ztree代码，带有检索功能

以下是一个简单的带有检索功能的ztree代码示例：

HTML代码：

<div>
  <input type="text" id="search-input" placeholder="输入关键字进行搜索">
  <button id="search-btn">搜索</button>
</div>
<div id="tree"></div>

JavaScript代码：

// 初始化ztree
var setting = {
  data: {
    simpleData: {
      enable: true
    }
  }
};
var zNodes = [
  { id:1, pId:0, name:"父节点1 - 展开", open:true},
  { id:11, pId:1, name:"父节点11 - 折叠"},
  { id:111, pId:11, name:"叶子节点111"},
  { id:112, pId:11, name:"叶子节点112"},
  { id:113, pId:11, name:"叶子节点113"},
  { id:114, pId:11, name:"叶子节点114"},
  { id:12, pId:1, name:"父节点12 - 折叠"},
  { id:121, pId:12, name:"叶子节点121"},
  { id:122, pId:12, name:"叶子节点122"},
  { id:123, pId:12, name:"叶子节点123"},
  { id:124, pId:12, name:"叶子节点124"},
  { id:13, pId:1, name:"父节点13 - 没有子节点", isParent:true},
  { id:2, pId:0, name:"父节点2 - 折叠"},
  { id:21, pId:2, name:"父节点21 - 展开", open:true},
  { id:211, pId:21, name:"叶子节点211"},
  { id:212, pId:21, name:"叶子节点212"},
  { id:213, pId:21, name:"叶子节点213"},
  { id:214, pId:21, name:"叶子节点214"},
  { id:22, pId:2, name:"父节点22 - 折叠"},
  { id:221, pId:22, name:"叶子节点221"},
  { id:222, pId:22, name:"叶子节点222"},
  { id:223, pId:22, name:"叶子节点223"},
  { id:224, pId:22, name:"叶子节点224"},
  { id:23, pId:2, name:"父节点23 - 折叠"},
  { id:231, pId:23, name:"叶子节点231"},
  { id:232, pId:23, name:"叶子节点232"},
  { id:233, pId:23, name:"叶子节点233"},
  { id:234, pId:23, name:"叶子节点234"}
];
$.fn.zTree.init($("#tree"), setting, zNodes);

// 搜索功能
$("#search-btn").click(function() {
  var keyword = $.trim($("#search-input").val());
  if (keyword === "") {
    alert("请输入关键字");
    return;
  }
  var zTreeObj = $.fn.zTree.getZTreeObj("tree");
  var nodes = zTreeObj.getNodesByParamFuzzy("name", keyword, null);
  if (nodes.length === 0) {
    alert("没有找到匹配的节点");
  } else {
    zTreeObj.selectNode(nodes[0]);
    zTreeObj.expandAll(true);
  }
});

当用户输入关键字并点击“搜索”按钮时，代码将使用`getNodesByParamFuzzy()`方法查找所有匹配的节点，并将第一个匹配的节点选中并展开其所有父节点。如果没有找到匹配的节点，则显示一个提示框。
