jQuery中ztree 点击文本框弹出下拉框的实例代码

废话不多说了，具体代码如下所示：

<link rel="stylesheet" href="${ctx}/res/js/ztree/css/demo.css" type="text/css"/>
<link rel="stylesheet" href="${ctx}/res/js/ztree/css/zTreeStyle/zTreeStyle.css" type="text/css"/>
<script type="text/javascript" src="${ctx}/res/js/ztree/js/jquery.ztree.core-3.5.js"></script> 

<input onclick="showMenu();return false;"/> 

var setting = {
  view: {
    dblClickExpand: false
  },
  data: {
    simpleData: {
      enable: true
    }
  },
  callback: {
    onClick: onClick
  }
};
function onClick(e, treeId, treeNode) {
  var zTree = $.fn.zTree.getZTreeObj("treeDemo"),
  nodes = zTree.getSelectedNodes();
  menuName = "";
  menuId = "";
  nodes.sort(function compare(a,b){return a.id-b.id;});
  var isParent = nodes[0].getParentNode();
  var isChildren = nodes[0].children;
  if((!isParent && !isChildren) || (isParent)){
    for (var i=0, l=nodes.length; i<l; i++) {
      menuName += nodes[i].name + ",";
      menuId += nodes[i].id + ",";
    }
    if (menuName.length > 0 ) menuName = menuName.substring(0, menuName.length-1);
    if (menuId.length > 0 ) menuId = menuId.substring(0, menuId.length-1);
   $("#menuName").val(menuName);
    $("#menuId").val(menuId);
  }
}
function showMenu() {
  var cityObj = $("#menuName");
  var cityOffset = $("#menuName").offset();
  $("#menuContent").css({left:cityOffset.left + "px", top:cityOffset.top + cityObj.outerHeight() + "px"}).slideDown("fast")
 $("body").bind("mousedown", onBodyDown);
  var width = cityObj.css("width");
  $("#treeDemo").css("width",parseInt(width)-5);
}
function hideMenu() {
  $("#menuContent").fadeOut("fast");
  $("body").unbind("mousedown", onBodyDown);
}
function onBodyDown(event) {
 if (!(event.target.id == "menuContent" || $(event.target).parents("#menuContent").length>0)) {
    hideMenu();
  }
  }
$(document).ready(function(){
  $.fn.zTree.init($("#treeDemo"), setting, zNodes);
});
