hortree是一个小而简单的jQuery插件,它有助于从JSON文件中指定的层次数据中呈现类似水平树视图的图表。
1.创建一个容器元素来放置水平层次树。
- <div id="my-container"></div>
2.包含jQuery库和JavaScript文件jquery.hortree.min.js查询
在网页底部。
- <script src="//code.jquery.com/jquery.min.js"></script>
- <script src="jquery.hortree.min.js"></script>
3.如果您想在父节点和子节点之间画一条线,请包含jQuery Line插件。
- <script src="jquery.line.js"></script>
4.在JSON文件中定义分层数据。
- [
- {
- "description": "Element ROOT",
- "children": [
- {
- "description": "Element 1",
- "children": [
- {
- "description": "Element 1.1",
- "children": []
- },
- {
- "description": "Element 1.2",
- "children": [
- {
- "description": "Element 1.2.1",
- "children": []
- }
- ]
- }
- ]
- },
- {
- "description": "Element 2",
- "children": [
- {
- "description": "Element 2.1",
- "children": []
- },
- {
- "description": "Element 2.2",
- "children": []
- }
- ]
- },
- {
- "description": "Element 3",
- "children": [
- {
- "description": "Element 3.1",
- "children": []
- },
- {
- "description": "Element 3.2",
- "children": []
- },
- {
- "description": "Element 3.3",
- "children": [
- {
- "description": "Element 3.3.1",
- "children": []
- },
- {
- "description": "Element 3.3.2",
- "children": []
- }
- ]
- }
- ]
- }
- ]
- }
- ]
5.在您刚刚创建的容器中渲染默认层次结构树的JavaScript。
- $.getJSON('data.json', function (jsonData) {
- $('#my-container').hortree({
- data: jsonData
- });
- });
6.将您自己的CSS样式应用于层次结构树。
- .hortree-wrapper *, .hortree-wrapper *:before, .hortree-wrapper *:after {
- -webkit-box-sizing: border-box;
- -moz-box-sizing: border-box;
- box-sizing: border-box;
- }
- .hortree-wrapper {
- position: relative;
- font-family: sans-serif, Verdana, Arial;
- font-size: 0.9em;
- }
- .hortree-branch {
- position: relative;
- margin-left: 180px;
- }
- .hortree-branch:first-child { margin-left: 0; }
- .hortree-entry {
- position: relative;
- margin-bottom: 50px;
- }
- .hortree-label {
- display: block;
- width: 150px;
- padding: 2px 5px;
- line-height: 30px;
- text-align: center;
- border: 2px solid #4b86b7;
- border-radius: 3px;
- position: absolute;
- left: 0;
- z-index: 10;
- background: #fff;
- }
7.或直接包括jquery.hortree.css查询
在头部
部分。
- <link rel="stylesheet" href="jquery.hortree.css">
8.默认插件选项。
- $('#my-container').hortree({
- lineStrokeWidth: 2,
- lineZindex: 8,
- lineColor: '#4b86b7',
- data: [],
- onComplete: function () {
- // onComplete callback
- }
- });
