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); 
});
