JQuery 目录树jsTree插件用法

PHP循环构造目录树结构

 <ul>

  <php>

       function digui($fid,$level){

         $class=M("wangpan_class")->where('fid='.$fid)->select();

        foreach($class as $v){

              		$child=M("wangpan_class")->where('fid='.$v['id'])->select();//如果不为空，表示有子类

			if(!empty($child)){

			echo "<li>".str_repeat("  ",$level)."┗".$v['name']."<ul>";

			}else{

				echo "<li>".str_repeat("  ",$level)."┗".$v['name']."</li>";

				}

             digui($v['id'],$level+1);

			if(!empty($child)){

			echo "</ul></li>";//如果有子类才输出ul / li

			}

            }

        }

		 digui(0,0);

 </php>

</ul>

jsTree DEMO

实现点击获取节点ID，实现配置复选框

/*jsTree代码begin  */

 $('#jstree').jstree();

 $("#jstree").jstree({

    "types" : {

      "default" : {

        "icon" : "glyphicon glyphicon-flash"

      },

      "demo" : {

        "icon" : "glyphicon glyphicon-ok"

      }

    },

    "plugins" : [ "types" ]

  });   // 7 bind to events triggered on the tree

 /* 开启checkbox

 $("#jstree").jstree({

    "checkbox" : {

      "keep_selected_style" : false

    },

    "plugins" : [ "checkbox" ]

  });*/

   $("#plugins")

    .on("changed.jstree", function (e, data) {

      console.log(data.changed.selected); // newly selected

      console.log(data.changed.deselected); // newly deselected

    })

    .jstree({

      "plugins" : [ "changed" ]

    });

  $('#jstree').on("changed.jstree", function (e, data) {

      console.log(data.selected);

       var id = $(e.target).html();

     // alert(id);

    });

  $('#jstree').bind("activate_node.jstree", function (obj, e) {

    // 获取当前节点

    alert(e.node.id);//得到被点击节点的id

});      

 /*end  jsTree*/

jstree官网：https://www.jstree.com/

1.需要导入的文件

<link rel="stylesheet" href="dist/themes/default/style.min.css" />

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.1/jquery.min.js"></script>

<script src="dist/jstree.min.js"></script>

2.在页面上创建一个jstree容器（div）

<div id="jstree_demo_div"></div>

3.创建一个jstree实例

<script type="text/javascript">

	$('#jstree_demo_div1').jstree({'plugins':["wholerow","checkbox"], 'core' : {

		'data' : [

			{

				"text" : "Same but with checkboxes",

				"children" : [

					{ "text" : "initially selected", "state" : { "selected" : true } },

					{ "text" : "custom icon URL"},

					{ "text" : "initially open", "state" : { "opened" : true }, "children" : [ "Another node" ] },

					{ "text" : "custom icon class"}

				]

			},

			"And wholerow selection"

		]

	}});

</script>

效果：

4.ajax动态加载jstree

$.getJSON("/FIMS/api/rest/RolePermission/loadPermissionTreeData",{ts_role_id:ts_role_id}, function(json){

		$('#rolePermissionTree').jstree({'plugins':['checkbox'], 'core' : {

				'data' : json.datalist

		}});

	}

);

5.清空树（数据库的信息更新后想要刷新树，先要清空树）

$('#perjstree').data('jstree', false).empty();

6.绑定节点点击事件

$('#orgjstree').bind("activate_node.jstree", function (obj, e) {

	// 获取当前节点

	alert(e.node.id);//得到被点击节点的id

});

7.得到所有被选中的节点的id（先加上'plugins':["checkbox"]，使所有的节点前面加上checkbox）

var ids = $('#rolePermissionTree').jstree().get_checked();
