一、說明
(1)通過后台查詢數據庫,生成樹形數組結構,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,根據返回的數據將其子節點加入到相應的<li></li>中。
首先,我們的數據表應該要有 id(節點),pid(父節點的id),name的字段,
那么我們要把這個數組轉為樹形數組結構,即將各個元素放在 pid 父類元素的 childrens字段中,下面就是簡單生成樹形數組的代碼。至於展示出來的樣式,可以在html頁面中添加自定義樣式覆蓋它之前的樣式。
注意:
后台返回的數據格式必須如下,其中id,pid字段為必須要有。childrens字段也為必須的,不過字段名可以自己定義,name字段是根據自己業務需求的字段,在這里以name字段作為要顯示的文本內容:
{ "data": [{ "id": 1, "name": "企業主體信用得分", "pid": null, "childrens": [ { "id": 2, "name": "企業素質", "pid": 1, "childrens": [ { "id": 5, "name": "基本信息", "pid": 2, "childrens": [ { "id": 10, "name": "企業主體信息識別", "pid": 5, "childrens": [ ] }, { "id": 11, "name": "企業持續注冊時間", "pid": 5, "childrens": [ ] }, { "id": 12, "name": "注冊資本", "pid": 5, "childrens": [ ] } ] }, { "id": 6, "name": "管理認證", "pid": 2, "childrens": [ { "id": 13, "name": "國際性管理認證", "pid": 6, "childrens": [ ] } ] } ] }, { "id": 3, "name": "履約記錄", "pid": 1, "childrens": [ { "id": 7, "name": "稅務執行情況", "pid": 3, "childrens": [ { "id": 14, "name": "是否按時繳納稅款", "pid": 7, "childrens": [ ] } ] }, { "id": 8, "name": "網貸情況", "pid": 3, "childrens": [ { "id": 15, "name": "網貸逾期", "pid": 8, "childrens": [ ] } ] } ] }, { "id": 4, "name": "公共監督", "pid": 1, "childrens": [ { "id": 9, "name": "行政處罰", "pid": 4, "childrens": [ { "id": 16, "name": "處罰信息", "pid": 9, "childrens": [ ] } ] } ] } ] } ] }
二、實例:
1、json文件(test.json)(即后台接口返回的json格式的數據)
{ "data": [{ "id": 1, "name": "企業主體信用得分", "pid": null, "childrens": [ { "id": 2, "name": "企業素質", "pid": 1, "childrens": [ { "id": 5, "name": "基本信息", "pid": 2, "childrens": [ { "id": 10, "name": "企業主體信息識別", "pid": 5, "childrens": [ ] }, { "id": 11, "name": "企業持續注冊時間", "pid": 5, "childrens": [ ] }, { "id": 12, "name": "注冊資本", "pid": 5, "childrens": [ ] } ] }, { "id": 6, "name": "管理認證", "pid": 2, "childrens": [ { "id": 13, "name": "國際性管理認證", "pid": 6, "childrens": [ ] } ] } ] }, { "id": 3, "name": "履約記錄", "pid": 1, "childrens": [ { "id": 7, "name": "稅務執行情況", "pid": 3, "childrens": [ { "id": 14, "name": "是否按時繳納稅款", "pid": 7, "childrens": [ ] } ] }, { "id": 8, "name": "網貸情況", "pid": 3, "childrens": [ { "id": 15, "name": "網貸逾期", "pid": 8, "childrens": [ ] } ] } ] }, { "id": 4, "name": "公共監督", "pid": 1, "childrens": [ { "id": 9, "name": "行政處罰", "pid": 4, "childrens": [ { "id": 16, "name": "處罰信息", "pid": 9, "childrens": [ ] } ] } ] } ] } ] }
2、html頁面(test.html)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>jOrgChart異步加載</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>
<!--顯示組織架構圖-->
<div id='jOrgChart'></div>
<script type='text/javascript'>
$(function(){
//數據返回
$.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',//指定在某個dom生成jorgchart
dragAndDrop : false //設置是否可拖動
});
}
});
});
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);
//遞歸顯示
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、效果圖(打開test.html頁面后即可看到如下效果)

注意:由於數據是由ajax異步請求獲取到的,所以直接雙擊html文件打開是不行的,需要在服務器環境下運行。
