如果希望数据是动态的，则可以使用以下代码初始化jstree：
$('#jstree').jstree({ 'core': { 'data': arrayCollection }});其中 ArrayCollection的 是，则为您的动态数组变量。例如，您的arrayCollection可能如下所示：
var arrayCollection = [ {"id": "animal", "parent": "#", "text": "Animals"}, {"id": "device", "parent": "#", "text": "Devices"}, {"id": "dog", "parent": "animal", "text": "Dogs"}, {"id": "lion", "parent": "animal", "text": "Lions"}, {"id": "mobile", "parent": "device", "text": "Mobile Phones"}, {"id": "lappy", "parent": "device", "text": "Laptops"}, {"id": "daburman", "parent": "dog", "text": "Dabur Man", "icon": "/"}, {"id": "Dalmation", "parent": "dog", "text": "Dalmatian", "icon": "/"}, {"id": "african", "parent": "lion", "text": "African Lion", "icon": "/"}, {"id": "indian", "parent": "lion", "text": "Indian Lion", "icon": "/"}, {"id": "apple", "parent": "mobile", "text": "Apple IPhone 6", "icon": "/"}, {"id": "samsung", "parent": "mobile", "text": "Samsung Note II", "icon": "/"}, {"id": "lenevo", "parent": "lappy", "text": "Lenevo", "icon": "/"}, {"id": "hp", "parent": "lappy", "text": "HP", "icon": "/"}];最后，您的html文件应如下所示：
<html> <head> <title>JSTree</title> <link rel="stylesheet" href="dist/themes/default/style.css" /> <script src="dist/libs/jquery.js"></script> <script src="dist/jstree.js"></script> <script> $(function() { var arrayCollection = [ {"id": "animal", "parent": "#", "text": "Animals"}, {"id": "device", "parent": "#", "text": "Devices"}, {"id": "dog", "parent": "animal", "text": "Dogs"}, {"id": "lion", "parent": "animal", "text": "Lions"}, {"id": "mobile", "parent": "device", "text": "Mobile Phones"}, {"id": "lappy", "parent": "device", "text": "Laptops"}, {"id": "daburman", "parent": "dog", "text": "Dabur Man", "icon": "/"}, {"id": "Dalmation", "parent": "dog", "text": "Dalmatian", "icon": "/"}, {"id": "african", "parent": "lion", "text": "African Lion", "icon": "/"}, {"id": "indian", "parent": "lion", "text": "Indian Lion", "icon": "/"}, {"id": "apple", "parent": "mobile", "text": "Apple IPhone 6", "icon": "/"}, {"id": "samsung", "parent": "mobile", "text": "Samsung Note II", "icon": "/"}, {"id": "lenevo", "parent": "lappy", "text": "Lenevo", "icon": "/"}, {"id": "hp", "parent": "lappy", "text": "HP", "icon": "/"} ]; $('#jstree').jstree({ 'core': { 'data': arrayCollection } }); }); </script> </head> <body> <div id="jstree"></div> </body></html>每当修改arrayCollection时，都必须将arrayCollection重新分配给jstree并以编程方式刷新jstree。
