我能够使用替代JSON格式创建jstree,如下所示：
$('#using_json_2').jstree({ 'core' : {
'data' : [
{ "id" : "ajson1","parent" : "#","text" : "Simple root node" },{ "id" : "ajson2","text" : "Root node 2" },{ "id" : "ajson3","parent" : "ajson2","text" : "Child 1" },{ "id" : "ajson4","text" : "Child 2" },]
} });
但这是非常静态的.我希望它是动态的;从某种意义上说,行数可以是变量,行属性可以从数组中读取.我不想使用ajax,因为数据已经在数组中可用.
解决方法
如果您希望数据是动态的,可以使用以下代码初始化您的jstree：
$('#jstree').jstree({
'core': {
'data': arrayCollection
}
});
其中arrayCollection是一个包含动态数组的变量.例如,您的arrayCollection可能如下所示：
var arrayCollection = [
{"id": "animal","parent": "#","text": "Animals"},{"id": "device","text": "Devices"},{"id": "dog","parent": "animal","text": "Dogs"},{"id": "lion","text": "Lions"},{"id": "mobile","parent": "device","text": "Mobile Phones"},{"id": "lappy","text": "Laptops"},{"id": "daburman","parent": "dog","text": "Dabur Man","icon": "/"},{"id": "Dalmation","text": "Dalmatian",{"id": "african","parent": "lion","text": "African Lion",{"id": "indian","text": "Indian Lion",{"id": "apple","parent": "mobile","text": "Apple IPhone 6",{"id": "samsung","text": "Samsung Note II",{"id": "lenevo","parent": "lappy","text": "Lenevo",{"id": "hp","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","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.
