一、说明
(1)通过后台查询数据库,生成树形数组结构,返回到前台。
(2)需要引入的js插件和css文件:
①jquery.jOrgChart.css
②jquery.min.js
③jquery.jOrgChart.js
(3)使用jOrgChart插件,根据返回的数据将其子节点加入到相应的<li></li>中。
首先,我们的数据表应该要有 id(节点),pid(父节点的id),name的字段,
那么我们要把这个数组转为树形数组结构,即将各个元素放在 pid 父类元素的 childrens字段中,下面就是简单生成树形数组的代码。至于展示出来的样式,可以在html页面中添加自定义样式覆盖它之前的样式。
注意:
后台返回的数据格式必须如下,其中id,pid字段为必须要有。childrens字段也为必须的,不过字段名可以自己定义,name字段是根据自己业务需求的字段,在这里以name字段作为要显示的文本内容:
{ "data": [{ "id": 1, "name": "企业主体信用得分", "pid": null, "childrens": [ { "id": 2, "name": "企业素质", "pid": 1, "childrens": [ { "id": 5, "name": "基本信息", "pid": 2, "childrens": [ { "id": 10, "name": "企业主体信息识别", "pid": 5, "childrens": [ ] }, { "id": 11, "name": "企业持续注册时间", "pid": 5, "childrens": [ ] }, { "id": 12, "name": "注册资本", "pid": 5, "childrens": [ ] } ] }, { "id": 6, "name": "管理认证", "pid": 2, "childrens": [ { "id": 13, "name": "国际性管理认证", "pid": 6, "childrens": [ ] } ] } ] }, { "id": 3, "name": "履约记录", "pid": 1, "childrens": [ { "id": 7, "name": "税务执行情况", "pid": 3, "childrens": [ { "id": 14, "name": "是否按时缴纳税款", "pid": 7, "childrens": [ ] } ] }, { "id": 8, "name": "网贷情况", "pid": 3, "childrens": [ { "id": 15, "name": "网贷逾期", "pid": 8, "childrens": [ ] } ] } ] }, { "id": 4, "name": "公共监督", "pid": 1, "childrens": [ { "id": 9, "name": "行政处罚", "pid": 4, "childrens": [ { "id": 16, "name": "处罚信息", "pid": 9, "childrens": [ ] } ] } ] } ] } ] }
二、实例:
1、json文件(test.json)(即后台接口返回的json格式的数据)
{ "data": [{ "id": 1, "name": "企业主体信用得分", "pid": null, "childrens": [ { "id": 2, "name": "企业素质", "pid": 1, "childrens": [ { "id": 5, "name": "基本信息", "pid": 2, "childrens": [ { "id": 10, "name": "企业主体信息识别", "pid": 5, "childrens": [ ] }, { "id": 11, "name": "企业持续注册时间", "pid": 5, "childrens": [ ] }, { "id": 12, "name": "注册资本", "pid": 5, "childrens": [ ] } ] }, { "id": 6, "name": "管理认证", "pid": 2, "childrens": [ { "id": 13, "name": "国际性管理认证", "pid": 6, "childrens": [ ] } ] } ] }, { "id": 3, "name": "履约记录", "pid": 1, "childrens": [ { "id": 7, "name": "税务执行情况", "pid": 3, "childrens": [ { "id": 14, "name": "是否按时缴纳税款", "pid": 7, "childrens": [ ] } ] }, { "id": 8, "name": "网贷情况", "pid": 3, "childrens": [ { "id": 15, "name": "网贷逾期", "pid": 8, "childrens": [ ] } ] } ] }, { "id": 4, "name": "公共监督", "pid": 1, "childrens": [ { "id": 9, "name": "行政处罚", "pid": 4, "childrens": [ { "id": 16, "name": "处罚信息", "pid": 9, "childrens": [ ] } ] } ] } ] } ] }
2、html页面(test.html)
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>jOrgChart异步加载</title> <link rel="stylesheet" href='jquery.jOrgChart.css'/> <script type='text/javascript' src='jquery.min.js'></script> <script type='text/javascript' src='jquery.jOrgChart.js'></script> <style> a { text-decoration: none; color: #fff; font-size: 12px; } .jOrgChart .node { width: 120px; height: 50px; line-height: 50px; border-radius: 4px; margin: 0 8px; } </style> </head> <body> <!--显示组织架构图--> <div id='jOrgChart'></div> <script type='text/javascript'> $(function(){ //数据返回 $.ajax({ url: "test.json", type: 'GET', dataType: 'JSON', data: {action: 'org_select'}, success: function(result){ var showlist = $("<ul id='org' style='display:none'></ul>"); showall(result.data, showlist); $("#jOrgChart").append(showlist); $("#org").jOrgChart( { chartElement : '#jOrgChart',//指定在某个dom生成jorgchart dragAndDrop : false //设置是否可拖动 }); } }); }); function showall(menu_list, parent) { $.each(menu_list, function(index, val) { if(val.childrens.length > 0){ var li = $("<li></li>"); li.append("<a href='javascript:void(0)' onclick=getOrgId("+val.id+");>"+val.name+"</a>").append("<ul></ul>").appendTo(parent); //递归显示 showall(val.childrens, $(li).children().eq(1)); }else{ $("<li></li>").append("<a href='javascript:void(0)' onclick=getOrgId("+val.id+");>"+val.name+"</a>").appendTo(parent); } }); } </script> </body> </html>
3、效果图(打开test.html页面后即可看到如下效果)
注意:由于数据是由ajax异步请求获取到的,所以直接双击html文件打开是不行的,需要在服务器环境下运行。
