
					}
				},
				callback: {
					onAsyncSuccess: function zTreeOnAsyncSuccess(event, treeId, treeNode, msg) {
						var menuIds = '${menuIdArr}'.split(',');

						for(var i = 0; i < treeNode.children.length; i++) {
							for(var j = 0; j < menuIds.length; j++) {

                                       //第二种方法node.checked = true; 
                                      //再更新节点zTree.updateNode(node); 

								if(treeNode.children[i].id == menuIds[j])
									treeNode.children[i].checked = true
								    zTree.updateNode(treeNode.children[i]);
							}
						}
					},
					onCheck: click
				},
				check: {
					enable: true
				},
				view: {
					showIcon: false
				}
			};
			var zTree = $.fn.zTree.init($("#zTree"), setting, data);
			var menuIds = '${menuIdArr}'.split(',');
			for(var i = 0; i < menuIds.length; i++) {

                       //zTree.checkNode(node, true, true);

				var node = zTree.getNodeByParam("id", menuIds[i]);
				if(node != null) {
					zTree.checkNode(node, true)
				}
			}
		}
	});
}
