下面我将为您详细介绍如何实现 "dtree 网页树状菜单及传递对象集合到js内,动态生成节点" 的攻略。
准备工作
为了实现这个功能,我们需要准备以下工作:
- 安装 dtree 插件
- 准备要展示的数据(例如:从后端获取到的树状结构数据)
使用 dtree 插件实现树状菜单
- 在 HTML 页面中引入 dtree 文件
<script src="./lib/js/jquery-1.11.1.min.js"></script>
<link rel='stylesheet' href='./lib/css/dtree.css' />
<script src='./lib/js/dtree.js'></script>
- 准备数据,将数据处理成 dtree 能够识别的 json 格式的数据
var menuData = [
{ "title" : "父节点1", "id" : "1", "spread" : true, "children" : [
{"title" : "子节点1-1", "id" : "11", "spread" : false},
{"title" : "子节点1-2", "id" : "12", "spread" : false}
]},
{ "title" : "父节点2", "id" : "2", "spread" : true, "children" : [
{"title" : "子节点2-1", "id" : "21", "spread" : false},
{"title" : "子节点2-2", "id" : "22", "spread" : false}
]},
{ "title" : "父节点3", "id" : "3", "spread" : true, "children" : [
{"title" : "子节点3-1", "id" : "31", "spread" : false},
{"title" : "子节点3-2", "id" : "32","spread" : false}
]}
];
- 初始化 dtree 插件
var node = document.getElementById("tree"); // 获取要显示树状结构的节点
var dTree = new dTree({
target: node, // 树状结构要显示的节点
extra: data // 自定义数据
});
dTree.init(menuData); // 初始化树状结构
- 渲染树状结构到页面上
dTree.show();
传递对象集合到js内,动态生成节点
- 在 HTML 页面中添加一个节点(例如 div)作为容器,用于显示动态生成的节点
<div id="dynamicTree"></div>
- 创建一个空的 dtree 对象
var dynamicDtree = new dTree();
- 动态添加节点
var nodeOne = dynamicDtree.add('0', '-1', '节点1', '', '', '', '', '', true);
var nodeTwo = dynamicDtree.add('1', '0', '节点2', '', '', '', '', '', true);
var nodeThree = dynamicDtree.add('2', '1', '节点3', '', '', '', '', '', true);
- 将动态生成的节点渲染到页面上
$("#dynamicTree").html(dynamicDtree.toString());

以下是一个使用 dtree 插件实现树状菜单的示例实现:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>示例1:dtree 网页树状菜单</title>
<script src="./lib/js/jquery-1.11.1.min.js"></script>
<link rel='stylesheet' href='./lib/css/dtree.css' />
<script src='./lib/js/dtree.js'></script>
</head>
<body>
<div id="tree"></div>
<script>
var node = document.getElementById("tree");
var menuData = [
{ "title" : "父节点1", "id" : "1", "spread" : true, "children" : [
{"title" : "子节点1-1", "id" : "11", "spread" : false},
{"title" : "子节点1-2", "id" : "12", "spread" : false}
]},
{ "title" : "父节点2", "id" : "2", "spread" : true, "children" : [
{"title" : "子节点2-1", "id" : "21", "spread" : false},
{"title" : "子节点2-2", "id" : "22", "spread" : false}
]},
{ "title" : "父节点3", "id" : "3", "spread" : true, "children" : [
{"title" : "子节点3-1", "id" : "31", "spread" : false},
{"title" : "子节点3-2", "id" : "32","spread" : false}
]}
];
var tree = new dTree({
target: node,
extra: menuData
});
tree.init(menuData);
tree.show();
</script>
</body>
</html>

以下是一个使用 dtree 插件动态生成节点的示例实现:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>示例2:dtree 动态生成节点</title>
<script src="./lib/js/jquery-1.11.1.min.js"></script>

<script src='./lib/js/dtree.js'></script>
</head>
<body>
<div id="dynamicTree"></div>
<script>
var dynamicDtree = new dTree();
var nodeOne = dynamicDtree.add('0', '-1', '节点1', '', '', '', '', '', true);
var nodeTwo = dynamicDtree.add('1', '0', '节点2', '', '', '', '', '', true);
var nodeThree = dynamicDtree.add('2', '1', '节点3', '', '', '', '', '', true);
var nodeFour = dynamicDtree.add('3', '2', '节点4', '', '', '', '', '', true);
var nodeFive = dynamicDtree.add('4', '3', '节点5', '', '', '', '', '', true);
$("#dynamicTree").html(dynamicDtree.toString());
</script>
</body>
</html>
